The general vulnerability of virtual mining is known as the “nothing-at stake” issue (also known as the stake-grinding attacks.Suppose an attacker who has the proportion of 50% stake is trying to construct an kblock fork. We’ve already discussed that this attack is likely to fail due to a an extremely high likelihood, which increases exponentially by k.In conventional mining techniques, a failed attempt is a major chance cost because the miner could have earned mining profits during the mining process rather than spending resources in mining on the failed attack. buy Opportunity Seekers Email  database

Through virtual mining, this cost opportunity doesn’t exist. The miner is able to utilize his stake for mining the longest chain in the world as they attempt to make an fork. If their fork succeeds it will have consumed a significant portion part of the stake. Should it fail, evidence of its failure won’t be recorded in the final chain. Opportunity Seekers Email lists

Therefore, rational miners could be constantly trying to split the chain. Many attempts have been made to tackle this problem. The majority of virtual mining platforms have been more assertive in using checkpointing to stop lengthy forks, however as previously mentioned it’s more of a loop around an uncentralized consensus protocol. marketing database Opportunity Seekers Email

In the case of Ethereum (an altcoin which was introduced in mid-2015, which we’ll be discussing in chapter 10) A idea known as Slasher permits punishment for miners who try to split the chain. In Slasher the process of using stake to mine, you must sign the current block using the private key that corresponds to the transactions comprising the stake that the miner holds. If a mining operator makes use of the stake that he signed to sign two different chains (neither of that is a prefix of one), Slasher allows miners to add these signatures later within the chain to prove of their behavior and receive some of the stake as a reward. Although this may be an efficient solution, the particulars for the procedure are complex and have yet to be successfully implemented.

Another countermeasure that could be in place is the fact that, as we’ve witnessed for mining systems that are traditional miners might do not have the motivation to strike because it would cause harm to the system and weaken their stake even if the attack proves successful.

There are other disadvantages to virtual mining.Two additional disadvantages are worthy of noting. The first is that certain kinds of virtual mining even in the absence stake-grinding, could make certain types of attacks less difficult since it’s feasible for users to “save up” for a explosion in mining. For instance, a huge amount of coin-stake could be pooled in order to allow an explosive surge in mining, which could, for instance, start an alternative fork. This is even possible using a system such as Slasher is employed to stop mining across two chains simultaneously. To prevent this kind of attack Peercoin restricts the age limit to 90 days when calculating coin-age. marketing database Opportunity Seekers Email

Another issue is that if a mining user using a virtual mining system achieves 51% or more of stake, they are able to keep it for a lifetime by mining on the top that of their blocks. This is effectively becoming the owner of this block chain. Even if a stake comes up through mining rewards or transaction fees and transaction fees, the 51% miner will get the new stake, and their portion of the stake will gradually increase to 100 percent. In traditional mining even if the 51% miner is present, it is possible that a new miner will emerge with greater mining equipment and resources and decrease the number of miners. When mining virtual, it is more difficult to prevent this issue. Opportunity Seekers Email lists

Virtual mining is still a bit controversial within the main Bitcoin community. There is a belief that security requires burning of real resources, which requires real computing hardware and real power to discover the solutions to puzzles. If this theory is true that the apparent inefficiency of the verification of work system can be understood as the price of the security you receive. However, this theory hasn’t been established, just like the security of virtual mining hasn’t yet been established.

In sum there are a lot of things that one could modify about Bitcoin’s mining system This has been an area of intense research and ingenuity. To date, however none of the options appears to have proven theoretically sound and gained an actual use. For instance, although Scrypt is a well-known option for altcoins, it’s still not reached ASIC resistance and its value isn’t certain. It’s possible that alternative mining algorithms will be successful in the near future. In the end, Bitcoin itself came after years of unsuccessful attempts to develop a cryptocurrency. It was able to find the perfect place between good design and pragmatic trade-offs. buy Opportunity Seekers Email  database

Bitcoin as a Platform

In the previous chapters we discussed the technical foundations of Bitcoin and discussed how it could be used as an alternative currency. We’ll now look at other applications that can be built using Bitcoin as the central component. Certain of them rely on Bitcoin as it is and without modifications and many would need only minor changes. Opportunity Seekers Email  id list

We’ve selected these applications based on the combination of practical utility as well as intellectual curiosity. The list isn’t necessarily comprehensive However, observing how these apps work (or could function, given that they are mostly thoughts or suggestions) can provide insight into the various ways that Bitcoin’s capabilities can be used to benefit others.

Bitcoin as an Append-Only Log

It’s beneficial to think of Bitcoin as an append-only log — the data structure on which it is possible to write new data and after we’ve written data, is impervious to manipulation and accessible for all time. Additionally, we have a secure concept of order that allows us to determine whether a particular piece of data was recorded to the log prior to or following another. This order is derived from block hash points, not the block’s timestamps. the timestamp of a block’s data may actually be less (earlier) amount than the one it preceded. This is because miners may be deceived about timestamps, miners’ clocks might not be in sync, and there may be delay in the network. However, if the block time stamp appears not to match by more than couple of hours, other miners will not accept it, which means we can trust that the timestamps are about right. We’ll find out that these properties can very useful. Opportunity Seekers Email consumer  database

Secure timestamping. The append-only log is used to construct an encrypted timestamping system using Bitcoin. We need to prove that we have the value of x at a particular date T.We may not wish to reveal xat T.Instead we want to reveal x when we actually complete an actual proof. This could be a lot later than T(and of course , if we had known it at T, we are still aware of it even after T). Once we’ve done the proof, we’d like that proof to remain in place. Opportunity Seekers Email lists

Remember from Chapter 1 that we could use hash functions to bind the data. Instead of publishing the data, we can commit it to hash functions.

data x we want to prove the validity of, we could publish only the hashH(x) to the block chain. The
The properties of the function will ensure that we won’t find another value using the
the same value, yxsuch that H(x) equals H(y).We can also count on the logical fact that the hash the number x
isn’t able to reveal any information about x, so it is a part of a group of people with high
min-entropy is when it’s enough variable. If xd’s property isn’t present and we want to select one.
random number r with high min-entropy, and employ H(r | x)as the commitment, as we did in Chapter 1.

The idea behind this is that we release just x) as a hash H(r | x)at time T. Then at some time later we can show the rand x.Anybody is able to look through the append-only log and become certain that we have been aware of x at the time the data was published H(r | x),because there is no possible way to generate the data.

Uses of timestamping. What are the possibilities for this kind of time stamping that is secure? One possibility is to establish prior knowledge of an concept. Let’s say we want to prove that an idea we applied for a patent on was in our minds way earlier. This could be done through the publication of the design document or diagram when we first began thinking of the idea without telling anyone about the reason behind the idea. In the future, when we file for our patent, or when we announce the idea it is possible to release our original document and data and anyone could look back to confirm that we knew about it before we made the agreement to the idea. Opportunity Seekers Email consumer  database

It is also possible to show that another person has received an email we’ve sent them. Imagine that Alice employs Bob to do an assignment in programming The contract stipulates that Bob deliver his code to Alice at a specified date. Both parties wish to be sure that in the event of dispute in the future regarding the fact that Bob did the work or whether the code was performed according to the specifications, they can provide evidence of the work submitted and the date at which it was submitted. To do this the parties can decide to release the hash of Bob’s submitted work that is signed jointly by all parties. If one of them later lies about what they submitted , or the date it was submitted they are unable to show them wrong (say for instance, in an arbitration court) by disclosing the information that was used to create the hash. Opportunity Seekers Email lists

Other interesting ideas can be constructed by using secure timestamps. There’s even a whole publicly-keyed signature method (called”the Guy Fawkes signature scheme) which merely uses the functions of hashing and also an append-only log. It doesn’t need any of the bulky cryptography used in signatures with public keys. buy Opportunity Seekers Email  database

Attacks on Proofs-of-“Clairvoyance”. One thing we aren’t able to do using secure timestamps alonehowever it would be wonderful to be able to do it be able to prove that clairvoyance can forecast the future. It’s plausible. It’s possible to release a promise to the details of an event set to happen (such as the outcome of a sports event or an electoral vote) and then, later, disclose that information to show that we knew the outcome prior to the time. What happens if this isn’t working? Opportunity Seekers Email  id list

In the latter part of 2014, in the final game during the final match of the World Cup, someone used this technique in order to “prove” that FIFA, the organization that hosts the World Cup, was corrupt. Following the conclusion of the match an unidentified Twitter account gained a lot of attention for tweeting about various instances that took place during the match, and timestamped prior to the moment the match began.For instance, it correctly posted that Germany were going to win in extra time, and that Mario Gotze would score. It appears that either the account’s owner Twitter account is able to predict the future, or that the game was fake. In reality, the account tweeted every possible outcome prior to the match began. For each player in the game the account tweeted a message that predicted that they would score. There were tweets for each possible final score of the game, and on and for the rest of (see figure 9.1). When the match was over all the fake predictions were removed which left the Twitter account with only real “predictions.” Opportunity Seekers Email lists

The same type of attack can be used against any trusted timestamping device. It is as simple as committing to a range of outcomes and only disclose the agreements that prove to be valid. That means that if you do actually have the capability to forecast the future and desire to prove it you need to be able to prove that you have timestamps on the specific prediction rather than several predictions. If you’re publishing commitments based on hash it is difficult to accomplish. This is the case especially in Bitcoin because our time stamping system is secure and does not connect commitments to any private identity of an individual. If you do not disclose your commitments, it’s simple to release a huge number of commitments, and those you do not reveal are unable to be identified back to the person who made them.

Time stamping securely the old-fashioned way. Here’s an easy, low-tech method to perform secure timestamping: release your hash in a newspaper or other medium that is seen by a large portion of people, and then purchase an advertisement. The archives of newspaper issues from the past are stored in libraries as well as on the internet. This gives you a high level of confidence that you had the information was in the newspaper on the day it was released. In the future, if you wish to disclose the information that you have committed, you could even make a new advertisement and publish the data to the newspaper in which you published the data. Opportunity Seekers Email consumer  database

Secure timestamping with Bitcoin. If we want to make use of Bitcoin rather than newspapers to timestamp where do we place the hash committment? In the transaction? Or directly in the block?

The simplest method (and the one that people thought of first) is to instead of transferring cash to the haveh of the public key simply send funds to the haveh you’ve created in your personal data. The process “burns” those coins, and makes them ineligible for spending and therefore permanently lost, as you don’t have the private key that corresponds to the account. To reduce the cost you’ll need to transfer only a small amount like just one single satoshi (the minimum transaction value of Bitcoin). Opportunity Seekers Email lists

Although this strategy is easy to implement, the requirement to burn the coins is a drawback (although the amount of money burned will likely be small compared to the transaction costs). Another issue lies in the fact that Bitcoin miners do not have a way to tell if the output of a transaction is not able to be spent and therefore they have to track the transaction for a long time. The Bitcoin community has a negative opinion about this approach due to this reason. Opportunity Seekers Email  database free

A more sophisticated method known as CommitCoin permits you to encode your data to an encrypted private key. Remember that in Chapter 1 in which we stated: “With ECDSA, a reliable sources of randomness are crucial because a source of bad randomness could compromise your keys. It is logical to think that if you choose to use poor randomness to generate keys and the key you create will not be safe. However, it’s a flaw in ECDSA that even if you make use of poor randomness in the process of creating the signature, with your perfect key, this will also expose the private keys of yours.”

CommitCoin utilizes this property. We create a new private key that encodes our commitment . Then we obtain its public key. We then send a tiny transaction (of maybe 10,000 satoshi) to the address and then return it in two pieces with a total of 1,000 satoshi. In addition, when sending it back, we employ the same randomness each time to sign the transaction. This allows anyone viewing the chain of blocks to calculate the secret key that is the one that contains the commitment, using two signatures.

As opposed to encoding your commitment into the key public, CommitCoin does not require you to burn coins , and allows miners to keep track of the unspendable output for a long time. It is however extremely complex. marketing database Opportunity Seekers Email

Opportunity Seekers Email  database

Unspendable outputs. In 2014, the best method to perform Bitcoin timestamping is to use an

OP_RETURN operation that results in an output that is not able to be spent. The OP_RETURN instruction immediately returns with an error, ensuring that the script will never be successfully executed and the information that you input is not considered. In Chapter 3 it could be used to prove burn, as well as to encode data of any kind. In 2015, OP_RETURN allows for 80 bytes of data transferred and will be more than sufficient to create an output from a hash functions (32 bytes for the SHA-256). Opportunity Seekers Email  id list

This technique prevents the accumulation of bloat in the output of unpaid transactions because miners trim the outputs of OP_RETURN. The cost of this commitment is basically the price in one fee per transaction. In 2014, the average transaction fee is just one cent. The price can be cut further through the same commitment for multiple value. Since the end of 2014, there are several websites solutions that can help you with this. They gather a variety of commitments from various users and then combine them into a massive Merkle tree. They then publish an non-spendable output that contains the Merkle tree’s root. This is a promise to all the data users want to timestamp for the day. Opportunity Seekers Email  database free

Illicit Content. One drawback of the ability to write random data into the chain of blocks, is users could abuse the feature. In the majority of nations, it is unlawful to distribute and/or possess certain types of content, such as child pornography. The penalties could be very severe. Copyright laws also limit the distribution of certain types of media. Opportunity Seekers Email lists

Certain enough, a number of people have attempted to do things similar in order to “grief” (i.e., to annoy or harass) members of the Bitcoin community. For instance, there’s been reports of pornographic links posted in Bitcoin’s Bitcoin block chain. The aim of these grievers are to render it unsafe to download the block chain to your hard drive and operate a full node because doing so could be a matter of storing and transmitting information which is prohibited.

There’s no effective method to stop people from writing any kind of data to the block chain of bitcoin. One possible countermeasure is to only accept Pay-to-Script-Hashtransactions. This will make it slightly more costly to input random data however it wouldn’t hinder it from happening.

Thankfully the law isn’t an algorithm. It’s tempting at “hack” the law by techniques that can produce unintended or unintended results However, it isn’t an easy task. The law is intended to be read by humans, and they incorporate elements like intention. For instance, U.S. Code 2252, the part that is part of U.S. federal law that is pertaining to the possession, distribution and reception of child pornography. It employs the phrase “knowinglypossesses, or knowinglyaccesses with intent to view” when discussing prohibited activities (emphasis the word “knowingly” in our case). Opportunity Seekers Email  database free

It’s also important to remember that, due to the limitations on size we mentioned earlier, data like images (except maybe tiny images) can’t be directly uploaded to the Bitcoin block chain. They’ll have to be hosted elsewhere or be written as links to the chain or encoded in a complex manner over multiple transactions. Additionally, the majority of Bitcoin clients don’t come with the capability to read and decode the data that’s written into transactions or even data encoded in multiple transactions.

Overlay Currencies. The positive aspect is that because we can write whatever data we like into Bitcoin We can also develop a brand new currency system based on Bitcoin without having to design an entirely different consensus method. We could simply utilize Bitcoin in the current state as an append-only log and then write all the information we require for our new system of currency straight to bitcoin’s Bitcoin blockchain. This is referred to as something we refer to as an “overlay currency”. Bitcoin is the primary basis, and the data of the currency overlay is written to Bitcoin’s Bitcoin block chain with unspendable transaction outputs. Opportunity Seekers Email lists

Naturally, Bitcoin mining companies will never be able to verify what you write into the block chain because they don’t understand (and do not care!) what data you input is valid according to the rules of the new currency. Everyone can put anything there , provided they take on the Bitcoin transaction costs. Instead, you’ll need to create more complex logic to validate transactions using the new currency and this logic has to be implemented in every client who is involved in the exchange or transfer of the currency. Opportunity Seekers Email quality  lists

For instance, in the case of an overlay currency, miners cannot refuse double spending. Instead, each user of the currency overlay must take a look at what’s written in the blockchain. In the event that an overlay transactions tries to spend an overlay currency that’s already spent this second transaction shouldn’t be considered. Because of this, there is no any such thing as a light SPV client for overlay currencies. marketing database Opportunity Seekers Email

Opportunity Seekers Email  listing

Counterparty is an important overlaid currency. The majority of Counterparty transactions are recorded to Bitcoin’s Bitcoin Block Chain. In 2014, between 0.5 percent or 1% Bitcoin transactions included Counterparty information. Counterparty also has a more extensive and robust feature set than Bitcoin. It is a good idea to consider that Counterparty doesn’t need to come up with a new consensus algorithm and because Bitcoin miners don’t have to be aware of the Counterparty regulations, it are able to instead concentrate on creating interesting options like smart contracts, user-defined currencies, and much more. It is possible that the Counterparty API can be much bigger in scope than Bitcoin API because Bitcoin miners don’t have to know about it or be a part of it. buy Opportunity Seekers Email database online

The prospect of creating a new currency that doesn’t require to establish an entirely new consensus system is attractive. There is no need to convince new miners to join your system. Moreover, you can even add new systems depend on Bitcoin (for instance they’re subject to the same requirements for fees like the other Bitcoin transactions. The method is also inefficientsince the nodes that are part of the cryptocurrency overlay might need to process lots of data, because Bitcoin nodes aren’t able to make these transactions more secure for you.

Bitcoins as “Smart Property”

We’ll now discuss using bitcoins as a symbol for something different from a unit of currency within bitcoin. Bitcoin system.

In chapter 6 that you are able to trace ownership of the value of Bitcoin’s Bitcoin process over the course of time simply by following the graph of transactions. Be aware of the caveat that there’s not anything called an actual “bitcoin” per se -only unredeemed transactions, which are referred to as coins. Every bitcoin has a past that anyone can see within blocks chain. The history of a bitcoin goes all the way to the coinbase transaction where the coins were first created. We’ve discussed this before this can be detrimental to privacy, as you can frequently track the ownership of coins in this manner. Opportunity Seekers Email lists

Fungibility.This is also an interesting fact: bitcoins aren’t fungible.In economics an item that is fungible is one in which all units are equal and are able to be substituted against one another. For instance, gold is fungible because an ounce of (pure) gold is able to be used to replace any other or equal amount of gold. However, this may not be the case of Bitcoin because each bitcoin is different and has a distinct background. Opportunity Seekers Email quality  lists

In some instances, this history could not be a factor However, if this history is significant to someone you wish for trade, then it might mean it is that the 1.0 bitcoin isn’t identical to your 1.0 bitcoin. Perhaps they won’t want to swap theirs for yours due to the story of their coin to the history of your coin. In the same way, for instance, just since coin collectors are fond of old coins, in the future, bitcoin enthusiasts might put a special worth on coins from the genesis block or other block early in the history of Bitcoin.

Smart Property. This property with no fungibility could be beneficial? We’ve seen how it could be detrimental to privacy due to the potential of deanonymizing users. In this section , we’ll examine the reasons why it could also be beneficial to give an explanation to the background of bitcoin.

Let’s consider what it means to interpret the background of the ordinary physical currency that is not physically accessible. If we were to incorporate metadata into offline currency. In reality, some individuals already use this method. For instance, they prefer to put messages on banknotes. This is usually done in a humorous manner or as a political protest. It doesn’t generally affect its value. notes as it’s simply a fun thing to do.

But what if we could have authenticatedmetadata attached to our currency — metadata that cannot easily be duplicated? One method of achieving this is to add a cryptographic signature to your metadata and then link this data to the serial number of the banknote.Opportunity Seekers Email quality  lists

What is this money could use it to do? If a baseball team decides to use dollar bills for tickets. So, they do not need to endure the trouble creating their own ticket, and making sure that nobody could print fake tickets. They could also say that the New York Yankees could simply claim that the dollar that has a specific serial number is now an admission ticket to a certain game and in an exact location. These dollars would have to be handed out in similar way that tickets printed on paper are distributed, for example by sending tickets to fans whenever they purchase tickets on the internet. The person who holds the note is entitled to go into the stadium, to take a seat in the designated area and watch the game with no other questions being asked. The banknote constitutes the tickets! Opportunity Seekers Email lists

To give the impression of authenticity to add authenticity, to add authenticity, Yankees could opt to use digital signatures. They’d sign a note that contains the specific game date, seat number, as well as the code number on the billand then stamp the message and signature across the bank. A 2D barcode is an ideal format for this information (See the figure 9.4). Alternately the stadium could have an inventory of the serial numbers along with the seats numbers for every game. The database could be scanned for this information every time you attempt to go through the gate. This eliminates the requirement to stamp banknotes. marketing database Opportunity Seekers Email

What do we get from this? Today, currency can symbolize various things. Apart from the instance of a sporting ticket There are numerous other possibilities. We have the property of anti-counterfeiting that banknotes already possess. Governments are working hard to make sure that it’s impossible to duplicate an actual banknote! In addition, the original value of the currency is kept. Once the person is able to redeem his ticket note is able to be used as regular currency. It could be a hassle in the event that everyone would like to stamp metadata on the currency but the issue is solved if we utilize the database method. buy Opportunity Seekers Email database online

Of course, the value of this new data is contingent on our faith in the issuer who signed it. It must be known that there is one specific key that is used to authenticate Yankees tickets – and download Yankees database to be able to appreciate its worth as tickets. For anyone else they could be a fraud.
The bill would look like the shape of a dollar bill. However, that’s not a problem. This is actually an attractive item as soon as the ticket has served its purpose, it’s able to be reintroduced as a normal dollar bill.

Colored coins.Can be done digitally over Bitcoin? We’d like to retain Bitcoin’s wonderful features, such as the capability to transact online, quick transaction settlement and no dependence on banks. purchase Opportunity Seekers Email  lists

The concept is to stamp bitcoins with the “color”, and track the color stamp as the coin’s ownership changes as we can stamp metadata onto physical currency. A bitcoin that is stamped with a color continues to function as a legitimate bitcoin however, it also contains this metadata. Opportunity Seekers Email lists

In one transaction, known as”issuing,” in one transaction, called the “issuing” transaction, we’ll include additional metadata that will declare some of the outputs have specific colors. A good example can be seen by Figure 9.5. In one transaction that the issuer issues five “purple” bitcoins in one output of the transaction, while the other output will be regular uncolored bitcoins. Another person, possibly with a another signing key, issue “green” bitcoins in a separate transaction. These colors are used for convenience, but in actual they are simply bits of string. The only aspect that is relevant is that coins with identical color and value are of equal.

Bitcoins now come with different colors that go with the different colors. You can continue to do the regular things we normally do when we use bitcoin transactions. It is possible to have a bitcoin transaction which takes a number of inputs such as green and purple coins, and some other coins, and then shuffles the pieces around. It could also have outputs that keep the color. There might be some kind of metadata in the transaction in order to determine which color is assigned to what output of the transaction. You can divide a transaction that produces four coins of green into smaller ones. In the future, we can join multiple green coins to create one large green coin.
OpenAssets.As of 2015 the most popular suggestion to implement this feature in Bitcoin is known as OpenAssets. Assets are issued with an address that is specifically designed for Pay-to-Script-Hash. If you wish issues colored coin you must first select the P2SH address you want to use. Any coin that is transferred through that address but comes without color will depart with the color assigned by the address. To make this a valid it is necessary to announce the address on a public platform. There are several exchanges that keep track of the addresses that confer colours to coins. Since coins are able to go through multiple color-issuing addresses and have multiple colors, and that’s perfectly fine. purchase Opportunity Seekers Email  lists

If you are involved in an activity that requires the use of colored currency, you will need to add a specific marker output. This is a guaranteed non-spendable output, similar to the one we have used to timestamp data commitments. The metadata contained in the output of the marker contains information about how the color value will be split into the various outputs.

Bitcoins are bitcoins in themselves.

Domain Names.As an example to conclude think about the use of colored coins to fulfill certain functions of the current Domain Name System: tracking the ownership and transfer of domain names, as well as an IP address mapping for domain names. The market for domain names has numerous interesting features There are an infinite number of namesavailable, they have a variety of worth based on their recollection and other variables in addition to the fact that the same name could be very useful to different individuals. You can utilize colored coins for domain name registration, as well as the other functions we have listed. But, facilitating this particular application has also been the primary focus of a well-known altcoin known as Namecoin that we’ll take a discuss in depth in the following chapter. Each method has advantages that are distinct: with colored coins, you have the security offered by the block chain of Bitcoin, whereas using an altcoin, it’s much simpler to implement the complicated algorithm required for the ownership of domain names, transfers as well as DNS address mapping. purchase Opportunity Seekers Email  lists

Secure Multi-Party Lotteries in Bitcoin

In the next section, we’ll discuss hosting the “coin flip” game in Bitcoin. In the beginning, we’ll begin with a description of how we can play offline the game we’re trying to create.

Alice and Bob would like to bet five dollars. They each agree to the betting ahead of time, and also the method to determine the winner. Bob will throw an airborne coin and, while it’s spinning Alice will call out “Heads” or”Tails”. If the coin falls on the ground, both are aware of who was the winner of the bet and both are confident that the result was not random and neither could influence the result. Opportunity Seekers Email lists

The order of the steps used in the ceremony, as well as the mechanics of flipping coins play an important role in convincing both sides they are playing fair. One drawback to this system has to do with the fact that each party need to be in the exact location simultaneously. Additionally, both parties must trust that the person who loses will be compensated. In today’s world of the internet we’d love to see an online lottery that’s just equally “fair”, but also solves the issue of making sure that the loser is paid.

At first glance, this may appear as a bizarre and limited program worth exploring in depth. It’s funny that Bitcoin-based betting applications like Satoshi Dice — which are based on a trusted entity in contrast to the system we’d like us to developare extremely well-liked and, in some instances, account for the majority of Bitcoin transactions that occur on the network. buy Opportunity Seekers Email targeted  list

The reason we are interested to investigate cryptographic coin flipping however, is because it appears that if we are able to create a secure protocol to it, we could use these techniques to create other useful and interesting protocols. Cryptographers research “secure multiparty computation” where two or more untrustworthy parties have their own information and wish to calculate the result based on their entire data, but without disclosing the information to the other. Imagine a sealed bid auction with an auctioneer you trust. In many cases, these calculations need to be randomized, for example to break up bonds. Additionally, we might need the outcome of the calculation to determine an unalterable monetary result in a manner. Maybe we’d like to guarantee that the bidder who wins the auction will pay the seller. Maybe we want to make sure that the vendor’s (smart) property auctioned will be transferred automatically to the winner. Or, perhaps we would like to penalize those who do not adhere to the procedure.

Also an extremely secure multi-party lotto is an ideal setting where you can study an extremely powerful concept of participants who have mutually distrust with sensitive inputs working together to execute programs that have the ability to manipulate not just bits but as well money. Opportunity Seekers Email lists

Coin Flipping Online. The first hurdle is to replace this “coin flip” mechanism with an online version. Let’s say that we have three players, Alice, Bob, and Carol and they all are looking to pick either a number of 1 2, 3 or 3 with the same probabilities. This is one way to implement the method. Each person chooses a huge random number — Alice picks x, Bob y, and Carol Z. They share their numbers and determine the results by using (x + y Z) 3 . Opportunity Seekers Email  database free

Opportunity Seekers Email business database

If they all picked their numbers separately This could be effective. But keep in mind that we’re doing this on the internet, so there’s no way to demand that all of them broadcast their number “simultaneously”. Alice may wait until she has heard the numbers of Carol and Bob before sending her own. If she chooses to do this, it’s easy to imagine how easy it is for her to tailor the final broadcast however she’d like. It’s impossible to design the procedure to convince everyone that there was no other parties have cheated. Opportunity Seekers Email  database providers

To address this issue, we could once more utilize hash commitments. In the beginning, each chooses a random number, and then publishes the hash of that number. Once that’s done the participants reveal the random number they selected. They then make sure that the numbers revealed have a hash to the numbers published in the initial step, and then calculate the final results using the three random numbers, as illustrated in figure 9.6.

Round 1:

Each participant picks a random string. Alice chooses x. Bob chooses y, and Carol chooses Z.

The parties will publish H(x), H(y), H(z) respectively.

Each party makes sure to ensure that H(x), H(y), H(z) are all distinct values (otherwise cancels this protocol).

Round 2: buy Opportunity Seekers Email targeted  list

Opportunity Seekers Email database free download
Opportunity Seekers Email database free download

The three sides show their respective values, the three parties reveal their values, namely x, y and z. Opportunity Seekers Email lists

Each party makes sure whether the values revealed agree with the hashes that were published in Round 1.

The result will be (x + y) 3.

Figure 9.6:Using hash-commitments to create an equitable random-number generator.

This protocol is easily extended to accommodate the participation of any number of parties.

The reason for this protocol to work is twofold. One, because the inputs to hash are x, y, and z are massive random numbers, nobody is able to predict the other’s inputs until after the first round. In addition, if (say) Alice chooses her input randomly, as per this protocol, then she is certain that the output will be random, regardless of the fact that Bob and Carol select the inputs they choose randomly.

Fairness.What happens if someone isn’t able to disclose their commitment? In round two of this protocol let’s say Carol does not reveal her secret till Alice Bob and Alice Bob have disclosed their secrets. Carol prior to revealing her own knows that she’s likely to be losing if she discloses hers. Therefore, she may choose not to divulge her random numberand then claim that she forgot it , or even pretend to be offline. Alice and Bob might be suspicious, but they’d be left with no alternative. Opportunity Seekers Email lists

We’d like to see a system where anyone who commits to a promise is compelled to disclose it within a certain period of time. The cryptography characteristic is known as fairness. Bitcoin gives us an outstanding mechanism for this.

Let’s imagine that Alice would like to make an obligation to commit to a certain time to Bob, as well Bob is the only person with an interest in the issue. The first step is that Alice creates an obligation as an Bitcoin Transaction Output script which stipulates that it may be used in two ways. One method is through an agreement signed by each of Alice Bob and Bob. Another way to use it is by signing from only Alice however, only if she divulges the random numbers she has chosen. If Alice’s random number is x, then the scriptPubkey includes an integer value H(x).

Then, Alice and Bob both agree to a deal that will pay this bond back in full to Bob (which can be one of two ways in which it can be used). What is the reason why Alice be willing to sign this agreement? The transaction comes with an nLockTimevalue which guarantees Bob will not be able to take the bond back before a certain date t.Since Alice plans to reveal her commitment value prior to the time and then claim the bond and then claim it back, it’s safe to let her to sign the transaction. buy Opportunity Seekers Email targeted  list

If Alice decides to leave without revealing her worth, Bob can claim the bond when t.This isn’t a requirement for Alice to disclose her pledge, however she’ll lose the whole bond she put up. The guarantee that she’ll divulge her secret value is contingent on the amount she’s willing to invest in the bond.

scriptPubKey: Opportunity Seekers Email  database free

Figure 9.7 The output of the transaction scriptPubkey and scriptSigs are used to create a timed hash committment. Opportunity Seekers Email  database providers

How can we utilize this timed hash committment to run the secure lottery? We’ll use the same structure but instead of simple hash commitments we’ll be using this type of timed obligation. Anyone who doesn’t disclose their random number before the deadline is forfeited the security deposit to compensate the other participants. The process of revealing the value of random is just a matter of recovering this bond, by providing password x.

This lottery method can be implemented over the back of Bitcoin. It’s not easy as the hash timed obligations require multiple transactions that are not standard. If there are more than one party participating in the game, n2 commitments are necessary since each of the parties must sign an obligation for the other party. Players must escrow more than they actually bet. It is acceptable for a limited amount of players and there are other options with more performance. In addition, it acts as a proof that even seemingly unattainable methods like flipping a virtual coin on the internet, and penalizing an individual for aborting the protocol is possible with the Bitcoin world.

9.4: Bitcoin as Public Randomness Source

In the previous part we discussed that a collection of individuals can collectively decide on an appropriate random value. In this part, we’ll discuss about how to use Bitcoin to create random values that are fair to everyone in the public. Opportunity Seekers Email lists

What is the reason we would want this? Let’s consider a few instances of software that depend on public sources of random values.

NBA draft lottery.One instance that happens every springtime throughout the U.S. is the NBA draft lottery. The teams from the NBA gather and randomly select — with a weighting in relation to the way each team performed during last season’s game – the order in which teams are able to choose the best amateur players from across the nation that are ready go into professional. The first time this happened was 1985. The lottery was broadcast on live television and involved the picking of envelopes following they were shuffled inside a spinning drum. This lottery caused some controversy due to the fact that there was a dispute over which team the New York Knicks won in the very first year and were able to draft famously sought-after centre Patrick Ewing (an eventual member of the Basketball Hall of Fame). Because the lottery was recorded on the streets of New York City, some supporters of other teams believed that the lottery was rigged for the Knicks.

There are a myriad of theories of conspiracy about the ways in which the NBA might have altered this procedure, for instance the well-known “bent corner” theory suggesting that the Knicks’ envelope was designed with its corner bent in order that the commissioner could identify it from the other ones through touch. Another theory suggests that the Knicks envelope was stored in a freezer, and the commissioner simply snatched the one envelope cold. These theories explain how difficult it is to hold a sketch such as this, and also prove it was fair. There are numerous possibilities to cheat. Think about the tricks professional magicians be able to do! Today, the lottery is held every year, and each year it results in a variety of conspiracy theories and theories that it isn’t an honest random draw. buy Opportunity Seekers Email database for marketing

U.S. military draft lottery.Amore important example is from the year 1969 where there was conscription lottery within the United States to determine which youngsters would be required to be drafted into the military forces. A majority of the participants were deployed into Vietnam. Vietnam War. A similar procedure that of that of the NBA lottery was employed and carried out by a number of members of in the US Congress in broadcast live on TV (Figure 9.8). They emptied small capsules that were labeled with the day of the year’s calendar into a large drum of plastic and then alternated making their way into the drum using their hands to take the numbers out. The men who were eligible for a draft were assigned a priority determined by the date the date of their birthday. Priority numbers determines the sequence in which they would be selected. Opportunity Seekers Email lists

The draft of 1969 is the first occasion that the lottery was used at a national level. The aim of the draft was to ensure that it made the procedure more fair (by getting it out of the hands of a multitude members of the local board for draft) and also to prove to the general public that it was not a random procedure. The lottery, however, was not successful. Within one week, the statisticians who looked at the data observed an unusual design (illustrated in figure 9.9). Late in the year, days had low draft numbers. Although the difference is insignificant but the statistical significance is significant, and likely to be by random chance. After they returned to examine the tapes it was discovered that they had rotated the drum exactly an equal number of times, which meant that the ones that began on top tend to remain on top. The mixing wasn’t enough to create an statistically random draw.

What these two instances show is that it’s incredibly difficult to create public randomness and convince people that you’ve done an excellent job. There’s a chance that the method may not be completely random and uninfluenced. There’s also the chance that even if it is random, the public will not be able to believe it. buy Opportunity Seekers Email database for marketing

Cryptographic “Beacons”.Public demonstrations of randomness with a wheel, turning dice, coins and the like have become so well-known throughout history due to them being inexpensive and simple to comprehend. However, they’re not able to cope well with massive scenarios since they’re extremely difficult for the public to verify. Even if the footage of the process appears to be authentic, some people might be skeptical that the conductor of the lottery may have used some trick of hand to alter the procedure.

Do we have a better way to do cryptographically? We can use the phrase “cryptographic beacon” to refer to a service which provides an open resource of randomness. The concept is to emit random data at a periodic rate that no one can forecast ahead of time. I hope everyone agrees that there’s no way to know the value of the beacon next, which is why everyone can trust it to deliver an accurate random value. Opportunity Seekers Email lists

If there were a perfect cryptographic beacon that could be used to play any of the lotteries that we have looked at. If you simply want to have a game of bingo in your local club, you won’t have to make use of a huge ball of numbers. If everyone trusted the beacon, you’d reduce the amount of work when compared to physical display of randomness. Opportunity Seekers Email business  database free download

Opportunity Seekers Email b2c database

Cryptographers have suggested a myriad of other methods of randomness for public use that include voter systems, no-knowledge proofs and cut-and-choose methods. Some of them can be implemented more quickly and effectively if you have an ideal cryptographic beacon. Unfortunately, we’ve not come up with a method that is perfect to set up a beacon like this at this time. Opportunity Seekers Email  database providers

This is an NIST beacon.The National Institute of Standards and Technology (NIST) has since 2011 launched its own beacon services. They claim that they generate random numbers using an intricate laboratory setup that involves two photons that are entangled. The goal is to offer certainties of the fact that these numbers will be not random as they result by a quantum mechanical process. If you believe in the principle of Heisenberg’s Uncertainty Principle as well as other widely accepted physical laws Then this is completely random and unpredictably. The system is configured in a way that it generates fresh random information every 60 seconds and includes an electronic signature on the data. The NIST beacon offers a user-friendly interface for programming applications The numbers can be read from an internet feed. buy Opportunity Seekers Email database for marketing

This quantum mechanical method is , in a sense, it is in a sense the “limit” for physical displays of randomness. However, it doesn’t solve the fundamental issue of trust. You must believe that NIST is actually carrying the process as they claim. It is essential to believe that in some building in Maryland NIST has their own laboratory which produces these numbers and don’t just stage the procedure. Also, you must believe that they don’t reserve the power to overwrite certain random numbers before publishing the results. Opportunity Seekers Email lists

There are other ways of creating beacons: natural phenomena.What is your opinion on an alternative strategy using a natural phenomenon that everyone is able to be able to observe? Perhaps we could draw on information regarding the weather for example, like the temperature that it will be on the day of tomorrow in a specific location and whether the winds is likely to be and whether or it’s going to rain. Of course, we do have some capacity to forecast the weather in advance however, not in a precise manner however, and we might utilize some of the “least significant bits” of the values measured. There is a limitation in this method, as all participants must be in the same location for the exact measurement. Opportunity Seekers Email database for sale

To stop this from happening, we can look into sunspots, which are bursts of activity that occur on our sun’s surface. Another instance of cosmic background radiation which is a type of noise that can be heard by using a radio transmitter at any point anywhere on earth; everyone can read the same amount. These are events that occur on such a massive dimension that it’s easy to believe that no one is able to manipulate the process. It’s not possible to imagine that someone could fly an spacecraft to an area of the Sun in an attempt to alter the process to win a lottery on

Earth. Therefore, these methods have many advantages: public observation as well as security against manipulation and, most of the time an acceptable degree of uncertainty.

The issue with these methods is that they’re quite slow. For instance, if your randomly generated signal is your daily high temperature then you’ll only receive one read per day. The sun’s surface isn’t subject to change frequently. In many cryptographic applications random bits are utilized for input to an algorithm known as a random generator(PRG). In order for a PRG to be secured, input has to be at least 80 bits (or more) in length. It could take some time for the 80 bits of randomness be accumulated from sources that are based on weather or Astronomy.

Additionally, you need the right expertise to determine sunspots It is therefore necessary to trust a reliable observer to release the results. There are numerous trustworthy observers and we can be hopeful that they’ll “keep each other honest”. Applications that use beacons, or the users of such apps can choose the observers they’d prefer to trust. They are also able to change observers at any point. This is referred to as “trust agility” and is possibly superior to having one entity like NIST which produces the beacon. Opportunity Seekers Email lists

There’s more to the issue that , at first glance, may appear to be simple. How can we transform real-world observations like a temperature or photos of sunspotsto a string of bits in a manner that all observers be able to access the same string of bits? You could attempt to quantify the measurement. For example you could write the temperature in Fahrenheit , and make the decimal number the first as the beacon’s output. However, unless each observer’s thermometer is not incredibly exact there will be instances that some observers will interpret that temperature to be (say) 62.7 while others will interpret that as 62.8. It appears that regardless of what natural phenomenon we select and the protocol we choose to use there will exist “corner cases”. For a beacon that uses cryptography, even a small chance of measurements that are inconsistent could be unacceptable since it could result in the random bits generated by a PRG to be entirely different. Opportunity Seekers Email database for sale

Financial data.Asimilar idea is to utilize feeds of financial information such as the prices of stocks. They are, in fact, publically observable values. In contrast to natural phenomena, they are recorded as digital values and the issue of inconsistent data is solved. There’s an excellent evidence that suggests it’s difficult to predict the fluctuation in price of stocks: If you could determine within a single penny how much the stock you’re interested in will appear in the New York stock exchange tomorrow and you can earn a substantial profit as an investor on a daily basis. One could attempt to alter the price of the stock by purchasing or selling the stock to bring the price to a particular price, but that comes at an actual cost that isn’t a possibility to avoid.

However, this strategy faces the issue of trusting a trustworthy third party, which is an exchange. Although the stock exchange is a powerful incentive to show that it’s trustworthy and acting honestly, the possibility may still be a suspicion that they may attempt to lower the value of a share by a penny (for instance, inserting their own orders to the stock exchange’s order books) in the event that it allows them manipulate the price of a lottery.

In all the options we’ve considered it’s hard to stay clear of having a trusted person who exerts influence over a crucial aspect or process. Opportunity Seekers Email lists

Making use of Bitcoin as an Beacon.Fortunately one of the themes throughout this book is that Bitcoin is an interesting technology to remove the centralized trust of protocols in ways that we did not initially think feasible. Could we utilize Bitcoin as a beacon that is random? We’d like to collect random information in bitcoin’s Bitcoin block chain, while preserving all the characteristics of decentralization that make Bitcoin its own currency so appealing. Opportunity Seekers Email business  database free download

Remember that miners have to make a variety of random hash value values as trying to identify the most profitable block. It could be that this means that nobody can know or determine the value of the next block will be without actually performing the mining. Naturally, the initial parts of any block will be zero however it is apparent that, if you make the right assumptions it is the sole way to know the remainder of them is to alter them by locating an enticing block, and then carefully removing it. Opportunity Seekers Email address lists

This makes it easy to convert the chain of blocks into a beacon of randomness. For each block in the chain we add an “randomness extractor” to the value of the block header. A randomness extractor roughly being an algorithm that has been designed to compress all of the random entropy from the input into one random string. Each time a block gets published, we receive a an updated beacon’s output.

Assessing the security of the security of a Bitcoin beacon. Let’s suppose you’re part of an online lottery, whose results are dependent on the results of the Bitcoin beacon in a future block that will be a part of the height H within the chain of blocks. There are N participants who are participating in this lottery and each is betting on B bitcoins. If you’re also a mining and you happen to be lucky, you could win and discover a hash puz
