Isle of Man Blockchain proof of concept project

A few days ago the Man government revealed that it is working on a Isle of Man blockchain proof of concept project.

Announced on the Financial News, this plan started thanks to a collaboration with the blockchain startup Credits.

The Blockchain proof of concept aims at exploring the possibility of the distributed ledger to be used for Internet of Things (IoT) devices.

How the Isle of Man Blockchain proof of concept project works

Credits co-founder Nick Williamson explained that this idea was born to assign unique identities to devices for proving their authenticity.

These were his words:

“The idea behind [the experiment] is that IoT has a promise of assigning a unique, non forgeable identity to physical items and what the blockchain provides is the way of managing and maintaining an identity.”

It is not the first time we read news related to the Isle of Man and its blockchain projects, as it is one of the most active governments in exploring the distributed ledger technology.

Network security and Proof-of-Work: do we need an alternative?

The Bitcoin protocol is designed using a proof of work mechanism, which determines who is permitted to sign the transactions that need to be verified.

A proof of work (PoW) is a piece of data which is computationally difficult to achieve, meaning that it required a lot of either time or hashing power (or both) to find the solution, but it’s easy to verify that this work was actually completed. Bitcoin uses a proof of work algorithm called hashcash, which has been around a lot longer than bitcoin itself, and was created with the purpose of being an anti denial-of-service (DOS) measure. Hashcash is fairly versatile and can be implemented with a number of functions; bitcoin uses hashcash-SHA256^2.

The proof of work consists in finding a target number that is below a certain target value, and in doing so the miner essentially “proves” that she performed a certain amount of “work” in trying various inputs. If I input a string into the SHA-256 hash function, there is no known way of determining what the output will be. Trial and error is the only way to find an input that will generate a hash that fits the desired criteria. In theory, you could nail it on the first try, but the probability of this happening is very small.

Given the current combined hashing power of the network, on average a solution is found every 10 minutes, at which point the block has been mined and the bitcoins are released as a reward. Every 2016 blocks, which ends up being approximately every two weeks, the algorithm moderates itself and either increases or decreases the difficulty of the problem. In practical terms, this means that it either increases or decreases the target value, so it’s easier or harder to find a value below it. This ensures a relatively smooth rate of release for newly mined bitcoins, and avoids flooding the market with coins at any given time.

It doesn’t matter whether I am using a supercomputer or a laptop to do the proof of work, it’s simply that with a supercomputer I can go through the attempts much faster, which means I have a higher chance of solving the problem before anyone else and therefore claiming the reward. The only thing that is important is how many hashes I can go through per unit of time, which is why the power of mining hardware is measured in MH/s, GH/s or TH/s (mega, giga and terahashes per second).

Some people in the cryptocurrency community have voiced the concern that miners may not be incentivized to continue mining if the price of bitcoin plummets, or simply because the reward for solving a given block decreases over time. Both are valid concerns but deserve to be addressed separately. In the first case, the assumption is that the reward amount would be too low for it to be worthwhile financially, and once all 21 million bitcoins have been mined this reward goes away entirely. Currently miners are primarily incentivized by the coinbase reward rather than the transaction fees, which is why many blocks end up with few transactions. Miners profit from the transaction fees, and the more transactions they include in a block, the more money they can make, but the opportunity cost of continuing to work on that block rather than go after a new one is high, as a competing block may win, rendering their work a waste of time and computing power.

Let’s assume that for whatever reason the price of bitcoin collapses, and therefore it is significantly less lucrative (net negative, once you factor in the cost of electricity) to mine. If miners are rational actors, most of them will stop mining, which is a problem for the network. The unintended consequence, however, is that mining would become dramatically less competitive, and therefore substantially more lucrative for those miners who continue to mine — at least in the short term. As I mentioned earlier, the algorithm self regulates to keep the average pace at which blocks are solved at around 10 minutes per block. As the bitcoin developer guide explains, Every 2,016 blocks, the network uses timestamps stored in each block header to calculate the number of seconds elapsed between generation of the first and last of those last 2,016 blocks. The ideal value is 1,209,600 seconds (two weeks).

Based on a comparison to the ideal value, the algorithm either increases or decreases the difficulty of the problem to solve, essentially recalibrating to try and get as close to 1,209,600 seconds as possible. To date, the difficulty has increased as more and more advanced ASIC miners continue to be developed, and more computing power is needed to have a chance at being the first to solve a block. However, the algorithm can also self-regulate in the opposite direction, making it easier to solve the problem by increasing the target value. Difficulty can be decreased by as much as 75%. This component of the protocol is particularly brilliant in design, as it basically guards itself against market shocks that could be produced by sudden swings in the mining power being inputted at any given moment.

Even if the bitcoins they are mining are worth substantially less post crash, if the miners believe that the expected future value of their bitcoins is significantly greater than it is at present, then it would make sense to continue mining. Alternatively, if a large percentage of miners quit because they didn’t anticipate the future value of bitcoin to make their present expenditure worthwhile, the new environment could still attract a new class of miners who are not currently mining because they don’t have the hashing power needed to make it lucrative, but if competition decreased dramatically, it would be. Presumably at this point other miners who had been mining previously would also see this and start getting back into the game, which would ultimately increase competition and start driving things in an upward direction again.

The likelihood that we see a huge drop in the price of bitcoin also decreases substantially over time, as it becomes less probable as the network expands. One of the main reasons bitcoin prices have been fairly volatile to date is that the network (by which I mean the number of consumers with wallets and merchants who accept bitcoin as a form of payment) is still relatively small. Bitcoin’s market cap has been hovering between 7 and 10 billion dollars, which means that any hedge fund worth its salt could take a position and dramatically swing the market. Bridgewater Associates, for instance, is the world’s largest hedge fund with $150 billion in global investments under management. In theory, they could buy ALL the bitcoins that have been mined to date 19x over, and still have enough left to throw in six Instagram acquisitions in for fun. And that’s only one of the top funds. Because the market cap is small, bitcoin to date has been subject to the whims of large actors; as the cap increases, there’s a strong chance that this will change.

There’s also the issue to consider that even in the absence of a price crash, incentives to mine naturally decrease over time as the amount of bitcoin received as a reward for mining a block is halved every 210,000 blocks, or approximately every four years. Theres is reasonable cause for concern that without the incentives provided by block rewards the network will no longer be secured, in that the transaction fees will not be sufficient to support the cost of securing the network. This is a manifestation of the game theory concept of the “Tragedy of the Commons” in which no individual actor wants to perform work or contribute to the community because he believes that she can reap the benefits regardless, but when everyone behaves this way, the system ends up collapsing and leaves everyone worse off. No one wants to pay transaction fees, but if everyone avoids paying them, the miners will have no incentive to keep security levels high, which could result in a systemic collapse.

To some extent, the point in time at which this problem becomes a reality will depend on the price of bitcoin, and no one can accurately predict when the network will reach that point, but even if prices continue to grow this is likely only a case of delaying the inevitable. If a bitcoin today is worth $600 and I receive 25 when mining a block, and in ten years I only receive 6.25 bitcoins for doing the same work, yet each one is worth $100,000, mining still makes a lot of sense. Even considering the investment in mining equipment, assuming that the amount of electricity I will have to expend will be higher, and discounting for 2-3% annual inflation, there’s still a substantial potential upside. There are a number of external factors (exact cost of electricity, price of ASICs or other mining equipment, etc) that will play into this and influence whether the network incentives to mine remain high enough, so it is worthwhile considering other mechanisms, prominent amongst which is proof of stake.

Proof of stake (PoS) is an idea that came about as an alternative solution to proof of work, primarily as a safeguard to some of the original protocol’s perceived shortcomings. Apparently it was first proposed in 2011 in the bitcoin talk forum by “QuantumMechanic”, and since then several models for implementation have been developed. A proof of stake scheme is similar to proof of work in that it is also a mechanism for determining who will sign the transactions in a given block, but instead of relying on hashing power, it uses ownership as the deciding factor. Simply put, if Alice holds 5% of all coins, she has the ability to mine 5% of the blocks. Theoretically this should increase network security by making it more difficult to mount a 51% attack. In order to do so, someone (probably a mining pool) would have to control over half of all coins in existence, which is much harder to do than controlling 51% of the hashing power. It’s worth considering that this isn’t impossible, as a large centralized pool could form and come to control over half the coins in circulation through a combination of owned coins and loans, for example. Realistically, however, in a proof of stake situation it wouldn’t make much economic sense to mount this type of attack. It would substantially reduce confidence in the network’s security, and likely cause the price to plummet. By crashing the value of a coin in which it is so heavily invested, the malicious mining pool would essentially be shooting itself in the foot. To some degree this is also true in a PoW scenario, but the disincentive is much stronger where PoS is being applied.

Although there’s no way to know exactly if and when an alternative to proof of work will become necessary due to a lack of mining incentives, a proof of stake scheme could also be a desirable solution for environmental and efficiency reasons. Since the proof of work process does not actually solve real-world problems, the energy is essentially burned without a real return, which is suboptimal. Implementing PoS, either in the form of a fork from the main proof of work blockchain or via the use of an altcoin that uses it (ie Peercoin, or something similar) could be significantly less costly than bitcoin mining as it currently stands, because the current system gobbles up a huge amount of electricity. Because PoS uses far less energy, as almost none is expended in the mining process, it would be substantially cheaper to make a profit mining than in a PoW scenario. It would also meaningfully reduce transaction fees in the long run, as miners wouldn’t have to charge high fees in order to cover their power and hardware costs.

We still lack a perfect solution to all these issues, and PoS is not a panacea either. One problem I see with implementing a PoS mechanism is that it could cause illiquidity in the market and lead to great concentrations of wealth. Miners would be incentivized to hold their bitcoin in order to be allowed to mine more, and therefore large concentrations pools of currency would accumulate. Currently, miners have an incentive to convert some of their mined bitcoins into dollars by selling them, but this is largely true because of a) price volatility – it is still risky to hold everything in bitcoin and b) there are still many assets that cannot be purchased using bitcoin. If PoS were implemented, and as both a) and b) become less relevant as the network expands, this could lead to a vast majority of coins being held by very few.

Despite the considerable improvements that proof of stake offers over proof of work in certain spheres, ultimately neither proof of work nor proof of stake offer a perfect solution to long-term network security concerns. Still, both clearly have useful characteristics which, applied in conjunction, could help overcome some of their own shortcomings. Just as I was wrapping up this writeup, Ryan Selkis passed along a fascinating paper by Bentov, Lee, Mizrahi, and Rosenfeld which proposes a third option, called Proof of Activity (PoA). PoA is predicated on the belief that neither PoS nor PoW are flawless, and seeks to pull in some of the better aspects of both. Given that this piece has already gotten quite lengthy in just looking at proof of work and proof of stake, I’ll write about the PoA paper separately sometime soon. The paper, titled “Proof of Activity: Extending Bitcoin’s Proof of Work via Proof of Stake”, is fairly technical, but it’s very thorough and for those who are so inclined I definitely recommend a read.

Staking PPC: Staking Peercoin on HolyTransaction Wallet

Staking Coins: Staking Peercoin

Bitcoin and many other early cryptocurrencies use a consensus model known as proof of work. This requires powerful computers to perform cryptographic problems that verify transactions on a blockchain. Peercoin originated an alternative to this that is used in many cryptocurrencies.

Proof of Stake Originator

Peercoin introduced the concept of proof of stake, an alternative to the proof of work consensus model. In its initial stages, proof of work played a large part in the consensus model since it was a fork of Bitcoin. But the original proof of work-dominated model has almost fully given way to proof of stake. This is more environmentally friendly, removes the need for purchasing expensive mining equipment and allows transactions to be performed a lot more quickly than on proof of work blockchains.

Stake Peercoin on HolyTransaction Wallet

HolyTransaction Wallet is excited to present to you the launch of our new staking service. You can now leverage Proof of Stake (POS) holdings to safeguard crypto networks while earning financial rewards. Staking PPC has become much easier with HolyTransaction!

How Does Coin Staking in Peercoin Work?

This act of generating a new block is called minting, however staking is a more popular term today. In Peercoin’s implementation of proof of stake, each node tries to find a new block each second. If the block is valid and backed by sufficient coinage (coins*days), it is accepted by the network. Nodes are only eligible to find new blocks when their coins have been in a wallet for 30 days. Their odds of finding valid blocks go up with the age of the coin until it reaches 90 days, at which point the probability is maxed out. Once a node finds a new block, new PPC are then minted and, for each new block, that node gets a block minting reward. After a new block has been minted, the age of the coins in the node’s address that are involved in the minting is reset. The address will then not be eligible to be chosen based on those particular coins until 30 days have passed. Staking your Peercoin assets does lock them up from being spent or moved. However, you can sell or spend the PPC at any time—you will just lose the opportunity to mint new blocks.

Advantages of Staking Coins with Peercoin

Why stake Peercoin and not other cryptocurrencies? The return on staking is lower with Peercoin than with most other proof of stake cryptocurrencies. Vast majority of economic studies shows that ideal inflation is 2-3%. However, Peercoin is serious about keeping inflation low, currently at 3.33%. Peercoin’s reliance on proof of stake means that it should not suffer from the same scalability problems that have plagued proof of work platforms like Bitcoin. This means quicker transaction times and an overall better experience for retail and vending applications—which means great potential for the coin’s success in the future. You can learn more about its ecosystem in the Peercoin Primer video series.

Conclusion

Peercoin was the originator of proof of stake in its whitepaper, even though it took some time for proof of stake to actually make its way into widespread use on the blockchain. Staking Peercoin and its minting process presents a great opportunity to earn coin that will, in turn, earn you more coin. All you need is just to deposit PPC to start staking on your HolyTransaction wallet.

Bitcoin vs. Litecoin: What makes them different?

When it comes to cryptocurrencies, one name stands out from the rest: Bitcoin. Bitcoin is the gold standard upon which all the other cryptocurrencies, cumulatively known as altcoins, are evaluated. And that’s rightly so because Bitcoin is the most popular, the biggest in terms of market capitalization and so far, the one most likely to break into mainstream use. But among the contenders for the throne, one cryptocurrency that closely resembles Bitcoin and the earliest altcoin is Litecoin. It was created primarily to be a “lighter” version of Bitcoin. In fact, many people refer to it as ‘silver’ to Bitcoin’s ‘gold’.

Why is that the case? An attempt to answer brings us to the issue of Bitcoin vs. Litecoin, exactly what we are trying to explore here. Let’s point out the similarities as well as explain the differences between these two cryptocurrencies.

A brief history

Bitcoin was created by Satoshi Nakamoto who released the Bitcoin whitepaper in 2008, before Bitcoin Core was launched on 3rd January 2009. On the other hand, Litecoin was created by Charles Lee and released on October 7th, 2011.

Price and Market capitalization

Whereas Bitcoin and Litecoin share a lot in terms of their blockchain protocols, the same cannot be said about their prices and market valuation. We could say both are dependent on the market trends and user flexibilities, but the variation isn’t even close. Today, bitcoin commands the largest market share, dominating by 42% of the total market capitalization to stand at $163 billion. BTC trades at $9636 against the USD and was at its all-time high of $19,535 on Dec 17, 2017. Bitcoin has a current circulating supply of 16,914,275 BTC against a maximum supply of 21 million coins.

Litecoin, on the other hand, is ranked 5th on coinmarketcap.com with a market cap of $10.4 billion. Its price today is $187, though it climbed to an all-time high of $366 on 19 December 2017 when its market cap was also just shy of $20 billion. Incidentally, Litecoin on that day had a daily volume of an incredible $2.3 billion. The circulating supply of LTC is currently 55, 592,093 LTC with a maximum supply of 84 million LTC.

When compared in terms of Market capitalization and price valuation, Bitcoin is 10x bigger or more than Litecoin. The same applies to popularity and use. While they both function as a store of value and can be used to make payments for goods and services, Bitcoin is accepted by far more companies and individuals than Litecoin.

Coin supply and transaction speed

Bitcoin and Litecoin differ in terms of the maximum coin supply. While Bitcoin’s total supply is capped at 21 million coins, Litecoin will have a total of 84 million coins. Though they differ in this aspect, both coins are deflationary, and their coin trajectory may appear similar. Another similarity is that both coins are divisible into smaller parts that enable micro-payments for goods and services. The smallest Bitcoin part is called a “Satoshi”.

But the two coins do differ in relation to the amount of time it takes to generate a new block. Litecoin block generation is halved after every 840,000 blocks, which is four times more than bitcoin at 210,000 blocks. For Bitcoin, a new block is generated after approximately 10 minutes. However, Litecoin miners use about two and half minutes to generate a new block. This results in the variation of transaction speeds between the two coins.

Due to having a faster block time, Litecoin’s network is normally able to confirm transactions much faster than Bitcoin. For instance, it would take 10 minutes to confirm four transactions on the Litecoin network, whereas the same amount of time would be just enough to verify one block of transactions on the Bitcoin network. Bitcoin has been implementing changes to its protocol to scale better and increase transaction speed.

It is expected that Lightning Network will make Bitcoin faster. However, Litecoin will look to implement the same protocol as it often times, does with every Bitcoin update.

Mining algorithms

Mining is a very vital component of cryptocurrency, precisely those that use the proof of work mining consensus mechanism. What we said earlier about block generation essentially amounts to the concept of mining. Basically, mining refers to the addition of new blocks to the main chain on the network to form a “blockchain”. Cryptocurrencies utilize different cryptographic algorithms to secure transactions on the blockchain. Bitcoin uses the SHA-256 algorithm that allows for the use of ASICs (Application Specific Integrated Circuits) for mining.

This hardware equipment came to replace the GPU and FPGA miners. Bitcoin mining is a complex activity but can be summarized as the solving of computational math problems to verify and secure a new block to the blockchain. Bitcoin miners (nodes) get rewarded 12.5 Bitcoins for every new block. One criticism leveled at bitcoin mining is that the process consumes a lot of energy resulting in massive electricity bills.

Mining is also an important aspect of Litecoin. Scrypt is the mining algorithm used on the Litecoin network. The Scrypt algorithm is designed to be resistant to customized ASIC miners due to its memory-hard nature. This makes mining Litecoin a lot easier as you can do it using a CPU or GPU. however, there are concerns that Litecoin’s CPU/GPU mining days may be soon over as ASIC miners targeting the Scrypt algorithm have been developed by companies like Zeus and Flower Technology. While miners on the Bitcoin platform get rewarded 12.5 BTC for every new block, Litecoin miners get 25 LTC for every new block validly added to the blockchain. It should be noted that mining Litecoin is relatively cheaper than bitcoin, but Bitcoin could be more profitable for those with the right equipment.

Conclusion

Bitcoin and Litecoin share a lot in common when it comes to the functional aspect of being stores of value. However, Bitcoin beats Litecoin on numerous fronts, specifically on price valuation and market adoption. Naturally, bitcoin would be an attractive coin for investment, but if you are looking for an affordable crypto with the potential to grow then Litecoin could be it.

Intesa Sanpaolo Blockchain: a new trial for recordkeeping

The newest Italian Banca Intesa Sanpaolo blockchain – related project has been tested with the main goal of validating trading data.

Thanks also to a partnership with Deloitte and the Italian startup Eternity Wall, Intesa San Paolo started to test a new proof-of-concept at the end of 2016.

Heart of the project is the open-source OpenTimestamps protocol, developed by Peter Todd, a Bitcoin Core contributor, that Eternity Wall moved to implement.

The Intesa Sanpaolo blockchain project uses the bitcoin distributed ledger to notarize transactions and create a publicly available database trail for future referral.

Information security officer for the bank, Carlo Brezigia explained:

“Relevant data has been hashed to produce a short unique identifier – a digest – equivalent to its digital fingerprint. This fingerprint has been associated to a blockchain transaction and hence registered on the blockchain: the blockchain immutability provides robust non-refutable timestamping that will always prove without any doubt the existence of that data in that specific status at that precise moment in time.”

According to a Deloitte statement, Intesa Sanpaolo tested this tool between October and February with tht idea of including support for other blockchains, potentially including also private ledgers.

This Italian blockchain trial shows the will of regulated financial institutions to test public blockchains.

In an official announcement, the bank’s retail innovation accelerator officer, Gianni Cavallina, explained the interest in experimenting these protocols beyond the main use case of digital currenciese:

“In particular, considering public blockchains, we are exploring the applicability of different use cases, abstracting from the value of its native digital currency. Notarization is one of the most interesting applications.”

Intesa Sanpaolo Blockchain projects– also member of the R3 distributed ledger consortium – also include tests on several blockchain use cases made during the previous years, including trade finance and digital identity.

WebJet Blockchain project for travel bookings

Microsoft is working on the newest Webjet Blockchain project to allow users booking travels through the distributed ledger.

Microsoft, in fact, is testing a blockchain proof-of-concept developed together with the Australian travel agency called Webjet for a pilot that will be ready during this year.

During a speech given at the CoinDesk’s annual conference titled Construct 2017, Cale Teeter and Eric Maino, or Microsoft senior software development engineer and technical architect, commented that they think that the project, which looking for make travel bookings easier by using a blockchain-based system, will reach its development status during the next few months.

“Webjet wanted to see, instead of everyone running their own proprietary systems, a system that connects companies they own. They’ve been running their real data through it and they’ve been finding interest discrepancies in the business, and they’re hoping to expand it out,” said Maino.

Revealed in November, the Webjet managing director John Guscic explained that the online booking system has become apt to be developed thanks to the several systems used for its business projects including the hotel room wholesaling.

“Between five and 10% of bookings can be impacted or, in other words, up to $10bn-worth of transactions,” Guscic explained in a previous statement.

Microsoft is not new to blockchain-based project. Earlier this year, in fact, the computer well-known company revealed its project called Manifest for tracking products worldwide. Read more by clicking here.

The newest Deutsche Börse Blockchain project

A new Deutsche Börse blockchain project was unveiled today as the market operator revealed a new blockchain proof-of-concept to manage bank cash transfers.

The so-called ‘CollCo’ (or, ‘collateralized coin’), is the new Deutsche Börse blockchain project created together with Eurex Clearing, or the clearing house used by the Deutsche Börse.

Using the same code of the Hyperledger Fabric project as a basis, the company wants to obtain a patent approval for this revolutionary transfer solution available thanks to the distributed ledger.

According to the official press release shared by the Deutsche Börse, the next step is to work with customers, regulatory and central banking contacts.

This is the official description for CollCo:

“All peer-to-peer payments based on tokenised commercial bank money are accompanied by movements of collateral between the respective Eurex Clearing members using the [central counter party’s] functionality and rules.”

The press release continues by saying that the idea links together “existing and potential new use cases” as the “handling of margining requirements, credit risk free payments, and delivery-versus-payment asset/value transfer on the blockchain”.

The Deutsche Börse has spent much time during the past year testing several blockchain use cases, including one thanks to a partnership with Germany’s central bank.

Also, in February 2016, the company partecipated at the New York blockchain startup Digital Asset Holding’s $60m funding round.

During a speech given last week, CEO Carsten Kengeter talked about the so-dubbed “Exchange 4.0” powered by next-generation technologies.

“Exchange 4.0 will use blockchain intelligently. Exchange 4.0 will convert data into investment tools. Finally, Exchange 4.0 will be as varied – and perhaps also as easy to use – as an app store,” he explained.
