How to Scale Bitcoin or What is the Lightning Network?

scaling bitcoin

Blockchain is an absolutely revolutionary technology that can change almost all branches of human activity. But it has one rather serious problem that prevents it from “conquering the world” – this is speed. Unfortunately, now the problem of scalability does not allow using this technology, so to speak, at full capacity. As the more participants of the network there are, the slower speed of its work will be. There are several options for solving this problem; we will talk about one of them today. So, the technology of the Lightning Network: what is it and how will it help Bitcoin and other coins to become more nimble?

1. History and operation principle of technology

Thoughts about creating a solution to increase the speed of the Bitcoin network began to appear almost immediately after its creation. The first brick in the foundation of Lightning Network technology was the idea of ​​creating payment channels between the two users. The payment channel is a kind of autonomous corridor between two bitcoin-wallets, transactions in which can occur without the participation of the entire network. Such a solution will resolve several issues at once:

  • transactions within the channels are almost instantaneous, as they pass directly, without the participation of the whole blockchain;
  • commission fee for such transactions is not charged, since it does not require processing by miners.

How do the payment channels work?

Channels work as deposit cells, in which two users must firstly put equal shares. Only the fact of opening the channel is recorded in the blockchain, everything that happens inside next remains anonymous for all other network members. Means that are stored in it cannot be spent by one participant, for this, the mandatory permission of the second user is required. These coins can only be used for transferring to each other.

Suppose user A and B have placed 5 BTC in the trade channel, then user A expresses the desire to send 3 BTC to the user B, do you think what is necessary to do for this? He just needs to transfer ownership of the required amount to user B.

A similar concept had been introduced back in 2009, but only in 2018 such ideas were implemented in a more or less working tool called Lightning Network.

2. What is the Lightning Network?

Without consolidation in network, the channels themselves cannot become a comprehensive solution to the problem of blockchain’s scalability. In order to describe the work of the Lightning Network, it is necessary to take three users A, B, C at once. Trading channels are open between A and B, and also between B and C. Let user C want to transfer to user A a certain number of coins (there is no channel between them) . In this case, he asks the user B to write out the receipt to user A, and then he carries out the transaction in favor of B via their channel.

This is a fairly simplified illustration of the operation of the Lightning Network; it can carry many levels, which will significantly reduce the load of the blockchain.

3. Main purpose and scenarios of application

This technology has recently gained popularity, as the scope of its application is quite extensive:

  • increasing the bandwidth of popular cryptocurrencies (now the technology works only with BTC, but in the future it can appear in ETH, LTC, etc.);
  • a significant increase in the speed of work of cryptocurrency exchanges, which would allow traders to make instant transactions;
  • instant payments within applications, games, etc.

4. Conclusion

The technology of the Lightning Network has great prospects, in the foreseeable future it can become the main one in the industry. It allows you to substantially unload the blockchain network and increase the speed of transactions. In the last few months, this technology is rapidly gaining a new audience.

Bitcoin Cash: Overview, Advantages and Disadvantages, Details of The Hard Forks

In this article we will talk about the most famous bitcoin`s hard fork – the Bitcoin Cash: it`s advantages and disadvantages, forecast for the future, as well as the hard fork, which will happen on November 15, 2018.

  3. Briefly about the hard fork Bitcoin Cash
  4. Conclusion

1. Briefly about Bitcoin Cash and comparison with Bitcoin

The main popularizer of the “new” coin is Roger Ver. He is quite famous person in crypto world. He was one of the first cryptocurrency investors. Due to increased attention to this industry, he became known as Bitcoin Jesus. But later, Ver decided to actively promote the hard fork (a branch) of the first cryptocurrency – the Bitcoin Cash. The network split occurred on August 1, 2017.

What is the difference between the BTC and the BCH?

  • Increasing of transaction`s speed in several times. The main feature of the new coin is an increased block`s size to 8 MB. On May 15, 2018, developers released the update, after which the block`s size increased to 32 MB. This solution made it possible to record much more transactions in one block, and thereby to increase network bandwidth.
  • Low commissions. Bitcoin Cash has very small commissions $0,05 – $0,010, which is significantly lower than that of the “older brother” $8 – $15.
  • With the current network load, a queue of unconfirmed transactions does not exceed 200 – 250, whereas with the original Bitcoin, this number can reach 7,000 – 10,000.

2. Disadvantages of Bitcoin Cash

Significant disadvantage of this fork is the automatic adjustment of the network`s computing complexity. Unfortunately, it has direct dependence on the speed of extraction of new data. That is, if for a certain amount of time miners get an insufficient number of blocks, then complexity decreases. This pattern works in both directions.

Miners started to use this vulnerability and got BCH in periods of complexity recession, and when the situation changed, they turned to BTC. Such actions led to the network`s destabilization and increased volatility of the BCH rate. This problem has not been solved till this day, but the development team manages to restrain it.

Cryptocurrency investors do not consider Bitcoin Cash as a long-term asset yet. This coin is more used as a speculative tool. For this reason, at the moment BCH has rather vague and uncertain future.

3. Briefly about the hard fork Bitcoin Cash

The hard fork of Bitcoin Cash was on November 15, 2018. After this event, the network received two incompatible consensus protocols BCHABC и BCHSV. The community of coin divided into two parts: on the one hand Roger Ver, and on the other Craig Wright. The outbreak of the conflict is considered to be Bitcoin ABC update, which began to support smart contracts and atomic swaps. In response to this update, Craig Wright offered the community his vision for the future development of the project. He proposed to increase the block`s size up to 128 MB. Such decision was not supported by Roger Ver and his part of miners. Because of this, another coin will now appear in the cryptocurrency world.

This is very good news for BCH holders. The matter is that after hard fork, investors received the same amount of coins of the new network, which complies with their BCH`s balance.

Against this background, the Bitcoin Cash rate grew up by almost 50% only for the first week of November.

This growth was artificial, therefore, we observed the same rapid rollback before the hard fork.

4. Conclusion

Bitcoin Cash is a project with rather big ambitions, ultimate goal of which is to push the original Bitcoin from the first place. In fact, BCH has fewer problems with scaling, and also can boast of low transaction commissions. But on the other hand, there is conflict between developers, still unsolved problem of automatic control of complexity, as well as increased volatility. Now it is hard to make long-term forecasts for Bitcoin Cash, as it is not clear yet, which of two networks will be more stable.

Three Hellish Days for Cryptocurrency: Reasons of The Fall of The Currency and What To Do Next?

The current condition of the cryptocurrency market raises a number of question from traders. For the third day, the industry is either trying to revive Bitcoin and other cryptocurrencies, or just watching the collapse of the course.

The question of what caused the collapse of the market and what should do those who still have cryptocurrency  – makes world crazy. That is why, The Coin Shark have found answers for all of these questions and analysed per minute history of the fall of currency of Bitcoin.

The Chronology of the fall from 14th to 16th November

Wednesday, November,14 , Bitcoin break another 2018 bottom.  According to data of CoinMarketCap, at 11:34 UTC the rate of the first cryptocurrency behaved stably, being at $6 365.

Nothing foretold troubles, but at 17:19 UTC began unexpected fall, which last till the 19:19 UTC, where the price of BTC remained in half-dead condition at $5 765. Therefore, the capitalisation of the marked fell to $102 billion.

After that, Bitcoin started to resist. In 20:04 UTC the currency show vital signs, increased to $5 858. But still, the end of 14th November was not a happy ending. In 22:48 UTC was settled a new record – $5 568.

If compare the data with an individual market, then on a Bitstamp the price of the BTC has already dropped to $5 534, and on the Kraken – $5 510. Last two weeks, Bitfinex exchange trade Bitcoin more than $6 000 per each unit.

It turned out, that the 14th of November was still far from the end of BTC fall. According to CoinMarketCap, Thursday, November, 15, at 17:04 UTC, Bitcoin shocked everybody with the course of $5 358. On Bitstamp the first cryptocurrency down to $5 446, and on the Bitfinex – $5 638. At this point, this is the lowest course from the end of October, 2017.

The condition of the cryptocurrency market for the last year is unstable. It is accompanied by unexpectable highs, as well as painful falls. But not only Bitcoin drop it’s price position on 14th of November. Together with it, into a deep red zone came the major part of other cryptocurrencies. In doing so, the total capitalisation fell by $190 billion.

At the writing of this article, 16th of November, the condition of the cryptocurrency market is still in critical position – the course of Bitcoin stood at $5 500, and Ethereum backed down the second place in capitalisation Ripple.

What caused the collapse?

Just think about it, less than 24 hours ago, it was possible to sell the BTC on a thousand dollar higher. Probably, it is impossible to define why “the foundation was cracked” under the cryptocurrency, as for the example it can be done in a regular market. In the digital, the effect is first  seen and only than the reason becomes known.

Reason #1: Contagious effect

On the basis of past, the cause of the fall have psychological nature.
For example, people are massively starting to buy cryptocurrencies or fanatically selling.

Reason #2 : Direct correlation

Each financial currency  pegged to its government, as for the example dollar – to the US economy. Cryptocurrency pegged with the people, which are both buying or selling it.

Reason #3: Global Bitcoin influence

Ironically, but there is a theory, that the general condition of the cryptocurrency is affected by Bitcoin. The value of all digital market is estimated in $182 billion, the $90 billion of which belongs to BTC. The majority of cryptocurrencies  should be transferred especially in Bitcoin, before the sale.
And now imagine, that selling of Bitcoin will start simultaneously several major players of the market. After this, the BTC prices are lowering, and this cause  the panic attacks more than ones: “ Buy everything and as quickly as possible, while the price is low!” – this makes the course to grow.

What should do the owners of cryptocurrency: sell or wait?

It depends on the inner aspects of each owner. Even when the course is rising – it still have cycles of fall.

Who and how will affect the collapse of rate?  

Cryptocurrency is the unstable tool. It’s system decentralised and doesn’t have the management center. Digital currency should strengthen the positions, so it can give the accurate forecast for the future. But, it appeared, that this fall will have no affect on ordinary users.

There is no denying, that in a consequence many crypto-business will close. Cryptocurrency exchange are in the minimum risk area, as in such cases the number of transaction increases.

Most of all, miners and the owners of the mining field will suffer the most. Since, the profitability depends on the price of extracted cryptocurrency. Within recent events, it is clear that mining is unprofitable occupation.

Crypto Wars: Jihan Wu vs Craig Wright, Who Gets McAfee’s Support?

The infamous hard fork of Bitcoin Cash has created some tension between the major crypto personalities in the industry. It is especially the case with the supporters of the two different BCH protocols.

One of the main “fights” has started between the CEO of Bitmain Jihan Wu and a computer scientist Craig Wright, who have repeatedly gone at each other on the social media, claiming that their vision of Bitcoin’s future is correct. Later on, the “war” was joined by John McAfee who supported Jihan Wu.

Craig Wright did not take long to respond.

Hopefully, the conflict will be settled peacefully, because the crypto industry needs all of the abovementioned people to function properly and develop.
