Чем отличаются биткоин (BTC) и Bitcoin Cash (BCH)

В августе 2017 года блокчейн биткоина разделился на два отдельных блокчейна, в результате чего появилась новая цифровая валюта, названная Bitcoin Cash. Этому предшествовала ожесточённая дискуссия о том, как решить проблему масштабируемости биткоина.

В этой статье вы узнаете, чем отличается биткоин (BTC) от Bitcoin Cash (BCH).

Биткоин

В 2009 году , после выпуска своего white paper , описывающего создание децентрализованной цифровой p 2 p — системы, биткоин стал первой в мире криптовалютой. На сегодняшний день биткоин является общепризнанной альтернативной валютой с рыночной капитализацией свыше $ 50 млрд. и ценой одной монеты, давно превзошедшей стоимость тройской унции золота. Сейчас биткоин используют в качестве валюты для онлайн — расчетов, хранилища средств или новой альтернативной инвестиции.

Однако с ростом интереса к биткоину нагрузка на его сеть колоссально увеличилась, что привело к замедлению транзакций и повышению комиссионных сборов для пользователей. Стало очевидно, что биткоину для дальнейшего развития потребуется модернизаци я .

Обновление SegWit ( Segregated Witness )

Было предложено несколько решений проблемы масштабируемости, однако на их фоне выделяется технология Segregated Witness , или , коротко , SegWit. Это модернизация блокчейна, удаляющая некоторые данные для освобождения места в блоках, что позволяет осуществлять больше е количеств о транзакций за тот же промежуток времени. Оппоненты SegWit в свою очередь предлага ли увеличить размер блока.

В итоге было решено внедрить SegWit и впоследствии увеличить размер блоков , однако противникам SegWit этого оказалось недостаточно.

2 августа 2017 года был внедр ё н SegWit , и одновременно с этой модернизацией блокчейн разделился для создания альткоина B itcoin C ash, позволявшего генерировать блоки большего объ ё ма. Оригинальный биткоин за счёт SegWit получил возможность проводить большее количество транзакций , чем раньше.

Разница между биткоином и Bitcoin Cash

Ключевая разница между BTC и BCH заключается в размере блока. Размер блока биткоина ограничен 1 Мб , в то время как B itcoin C ash предлагает блок размером 8 Мб . Если блок биткоин а вмещает около 2500 транзакций , то уже для первых блоков BCH этот показатель достигал 7000 . Таким образом, перспективы Bitcoin Cash в плане масштабируемости на первый взгляд выгляд я т гораздо благополучнее.

Однако большинство инфраструктур биткоина (кошельки, плат ё жные сервисы и т.д.) не поддерживают Bitcoin Cash и считают его просто очередным альткоином, а не «новым биткоином». Это значит, что его использование пока ограничено спекуляциями на биржах .

Вс ё это наталкивает нас на вопрос о реальной ценности BCH. Если его не готовы использовать и принимать покупатели и продавцы, почему его стоимость должна расти? На данный момент Bitcoin Cash поддерживает лишь небольшая часть сообщества, которой нравится идея увеличения размер а блока. Остальные участники остались на стороне биткоин а и SegWit.

Если выбирать, куда вкладывать деньги, то биткоин до сих пор выглядит лучшим вариантом. Bitcoin Cash может в любой момент обвалиться и оказаться внизу таблицы крипто валют, став о ч ере д ным альткоином с малой реальной ценностью.

Bitcoin vs. Bitcoin Cash: What Is the Difference?

Nathan Reiff has been writing expert articles and news about financial topics such as investing and trading, cryptocurrency, ETFs, and alternative investments on Investopedia since 2016.

Bitcoin vs. Bitcoin Cash: An Overview

Since its inception, there have been questions surrounding bitcoin’s ability to scale effectively. Transactions involving the digital currency bitcoin are processed, verified, and stored within a digital ledger known as a blockchain. Blockchain is a revolutionary ledger-recording technology. It makes ledgers far more difficult to manipulate because the reality of what has transpired is verified by majority rule, not by an individual actor. Additionally, this network is decentralized; it exists on computers all over the world.

The problem with blockchain technology in the Bitcoin network is that it’s slow, especially in comparison to banks that deal with credit card transactions. Popular credit card company Visa, Inc. (V), for instance, processes close to 150 million transactions per day, averaging roughly 1,700 transactions per second. The company’s capability actually far surpasses that, at 65,000 transaction messages per second. 

How many transactions can the bitcoin network process per second? Seven.   Transactions can take several minutes or more to process. As the network of bitcoin users has grown, waiting times have become longer because there are more transactions to process without a change in the underlying technology that processes them.

Ongoing debates around bitcoin’s technology have been concerned with this central problem of scaling and increasing the speed of the transaction verification process. Developers and cryptocurrency miners have come up with two major solutions to this problem. The first involves making the amount of data that needs to be verified in each block smaller, thus creating transactions that are faster and cheaper, while the second requires making the blocks of data bigger, so that more information can be processed at one time. Bitcoin Cash (BCH) developed out of these solutions. Below, we’ll take a closer look at how bitcoin and BCH differ from one another.

Key Takeaways

• Bitcoin is limited by transaction processing time, an issue that has caused rifts between factions within the bitcoin mining and developing communities.
• Bitcoin Cash was started by bitcoin miners and developers concerned about the future of the bitcoin cryptocurrency, and its ability to scale effectively.
• While bitcoin blocks are limited to 1 MB, BCH blocks are up to 32 MB.

Bitcoin

In July 2017, mining pools and companies representing roughly 80 percent to 90 percent of bitcoin computing power voted to incorporate a technology known as a segregated witness, or Segwit   This fix makes the amount of data that needs to be verified in each block smaller by removing signature data from the block of data that needs to be processed in each transaction and having it attached in an extended block. Signature data has been estimated to account for up to 65 percent of data processed in each block, so this is not an insignificant technological shift.

Talk of doubling the size of blocks from 1 MB to 2 MB ramped up in 2017 and 2018, and, as of February 2019, the average block size of bitcoin increased to 1.305 MB, surpassing previous records. By January 2020, however, block size has declined back toward 1 MB on average.   The larger block size helps in terms of improving bitcoin’s scalability. In September 2017, research released by cryptocurrency exchange BitMex showed that SegWit implementation had helped increase the block size, amid a steady adoption rate for the technology.   Proposals to both implement Segwit and double the block size were known as Segwit2x.

Bitcoin Cash

Bitcoin Cash is a different story. Bitcoin Cash was started by bitcoin miners and developers equally concerned with the future of the cryptocurrency and its ability to scale effectively. However, these individuals had their reservations about the adoption of a segregated witness technology. They felt as though SegWit2x did not address the fundamental problem of scalability in a meaningful way, nor did it follow the roadmap initially outlined by Satoshi Nakamoto, the anonymous party that first proposed the blockchain technology behind cryptocurrency.

Furthermore, the process of introducing SegWit2x as the road forward was anything but transparent, and there were concerns that its introduction undermined the decentralization and democratization of the currency.

In August 2017, some miners and developers initiated what is known as a hard fork, effectively creating a new currency: BCH. BCH has its own blockchain and specifications, including one very important distinction from bitcoin. BCH has implemented an increased block size of 8 MB to accelerate the verification process, with an adjustable level of difficulty to ensure the chain’s survival and transaction verification speed, regardless of the number of miners supporting it.
In 2018, the maximum block size for BCH was increased 4x to 32MB, but actual block sizes on Bitcoin cash have remained only a small fraction of the 32MB limit.

Bitcoin Cash is thus able to process transactions more quickly than the Bitcoin network, meaning that wait times are shorter and transaction processing fees tend to be lower. The Bitcoin Cash network can handle many more transactions per second than the Bitcoin network can. However, with the faster transaction verification time comes downsides as well. One potential issue with the larger block size associated with BCH is that security could be compromised relative to the Bitcoin network. Similarly, bitcoin remains the most popular cryptocurrency in the world as well as the largest by market cap, so users of BCH may find that liquidity and real-world usability is lower than for bitcoin.

The debate about scalability, transaction processing, and blocks has continued beyond the fork which led to Bitcoin Cash. In November of 2018, for example, the Bitcoin Cash network experienced its own hard fork, resulting in the creation of yet another derivation of bitcoin called Bitcoin SV. Bitcoin SV was created in an effort to stay true to the original vision for bitcoin that Satoshi Nakamoto described in the bitcoin white paper while also making modifications to facilitate scalability and faster transaction speeds. The debate about the future of bitcoin appears to show no signs of being resolved.

Why Use Bitcoin Cash?

Send Money Anywhere In the World, Almost for Free

With Bitcoin Cash, you can send money to anyone, anywhere in the world, 24 hours a day, 365 days a year. Like the Internet itself, the network is always on. No transaction is too big or too small. And you never need anyone’s permission or approval.

Be Your Own Bank and Have Full Control Over Your Money

The seizing of capital from account holders (“bail-ins”) that occurred in Cyprus and nearly in Greece, demonstrated that bank deposits are only as safe as political leaders decide. Even under the best of conditions, banks can make mistakes, hold funds, freeze accounts, and otherwise prevent you from accessing your own money.

Banks can also decide to block your transactions, charge you fees, or close your account without warning. Bitcoin Cash gives you full, sovereign control over your funds, which you can access from anywhere in the world.

A Scarce Digital Currency with a Known, Fixed Supply

The Bitcoin Cash protocol ensures there will never be more than 21 million coins in existence. Governments constantly print money out of thin air, endlessly inflating the supply and devaluing everyone’s savings. Bitcoin Cash has a fixed supply and therefore represents sound money.

Increase Your Privacy and Operate Anonymously

Bitcoin Cash offers more privacy and anonymity than traditional payment systems like bank transfers and credit card payments, since it’s normally impossible to know who controls a Bitcoin address.

Bitcoin Cash offers various levels of privacy depending on how it is used. It’s important to educate yourself thoroughly before using BCH for privacy purposes.

Enjoy Exclusive Discounts

Many merchants offer discounts for paying in Bitcoin Cash, because it eliminates credit card fees and helps grow the adoption of this new payment system.

Storing and managing tokens on a blockchain provides greater transparency and integrity than traditional forms of asset accounting and trading. Bitcoin Cash supports token protocols that power a variety of projects, and it is easy to create your own token backed projects.

Support Freedom Worldwide

Bitcoin Cash is a permissionless, open network. It empowers you to engage with your fellow human beings without intrusion. It’s decentralized, voluntary, and non-aggressive. As usage grows, old power structures will erode while fresh ideas blossom. It may help usher in the greatest peaceful revolution the world has ever known.

Benefits for Merchants

The network fee for a typical Bitcoin Cash transaction is less than one penny. If you want to convert your BCH into fiat currency, such as US dollars, you can do that through merchant processors for a cost that is still much lower than credit card processing.

Unlike credit cards, there are never any automatic voids, refunds, chargebacks, or other unexpected fees. Fraud protection is built into the system with no cost to the merchant.

A growing number of patrons are choosing Bitcoin Cash as a preferred payment method. They favor merchants who offer this payment option and actively seek them out.

Free Marketing and Press

By accepting Bitcoin Cash, merchants can gain free listings in website and app directories, gaining even more customers. They can also take advantage of this new trend and generate press for their business.

The History of Bitcoin Cash

In October 2008, Satoshi Nakamoto published the famous whitepaper entitled “Bitcoin: A Peer to Peer Electronic Cash System”. In 2009, he released the first bitcoin software that powered the network, and it operated smoothly for several years with low fees, and fast, reliable transactions.

Unfortunately, from 2016 to 2017, Bitcoin became increasingly unreliable and expensive. This was because the community could not reach consensus on increasing the network capacity. Some of the developers did not understand and agree with Satoshi’s plan. Instead, they preferred Bitcoin become a settlement layer.

By 2017, Bitcoin dominance had plummeted from 95% to as low as 40% as a direct result of the usability problems. Fortunately, a large portion of the Bitcoin community, including developers, investors, users, and businesses, still believed in the original vision of Bitcoin — a low fee, peer to peer electronic cash system that could be used by all the people of the world.

On August 1st, 2017, we took the logical step of increasing the maximum block size, and Bitcoin Cash was born. Anyone who held Bitcoin at that time (block 478558) became an owner of Bitcoin Cash (BCH). The network now supports up to 32MB blocks with ongoing research to allow massive future increases.

Decentralized Development

With multiple independent teams of developers providing software implementations, the future is secure. Bitcoin Cash is resistant to political and social attacks on protocol development. No single group or project can control it. Multiple implementations also provides redundancy to ensure that the network retains 100% uptime.
