智能合约是加密的基本组成部分，尤其是在去中心化金融 (DeFi) 领域。 它解决了加密世界难题，因为它们是去信任的、自主的、去中心化的、防篡改的和透明的。 对于那些不熟悉的人来说，智能合约是一段自动执行指令的代码。 然后这些指令在区块链上验证，并永远存在。
1994 年， 计算机科学家尼克·萨博 (Nick Szabo)，首次提出智能合约，早于加密货币； 然而，因为以太坊的出现得以普及。 顺便说下，Szabo 还负责在 1998 年将一种名为 Bit Gold的数字资产理论化，这是比特币的前身。 从那时起，其他流行的智能合约，如 Solana、EOS、Polkadot 和 Binance Smart Chain 已经成为以太坊的竞争对手，它们都有各自鲜明的特点。
Smart Bitcoin Cash, or SmartBCH, recently went live to provide “a decentralized, high-throughput, low-cost, and easy-to-use infrastructure for cryptocurrency” according to the SmartBCH白皮书，旨在为加密货币提供“去中心化、高吞吐量、低成本且易于使用的基础架构”。 相信 SmartBCH 将会在更短的时间内提供与 ETH 2.0 相同的好处。
To understand the reason for SmartBCH, let’s first understand the components of the Ethereum network and some issues associated with the blockchain.
目前用户在以太坊区块链参与各种去中心化应用程序 (dApp)会面临的一个主要问题是高 手续费，这让很多人望而却步。
以太坊的吞吐量较低，这意味着只有少量交易可以通过链上处理。 矿工会优先处理Gas费用高的交易，如果用户不愿意支付更高的gas费用，他们必须等待很长时间，就会有用户 反应 ，他们的交易请求延迟很久没有被处理，甚至很多天。
The process in which miners prioritize the blocks with the highest gas fees to earn an extra profit is known as front-running. With such high fees, it only makes financial sense for wealthy individuals or institutions to participate in DeFi activity at scale, which shifts the dynamic of the Ethereum network to a more “whale” dominated ecosystem. When you use a decentralized exchange (DEX), it’s common to see gas fees between $200-300. This process goes against the ideological foundations of crypto, which was designed to be decentralized with low barriers to entry.
SmartBCH 尝试从两个方面解决这个交易成本高的问题。 首先是利用 SmartBCH 区块链上极高的吞吐量，使大量数据可以快速通过交易，减少交易时间。
SmartBCH aims to reduce transaction fees by reordering the transactions in a “pseudorandom” way to make the prioritizing process more complex. The aim here is to prevent the validators from front-running blocks.
Another factor that increases gas fees is that executing smart contracts costs more in gas fees from storage costs than computation power. The SmartBCH whitepaper blames MPT, which is Ethereum’s storage engine. SmartBCH aims to develop “MoeingADS” to replace MPT, which is meant to be faster, resulting in cheaper fees.
One important aspect of sending transactions on the Ethereum blockchain is the off-chain “Queries per Second,” or QPS. QPS inquires the blockchain about its condition and transaction history to confirm all the information is running smoothly and correctly. These inquiries happen multiple times rather than a transaction, which only occurs once. QPS, however, requires developers to become full nodes, which is very expensive.
SmartBCH’s whitepaper argues its development of “MoeingDB” will have a high QPS Web3 API, which essentially means it will deliver the best performance for the blockchain’s workload. This would also be open source and hopefully, make the Web3 API market more decentralized. This would also benefit Ethereum and potentially further reduce the need to rely on third-party private companies such as Infura to expand the blockchain.
目前的以太坊区块链是单链，允许智能合约之间的零延迟和原子互操作性，因为它们在同一条链上。以太坊 2.0 将尝试通过添加分片来解决可扩展性问题。
While this would reduce the backlog of transactions, it would negatively impact latency and interoperation, taking away from the benefits of the single-chain experience. While SmartBCH will also have parallel chains, MoeingEVM is designed to address the issues of multiple chains and maximize transaction parallelism through a process called “enforced-bundle parallelism.”
Now that we understand the types of issues associated with the current Ethereum blockchain and potential problems on the Ethereum 2.0 blockchain and the ways the SmartBCH developers plan to solve these issues, let’s break down the additional components of SmartBCH that make it an attractive alternative.
SmartBCH will be EVM compatible, meaning it is compatible with the Ethereum blockchain so that Ethereum apps can run on the SmartBCH blockchain. This will allow Ethereum users to participate in the same protocols or dApps; however, instead of spending hundreds of dollars on transaction fees, they will only need to pay cents – a fraction of the cost.
SmartBCH tokens are called “Smart Evolution Proposals,” or SEP20 for short. The native token for SmartBCH is unsurprisingly Bitcoin Cash, or, BCH, which is also used to pay for the gas fees. Although SmartBCH BCH is an SEP20 token, it is simply referred to as BCH. There will, however, be a gateway to transfer BCH to the SmartBCH Chain as a gas token.
这与以太坊不同，因为 ETH 不是 ERC20 代币。 网络上收取的 gas 费用将被分配，以使 BCH 更具通缩性：一半将销毁，另一半将奖励给验证者。
CoinFLEX is aiming for flexUSD to be the first stablecoin on SmartBCH. First mover advantage is extremely important for mass adoption in crypto. If flexUSD becomes the best stablecoin to use on SmartBCH, a positive feedback loop would require other users to buy flexUSD. This means they won’t need to buy USDC or any other stablecoins.
工作量证明 (POW) 和权益证明 (POS) 结合
SmartBCH uses the speed and efficiency of PoS technology to improve speed in voting while basing the voting power off of PoW. The hash power for voting on SmartBCH also uses the dSHA256 network, which CoinFLEX argues is the “most powerful and decentralized computer network in the world.” This combines the DeFi ecosystem of Ethereum, which can be used on a powerful, decentralized, and cheap blockchain network.
While SmartBCH has outlined potential solid solutions to solving issues on the Ethereum network, as well as unique features that differentiate the blockchain from other Ethereum competitors, it’s still in its infancy. Only time will tell as crypto pioneers attempt to expand the world of DeFi to different smart chains.
