减法协议中的函数和资产

The author's source subtraction theory has brought us a great improvement in blockchain cognition. If the smart contract is to add bitcoin, then the inscription space is to subtract bitcoin, and sorting and consensus of transactions is a necessary homework for all blockchain. Therefore, the subtraction theory can be applied to all public chain inscription spaces, which naturally has the characteristics of cross-chain. When we start to think about the subtraction protocol, it brings us great design space and gives us an opportunity to rethink the shortcomings and security risks. For example, the text is actually plain text, but the readability is poor. The design of many inscriptions should follow this principle to let users know what they are doing from the protocol level. The second point we think is the paradigm of smart contracts. Smart contracts allow each blockchain application to have its own acre of land to define data and codes. User assets are data codes, which can manipulate data such as transfers, and for those commonly used contracts, such as the fact that the codes have gone through a long time and countless pairs of eyes. Verification However, there are thousands of assets in the blockchain, even though most of them follow the standards, but the standard implementation is not mandatory. In the early days, many contracts were directly scrapped because of major security issues. With the growth of engineers' experience, major security issues became less and less common, but it is still impossible for users to audit all smart contracts on their own. Thinking about the essence behind this phenomenon is actually because smart contracts allow publishers to customize all the codes of the contracts, and it is rare to reuse existing codes directly. By copying and pasting, the chain is safe. In fact, the design of the dark forest subtraction protocol tries to repair this. We separate the basic element function in the programming language from the basic element asset concept in the blockchain. In the intelligent contract, the contract code handles the contract asset, while in the subtraction protocol, the function has the authority to operate an asset, such as the authority to operate all assets, which makes it unnecessary for people to rewrite all the codes for each asset, but requires a higher definition freedom for the method. The logic of assets is necessarily different from the way logic of assets, so it is necessary to write a specific function. In addition, the function also has an attribute that specifies other functions that the function depends on more statically, and makes more detailed restrictions on the types of assets that can be operated by the calling function to improve security. Third, we have always liked the idea, but because it appeared later, all assets cannot be bound to one address, just like the public key and the private key are one-to-one. Assumption of binding: I suspect that my private key is unsafe. When trying to change the private key, it means that the address must be changed at the same time. The user needs to transfer all assets to the new address, which will cost a lot of money. Therefore, we think that the security cost of changing the private key will be high. In the subtraction protocol, we can improve the protocol design. We allow assets to be held by one name and can bind the address, so changing the private key does not require changing the name to reduce the cost. We are designing and implementing the subtraction protocol, which is a cross-chain inscription space under the guidance of subtraction theory. Our progress is very optimistic, and it took only one week from running to testing, so please look forward to it in the near future. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
