Arweave 第 17 版白皮书解读（一）：空间与时间的穿越

The author believes that the concerned friends must have a more intuitive understanding of the consensus mechanism of this agreement after many previous articles on the iteration of consensus mechanism, but the author himself always has a little doubt. Since the version is so landmark, why doesn't its consensus mechanism have a specific name? I used the speed-limited version mechanism to name it. With this problem, I had an in-depth discussion with the official core consensus mechanism engineer and learned that the simple copy certificate is actually. It's the name of the consensus mechanism. Well, that means that the first edition of the white paper published by the government in, is basically the official interpretation document, but the version number at that time has arrived. The good news is that the iterative process of the consensus mechanism that I read in the previous article may be more in line with Satoshi Nakamoto's vision. These two articles basically cover the important contents of the mechanism, which is enough for friends who want to taste it, but I still decide to make some more in-depth chapter-by-chapter interpretation of the first edition of the white paper, which is for high-level reference. It is necessary for the participants, because if you read its mathematical formulas and modeling arguments, it will be daunting, but perhaps this is the best expression of the beauty of the agreement. Printing across space and time has a far-reaching impact on human civilization, and its appearance has greatly increased the spread and expansion of human information until the emergence of the Internet at the end of the century, which made it reach its peak, increased social transparency and promoted the awakening of individual consciousness. The control and review of centralized organization The information cocoon caused by the intention of centralized distribution to manipulate the spread of information flow is the biggest problem faced by human beings at present. Every year, a certain proportion of useful information is lost, so the birth of it bears the mission of solving this problem. At the beginning of its white paper, it is clearly defined that the protocol is to transmit information in the form of disintermediation in two dimensions: space and time, which are different from data storage on the earth. Storage service is like a time capsule, which not only carries information and data, but also adds the important dimension of time to it. After combining the two, the form of the agreement becomes a permanent information storage system. There are many definitions of the word permanence, which is defined by Oxford English Dictionary as persistent or unchanged indefinitely, while Webster's Dictionary defines it as continuous or persistent without basic or significant changes. Based on these two definitions of permanence, it should be within the maximum possible period. In order to achieve this goal, the protocol needs to have three core principles: encrypted storage proof, a concise encryption proof system to verify the replication and accessibility of data storage insurance fund, a predictable self-executing insurance fund to pay the cost of permanent storage by using the deflationary effect brought by technological progress over time, and the incentive evolution allows the protocol to be long-term by generating and rewarding non-mandatory network upgrades. The main way to achieve them with a healthy iterative mechanism is to achieve the goal through a brand-new blockchain consensus mechanism of concise replication and proof. This is an agreement that can maximize the degree of decentralization while minimizing the computational cost and bandwidth requirements. Together with the matching storage insurance fund, it has built a model to encourage data replication and storage, so that the network can continue to operate in an independent, transparent and predictable way for hundreds of years. The adjustment and decentralization of the Satoshi Nakamoto Consensus. Consensus is a sub-field of distributed computing, which covers the important research that participants in the network can reach an agreement on a certain state, even those who have a competitive relationship. This sub-field has gained extensive attention with the emergence of Bitcoin Satoshi Nakamoto Consensus, which allows consensus to be reached in a competitive and unlicensed environment for the first time. Because of this innovation, Bitcoin has created the first digital currency that does not rely on centralized human actors to manage monetary policy, and it has always been good. After years of good operation, we have gained the inspiration of reaching a consensus from Bitcoin workload proof mechanism and made some adjustments to make it conform to the goal of permanent storage of information in the network. The goal is a global decentralized consensus system composed of nodes, which jointly store multiple copies of all data uploaded to the system. Users who want to store information on the Internet pay a one-time storage fee to the storage fund of the network and upload the corresponding data by transmitting the data to the nodes in the network. When a node successfully mines and confirms a block, the nodes will reach a consensus on the data newly entered into the global distributed database network on a regular basis. A block contains a transaction list, and each transaction contains new data to be stored in the network or its digital currency transfer transaction or both. Mining means that each node also verifies the storage of previously uploaded data while accepting new data into the network. After confirming the block containing transactions, The two main principles of the protocol design are minimalist protocol design, which aims to maintain direct and minimal subjective judgment and promote the broadest possible network consensus. Only when constructing its data structure and algorithm, it uses well-tested encryption primitives to optimize the protocol through incentives, not to stipulate its expected behavior, but to motivate participants to reach their ideal conclusion. If it is the main goal, the concrete mechanism to achieve these results will be the natural protocol that evolves with time, focusing only on permanent and extensible data storage. Under this minimalist and focused design principle, the application layer built on the protocol has a high degree of scalability and composability, and the application scope of the network has become more extensive and diversified, which has spawned a large number of decentralized intelligent contract platform databases and applications in recent years. In addition, efficient proof systems. The requirements for hardware and bandwidth are extremely low, which maximizes the participation and decentralization of the network. The incentive measures for efficient mining in Bitcoin have contributed to a significant increase in the speed of hash calculation and a reduction in cost, and the way of promoting optimization with incentives is also very effective. We take Bitcoin network as an example. Bitcoin rewards miners for finding a random number, which together with a candidate block produces a hash value with a difficulty coefficient lower than a certain value, which encourages miners to constantly find ways to calculate the maximum number of hash values at the lowest cost, so there has been the development of special mining machines that can calculate hashes per second since. 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
