律动 BlockBeats 消息,5 月 11 日,Chainlink (Link) 宣布推出一种可验证随机函数 (VRF),允许生成链上可信随机性。目前该程序正在测试网上进行安全性审查,它将首先与以太坊 (ETH) 区块链尝试集成。 原文链接:https://cointelegraph.com Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats Beats. The program is currently being tested online for Security Review and will first attempt to integrate with the ETH blockchain. According to the law, all processes of generating random numbers can be divided into two categories: true random numbers and pseudo random numbers. True randomness can be generated by some basic procedure, such as rolling dice or flipping coins. PSEUDORANDOM is generated by computation, usually with the aid of the PSEUDORANDOM number generator number generator, PRNG. In practice, the latter is more prominent because it can be easily integrated into a variety of computer applications. The key is to ensure that the random numbers generated by these algorithms are indeed unpredictable. Until now, even decentralized applications have had to rely on random centralized sources. CHAINLINK's solution to this problem uses old cryptographic primitives and utilizes a decentralized incentive mechanism. A smart contract that wants to take advantage of Chailink's VRF, passing a seed to a node, which then uses its key to generate a random number. The results are posted on the chain along with the proof of the password. Anyone can verify it with an oracle public key, just like a bitcoin signature. A malicious node can not return a forged random number because the signatures do not match and the malicious node faces a fine. The first use case currently being explored is lossless lottery pool together. Although it is called a "game" , it is more of a mechanism to stimulate savings. Participating customers lock up the principal and purchase the "deposit ticket" . One vote and one draw will win the reward. But participating users can get their full principal back even if they don't win the Grand Prize. So far, the game's game administrators have been using highly centralized random resources, which could be a source of contention. As for CHAINLINK's solution to some of the game's problems, Chainlink's founder and CEO said, "in Blockchain Games, my view is that decentralized blockchain games will not be affected by centralized games. ". The problem with Centralized Games is that they focus on the idea that the people who create them are manipulating them for their own benefit, or that they are devaluing the goods in the game. " 律动 BlockBeats 提醒,根据银保监会等五部门于 2018 年 8 月发布《关于防范以「虚拟货币」「区块链」名义进行非法集资的风险提示》的文件,请广大公众理性看待区块链,不要盲目相信天花乱坠的承诺,树立正确的货币观念和投资理念,切实提高风险意识;对发现的违法犯罪线索,可积极向有关部门举报反映。 本文来源:Block Beats —- 编译者/作者:Block Beats 玩币族申明:玩币族作为开放的资讯翻译/分享平台,所提供的所有资讯仅代表作者个人观点,与玩币族平台立场无关,且不构成任何投资理财建议。文章版权归原作者所有。 |
