修改且得到长于当前链长度的新链才有可能被其他节点支持，你这说法奇奇怪怪的，prehash包括了一些高度时间戳这些不能复制的数据，你不是随便替换掉其他block的位置就可以，要做的话你要自己重新算所有的hash，这就是51算力攻击啊，有那么多算力是可以改，问题就是谁可以搞到这么多算力，说dpos防修改这你要看看文档了

I don't think bitcoin will die before some other thing have replace it, because a lot people need this kind of thing.

Quote from: Herlina on December 29, 2017, 10:24:37 AM Quote from: 5ToMessager on December 29, 2017, 09:34:22 AM I use ethersan(https://etherscan.io/), and just input my address, then every transactions show. Why Ethereum don't need authorization to access user's info? Is it any benefit to do so? I think if someone know my address(maybe have trade with me once) and pay enough time, he can figure out who i am in real world, and even find my secret by analysing my transactions. Because Ethereum is a public blockchain it's a blockchain that can be read by anyone in this world and anyone in the world can participate in the consensus. Public blockchain are generally considered to be “fully decentralized” and this corresponds to Ethereum to be decentralized platforms that runs smart contracts "applications that run exactly as programmed without any possibility of downtime, censorship and fraud" But could it just encrypt the detail of the transaction?

I believe that digital currency will be a important payment for even daily life. At that time it's not hard to relate someone with his address, then if all the transactions is public (you can find them just using a address), it's horrible I think.

Quote from: Timeme on December 29, 2017, 09:39:29 AM Maybe you don't know much about blockchain, blockchain transactions are public, you can check randomly, you can buy some relevant books to learn about blockchain knowledge. i have read some document, and blockchain should have this function to controll which part of ledger is visible for a particular user.(https://www.coursera.org/learn/ibm-blockchain-essentials-for-developers/lecture/eMOaR/requirements-deep-dive). And bitcoin did enable this function.

java 就是一门很大众的编程语言而已啊，他有什么创新的点么？现在本地钱包都多了去了，中国应用市场很多不让放罢了
