1.昨天遇见了还是以前遇见的问题,就是发现有些函数就是不能用web3调用,然后怎么弄都写不到数组上,但是今天终于将它解决了web3的学习:https://github.com/ethereum/wiki/wiki/JavaScript-API 今天又重新想要跑一下cryptopunks当想要在私有链配置自己的合约的时候,有时你会很残酷地发现它告诉你out of gas,这个时候你就要去查看你的初始块配置的时候的gasLimit是不是设的比较小了,或者是你部署合约的时候gas给的是不是太小重新又创…

区块链扩容一直是区块链团队的重点研究方向.因为比特币对区块大小的设定是固定的,而且中本聪将最初大小值限定为1M,但随着交易量的增加,网络拥堵情况也愈渐严重,最终也导致了比特币的分叉. 区别于比特币固定区块大小的设定,以太坊则引入了燃料(gas)的概念,并采取了区块燃料限制(Block Gas Limit)动态调整机制,即根据交易量大小来调节Block Gas Limit.通常我们以TPS来衡量区块链的交易处理能力, Block Gas Limit值越大则意味着允许区块打包的交易量也就越多,也就是…
