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
There are N gas stations along a circular route, where the amount of gas at station i is gas[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from station i to its next station (i+1). You begin the journey with an e
A gas station has to be built at such a location that the minimum distance between the station and any of the residential housing is as far away as possible. However it must guarantee that all the houses are in its service range. Now given the map of
