contracts-smart contract. For this reason, Ethereum is known as the Blockchain 2.0, to differentiate it from the Blockchain 1.0, which is the core feature of the digital crypto currency represented by Bitcoin. Smart contracts can be understood as contractual agreements between machines, and automatically execute agreed logic when certain conditions are met, such as in the insurance claims process, where the compensation is automatically released to the Chuxian person if the claim conditions are

events and Logs (Logs) in the etheric square are a particularly confusing concept, and this article helps you to comb through them. Because of the previous article, we discussed the Ethernet square go-ethereum client query transaction list of some methods, this article, we specifically implement a filter of the discussion. Let's see how this approach is used in particular. Focus on the last part. Hope to play a certain role in helping to develop. We begin with the basic concepts and understand t

Have you ever the calling Third-party APIs in your smart contracts? It can be possible using the Oraclize service. The Oraclize service enables smart contracts to access data from a external environment. This is article describes the use of oraclize with Testrpc,truffle,ethereum-bridge. It also explains the smart contract code which calls multiple APIs using Oraclize service. You are are familiar with the Dapp development using TESTRPC and truffle. For using Oraclize service your have to install
