The Handshake

Brothers sitting and meditating together in a dusty kitchen. Sam is behind the royal KMG typewriter he has never seen before, and he nostalgic to do keystrokes. His brother, Willem, took a note about the tablet. The room was almost quiet except for the drip of the faucet. Its fast pace, obviously distracting Sam. "I want my mother to hire a plumber, but that noise is unbearable," Sam said ironically. William answered his brother 's self - indulgence complaints, had this patience and reservation, and laughed at his brother.

Hello! I am the lead developer of Trong, Handshake. This article is a sequel to the handshake protocol and explains how to use Solidity to implement a handshake in Ethereum network. It also shows how to use truffle to make development easier. The two main contracts Handshake uses are BasicHandshake and PayableHandshake. Compile the source code (.sol file) and get the bytecode and ABI of the contract. The source code is compiled into binary bytecode for efficient storage as the contract needs to be executed on all machines in the Ethereum network. Another part of the ABI is the public interface of the contract. For example, in the following agreement, when a customer wants to perform functional jitter, it is necessary to specify two parameters of the correct type (Hidden and Off Chain). ABI will save this information on the client

A connection established via SSL / TLS will always perform a "handshake" before exchanging the actual application data (such as username / password). During this handshake, the two parties establish a secure (encrypted) connection and establish the identity of at least one party. There are several steps to handshake, including asymmetric encryption and symmetric encryption. Both will negotiate a "password suite" for this connection. The cipher suite includes a symmetric encryption algorithm (AES is a common choice), an encrypted hash algorithm (SHA-2 series is a general option), and to ensure that each handshake is universally unique It contains a random value called nonce of. )
