# Overview

This is a signet testnet launched by sathub.io, which has the same characteristics as the Bitcoin mainnet. The signet network can be understood as a special case of the POA network. It does not require a large number of node consensus, so the speed of block generation is increased. Currently, a block is produced in about 3 minutes. There are currently three nodes participating in block production, and the node public keys are:
