The 3 Blockchain Networks within IOST

There are three different blockchain networks in IOST. They all run iServer and can communicate over gRPC, HTTP, or ipfs. Each network has a unique Chain ID which you, the developer, will use to select 1 of the 3 networks before action is taken. What action? Actions such as API calls, Smart Contracts, or accounts balances are accessed.

As a developer the Chain ID is very important. Confirm the Chain ID is set properly and it will prevent you from running tests on the mainnet by accident or sending important transactions to the testnet by accident and it will allow you to target your Local Node when developing on your laptop.

The three blockchain networks are explained:

Local Node – Running Isolated MainNet
