Monad's Metropolis hackathon runs six weeks from September 1. ack3's part: an AI scan for every finalist project and a mentor through the build window.
Glossary definition
Protocol
A blockchain protocol is a defined set of rules and software interfaces that participants follow to reach consensus or provide an onchain application service.
A protocol is a foundation layer or set of rules that allows computers to share data. In cryptocurrency, blockchain protocols run on networks of peer-to-peer computers that follow the same rules and maintain matching copies of a transaction ledger. A consensus mechanism allows them to exchange value without a central intermediary.
Well-known blockchain protocols include:
- Bitcoin
- Ethereum
- Solana
- Hyperledger Fabric
- Corda
