The governance structure of STEEM, which involves the stakeholders called Witnesses, plays a crucial role in how transactions are sequenced and network security is maintained. The Witnesses, who are chosen by the community through voting, validate transactions and make changes to the network. This democratic approach ensures that decisions are made collectively.

When it comes to transaction sequencing, the governance structure allows Witnesses to order transactions in a way that maximizes network efficiency and prevents issues like double spending. This ensures that transactions are processed smoothly and securely. Additionally, the governance structure of decentralized platforms like STEEM enhances network security by distributing control and reducing the risk of a single point of failure.
