Telegram's blockchain governance model for TON (Telegram Open Network) was designed to involve various stakeholders in decision-making. Key elements included:

1. **Validators:** These were nodes responsible for validating transactions and creating new blocks. Validators played a crucial role in the consensus mechanism and had a say in the network's governance.

2. **Token Holders:** Like many blockchain systems, token holders had influence. The amount of tokens held often correlated with the weight of one's influence in decision-making processes.

3. **Smart Contracts:** The governance structure also extended to smart contracts, which could automate certain decision-making processes based on predefined rules.

4. **Decentralized Autonomous Organizations (DAOs):** Telegram envisioned the use of DAOs as a form of decentralized governance, where community members could participate in decision-making through voting mechanisms.

It's important to note that the TON project faced regulatory challenges, leading to its eventual abandonment. As a result, the planned governance mechanisms were never fully implemented or tested in a live environment.
