Node Selection Criteria

Node Selection Criteria refers to the specific set of parameters and requirements used by a blockchain network to determine which participants are eligible to act as validators or block producers. In proof-of-stake systems, this involves assessing the amount of staked capital, the node's uptime, and its technical reliability.

These criteria ensure that only nodes capable of maintaining network security and consensus integrity are chosen to participate in transaction validation. By filtering for performance and economic alignment, the protocol mitigates risks associated with malicious actors or unstable infrastructure.

Effective selection criteria are essential for maintaining decentralization while ensuring high throughput and fast finality. They often balance the need for low barriers to entry with the requirement for robust network defense.
