Snapshot-Based Voting Power

Snapshot-Based Voting Power is a governance mechanism used in decentralized autonomous organizations where a user's voting influence is determined by their token balance at a specific, pre-defined block height. Instead of requiring users to lock their tokens in a smart contract during the entire voting period, which can be costly and illiquid, this method records the state of the ledger at a fixed point in time.

This approach prevents double-voting and ensures that participants cannot purchase tokens after a proposal is submitted solely to influence the outcome. By decoupling the vote from active token movement, it reduces gas costs for voters while maintaining the integrity of the consensus process.

It relies on the immutability of the blockchain to verify historical balances accurately. This mechanism is central to off-chain voting platforms that later execute results on-chain.

It balances accessibility with security by ensuring that only those who held the asset at the critical moment can participate. The snapshot acts as a digital ledger freeze for the purpose of tallying.

It is a fundamental tool for managing decentralized protocols without sacrificing user liquidity.
