BTP 4 - Is Snapshot the answer

As of my last knowledge update in September 2021, "snapshot voting" typically referred to a mechanism used in decentralized governance systems, particularly in the context of decentralized autonomous organizations (DAOs) that operate on blockchain networks.

In decentralized governance, stakeholders in a DAO or a blockchain-based project have the ability to participate in decision-making processes by voting on various proposals, such as protocol upgrades, fund allocations, parameter changes, or other important decisions that impact the project's development and operations.

A snapshot vote is a specific type of voting process that allows token holders or stakeholders to cast their votes based on their token ownership at a particular snapshot block. Essentially, the voting system takes a snapshot of the token balances held by each address at a specific block height, and those balances are used to determine voting power for the upcoming proposal.
