Election
This document describes the validator election and voting management on the Atlas chain.
Staking
Atlas uses a proof-of-stake consensus mechanism. To participate in block generation on the Atlas network, you need to register as a validator. Currently, to become a validator, you need to lock 1,000,000 MAPO and vote for yourself. Each election sorts validators by the number of votes received and selects the top N validators.
Updating Active Validator Set
After processing transactions and epoch rewards, the active validator set is updated by running an election in the last block of each epoch.
Electing Validators
Validators must have at least a 0.001 proportion of total votes to be considered for election. Therefore, validators cannot have zero votes. This approach helps avoid burning MAPO and limits the number of voters to within 1000.
The number of active validators that can be selected has a minimum target (1) and a maximum cap (100). If the minimum target is not met, the election will be aborted, and no changes will be made to the validator set for that epoch.
Example: Currently there are four validators on the chain:
0x5d643dfb9ae372ce4fdbc80890156e2cd8290846
0xa53516d49a72019692ac69cb42641942597654f6
0x6acdc02223100189d82a958d888f54fa27d60e8a
0xea9efaa232a4567eac21c8c096f8bff84595a244
If for some reason we don't elect validators (number of valid validators is less than 1), we will continue using the above validators. If we select the latest set of validators (meaning the number of new validators is greater than 1 and less than 100), we will replace the above validators with the new validators.
Unstaking
After successful staking (locking), you can unstake (unlock) if needed. 15 days after unstaking, you can redeem your MAPO to your account balance through the withdrawal operation.
Implementation
The Election contract manages locked MAPO voting and epoch rewards, and runs validator elections.
