How Is the Random Group of PoS Validators Selected in PoA?
The selection of PoS validators is typically based on a combination of their stake size and a randomization algorithm. The larger the stake a participant holds, the higher the probability they will be selected to sign the PoW-generated block.
This random selection process aims to ensure decentralization and prevent pre-coordination among validators. The process often uses verifiable random functions (VRFs).
Glossar
PoA
Mechanism ⎊ Proof of Authority (PoA) is a consensus mechanism where transactions are validated by a limited number of pre-approved, trusted validators rather than through competitive mining.
Verifiable Random Function
Provenance ⎊ Verifiable Random Functions, or VRFs, represent a cryptographic commitment to randomness, crucial for decentralized systems where trustless operation is paramount.
Validators
Role ⎊ Validators are the network participants, typically in Proof-of-Stake systems, responsible for verifying the correctness of new transactions and proposing new blocks to be added to the blockchain ledger.
PoS Validators
Consensus ⎊ ⎊ Proof-of-Stake validators represent network participants responsible for confirming blocks and creating new ones, securing the blockchain through economic incentives and cryptographic protocols.
Verifiable Random Functions
Functionality ⎊ Verifiable Random Functions (VRFs) represent a cryptographic commitment to a publicly verifiable random value, crucial for decentralized systems requiring unbiased selection processes.
Random Walk Theory
Concept ⎊ The idea that price changes are independent and follow a random distribution is a fundamental assumption in many financial models.
