PolyBFT Introduction

PolyBFT is a Proof-of-Stake protocol that enables staking, reward distribution and validator selection via smart-contracts. It also utilizes the concept of voting power and enables bridging functionality.

• It uses Ibft 2.0 protocol as a consensus engine to seal blocks (https://github.com/0xPolygon/go-ibft).
• It has a built-in bridge mechanism that enables arbitrary messages to pass between rootchain to sidechain (aka StateSync) and vice versa (aka Checkpoint).
  • Supports Erc20, Erc721, and any other of the open token specs.
• It uses system smart contracts (https://github.com/0xPolygon/core-contracts) to implement the staking solution of the protocol: reward distribution, validator selection, slashing.

Debug trace functionality

New debug endpoints were added to JSON RPC:

• debug_traceBlock
• debug_traceBlockByNumber
• debug_traceBlockByHash
• debug_traceCall
• debug_traceTransaction

Other improvements

• The native gas token is ERC-20 compatible.
• Several property-based tests added
• Overall quality of the codebase improvements

Important notice

This version is not backward compatible
