• EVM voting
• Vote decay
• Scaled BP pay
• Self-stake boost

This pull request introduces significant enhancements to the Telos system contract to support EVM-based voting and related configuration, as well as improvements to the voting mechanism. The main changes include new data structures and tables for EVM voting, several new contract actions for managing voting configuration and synchronizing BP (block producer) status with the EVM, and the integration of new libraries for EVM and Ethereum compatibility. These updates enable on-chain management of EVM voting parameters, retrieval and normalization of EVM votes, and synchronization of BP status between EOSIO and EVM.

EVM Voting Integration and Configuration

• Added new tables: evm_vote_info and evm_votes_table to store EVM vote data for block producers, and votingconfig_singleton to hold EVM voting contract configuration and decay parameters. [1] [2]
• Integrated new external libraries (eosio.evm, intx, rlp) for EVM compatibility and cryptographic operations, updating CMake and includes accordingly. [1] [2] [3] [4]

New Contract Actions for Voting Management

• Added actions: setvotedecay, setvotecontr, getevmvote, setbpevmstat, and setselfstake for configuring EVM voting parameters, updating BP status in EVM, and managing self-stake boost multipliers. [1] [2]
• Exposed these actions via action wrappers for external invocation.

State Management and Initialization

• Updated contract constructors and state management to initialize and persist new voting configuration and EVM votes tables. [1] [2] [3] [4]

Voting Logic Extensions

• Added new helper functions for vote weight decay and conversion between uint256 and double, supporting more nuanced voting calculations.
