WCAHT Chain

A fast, pure-EVM, MetaMask-native digital value network.

1. Abstract

WCAHT Chain is a high-throughput Layer-1 blockchain built for one job done well: moving digital value quickly, cheaply, and with a wallet experience users already know. It pairs a parallel transaction engine with a BFT consensus core and ships a native MetaMask integration, so any existing Ethereum wallet can hold and send WCAHT with no new software.

The network is engineered around four commitments: parallelism first (non-conflicting transactions execute concurrently), deterministic consensus (every honest node computes byte-identical state), familiar access (MetaMask-native), and honest engineering (performance is measured on-chain, not theoretical).

2. Architecture

WCAHT Chain is an independent Rust implementation — not a fork of Solana, Ethereum, or Cosmos — composed of named subsystems:

2.1 Consensus (Skyfall)

Slot time is 400 ms (2.5 slots/second). Consensus is stake-weighted BFT with a published, deterministic leader schedule and supermajority (≥2/3) finality. State roots use an incremental bank-hash model — Hash(ParentRoot ‖ Hash(sorted delta)) — with domain-separated, length-prefixed hashing so all nodes agree bit-for-bit. Duplicate-transaction detection is ancestry-based (a pure function of a block and its parent chain), eliminating the class of node-local disagreements that cause forks.

2.2 Parallel execution (TxFabric + Prism)

Transactions declare the accounts they touch. TxFabric groups non-conflicting transactions so Prism can execute them in parallel across cores, while conflicting transactions from the same account are serialized for correctness. A single block can carry up to 50,000 transactions.

2.3 Access layer

WCAHT is a pure EVM chain, added to MetaMask as a custom network — users see balances and send WCAHT directly. A live explorer and dashboard show network status, search, validator health, and TPS.

3. Performance

Every figure below is confirmed on-chain (transactions counted inside finalized blocks), measured on the live multi-node testnet — not accepted-count or theoretical.

4. Token

WCAHT — smallest unit 1 WCAHT = 1,000,000,000 (10⁹) kak. Utility: transaction fees, staking for consensus participation, and value transfer. Full distribution and emission are published in the Tokenomics document ahead of mainnet.

5. Security & Determinism

Ed25519 signatures with domain-separated canonical encoding; TOFU certificate pinning on the QUIC transport; recent-blockhash replay anchoring; disk back-pressure read-only mode; per-IP rate limits; and a production-profile guard that refuses unsafe environment overrides on validators. Consensus execution never consults node-local caches — the duplicate set and state delta are pure functions of the chain. An independent third-party security audit is a mainnet gate and has not yet been completed.

6. Current Status (July 2026)

Testnet — live and iterating. BFT consensus, parallel execution, and finality run on a live multi-node cluster; MetaMask-native WCAHT (view + send) is operational; the explorer and dashboard are live; and major consensus-determinism hardening is complete (a fork-class bug in multi-transaction blocks was identified and fixed, with zero state-root divergence under load). In progress: sustained high-throughput transport, single-validator liveness/failover, and pre-mainnet security hardening.
