This page describes the historical Whitechain Layer 1 blockchain. It is useful for understanding Whitechain’s history, but does not reflect the current state of the network.
Whitechain launched as an EVM-compatible Layer 1 blockchain built on go-ethereum, secured by Proof of Authority consensus operated by WhiteBIT. The L1 chain ran with 2-second block times, a fixed 10 gwei gas price paid in WBT, and a single-validator PoA model. Whitechain has since completed its migration to a Layer 2 network built on the OP Stack, settling on Ethereum via blob data availability. The L1 is preserved in read-only mode for historical queries. This section of the documentation collects the L1 reference material that remains useful for understanding Whitechain’s past architecture, validator design, and developer workflows. For the current state of Whitechain, see the main documentation tabs. For details on the migration itself, see Migration to L2.

​
What is preserved here

  • Background and vision the original mission statement and design principles of the L1 chain
  • Architecture go-ethereum base, Clique PoA, validator network design
  • Wallet configuration how to connect a wallet to the L1 mainnet and testnet
  • WBT how the WBT token was obtained, withdrawn, and used as gas on L1
  • Smart contracts L1 deployment, verification, and proxy verification workflows
  • Run a node the L1 mainnet node guide
  • Bridge the L1 cross-chain bridge reference
  • WB Soul and SoulDrop the L1-era ecosystem program documentation
  • Migration historical reference for the L1 to L2 transition
