Bitlayer Official Cross-Chain Bridge Tutorial (OKX Wallet): Step-by-Step Guide

Introduction to Cross-Chain Bridges

A cross-chain bridge facilitates the transfer of assets between different blockchain networks while maintaining security and transparency. Here's how it works:

• Core Function: Bridges lock assets on the origin chain (e.g., Bitcoin) and mint equivalent tokens on the destination chain (e.g., Bitlayer).

• Key Steps:

  • Deposit: Users lock assets on the bridge, triggering token issuance on the target chain.
  • Balance Updates: The bridge verifies and updates account balances across chains.
  • Withdrawal: Users burn tokens on the destination chain to unlock original assets.

Types of Bridges:

1. Centralized Bridges: Managed by a single entity (e.g., crypto exchanges).
2. Federated Bridges: Governed by a fixed group of validators (K/N multisig).
3. Trustless Bridges: Decentralized networks with dynamic validators.
