The earliest cross-chain bridge: Centralized Exchange (CEX)
CEX is the bridge most commonly used by each of us. In addition, centralized wBTC and HBTC account for nearly 90% of the current market share of BTC-anchored coins. Single-point verification bridges like this can naturally attract a large part of the traffic by virtue of their own credibility in the early days.
With the development of the industry, people are gradually not satisfied with the absolutely centralized management method, so they have evolved a multi-point verification method. After all, the possibility of collective evil is smaller than the centralized method, and it seems more reliable.
Like Polygon Bridge's PoS+Plasma, Solana's cross-chain bridge Wormhole, which uses 19 independent verifiers to verify the network, etc., are all multi-point verification cross-chain bridge methods.
