Blockchain
A distributed ledger technology characterized by immutability, applied in supply chain traceability to enable trustworthy storage of labor records and wage payment evidence. It supports compliance audits aimed at detecting and preventing forced labor within global supply chains.
Core Facts
Timeline (last 90 days)
Web3 is the next-generation internet form built on top of blockchain technology, whose core promise is to provide greater security and privacy protection, letting users control their own information through a decentralized architecture.
Web3 and DeFi share the same technical foundation, blockchain; Web3 provides decentralized infrastructure at the identity and data layers, and DeFi builds financial applications on top of it, with the two supporting each other.
DeFi (decentralized finance) is built on the same blockchain foundation as Web3, with the goal of providing a financial services model that is safer and more efficient than traditional financial institutions, letting users create their own decentralized financial applications to participate in the value distribution of the digital economy.
Decentralization comes with trade-offs in performance and cost; transaction confirmation speed and fees fluctuate with network congestion.
A blockchain's ledger is jointly maintained by numerous nodes in the network, and no single node can modify records on its own; its core characteristics include decentralization and verifiability.
A blockchain is essentially a distributed ledger, where data is packed into blocks and chained in chronological order, with each block containing the hash of the previous block, forming a chain that is difficult to tamper with.
The marginal cost of blockchain settlement is mainly reflected in Gas fees rather than proportional commissions, and x402's facilitator model can further externalize this portion of the cost.
Once a transaction on a public blockchain is confirmed, it is almost impossible to revoke or roll back.
The 'proof of work' in this scenario relies on geolocation, timestamps and human visual judgment, not on computing power as in blockchain.
Once a cryptocurrency transfer is confirmed on-chain, it is irreversible; no bank customer service can freeze the transaction, no credit card company can initiate a chargeback, and no central authority can force a rollback.
