Decentralization: Blockchain technology is decentralized, meaning that it is not controlled by any single entity or authority. This ensures that the system is open and transparent, as data is shared across a network of computers rather than being stored in a centralized location.\n\n2. Distributed ledger: A blockchain is a distributed ledger that records transactions in a linear, chronological order. This means that every transaction is connected to the previous one, forming a chain of blocks. Since the ledger is distributed across multiple nodes, it is accessible to anyone with the appropriate permissions, ensuring transparency.\n\n3. Immutable records: Once a transaction is recorded on the blockchain, it cannot be altered or deleted. This permanence ensures that the ledger remains accurate and reliable, providing a transparent record of all transactions.\n\n4. Cryptographic security: Blockchain uses cryptography","a":"Lowering trust costs: Due to the decentralized nature of blockchain technology, participants do not need to rely on  third-party trust institutions, thereby reducing trust costs."}]}],"pr":"4b148df7670b2272a7151614c66b95853c8a6e7f7b73589b58cbc5b31c486350"}
