Blockchain serves as a decentralized, immutable ledger that records every transaction transparently and securely. Through cryptographic techniques, it maintains transaction integrity and allows users to verify and validate their holdings without the need for intermediaries. This technology supports various cryptocurrencies, enabling peer-to-peer transfers while ensuring the security and transparency of the entire network, thus fostering trust among participants in the ecosystem.
