blockchains
Cryptocurrency record systems
Blockchains is the plural of blockchain, a digital ledger technology where transactions are recorded in linked blocks across a distributed network.
Each block contains a cryptographic hash of the previous one, making the chain resistant to tampering.
Blockchains underpin cryptocurrencies like Bitcoin but also have applications in supply chain tracking, contracts, and voting systems: Multiple blockchains now compete for developers and users.
