blockchain

/ˈblɒk.tʃeɪn/Roman

English meaning: Blockchain

English Definition

(English)

A blockchain is a chain of data 'blocks', each cryptographically linked to the previous one and distributed across many computers simultaneously. Once recorded, data cannot be altered without changing all subsequent blocks and gaining consensus from the network — making it highly resistant to fraud. Smart contracts are self-executing code stored on blockchains that automatically enforce agreements.

English Definition

A distributed digital ledger that records transactions across a network of computers in a way that makes records tamper-resistant. Blockchain is the technology underlying cryptocurrencies like Bitcoin and has applications in supply chain tracking, voting systems, and financial services.

Example

India's government has explored blockchain for land registry records — eliminating forgery by creating tamper-proof, publicly verifiable ownership records.

In English: Blockchain-based land registries could eliminate property fraud by creating tamper-proof ownership records.
