Definition ∞ Chain history integrity refers to the assurance that a blockchain’s historical record of transactions remains unaltered, accurate, and consistent over time. It guarantees that once a transaction is recorded and confirmed, it cannot be retroactively modified or removed without invalidating subsequent blocks. This property is central to the trust and immutability offered by blockchain technology. Cryptographic linkages between blocks and distributed consensus mechanisms uphold this integrity.
Context ∞ The integrity of a blockchain’s history is a paramount concern in cryptocurrency news, particularly when discussing security vulnerabilities or protocol robustness. Any event that threatens this integrity, such as a successful 51% attack or a severe bug, would be a major news item due to its implications for the network’s reliability. Ongoing developments in blockchain technology consistently aim to fortify chain history integrity, reinforcing the foundational security promise of digital assets.
