Transaction Certification

Definition ∞ Transaction certification refers to the process of verifying and validating the authenticity and integrity of a transaction within a blockchain or distributed ledger system. This involves cryptographic proofs and consensus mechanisms that confirm the transaction’s legitimacy, ensuring it adheres to protocol rules and has not been tampered with. Once certified, a transaction is added to the ledger, becoming immutable and publicly verifiable. This process is fundamental to the security and trustworthiness of decentralized networks.
Context ∞ Transaction certification is a core function of all blockchain networks, guaranteeing the security and immutability of digital asset transfers and smart contract executions. News often discusses improvements in consensus algorithms or cryptographic techniques that enhance the efficiency and speed of this certification process, particularly in relation to scaling solutions. The reliability of transaction certification is paramount for maintaining confidence in decentralized financial systems.
