Transaction Validation Error

Definition ∞ A transaction validation error occurs when a proposed transaction fails to meet the specific rules and criteria required for inclusion in a blockchain block. This rejection can be due to insufficient funds, incorrect cryptographic signatures, invalid smart contract parameters, or a violation of protocol-level constraints. Nodes on the network perform these checks to maintain the integrity and security of the ledger. An invalid transaction will not be processed or recorded on the blockchain.
Context ∞ News reports may mention transaction validation errors in the context of network congestion, smart contract bugs, or user interface issues that lead to incorrectly formatted transactions. Understanding common causes helps users troubleshoot and developers improve system robustness. Proper validation is fundamental to the security and reliability of any digital asset network.
