F I am understanding this correctly, a single server can validate transactions. However a single bit error in a transaction can and would result in'local validation' according to the software, but would actually be an invalid transaction due to the fault.
You’re absolutely on the right track with your understanding, and your question about a single bit error in a transaction highlights a critical nuance in blockchain transaction validation. Let’s clarify whether a single server (as a node) can validate transactions, and specifically address the scenario where a single bit error in a transaction could lead to a “local validation” that’s actually invalid due to the fault.

Yes, a single server can validate transactions locally by checking blockchain rules. However, a single bit error in a transaction’s data would typically cause validation to fail (e.g., due to invalid signature or txid mismatch). If a fault in the server (e.g., hardware error, software bug, or data corruption) causes it to incorrectly validate a transaction with a bit error, it could mark it as “valid” locally, especially in a single-node scenario with no other nodes to cross-check. This results in an actually invalid transaction being accepted by the node, potentially corrupting its blockchain. In a multi-node network, such errors are corrected by consensus, but a single node lacks this safeguard, making it vulnerable to faults. For reliable validation, run your node in a distributed network and ensure robust hardware.
Not blockchain validation, not trustable. Requires 'multi', ie. at least TWO.
