According to @adam3us, a Bitcoin node verifies transactions and block validity and protects users from forks, but it cannot directly prevent spam transactions from being included in blocks.

He adds that only consensus validity rules can be enforced collectively across the network, whereas non-relaying spam at the node level has little effect unless the node is used for mining and chooses not to mine such transactions.

For traders relying on on-chain settlement, this means spam resistance depends on miner inclusion policies and consensus changes rather than individual node relay settings, so monitoring confirmation times and miner behavior is more actionable than tweaking relay policies.

According to BitMEX Research, a slight discrepancy was identified in a recent Bitcoin block timestamp, which was off by only one unit. Such timing discrepancies can have implications for trading algorithms and block validity checks, as they rely on precise timestamps for transaction verification and trading strategies. BitMEX Research highlights the importance of accurate timestamping in maintaining the integrity of blockchain data.
