Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Remote Code Execution: The project integrates external messaging dependencies that have historically contained critical remote code execution vulnerabilities (such as CVE-2019-6250 in libzmq), highlighting the risk of utilizing unpatched upstream packages.

Denial of Service: Consensus rules around block drift limits and coinbase timestamps can be bypassed or abused to disrupt synchronization or stall the network if validation constraints are not tightly bound to clock time.

Logic Error: Flaws in input validation within transaction and block checking logic can allow duplicate transaction inputs or forward-dated transactions to bypass standard consensus filters, causing consensus divergence.
