Blockchain//Besu//Stall

Network "stall" = blocks stop being produced, transactions stuck in mempool forever.

Network "stall" = blocks stop being produced, transactions stuck in mempool forever.

Most common cause: quorum failure — not enough validators online to reach floor(N/2)+1.

2-validator network: if either goes down, the network stalls immediately (quorum = 2)

RPC still responds to read queries, but write operations (transactions) never confirm.

Diagnosis: check peer count on each validator, verify P2P connectivity between them.
