Details

ckb: Large dep group requires a lot of resources to process but the cost to commit the transaction is very low. ### Impact When a transaction contains a dep group with many cells, the resources required to process it are not linear to the transaction size nor spent script cycles. ### Patches In 0.43.3, nodes drop the transactions relayed to them when they contain a dep group with more than 64 cells. They do not ban peers who send them such transactions. In 0.100, the consensus disallow transactions using a dep group with more than 64 cells. Peers relaying such transaction must be banned. Blocks committing such transactions must be rejected.
