# Nethermind tests show a self-funding privacy pool works on Ethereum frame transactions only if the unpaid validation cap rises

On a devnet running two clients, a Groth16 shielded-pool withdrawal used 236,285 gas in its verification step, above the 100,000-gas cap in current client code. Post-quantum signatures also exceed that limit.

Researchers at the Ethereum client team Nethermind published two linked studies of EIP-8141, a proposal for frame transactions. Under that design, an account can run its own validation logic in a dedicated verification frame before the tran…
