 ## Which mode should I pick?
 
-- **Need the lowest cost and fastest confirmations?** Start with the [Proof Verification Layer](https://docs.alignedlayer.com/architecture/1_proof_verification_layer). It’s live on mainnet, secured by 52 restaked operators, and can verify thousands of proofs per second with results readable on Ethereum within blocks (cryptoeconomic security derived from Ethereum).  
-- **Need full L1 finality in one transaction?** Use the [Proof Aggregation Service](https://docs.alignedlayer.com/architecture/2_aggregation_mode). It recursively compresses many proofs into one that’s verified directly on Ethereum, trading minutes of latency for the strongest security (full cryptographic security of Ethereum).

 In the current Holesky testnet deployment of the Proof Aggregation Service, supported Risc Zero and SP1 zkVM proofs that are submitted to the Proof Verification Layer are aggregated and verified through the Aggregation Service several times per day. The mainnet version will allow users to choose either the Verification Layer or Aggregation Service (or both) when submitting proofs.
