Time to Finality
Different chains employ varying consensus protocols, resulting in different finality times. To ensure transaction security, Analog GMP’s attestation service requires a certain number of block confirmations/time to finality on the connected source chain before transactions can be considered finalized.
This number varies based on the connected chain, as summarized in the table below:

Note that the figures in the table above are averages across multiple transactions. These estimates can vary significantly due to many factors, including network conditions and the specific blockchain. For example, for L2s like Arbitrum, the time to finality depends on the time it takes to publish transaction data to their underlying L1 blockchain (Ethereum in this case). In this instance, Analog GMP must wait for the L1 blockchain to finalize.
