All blocks Optimism

Reading the list of Optimism blocks

An Optimism block is produced by the sequencer every 2 seconds. It holds transactions up to the gas limit, each paying an execution fee on layer 2 and an L1 data fee for the copy posted to Ethereum. Once that copy is on Ethereum the block is safe, and it is final when Ethereum finalizes it.

The newest block is at the top and the list moves back in time as you page down. The age column counts from now, the transaction count says how busy the block was, and the fee columns show what its senders paid. Open any row for the transactions inside it. Every block refers to the one before it by its hash, which is how the list forms a single chain, and the numbers rise by one with each new entry unless one was skipped or the backend keeps only a sample of a very fast chain.

The data is read live from public Optimism nodes and indexers. Very recent blocks can still be replaced on a chain that has not finalized them yet, so use an older row when you need something that will not change. The next page button goes further back in time, and the search box in the header finds any block by its number or hash.
