All blocks Arbitrum
Every recent Arbitrum block, newest first, with transactions, gas used and base fee. Open a block for its transactions, or page back through history. Arbitrum is so fast that the backend keeps a sample of the newest blocks, so some numbers are skipped.
Reading the list of Arbitrum blocks
An Arbitrum block is produced by the sequencer, which orders transactions on layer 2 about four times per second. Its gas limit is not a capacity, so the share of gas used says little. Each transaction pays a layer 2 fee plus a data fee for posting to Ethereum, and the data is later finalized there.
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 Arbitrum 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.
