Ethviewer.live

ethviewer.live real-time visualisation of the Ethereum blockchain is now retired. It was operational from late 2017 to June 2024. Following are two of the screencastings of ethviewer.live visualisation of Ethereum versions 1 and 2:

ethviewer.live visualises the recent history of the public Ethereum blockchain. It shows the 24 most recent blocks (the boxes) of the blockchain and the current transaction pool (the group of circles).
All observations are collected by a single full blockchain node we use as the observer. Observations may be slightly different for other nodes. Clicking on blocks or transactions takes you to etherscan.io, a third-party tool, and shows you details of this transaction or block.

  • The chain of blocks: the most recent block is on the top left. Circles in the blocks show transactions included in those blocks. Blocks that become uncles or forks are shown in Red, and blocks in the main chain in Green. Sometimes this changes during observation, but the more blocks are added the more certainty we gain. This highlights why most users rely on some number of confirmation blocks before assuming a transaction is committed. Regular links between blocks are Green lines, uncle links are Red and dotted. In each block, we also display the block number in the first line and the miner who created the block in the second line. Furthermore, the “fuel gauge” in the left upper corner shows how much gas was used by the transactions in the block, relative to the block gas limit: E means empty, i.e., all available gas was used; F means full, i.e., no gas was used, which would be the case for an empty block.
  • The transaction pool: shows transactions currently waiting to be included into a block. When a new block is created, several transactions from the pool are typically added to it. Grey circles represent simple transfers, Yellow circles represent contract invocations, and Blue ones represent contract creations or deployments. Depending on the connection, up to 50 or 500 transactions are shown. These are the most recent transactions that our node received.
  • Ether value in the pool: if shown, is the sum of ether values of all transactions in the pool (not just the ones shown). The corresponding USD value is calculated based on the current average exchange rate from coinmarketcap.com.
  • Extended view (button in the top right corner): groups the transactions in the pool based on the offered “gas price” (related to the transaction fee).
