The page we used to track blocks last time was https://tzkt.io/. This website is a great resource for tracking blocks on the Tezos blockchain. It provides a visual representation of the blocks and the transactions associated with them. It also provides detailed information about each block, such as the timestamp, the block hash, the miner address, and the number of transactions. Additionally, it provides a variety of charts and graphs that can be used to analyze the data. It is a great tool for anyone looking to get a better understanding of how the Tezos blockchain works.
