# Blocks
In this page you can browse all the blocks in the Avalanche ecosystem. \
Each block contains a group of transactions and many other data; thrugh cryptographic hashes and the linking of block headers those informations are passed to the next one.
### Page structure
This page is accessible by clicking from the homepage on **Blockchain** and then **Blocks**.
The results are displayed in different columns:
* **Height:** a numerical value that represents the position of a block within the blockchain
* **Age:** how much time ago the operation happened including date and time
* **TXS:** the number of transactions involved in the block
* **Hash:** the unique identifier for the block
* **Gas Used:** the amount of gas spent for the operations
* **Total burned:** the amount of token burned in the process
* **Volume:** the volume of gas token used in all the transactions inside the block
* **Size:** the capacity of the block, expressed in bytes
* **Chain logo:** on which blockchain the block has been executed
By clicking on "height" or "hash" in a single row you'll be redirected to another page that includes all the block details with many additional data.
