Blockchain mainly works on the Authenticity characteristic of data.

Here's a step-by-step explanation:

1. Blockchain is a type of distributed ledger technology that stores data across multiple systems in a network to ensure data security and transparency.

2. The main characteristic of data that blockchain works on is Authenticity. This is because each transaction on a blockchain is encrypted and linked to the previous transaction.

3. This forms a chain of blocks (hence the name 'blockchain') where each block contains a unique code called a hash. This hash is created from the transaction data and ensures that the data is authentic and hasn't been tampered with.

4. If someone tries to alter the data in a block, the hash will change and it will no longer match with the hash stored in the next block. This makes the blockchain secure and ensures the authenticity of the data.

5. While blockchain also ensures the availability and originality of data, its main focus is on the authenticity of the data. Analytics is not a primary characteristic of data that blockchain works on.
