Factom Entries

Once data has been published as an entry in the Factom Blockchain, what happens next?

First, the entry is assigned to a chain. This allows users to look up information more quickly and keeps applications on Factom running light. This is means they only need to keep track of the data that they are interested in for their applications.

How does Factom take all the entries and reduce them to something that fits in a Bitcoin entry?

Factom utilizes Merkle Trees to create perfect cryptographic evidence of data. The graphic depicts how Factom takes entries, that could be documents for example, and combines the hashes until there is only one left. This becomes the root hash.

The root hash of each block is placed as an entry within the next directory block. Publishing the Root Hashes in this order, locks the directory blocks together and prevents tampering that would otherwise go unnoticed in other systems.

Factom has another security feature to create more data integrity. The root hash for each directory block is also published in the Bitcoin blockchain and other distributed sources. Like the root hashes placed within each directory block within Factom, these hashes lock the Factom blockchain in place and help reduce the threat of data being rolled back.
