Blockchain

A blockchain is a decentralized base of records and global transaction data. It works like a chain formed by several blocks that are divided between computers spread all over the world. The information in one block complements the information contained in the others. Whenever there is a change in one of them, all the other blocks check if that change or addition is correct, validating the information or rejecting it. 

With SOL, all purchase orders from associations and cooperatives are made through the app, which digitally stores the process data. This data is also kept in a blockchain located in the infrastructure of the states of Bahia and Rio Grande do Norte. This way, the information is protected against changes. Any attempt to corrupt the data can be easily noticed and reported, making the audit of purchases even more transparent, secure and efficient.
