# 3.1.1 Reasons for using blockchain

On the blockchain, AQA stores records of project participation by users participating on the network. As a result, even anonymous users may keep a record of their involvement in a project, allowing project owners to feel secure in obtaining expert assistance. We discovered that using blockchain is the most effective way to keep track of these records.

Blockchain has features such as tamper resistance and transparency. Because of the independent decentralized management of its transaction ledgers, the history of acts recorded on the blockchain is freely documented and the validity can be checked. Transactions for services performed by a certain firm are closed within the company's database, which means that the veracity of the information supplied by the company cannot be guaranteed, and the company risks being destroyed if a malicious attack occurs.

Blockchain technology addresses these issues as well as the question of "whether a professional working with an anonymous account was truly involved in the project" (with the possibility of NFTing the record).
