SX4 is a specialist blockchain specifically designed to manage and secure archives, and the first and only one to date. It is not based on any open-source material but was coded bottom-up for maximum performance. This is why it is one of the fastest blockchains in the world with more than 60 documents hashed per minute and as many blocks created simultaneously on the blockchain. It has unique features found nowhere else in the blockchain world.
But first, why blockchain? A blockchained archive is stable as it is fixed. An archive solely organised with AI is exposed to disruption. There are many reasons for this starting with the fact than an AI is by essence dynamic. Blockchain is the opposite. A blockchained archive is immutable in content and structure. Once a record is made on the blockchain it is there forever. A un-blockchained one is the opposite and can be tampered with. An entry can be deleted and/or the text of an archive modified. If a blockchained archive (a document, a photo, etc...) is modified, its digital signature changes. If the structure and in particular content of the archive is changed, the chain is broken. This is important if no record is allowed to be removed (shares, birth certificates, degrees, contracts, etc...). In both cases, the alteration(s) can be found.
