The project is in development, early alpha and may contain errors.

Who is Coin for? First of all, for people who need to save their data such as pdf, jpg, png, gif, doc, xml, txt attachments and be sure that it will not be lost. Do you have any souvenir photo, e.g. from a wedding, Holy Communion Etc. or you have some certificates saved in PDF, save to blockchain and you can sleep peacefully as long as users like you save their attachments in the Coin network. All attachments are encrypted before they reach the blockchain, and only you have the key to decrypt them, even if someone gets access to the block, you won't be able to decipher them all thanks to Coin entanglement, only you are entangled with your attachments. Coin will work as long as users want to use blockchain, and your data will be safe there and always available regardless of the time of day. Coin is also open to everyone who needs to save their work in a place from which they always have access, and who do not want to send it via e-mail, want to remain private. The code is written in PHP with connection to a relational sqllite database, completely centralized. The whole is to run on servers that support PHP and sqllite. Once added, attachments are forever on the Coin blockchain and can no longer be deleted. This gives you a lot of possibilities, such as adding license files with the exact date added to reproduce the day of addition.

Proof of Work (PoW) has been implemented at the moment. Work on Proof of Stake (PoS) is underway.

For proper operation you need the implemented php_mcrypt.dll library on the server.
