Introduction– According to (Cryptocurrency wallet – Wikipedia, n.d.), a cryptocurrency wallet is a device, program, or service which stores the public and/or private keys and can be used to track ownership, receive or spend cryptocurrencies.

Up to now, the blockchain wallet was mostly used for cryptocurrency asset holding and exchange.

Solution– The 4thtech add-on is a Google Chrome Extension wallet, that allows you to visit the distributed web of tomorrow in your browser today. It is one of our main innovations, a system capable of handling not only digital assets but also other assets such as links to encrypted electronic data and documents.

Solution Design– Designed and built from the ground-up, the 4thtech add-on is fully operational and also offers a secure identity vault, providing a user interface to manage digital identities and sign blockchain eDelivery transactions. 4thtech add-on can be comparable to a bank account, as it contains a pair of public and private cryptographic keys. A public key allows for other wallets to execute eDelivery to the desired wallet’s address, whereas a private key enables the decryption of electronic data and documents from that address.
