KeeeX records at will proofs of existence of any of your files on the Bitcoin blockchain. On course, one may use this for very serious things : contracts, certified diplomas, minibonds, proofs of ownership or insurance claims…
But we may use this to immortalize our selfies forever! Specially with the latest KeeeX for Android beta, that is readily available. One full month free testing under the current terms.
For photographers and authors KeeeX also allows for injecting your copyright settings straight inside the document you’re publishing.
