According to the latest news, MicrosoftOffice users can now bitcoin blockchain help create immutable document. In April 10th, a massive Stampery document authentication and verification application is added to the international technology giant MicrosoftOffice program.

The MicrosoftOffice add-on is bitcoin blockchain authentication function

Microsoft showed that the application of bitcoin blockchain support has continued for a long time. Now, a company engineer VilleRantala announced the launch of the MicrosoftOffice suite of Stampery block attachments.

The Node.js server as Azure application service to run, and retain a copy of the hash, for later verification, and then use the hash function call StamperyAPI. The Stampery service will be put into the hash value of the public Ethereum and bitcoin blockchain.

Validation: press the verify button, again from the call in Javascript authentication function, the file hash table Node.js to send the file to the server as REST calls. The original hash Node.js server then calls StamperyAPI to access from a two block chain document.

Notary individual and enterprise customer solutions
