Museum of Named Diamonds allows recording the stories related to diamonds on the Blockchain, preserving them forever. In such a way, people can make their precious diamonds unique by giving them names and stories. Moreover, they can track their history as long as the Blockchain exists.
The Museum partnered with Everledger.io to ensure the technical support for their project. Everledger specializes in recording diamond data on the Blockchain. The company maintains their own distributed ledger which is the database for all the diamond-related content. Jacques Voorhees, CEO of the Museum of Named Diamonds, shared the details of the recording mechanism with CoinTelegraph:
“In our case that is all the data that appears in the Museum, on a given diamond. Everledger takes the content from their own distributed ledger, “hash” it, and place the hash into the Bitcoin Blockchain by recording the hash via a tiny Bitcoin transaction. That has the effect of sealing the hashed data into the BitcoinCT r: 10 Blockchain”.
