XDV Node — June 2021 Updates

Starport Cosmos just rocks

Our new chain project is looking good. Here are some updates and research notes:

Business

• We got a very interested partner, kind of VIP in the electronic invoice industry, approving our work and research with electronic invoicing, blockchains and how to sign with RSA algorithms
• We met with an European company interested in did-jwt-rsa and Smartcards. We got great feedback.
• DIF Wallet Security WG is done, and we will be there.

Technology

• We manage to grasp go-ipld-prime not that hard, now we need to test it out and see if the following are correct:

1. Chain is able to transact using an IPLD transaction message like
2. Chain is able to fetch an IPLD node
3. Chain is able to offer data storage types eg Arweave, IPFS, Swarm, Sia.

If we manage to do this, is possible to create a chain that manages built in CID/multiformat/multihash and have native storage or chunk based storage.

• With AnteHandler we can actually pursuit the dream of signing with RSA directly into the blockchain. XDV Node will likely support elliptic curves secp256k1, ed25519 and RSA out of the box.

NFT

• We have been doing NFT lately using our open source XDV Publisher Contracts. What amazed me is how advanced we made it, it is very targetted towards secure documents being exchanged vs simple NFTs.

Swarm

• As grant recipient, our intention is to have something mid August 2021 using fds.js/bee.js. I know many of you are waiting these features since we released XDV back in August 2020 with Swarm v1 backend.
• We might collaborate with more grants around the fairdrive improvement process.
