Some updates on what we are working on. We continued working on the public sector project. It becomes very clear that we need a Javascript library to easily access the Keva blockchain and database. We took the suggestion of @DukeFerdinand and started a new Javascript library to do exactly that. You can find the library here: https://github.com/kevacoin-project/keva-api-js

This new library is immediately helpful to the public sector project. We are now able to hook up the front-end with the Keva blockchain. What is remaining is to add the feature of updating Keva data through scanning the QR code on the web page.

We enhanced the ElectrumX server so that it indexes all the key-value pairs. This allows the new Javascript library to quickly retrieve the value given the key and the namespace Id (similar to Kevacoin Core’s keva_get method). If you are running an ElectrumX server, it is strongly recommended you get this latest update. Database re-sync is required as we are adding new indexes.

Hello, what about create some namespace registry for the thematic human-readable resources finding, like a blogs, catalogs, etc? You guys moving your blog intro the blockchain, but I think, some official registry of the other resources provided - will be helpful for beginners.

Also, check please the mobile app, because touchscreen does not respond on my touchscreen (Galaxy J6).

Best of wishes!

This is a good idea! We have been thinking about this since the beginning. It will work like decentralized content curator which everyone can be. It is like blockchain content portal, or similar to domain registrar, mapping the namespace ID to a human readable string.

On the other hand, we have another working solution, each long namespace ID has a unique short code. For example, our official account short code is 32101. Enter the short code in the mobile app and it will show the content.

Season’s Greetings from Kevacoin Project!



As we are approaching the end of 2021, we would like to thank you for your support of the Kevacoin project. We are grateful for your contribution in all aspects of the project, including but not limited to bug reports and fixes, application developments, promotion, mining, mining pools.

We started to see quite a few interesting usages of Kevacoin. As for us, we made significant improvements to the iOS and Android mobile app. Everyone can access the Kevacoin blockchain from their phones, reading and writing messages, creating and selling NFTs!

We took the second half of 2021 contemplating what is next for Kevacoin. The activation of Bitcoin Taproot soft-fork presents a very important opportunity for Kevacoin. The Taproot soft-fork introduces the Schnorr signature in Bitcoin transactions. Schnorr signature provides better support for smart contracts, privacy and flexibility. When used in our innovative on-chain database, it will make the database operations smaller, faster and with better privacy.

Kevacoin project is a fork of Litecoin source code. However, the Litecoin source code is diverging from Bitcoin source code, and is behind in some important features, especially the support of Taproot. In order to take full advantage of the advancement of Bitcoin, we decided to fork from Bitcoin source code and re-implement Kevacoin on top of it. We will make our on-chain database a modular component to make it easy to keep up-to-date with Bitcoin’s improvement, and potentially reduce the attack surface and improve the security, performance and stability of Kevacoin.

It is important to note that this new implementation is fully compatible with the current implementation, and has no impact on your Kevacoin holdings. The activation of Schnorr signature is a soft-fork, which requires the support of miners and mining pools. We will communicate with the community to keep everyone up-to-date to our progress.

Another interesting research project we want to start in 2022 is a fully decentralized, high capacity, off-chain database built on the foundation of Kevacoin blockchain database. It is conceptually similar to IPFS, with the major difference that we are envisioning a federation of databases, while IPFS is for static files. This new decentralized database, once it is available, could make web3 applications much more close to reality.
