Network Security Upgrade
We have released a security patch and have notified the mining pools to upgrade their Kevacoin nodes. We will disclose the vulnerabilities once the security upgrade is activated. The vulnerabilities are not related to Kevacoin creation or transactions, and your assets are safe.
There is a BIP9 upgrade currently underway. It is normal you see a warning like this:
Warning: Unknown block versions being mined! It's possible unknown rules are in effect.

This is MASSIVE! Hackers pumping a crypto giveaway scam appear to have compromised the Twitter accounts of leading exchanges, individuals and at least one news org.
https://www.coindesk.com/hackers-take-over-prominent-crypto-twitter-accounts-in-simultaneous-attack
By using Twitter, you put the security of your account in the hand of a private entity. This massive attack speaks for itself how secure Twitter is.
If Twitter/Micro-blogging is done on Kevacoin, users are in charge of their private keys, and so is completely in charge of the security of their accounts (namespaces). And, a 51% attack cannot tamper the messages, it can only rollback the messages.
We are working on a micro-blogging feature on Kevacoin this summer on our mobile wallets.

KIP 010 first draft for comments:
https://github.com/kevacoin-project/kips/blob/master/kip-0010.md
This KIP describes the feature of Namespace Access Control (NAC) for Kevacoin key-value database. It allows the owner of a namespace to assign the write access to other users. It also provides the options to limit the write access to certain key patterns, i.e. the user can only create or write to keys that follow the given regular expression patterns. And finally, it allows the original owner of the namespace to revoke the access to the other users.

Zoom Acquires Keybase.
The centralized identity management startup Keybase is no more. Kevacoin + W3C's DID (https://www.w3.org/TR/did-core/) is the way to go.

Hello admin, i checked your website and go to the tutorial and click 'How to publish a web page on keva blockchain' link,
but there is only 'undefined' text displayed. Please fix your website because i want to know how to use the coin on the network.
Here is the link : https://kevacoin.org/tutorial.html

Thanks for reporting the issue! We have fixed the link and you should be able to see it now.
Here is the direct link to the tutorial:
https://explorer.kevacoin.org/ns/html/NceXtbgQD92zrVM7QUnfNhrRcj2DQ1PewD
For now, you will need the command line tool "kevacoin-cli" to read and write Keva database. We are adding a cool GUI interface to the GUI wallet to make it extremely easy for anyone to use. We will release it soon, please stay tuned!
You can think of the namespace as the "IP address" on the blockchain. Anyone can set up their name service (i.e. DNS for the blockchain) to map the namespace to a human-readable "domain" name.
Thankyou for fixing the tutorial, i hope keva will become a great coin someday.
