Kevacoin | Key-Value Data Store on Blockchain

Download our iOS and Android Mobile App and Post Something Today!

If you need some KVA to try the mobile app, feel free to send a direct Twitter message with your address to @kevacoin, and 10 KVA will be sent to you automatically.

What’s Kevacoin?

Kevacoin is a cryptocurrency for the blockchain that supports easy and flexible Key-Value data store. Use it like Redis or other popular data store, except that the data is stored on the public blockchain that is not owned by any entities.

The data store is easy to add, update and access. No programming skills are required and it does not need smart contracts and their associated complications and risks.

Use it for publications, microblogging, public identities, notaries, etc.

Fair Launch

We are committed to a fair launch, with no pre-mining, no founders' reward and no ICO.

Open

We developed Kevacoin as an open-source project. It is not funded by any companies or foundations. We invite anyone who is interested in the project to join us.

Specifications

- Derived from Bitcoin/Litecoin, with convenient key-value data storage and retrieval.
- PoW Algorithm: RandomKeva (a variant of RandomX)
- Port: 9338
- Block Time: 2 minute
- Block Time Retarget algorithm: Digishield (same as Dogecoin)

You do not need to consider it because almost nobody here uses Gitter. Discord or Telegram is more convenient to use and user friendly.

I believe they are false scans. Kevacoin source code is derived from Litecoin. Similar results (even a few more) have been detected from the latest Windows installer from their official website:
https://imgur.com/a/4mq0vDh

We built the Windows installer on Ubuntu using cross-compiler toolchain, to minimize any potential possibility that the Windows OS has been compromised. I.e. our Windows installer is built on a Windows-free environment.

If in doubt, you can always build the Windows version of Kevacoin core from the source code:
https://github.com/kevacoin-project/kevacoin/blob/master/doc/build-windows.md

Not sure if this is problem you encountered, Kevacoin's mainnet is not launched yet. For now, you have to pass the "-testnet" option to "kevacoin-qt.exe":

1. Open the command console (Click the search icon the task bar, type "cmd").
2. cd "Program Files\Kevacoin"
3. kevacoin-qt.exe -testnet
4. Wait for the wallet to sync.

Or you can use my method to enable it.
1. Click [Windows logo]+ R then type Appdata
2. Select Roaming > find Kevacoin
3. Create .txt file with name Kevacoin and insert testnet=1 in the file.
4. Change the file extension from .txt into .conf and then run the wallet.

Yes, you can mine on the testnet. This can be useful to test solo-mining and your mining pool software.

For solo-mining, follow this guide:
https://kevacoin.org/tutorial_solo_mining.html

If you want to start a mining pool, there is a reference implementation:
https://kevacoin.org/mining.html

You can use any miners that support Cryptonight R (variant 4) hashing algorithm.

If you want to implement your own mining pool, it is easier to modify from an existing Crypotnight (e.g. Monero) mining pool software. Kevacoin is derived from Bitcoin/Litecoin, so it is not a privacy coin. But its mining interface has been modified so that it is compatible with Cryptonight stratum protocol and miners.

For the testnet, the address starts with "T". The prefix "V" is for the mainnet. It is not clear from the guide, sorry for the confusion.

How to mine solo?

You can refer to this tutorial:
https://kevacoin.org/tutorial_solo_mining.html

In summary, you will need three pieces of software:

1. The Kevacoin Core/Wallet itself.
2. The proxy/stratum server for solo-mining.
     - We have a reference implementation: https://github.com/kevacoin-project/keva-stratum
     - It is easy to build on Linux. There is a pre-built binary for Windows 10: https://github.com/kevacoin-project/keva-stratum/releases
3. A miner that supports Cryptonight-R, such as:
     - XMRig AMD: https://github.com/xmrig/xmrig-amd
     - XMRig Nvidia: https://github.com/xmrig/xmrig-nvidia

If you have any questions about the solo-mining tutorial, please feel free to let me know.

The source code for mainnet will be released about 6 - 12 hours before the mainnet launch. This is to prevent pre-mining as much as possible and give people enough time to get ready before the launch. We will post a notice here when the mainnet source code is ready.

Kevacoin uses the standard Cryptonight R (variant 4) hash algorithm. So anyone can use NiceHash to mine the coins for their benefit, just like any other PoW coins. We will let the coin economy play out  Wink

Thanks for the reminder. We will produce one soon. The mainnet will be launched on Thursday, Jan. 16, 03:00GMT. The genesis block will give 0.00001 Kevacoin (KVA) to the core developers (the standard block reward is 500KVA for the first 4 years)  Smiley

Kevacoin is unique in that a block can be part of the database storage. We need to find a way to present the key-value relationship in an intuitive and logical way.

Hello! Interesting project, I will keep an eye on it.
Regarding the OP I like it simple like it is, maybe you can put your logo and name on top and that's it.
As for Discord I must agree with @Javi_Anibarro. In the space, Discord is a must. Gitter is unknown, at least to me (first time hearing of it to my shame).

To Buy, or not to Sell? That is the question.

Yes,I just using Xmrig(xmrig-5.5.0-xenial-x64.tar.gz).But there are still errors. Can i have a look your config file?

XMRig CPU's config file is a little bit different. The following config works for us:
Code:
"pools": [
        {
            "algo": "cn/r",
            "url": "stratum.kevapool.com:3333",
            "user": "TFPmyyPLcJDuDu3T3vmEALX87VxrmPLKkj",
            "pass": "x",

Sorry to see that happened to you. This normally would happen when the pool detects there are a certain percentage of shares submitted by an IP address are invalid. If this happens, the pool will temporarily ban the IP address for 600 seconds. If the miners are configured incorrectly, they may send invalid shares to the pool and trigger this ban.

Maybe you can check that the miner is configured properly. If you start to see the pool rejecting the invalid shares, stop the miner right away and fix the miner config. In case of ban, please wait 600 seconds and the ban should be lifted.

As soon as possible, maybe tomorrow. The initial version will not be able to display the key-value database related information though.
For now we will focus on the launch of mainnet. One hour to go ...

Hi,What's wrong


Before we have Discord (a high priority), it would be better to ask this kind of questions on Gitter. Check the link at the bottom of https://kevacoin.org
I agree it is not popular, but if you have a Twitter account, it is easy to sign in.

BTW, you may encounter this issue if the mining pool has not switched to mainnet yet. We don't manage that mining pool, so we don't know for sure, just a guess ...

exchange???

We want to encourage more people to actually use Kevacoin. For this to happen, we probably need exchanges. It was launched about 12 hours ago, so we may need a little bit more time.

We just created a micro-blog on the mainnet. It is easy and fun, and costs very little. So why not try it!

Code:
kevacoin-cli keva_namespace "Keva Blog"
{
  "txid": "c23d373f4e675921e19349a7b6dc3abf5e9146eab9876327443147c390be482c",
  "namespaceId": "Nd25va1gcEFjWgJtzU7Vuu3dG7gWE7G77y"
}

kevacoin-cli keva_put Nd25va1gcEFjWgJtzU7Vuu3dG7gWE7G77y "1" "Kevacoin was launched on Thursday, January 16, 2020, at 03:00GMT. Thank you for your support!"
{
  "txid": "39e848f33fef9f6140804ed358ae82555faac519ceef9806595c870cf4a4657f"
}

kevacoin-cli keva_get Nd25va1gcEFjWgJtzU7Vuu3dG7gWE7G77y 1
{
  "key": "1",
  "value": "Kevacoin was launched on Thursday, January 16, 2020, at 03:00GMT. Thank you for your support!"

Yes! The namespace display name "WWW" is for your own convenience and record, so that you know which namespace is for what purpose. When you call keva_namespace, it will always create a unique namespace id, which you should use in your subsequent Keva operations. This is to avoid name squatting, i.e. the popular names are quickly claimed by speculators without intention to actually use (e.g. in the case of Namecoin).

To show all your namespace, use the command "keva_list_namespaces". It will show the display names and their corresponding namespace ids. The unique namespace id always starts with "N".

Too early to be listed in exchanges.  If you can attract users to actually use your platform, it may add value to your coin. Because without actual usage, this is basically relying on traders, which doesn't have long-lasting impact to its value.

based from your twitter acct, youve been developing this project for a year already. do you think that period of preparation will help you in gaining good momentum once this coin hits the exchanges?

Hi.Nice to read this.
Can we talk about chinese market?Maybe I can help you to let more chinese know this coin.

Yes, very much appreciated! If you can start a discussion thread on Bitcointalk Chinese forum, that would be great!
Just a suggestion, you can translate the introduction into Chinese and post it  Smiley

We also encourage people to spread the word in the language-specific forums!

It is probably downloading the block headers, and will take a while. Please make sure you are using the mainnet release (download it from kevacoin.org).

Yes, we will fix the explorer as you suggested.

Keva project is developed by the developers, for the developers. it is incredibly easy and fun to use. Anyone can start to develop on this platform TODAY. Just treat it as a database, except it is decentralized. We have great hope that it will gain widespread acceptance, and we need everyone's help to spread the news  Smiley

Kevacoin is DIFFERENT. We hope its value is truly based on its usefulness.

Looks like virustotal gives now 0 detection details on the windows wallet. Good job!

https://www.virustotal.com/gui/file/4a5e880b961697b00041aff9f5fdd61059c54889700a3c6c4bb38b4c20a3b7ed/detection

I will install the wallet and mine some coins.

As tip: for new users to mine easy I would suggest to add this to the mining pool - "getting started" page

<miner.exe -a cnr -o stratum+tcp://stratum.kevapool.com:3333 -u [WALLET] -p [ANY]>

P.S. some miner links will also be very useful.

We are glad that you are excited about Kevacoin!
It is our goal to make Kevacoin "People's Coin"  Smiley We want to make it easy for everyone to use and mine. We don't have a video tutorial, but our Discord community has a mining channel.
Solo mining needs a little bit more work than mining pool but it can be managed. You need three pieces of software:

1. Wallet
2. Miner
3. Keva Stratum server

You can check out our stratum server site to see if that helps you:

Very good, thank you!
This will help newcomers in the way that they will find the mining tools much faster and get involved in the mining process without being forced to Google for miners.

I am mining using "XMR-AEON-STAK-2.10.4-CNv4-cnR". I don't know if this is the best for my Nvidia cards, but I will give it a try with the miner posted by you and will come back with some feedback.

The presentation will be added to a block on January 25, 2020, around 3:30pm GMT, 11:30pm CST (China Standard Time).

A Chinese name is necessary because the language does not have an alphabet. Please contact us and make a suggestion if a name is required for your language  Smiley

}

We are experiencing a sudden increase of network hash rate. Kevacoin's difficulty retargeting algorithm seems to work as expected, as the average block time is still about 2 minutes (last time I checked).
In case of a sudden decrease of network hash rate, the retargeting algorithm shall adjust downward even faster, allowing other miners to catch up.

v0.16.3.1 Release

This is the first release after the Mainnet launch. It is an important release for developers and mining pool operators and is strongly recommended for these users.

For Mining Pool Operators
Added new RPC getblockheaderbyhash.

For Developers
Added ZeroMQ notification for Keva events (keva_namespace, keva_update, keva_delete). See Kevacoin ZeroMQ(https://github.com/kevacoin-project/kevacoin/blob/master/doc/zmq.md). This should make it much easier to develop on Kevacoin's blockchain data store.
Added new RPC getzmqnotifications.

Minor Changes
Applied Kevacoin's Chinese name.
Updated documentation.

To build a strong community you will need to engage more people into the project. For this you need to run a bounty campaign on twitter, facebook, linkedin, instagram to make some noise out there and create awareness so more people will come in here and use the platform. At least this is how I would proceed if it was my project.

To Buy, or not to Sell? That is the question.

We are a fair-launch PoW coin, so as Dev we earn coins through mining, just like anyone else. However, we do have several big dudes who have more coins that most of us. We will try to encourage them to contribute to the bounty campaign  Wink

what particular decentralized apps are you looking for Keva to venture with? it is really better to have practical use case in crypto market to have a steady growth rather than focusing in listing this to exchanges. 1 or 2 exchanges later is more than enough, but creating value should be the main focus. because without active application, the platform will die down easily and will be dead just like thousands of alts.

Yes, encouraging more developers to develop on our platform is our main focus. We feel that we should promote our platform on ProductHunt, Hacker News, etc, where there are more developers.

But everyone can start using the platform now! Here is an easy way to develop on our platform, publishing a website:
https://explorer.kevacoin.org/ns/html/NceXtbgQD92zrVM7QUnfNhrRcj2DQ1PewD

The tutorial above is published on our platform, by the way  Smiley Our explorer can render the web page (with less than 30 lines of code), and anyone can write a simple program to render it too!

A while ago we published a Chinese new year celebration page:
https://explorer.kevacoin.org/ns/html/NVWKk9edEw9K8MRGySwkHx7AWoCUTKDKRF

It is completely possible to develop a Twitter-like app on our platform, also forum apps (maybe a decentralized forum for the crypto community  Smiley). We will showcase some apps later, but it is not hard to start using our platform if you know a little bit about programming!

Anytime!

I know Keva had a fair launch with no premine, and this is a pullback because you lack funding.

You can set a donation fund for this kind of actions, like bounties, exchange listings, other expenses. People will put some money in because is their interest to grow the project and see the price going up.

To Buy, or not to Sell? That is the question.

Thanks for your advice. We will start a discussion on our discord community on how to set up and manage the donation fund. We believe it is better for the community to manage the fund. We can make recommendations on how to spend it, but the community should have the final saying.

Good move @calmstorm and I believe you are right about who should manage the community donation funds, since they are the ones who donates and of course for more transparency.

We have a community fund to support the development and promotion of Kevacoin. The fund can be used for:

1. Bounty campaign.
2. Give-away to developers to try out the platform.
3. Future exchange listing.
4. etc.

The fund belongs to the community, and its management is transparent. We currently only take Kevacoin and please send your donation to this address:
VE6Q8bpn8gRKRoWXFPXMPFZt6juXYyNbe1

Once you give a donation to the above address, please send a note to this channel to let us know (you can stay anonymous if you wish so :grinning: ). Every time we take KVA from the fund, we will also notice the community through this channel.

You can see the transaction of the fund here:
https://explorer.kevacoin.org/address/VE6Q8bpn8gRKRoWXFPXMPFZt6juXYyNbe1

Suggestions and comments about the management of the fund are welcomed!

We just donated 100 KVA to kickstart the community fund!

You can set a donation fund for this kind of actions, like bounties, exchange listings, other expenses. People will put some money in because is their interest to grow the project and see the price going up.

Thanks for your advice. We will start a discussion on our discord community on how to set up and manage the donation fund. We believe it is better for the community to manage the fund. We can make recommendations on how to spend it, but the community should have the final saying.


Good move @calmstorm and I believe you are right about who should manage the community donation funds, since they are the ones who donates and of course for more transparency.
I also agreed that who will be authority to manage the community donation fund as they are the person who donates with more clearity.

Dev, so has it really been decided that there will be an algo change? If so, then when, and to what algo? I think that the community should have a part in these decisions - like if you do decide to switch the algo - you could let the community vote on it. A new / modified algo for KVA would also be cool (assuming that your team is capable of making such, since you plan to develop a blockchain for Key-Value data storage Wink).

A nicehash/asic,even GPU mining-resistent algo would be better imo. CPU only is the best.
Since I don't like, and is also too centralized the ninja mining/cloud mining all over other projects, this will be the best move for Keva.

To Buy, or not to Sell? That is the question.

Thanks for the suggestions and I apologize for lack of communication on this important issue. The main reason is that we are still struggling with what is the best move for the next step. We originally plan to use our slightly tweaked version of Cryptnoght R (and call it Cryptonight KV). However, that would require us to submit patches to various miners (e.g. XMRig, XMR-stak, T-rex, etc.). Since CN/R is a GPU/CPU algorithm, we need to implement support AMD, NVIDIA and CPU. It is quite a lot of work and uncertainty (not sure if the miners would accept our patches and they are moving to CPU-only RandomX). Then Kevacoin source code will need lots of changes. Unlike Monero source code, which is designed with hard-forks in mind, the Keva source code does not have support for hard-fork and we need to implement and test it. This is lot of work and testing. Honestly, we are secretly hoping that Nicehash's support for CN/R will go away, just like other older CN algorithms. We had a glimmer of hope this morning as the available hash rate of CN/R dropped to 1MHz (from 6 MHz) on the US market for a while.

However, we do agree that the CPU only is the future, and it fits our targeted developer demography, as these people normally have machines with powerful CPUs but only average GPUs. The recent development of AMD multi-core CPUs also makes CPU mining very promising. Our concern is that some of our early supporters are GPU miners and we don't want to disappoint them. But it is a fact that CPU mining is good for the long term for Kevacoin.

We will have a vote on the switch as suggested. Comments and suggestions are welcomed!

One thing that you can do, to not disappoint the early GPU miners is to premine the existing coins on the new blockchain and swap them for old coins so they won't loose the coins mined. Then  they can continue to mine Keva like other if they want to stick to the project. This is how I would do it, as I think you can't simply switch to new mining algo, but rather launch a new blockchain.

To Buy, or not to Sell? That is the question.

Fortunately, we will be able to do a hard-fork and keep the original chain. So the GPU miners will keep their coins.

We are communicating with stakeholders, and have made great progress. We have important pieces ready and starting from this week, we will communicate with the rest of the stakeholders and finalize the date. Hopefully, we can let the community know the exact fork date this week. Thank you again for your patience and please stay tuned!

Any info about the fork? Algo change, blockchain timing /reward change other changes?
What is the reason for the fork? Which pools will support it? Is it going to be CPU only or also GPU/ASIC?

v0.16.4 Release
=====================================

Mandatory Upgrade

This is a major release of Kevacoin software, upgrade to this release is mandatory due to the hard fork on March 25, 2020. The hard fork will switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.

Before upgrading to this version, make sure to back up your wallet in case something unexpected happens, even though this release should not affect your wallet. Uninstall the previous version and install this version.

Important changes in this release:

- Switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.
- Faster wallet synchronization.

Download the wallet from our website:

Hi admin kevacoin, if the test net already running, can we mine keva coin on the test net ?
Have you released the miner of kevacoin with random-keva algo ?
I would like to test mining with random-keva algo miners.

Hi admin kevacoin, if the test net already running, can we mine keva coin on the test net ?
Have you released the miner of kevacoin with random-keva algo ?
I would like to test mining with random-keva algo miners.

The following miners support rx/keva:

xmrigCC 2.6.1: https://github.com/Bendr0id/xmrigCC/releases/tag/2.6.2
xmrig 5.9.0: https://github.com/xmrig/xmrig/releases/tag/v5.9.0
SRBMiner-Multi 0.4.0: https://github.com/doktor83/SRBMiner-Multi/releases/tag/0.4.0

You can mine Kevacoin on testnet. Please download the latest v0.16.5 wallet from https://kevacoin.org.
(Do not use v0.16.4, it contains a critical bug)

We have a test mining pool too:

149.56.12.57:3333
149.56.12.57:5555
149.56.12.57:7777

Please feel free to let me know if you have any questions.

Very nice, i guess i will using xmrig 5.9.0 to mining from my computers.
What are the difficulties of the ports ? port 3333 is for the low end hardware isn't it ? my computer cpu is not too high.
Thank you for your previous explanation.

Thank you for your previous explanation.

Right, port 3333 is for low-end hardware with the initial difficulty of 8000. The mining pool will adjust the difficulty according to the actual hashrate of your hardware. It will increase the difficulty if the hardware has higher hashrate, while it will decrease the difficulty if it has lower actual hashrate.

Here are the description of the test mining pool:

      "port": 3333,
      "difficulty": 8000,
      "desc": "Low end hardware"

      "port": 5555,
      "difficulty": 16000,
      "desc": "Mid range hardware"

      "port": 7777,
      "difficulty": 32000,

v0.16.5 Release - Mandatory Upgrade

Note: Previous release v0.16.4 contains critical issues. Do not use!

This is a major release of Kevacoin software, upgrade to this release is mandatory due to the hard fork on March 25, 2020. The hard fork will switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.

Before upgrading to this version, make sure to back up your wallet in case something unexpected happens. Uninstall the previous version and install this version.

Important changes in this release:

- Switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.
- Faster wallet synchronization.
- Fixed Initial Block Download (IBD) with RandomKeva. Added new data structure to store the hashes at different seed height.
- Disable miner mode of RandomKeva hash function. The miner mode causes incorrect results when the seed height changes, due to the incorrect initialization of the RandomX VM.

We are experiencing a sudden increase in hash rate after the algorithm change. Our original hope was that we could have a period of organic growth after the switch, but apparently this is not the case now.

Here are what we suggest:

1. For the miners, if possible, please try to distribute your hash rate among different ming pools. The goal is to make our blockchain as decentralized as possible.
2. For developers, if you have difficulty getting the coins (KVA) to test the platform, please feel free to let us know. We have a community fund to support the developers.

If you have any suggestions and concerns, please feel free to let the community and us know.

Well hopefully these are distributed miners, and it would be cool if some of the miners switch over to the other pools to distribute the network hashrate. Otherwise, I'm pretty happy that so many new people have jumped on board.

If we see the network hash rate of the coin in : https://miningpoolstats.stream/kevacoin ,
the most hash rate is on lepool, about 70% network hash rate.
im gonna mining the coin on other pool to distribute the hash rate, hashvault maybe the good choice.

Does Keva have a real-world use case?

Why should people prefer it?

Does Keva have a real-world use case?
How it is better from other crypto currencies?
Why should people prefer it?

Yes!  In an extremely simple example, anyone can easily write messages in the KVA blockchain. Yes, BTC can do that too, but KVA has the builtin commands to do that. What is more, KVA is a structural database, you can easily find the message you post, update it, delete it (the history will still be there though).

Database is the foundation of modern internet applications. For the first time, KVA implements a database that is open to everyone, not owned by anyone, secure and trusted. Using KVA database does not require smart contract, any programming languages will do. And unlike smart contract, which is very difficult to implement and validate, with KVA database, the applications are easy to implement and easy to update.

Any applications that require a database that is not owned by anyone, yet is open to everyone should consider using KVA. Example, public identity system, public service messages, public notary system, coordination between federated social network instances (e.g. Mastodon). It can essentially be used as a "glue" of the decentralized web.

And it is available TODAY. Read the simple documentation, and you are ready to take advantage of it.



Also among the Bitcoin derived coins, Kevacoin likely has the most CPU friendly mining algorithm - significantly faster than any GPUs. So fire up your PC and start mining  Wink



KVA will debut on KuangEx.com with KVA/USDT pair!

https://twitter.com/kuangex/status/1245555292403687425

KuangEx.com is a new crypto exchange found on Oct. 1, 2019. The website is currently Chinese only, but their representative told us that it will soon have an English version.




Thanks DxPool for the donation to our community fund!

Dxpool Will Donate 50% of Pool Fee to Kavacoin's Community Fund for the Next 3 Months

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.

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.

Keva uses a variant of RandomX called RandomKeva. It is about 5 - 10% faster than RandomX due to its use of smaller scratchpad.
You can find out the hashrates of various CPUs here for RandomX:

https://monerobenchmarks.info/

Please note that with RandomX and RandomKeva, CPU normally has a big advantage over GPU. So you should consider mining with CPU.

v0.16.5.2 Release

This release adds the bookmarking of Kevacoin namespaces. You can now add, edit, or remove namespaces from your bookmarks through the Kevacoin core GUI. Use the namespaces as IP addresses!

Other fixes:

1. Fixed a potential race condition during block syncing. This fix is a precaution as it is unlikely the race condition would happen.
2. Fixed namespace table view on macOS.

You can also download the Android wallet app from Google Play Store:

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.

FYI: Apple App Store has approved Kevacoin Mobile Wallet 5.8.1.

We are about to release 5.9.1 soon - this version will significantly reduce the data required from the server and make refreshing much faster. We would like to thank our users for giving us valuable feedback.

So far we have been working on stabilizing and optimizing the mobile wallets. Now we are at the point that we feel comfortable to start adding Keva-related features on the mobile wallet. You will start to see big UI changes to our mobile wallets.

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.

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.

v0.16.6.0 Security Update

This is an important security update that fixes namespace creation vulnerabilities. The fixes are implemented as a BIP9 soft fork and was activated since block 129600.
https://github.com/kevacoin-project/kevacoin/releases/tag/v0.16.6.0

Target Audience

Mining pools
If you are already using the secret v0.16.5.4 release, you can safely skip this release.

Full nodes
Although not required since this is a soft fork, it is strongly recommended that you upgrade your public full nodes.

Exchanges
Although not required since this is a soft fork, it is strongly recommended that you upgrade your nodes.

Developers
This is a mandatory upgrade if you want to create a new namespace. The older version of Kevacoin core will not be able to create namespaces that will be accepted by the miners.

New Features
This release introduces the namespace group feature, which allows the combination of the namespaces. We will release the documentation and tutorial for this new feature soon.

We will update the official ElectrumX servers at 15:00 UTC, on Saturday, Sept. 5. The update will last about two to three hours. During this time, the servers will be unavailable and the mobile wallet cannot be used. Sorry for the inconvenience.

If you run your own server, please download the latest ElectrumX server code and upgrade your server as soon as possible:

iOS KevaWallet 6.5.2 Available on App Store

iOS KevaWallet 6.5.2 is live on Apple App Store. Upgrade to this version (6.5.2) is strongly recommended for all iOS KevaWallet users, as it addresses a critical issue ("Error writing saving keys") when the number of transactions exceeds a certain limit.

This release also brings the feature set of iOS on par with the Android one. You will now be able to access the Keva blockchain database from the iOS mobile app. You can post, reply, and reward other posts.

Since this is a major upgrade, please make sure to backup your wallet before upgrading.

Keva and IPFS on Mobile Devices

Our latest blog:
https://kevacoin.org/ipfs_mobile.html

You can write your blogs in plain text or HTML, and you can insert pictures and videos. However, the pictures and the videos must be hosted on a server somewhere, and you have to insert the HTTP links. It is not an ideal decentralized solution and we are working on a solution that will allow you to upload your pictures and videos to IPFS from your mobile device. Integrating IPFS in a mobile app is an interesting challenge. The major problem is that mobile apps cannot have constant network connection (otherwise the battery will quickly drain), and reliable network connection (WIFI vs cellular data). Because of this, after you upload an image or video to IPFS, other people may not be able to access the file if your mobile app is not connected to the internet. Running an IPFS peer on a mobile device will also have performance issues. An IPFS peer opens many connections to other peers and requires large network bandwidth and CPU cycles, which may not be suitable for a mobile device.

Check out our proposal on our latest blog: https://kevacoin.org/ipfs_mobile.html

Need some Kevacoin (KVA) for testing?

We believe that everyone should be able to access the Keva decentralized database. Now we make it easier for you to give it a try!

For a limited time, we will give away 10 KVA for you to try our blockchain database. You need a Twitter account and a Kevacoin wallet.

If you don't have a Kevacoin wallet:

1. Download the iOS or Android Kevacoin wallet (https://kevacoin.org)
2. Create a wallet, go into the wallet, tap "Receive" to get a new Kevacoin address (e.g. VVtR26gk....).
3. Tap the address to copy it to the clipboard.
4. Send a direct message to @kevacoin with the address from your Twitter account.

You should receive 10 KVA Kevacoin (subject to change) in about two minutes. Simply pull down to refresh in your Kevacoin wallet.

With the Kevacoins, you can start posting on the blockchain. Have fun!

Hello there!
Sorry for my dumb question, since I didn't followed the project closely, but are those 10 KVA coins the real deal, I mean, mainnet KVA coins or are testnet coins?
Thank you!

To Buy, or not to Sell? That is the question.

Thank you!

It is the real deal  Smiley they are the mainnet KVA coins. You can simply download the Android or iOS mobile app to quickly get an address. With the KVA, you can read and write to the mainnet blockchain database from your mobile devices.
If you don't have a Twitter account, please feel free to send us a PM in discord: https://discord.gg/5zPHhbG (Twitter will be faster because it is handled automatically by a server).

I'm not a fan of mobile wallets but I will give it a try if you don't have desktop wallets. As for the Twitter, sure I have. I'll send you a message as soon as I'll have the wallet installed.

v0.16.7.0 Release

New features in this release:

1. The keva_put command has a new option to transfer the namespace to an address:

Code:
kevacoin-cli keva_put NgKBKkBAJMtzsuit85TpTpo5Xj6UQUg1wr a_key a_value VXv2qSNoVKcwZLPxf28z92VvBfERbFx3Kq


   The above command puts a_value to a_key and at the same time, transfers the namespace to the address VXv2qSNoVKcwZLPxf28z92VvBfERbFx3Kq. The address can be any valid address, it can be your address in a different wallet (e.g. mobile wallet), or other people's address. If the new address is in a different wallet than your current one, you will no longer be able to modify the namespace from your current wallet.

2. The desktop GUI wallet now displays correctly the download progress (in percentage) and the estimate of the remaining time for the download to complete.

During this release, we also ran static analysis tools on the source code and fixed the found issues and warnings.

Download it here:
https://github.com/kevacoin-project/kevacoin/releases/tag/v0.16.7.0

Some important things to remember for Keva's blogging platform:

1. It doesn't require centralized servers. Anyone can run a server and get EXACTLY the same content as other servers. In other words, there is no single point of failures. Here is how to run your server: https://kevacoin.org/keva_electrumx.html Once you have your own server, point your wallet to the server.
2. We will make it much easier to run your server by using Docker image, which could allow "one-click" installation.
3. We need to be transparent with you that the current Keva app is not 100% production-ready. We need additional work on the server (and some corresponding work on App) to make it scale to more users and more messages. The changes are not difficult to implement, and we will try our best to complete them ASAP.

Thanks for using Keva App!

Again, thanks for using Kevacoin wallet!

If you host your own ElectrumX server, please upgrade it to the latest version. You need to resync the database.

Keva is simply the most usable crypto in the World.

1. Real world use cases - with actual current development - mobile wallet micro blogging and "twitter" already working great. Public sector applications being developed now!!!
2. Games - Play Legend of Satoshi and earn Keva and Raven coins
3. NFT's - Easier, cheaper and better than Ethereum and the alternatives
4. Active development with consistently updated and upgraded wallets and security
5. no premine or ico or any nonsense that is getting some other coins in trouble

It is really fun working on the enterprise application with Keva blockchain as database. In the enterprise application, application servers are "cattle", while database is "pet". You can always kill the application server and start a new one. But you need to take very good care of the database. Database is expensive to maintain and backup, your business  is gone when the database is gone. With keva blockchain database, the database becomes the last thing to worry about. It will even survive a nuclear attack  On top of that, Keva is most likely the easiest blockchain database to use - it is designed for that purpose!

Hello there!

I was so inspired by Kevacoin Project so writing KVAZAR - Open Source Content Exploring Platform for Kevacoin Blockchain.
Content still indexing but everyone already able to enjoy the beta. The platform skips the blocks without data and shows only human readable content in the time line.

Hope, the service will be interesting for kva namespace finders and web-3.0 lovers!

Website:
https://kvazar.ml

The project:

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 simil
