Great to hear you still running Crown nodes Daniel 

By the way, the timestamping part of code you implemented from Namecoin was the base idea for our upcoming NFT's release

Awesome explanation of Crown MNPoS by Mark

‼️MANDATORY $CRW UPDATE‼️

Please update your #masternodes and #systemnodes to v0.13.2.0 which fixes the difficulty adjustment problem.

Release is ready - https://github.com/Crowndev/crown-core/releases/tag/v0.13.2.0

This is the command to update
sudo apt-get install curl -y && curl -s https://raw.githubusercontent.com/Crowndev/crowncoin/master/scripts/crown-server-install.sh | bash -s

https://twitter.com/CrownPlatform

The $CRW blockchain is stalled on the last #PoW block: 2.329.999. A new release is being prepared with readjusted difficulty, so that the MN/SN network can generate the first #MNPoS block. Stay tuned.

Same situation here. Didn't check the masternode yet, don't have access to it from where I am at the moment.

My nodes (running version v0.13.0) are stuck on block 2,329,999.  Is this a known bug or just me?

Dam didnt realize btcforum wasnt a social network  , learn new things everyday hey.

PLz advise holders when stable new wallet is out..

1st did the exchanges get contacted about new update.

How much testing has been done to make sure new wallet is stable?
Whats is been done to inc CRW  btc value and minimize supply over time? Its basic Demand vs Supply
U cant lose yourself in thinking a value of a coin is just its masternodes and system nodes value, whats the value/USe of a CRW coin to use bar that then?

With mn vote system the MN voters should vote to have  more clean system that will get them better returns over time.
Maybe a more structured vote system with different areas to vote on with different values and end returns for ALL crw holders.
EG. TECH GROWTH/PROMO/DEV/DONATIONS/BURNS .....
All bar the dev tab should be open vote but the dev tab votes should only be able by non devs masternodes and proved as such.
Self voting on ur pay rises isnt good karma.


I know i know im always here laying down the big ?s but some 1 g2 do it.

Hello CRW Community,

Just wanted to put this out there. I updated an old Wallet to the new Version 0.13.0.0. I was trying to shuffle some coins around and discovered I can't transfer coins to the exchanges. I know the old wallet can't send to new, the new can't send to old. I tried both ways on two exchanges and both say invalid. I contacted both exchanges Bittrex and Thecoin.pw assuming they need to update there wallets. Not sure what Bittrex expected me to do since the reply sounds like they are throwing the ball back at me?

The reply from Bittrex was this.
Good Afternoon,

After further review, it looks like the best way to resolve the issue for your wallets would be to contact the wallet developers, they may have information on how to fix this issue.

Thank you for contacting the Bittrex Customer Experience Team. I hope you have a wonderful day and a great rest of your week.
Best Regards,

Lulu Jerico @ Bittrex
Follow us on Twitter @ https[Suspicious link removed]xchange

The Reply from Thecoin.pw was this.
Thanks for letting me know.

I wanted to let you know that we are currently investigating this issue. It appears there is a problem with the wallet, we are working with the coin developers to correct the issue.

I'll keep you updated.

Regards
Glen

Hope this helps some of you until all the new wallets get figures out.

Thanks

Crown Masternode and Sytemnode Proof of Stake Consensus System [MNPoS]

CROWN RELEASES JADE - AN UNIQUE ALL NODE STAKING POS PROTOCOL

Crown Core “Jade” v0.13.0 Mandatory Update

Release notes, update instructions, MNPoS, CRW prefixes explanation

Jade v0.13.0 launches the new Masternode Proof of Stake [MNPoS] consensus system. MNPoS will kick in 2 weeks after the release, at block height 2.330.000. The network has time to update to v0.13.0 until block height 2.327.000. Old nodes will be cut off at 2.327.000. v0.13.0 also includes unique CRW prefixes. Once you update your client to v0.13.0 all your public addresses will automatically be converted to new ones with CRW prefixes. You can read more about CRW prefixes in the technical documentation of Crown Platform, chapter 5.3 or in Mark Brooker’s release notes on GitLab.

Crown Jade is live on mainnet
If you are reading this, Crown has successfully released Crown Core v0.13.0. I have provided a fast read with the release notes and update instructions, followed by informations on the CRW prefixes, MNPoS, block reward changes and next development milestones.

What’s next

1. Release Notes

Crown Core Jade v0.13.0 features 2 main changes over the previous v0.12.5.x version.
a) Switch from Proof of Work to Proof of Stake
b) New [CRW] address prefixes

A total of 158 commits have been in place to make this release possible. The starring devs for this release have been Presstab (70 commits) as creator of the custom MNPoS solution and Ashot (62 commits) as Crown Core lead and supervisor. This shows an impressive engagement and coordination with a total of 6 developers involved in developing Jade. A massive shout out to defunctec and walkjivefly, who have been involved in testing during months!
The full release notes are available on Gitlab, courtesy of Mark Brooker.

2. Update instructions
Protocol version is changed to 70055. This release is mandatory for the whole network. Please always back up your wallet.dat before proceeding to update the client.
Crown QT will prompt for update.


CRW wallets can be downloaded for free using the links provided below.
https://crown.tech/wallet/

Core of Crown blockchain platform. Contribution repository is available by this link…
github.com   

To update masternodes/systemnodes/other crownd instances use the following script:

sudo apt-get install curl -y && curl -s https://raw.githubusercontent.com/Crowndev/crowncoin/master/scripts/crown-server-install.sh | bash -s

3. CRW unique addresses

When Crown originally forked from Bitcoin it retained the Bitcoin address format. Nowadays that is not a desirable legacy because it prevents use of Crown with hardware wallets such as Ledger and Trezor. Those devices cannot distinguish between different coins with the same address prefixes.
v0.13.0 introduces new prefixes for both mainnet and testnet.

Mainnet addresses now begin with the prefix “CRW”, eg:CRWP934B9FbM5RaTUfT7zCH12a259j4PYbSE
Testnet addresses now begin with the prefix “tCRW”, eg:tCRWZpkQ8aJ4wyWx5MiZup23WG8aw5JmKRAaQ

These unique and distinctive prefixes will enable the use of Crown with hardware wallets. We hope to see the first integration soon.
The change is largely friction-free from the user’s perspective. Once users update to v 0.13.0, they will be able to receive CRW sent to old addresses from old wallets.

New wallets cannot send CRW to an old address.
Old wallets cannot send CRW to a new address.

If an updated wallet wants to send any amount of CRW to the old address it needs to be converted via Crown command line. For example:
crown-cli convertaddress 15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L
Result CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF
If the equivalent new address of 15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L is CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF you can send CRW from the old wallet (v 0.12.5.3) using 15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L and from new one (v 0.13.0) using CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF.

Both old and new wallets will be able to see the CRW!

4. MNPoS
On 18th of July 2018, Crown announced that it had signed an agreement with Paddington Software Services to develop and implement a custom Masternode and Systemnode Proof of Stake consensus algorithm on Crown Core. Eight months later and due to a huge community effort funding, monitoring and testing the solution, the code is now ready and included in the Jade 0.13.0 release. At block height 2.330.000, on April 12th approximately, the first Proof of Stake block will be minted by either a Master- or a Systemnode, and the transition from auxpow to MNPoS will be complete.

   
5. Why is the Crown MNPoS system unique?

It has been much argued if and why the new consensus system is unique. There are many reasons. Presstab has solved the disclosed vulnerabilities that affected some conventional PoS systems and has used the Masternode network as an additional dimension of security. I have published an additional article with contents authored by press tab and Mark Brooker containing the technical specifications of the MNPoS consensus system:
Crown Masternode and Sytemnode Proof of Stake Consensus System [MNPoS]


6. Block rewards after MNPoS

The block reward distribution will change at block height 2.330.000, when MNPoS kicks in. This graphic explains the changes.

On the left, reward distribution with PoW. On the right, reward distribution with MNPoS — starting at block height 2.330.000.

6. What’s next

Jade is a huge milestone for the Crown project, but this is just the first of a series of releases that will lead to Crown Platform v1.0. The next release “Emerald” is just around the corner and will feature the Non-Fungible Token [NFT] framework. NFTs on Crown Platform are a functionality with unique charateristics designed and implemented by Artem. More information about NFTs on Crown Platform will be available during April.


Thank you for your continued support of the Crown project!

Because I did not fully understand the upcoming JADE release, I asked the discord what would change.

Since there will be no more miners, masternode and systemnode operators will receive staking rewards in ADDITION to the CRW payouts.

I think it's really unique in that form.

Tomorrow a release article will be published explaining everything.

Proof of Work will continue until block height 2.330.000. At this height, the first Proof of Stake block will be created

Old nodes will be cut off at height 2.327.000

Old and new prefixes will work from March 28th on updated clients

The new version will be released on March 28th and the Proof of Stake switch will happen at block height 2.330.000 (approx. 2 weeks later)
We are extremely happy to announce that the Master- and Systemnode Proof of Stake solution is ready to be launched. Crown Jade (v0.13.0) also includes the release of unique CRW addresses.

Dates and block height
Crown Jade will be released on March 28th. From this moment on, clients can be updated to the new version. The network will have two weeks to update to v0.13.0. At block height 2.327.000, old nodes will be cut off. 3000 Blocks later, at height 2.330.000, the first Proof of Stake block will be produced. Block 2.330.000 is estimated to kick in between 11th and 12th of April.

Miners
Miners please take into account that after the Proof of Stake switch is completed, Proof of Work will cease to function on Crown Core. We sincerely thank you for securing the Crown network during these years and hope to keep you on board as PoS minters.

unique CRW address prefixes
Once users update to v 0.13.0, they will be able to receive CRW sent to old addresses from old wallets.
New wallets cannot send CRW to an old address.
Old wallets cannot send CRW to a new address.
If an updated wallet wants to send any amount of CRW to the old address it needs to be converted via Crown command line. For example:
crown-cli convertaddress 15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L Result CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF
If the equivalent new address of ‘15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L’ is
‘CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF’
you can send CRW from the old wallet (v 0.12.5.3) using ‘15bj2HB2UbmjEZgXyEW4M8MhUL5TXGCN8L’
and from new one (v 0.13.0) using ‘CRWGZiLqSUbCTWkm3ABp5qpXdun2h8DJCKYF’
Both old and new wallets will receive the CRW!
Unique CRW addresses will allow for future hardware wallet integrations such as Trezor and Ledger, a long awaited functionality.

Exchanges
Exchanges will update to the new version during the transition period. Please double check that you are using the correct address to deposit funds and do not hesitate to ask us or the exchanges questions. Security of the network and funds is number one priority and will be guaranteed during the entire process. Nevertheless, we recommend users to always do a test send first during this period to ensure that funds are being displayed in the interface of the exchanges.

Support
Feel free to ask any questions on Discord or Telegram. The recommended channel is Discord, you can join using this link: https://discord.gg/KCRFF4

Major Milestone
Jade represents a major milestone that has been in the works for almost a year, since we first contacted Presstab and his team at Paddington Solutions. Crown Community is responsible for this success, since it has been supportive all the way from crowdfunding to patiently awaiting development, testing, and vulnerability fix of this unique and custom solution that puts the Crown project at the avant-garde of blockchain consensus algorithms.
Thank you, Crown Community! Thank you Ashot, Artem, and Presstab!

Check out the thread for a digest!

Your words sound like you have good experience with the platform and their team.
It is a potentially reliable platform based on your remarks.
So, I will try experiecing this one by myself and see how good it is.

Sure its a young platform, but we have met with them personally (as we usually do) and they are good guys. Up to the potential users to make a decision if its a useful service or not I dont trade so I dont know

Yanda has still been a young platform, and I could not find it on coinmarketcap.
In the article, I found that there are 50% discount for users who use CROWN as payment gate, for only the first 500 users.
After that, the discount rate will turn to only 10%.
