A reminder to all miners still on 0.11 to upgrade to 0.12.

About 80% of the newly mined blocks are on 0.12. 95% is required for activation of the 0.12 soft forks.

Thank you to those who have already upgraded.

Release - Zetacoin 0.11.3.4

With more than 70% of nodes now on v0.11.3.2 or later (according to cryptoID) we can proceed with the last update to complete the v0.11 soft forks.

Blocks mined by this release will mine version 5 blocks. When 95% of 10,000 blocks mined are version 5 blocks, version 3 blocks will no longer be allowed and may cause old wallets/miners to split off the network.

This is a required upgrade for miners. Pool operators, please ensure your block header version is 5.

Optional upgrade for wallet users on v0.11.3.2 or higher.

If you are on v0.11.3.1 or lower, this is a required upgrade.

See the first post for download links or find them under the Github release here:

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.3.4

Zetacoin 0.11.3.3

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.3.3

Enforce BIP65 CHECKLOCKTIMEVERIFY (Block version 4)

Required upgrade for miners.

Other wallets required to be on 0.11.3.1 or later (0.11.3.2 recommended).

Note to pools: Please ensure you are mining version 4 blocks.

Zetacoin 0.11.3.2

Download wallets from here:

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.3.2

- Prepare for soft fork version 5 blocks that rejects non-CLTV (v3) blocks
- Required update

This release is a required update for wallets for activating DER and CLTV.
The next two releases to complete the DER and CLTV activation will be for miners and will be released when enough wallets have upgraded.

There are people incorrectly mining with other software/pools that sets version bits. These are detected as > 3 blocks.

If you mine with the wallet it will only generate version 3 blocks.

There were no changes that should affect performance.

The only effective change is that version 2 blocks will be rejected once 95% blocks are on version 4. Blocks are on version 3, so this code is not effective yet.

The next release will increase the block version to 4.

Zetacoin 0.11.3.1 (required upgrade)

- Fix soft fork parameters
- Prepare for BIP65 (CHECKLOCKTIMEVERIFY) activation
- Checkpoint

Downloads for Windows and OSX available here:

The last major code update was a few months ago to the features of Bitcoin Core 0.11.

The next major update will probably be to the features of Bitcoin Core 0.12. After that we'll see which code base to follow with Bitcoin Core/Classic/Unlimited/Fork going in different directions.

Zetacoin has always tried to remain close to the Bitcoin code base (except for the quicker coin distribution and shorter block times).

The official web site is http://www.zetac.org/

The latest version is 0.11.2.3. You can find it on the web site or on github:

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.2.3

Updated OSX build available as part of the 0.11.2.3 release:

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.2.3

Of course. The code base was recently upgraded to be on par with Bitcoin 0.11.2 and the chain just reached 5 million blocks!

The daemon uses around 1 GB on my seed node. It hasn't been able to run on 512MB for a while now.

This appears normal for almost 5 million blocks in the chain. This is similar to other coins that has 2+ years of blockchain data.

Thanks rossen.

I would encourage everyone to upgrade to 0.11.2.2. Once enough nodes have upgraded a new version will be released to start enforcing version 3 blocks.

Note that the format of rpcallowip address in your configuration has changed between 0.9 and 0.11.

e.g. previously you would have something like:

rpcallowip=192.168.1.*

now you have to include the subnet, e.g.

rpcallowip=192.168.1.0/24

Zetacoin 0.11.2.2 released

This is a required/immediate update for 0.11.2.1 users

0.9 users, please update as soon as possible

https://github.com/zetacoin/zetacoin/releases/tag/v0.11.2.2

Notes:
Due to 950 of 1000 being blocks being mined with v3 blocks (0.11.2.1), 0.11.2.1 nodes started rejecting v2 blocks. This caused the 0.11.2.1 nodes and 0.9 nodes to be on different forks. This soft fork obviously happened too fast, as most nodes are still on 0.9.

0.11.2.2 has been released to not reject v2 blocks, so it will be on the same chain as v0.9 nodes.


Edit:

Coinplorer appears to be on the correct (longest) chain.

https://coinplorer.com/ZET/

Yes, unfortunately it happened too quickly. The majority of nodes have not upgraded leaving the 0.11.2.1 users on a shorter chain.

A new release is being prepared where the consensus rule in 0.11.2.1 is disabled to allow 0.11 nodes to get back on the longest chain.

Edit:

Correct chain block 4874191 hash 000000000001d08ec451b8b71be3a8cbe6ad6480da6bc46c600a2d4f537c9172

With 90% of blocks mined with version 0.11.2, the new version now is now required.

Please update to version 0.11.2 as soon as possible if you have not yet.
