[ANN] Terracoin (TRC) - Est 2012

[adorid]

i got the same problem with merged option.

TestBlockValidity: Consensus::ContextualCheckBlockHeader: late-legacy-block (code 16)

[hanzac]

If you use p2pool, should add command param --merged. Otherwise, it will still use getblocktemplate.

i do use "--merged". it calls getauxblock and has still problems! other merged coins work fine! only TRC has problems.

p2pool (version 16.0-4-gde1be30-dirty)

Can you post your error log?

[hanzac]

Does it mean that after merged mining started, the p2pool server for terracoin is not needed.
Only you run the p2pool server for bitcoin, and add --merged http://user:pass@terracoin_rpc_host:terracoin_rpc_port
Then it will start merge mining the terracoin.
You can check this guide: https://bitcointalk.org/index.php?topic=62842.0

my wallet doesnt accept new block... and even with merged mining:

p2pool.util.jsonrpc.NarrowError: -1 CreateNewBlock: TestBlockValidity failed: late-legacy-block (code 16)

It seems that we need ahmedbodi/TRC dev team to fix it, it seems that CreateNewBlock method rejects its own created block.

Mork TRC calling Ahmed - come in Ahmed......

[clockuniverse]

I went to bed and all hell broke loose!!

I emailed Ahmed yesterday afternoon to warn him the hard fork was coming, and I just now opened an issue.

https://github.com/clockuniverse/terracoin/issues/6

I will also email him again.  Don't worry we will get it fixed!!

[clockuniverse]

Don't stress if you have lost 3 .9.12.1 peers.  By coincidence I have to move my server & its virtual machines to a different building this week. I was waiting until after the hard fork, but since we are waiting for a fix I figured I would do it today.  It should be back up Saturday.

Edited: For clarity

terracoin-cli getauxblock
error code: -1
error message:
CreateNewBlock: TestBlockValidity failed: late-legacy-block (code 16)

[hanzac]

Can ahmedbodi explain why this code is written like this?

https://github.com/clockuniverse/terracoin/blob/master/src/primitives/pureheader.h

Code:

    inline bool IsLegacy() const
    {
	return nVersion <= 536870912;
}

536870912 is 2²⁹, this is very strange, it seems no where to set big value like this.


While the dogecoin is written like this.
https://github.com/dogecoin/dogecoin/blob/master/src/primitives/pureheader.h

Code:

    inline bool IsLegacy() const
    {
        return nVersion == 1
            || (nVersion == 2 && GetChainId() == 0);
    }

[hanzac]

It seems our hero developer is busy on some green coin wallet.

Hi Peers,

I think you can modify the source code a little and then it will work.

     }
 };

Since it's 1 days more that no new blocks, we need to set maxtipage. e.g.:
terracoind -maxtipage=1382400

[mrbodz]

afraid that wont work. Since terracoin launch. Some mining pool has been creating blocks with an invalid block version. That is why i had to set the islegacy version to the highest value they made. Apparently this is now conflicting with merged mining.

EDIT: unless its working for you?

EDIT 2:
103c103
<         consensus.nLegacyBlocksBefore = 806000;
---
>         consensus.nLegacyBlocksBefore = -1;

Everyone could try running this patch against their coind's and see if it accepts the block. If so i will apply it to the github and we can move the hard fork forward

You need to restart and use maxtipage longer than 2days, e. g.
terracoind -maxtipage=1382400

Right, I just did that and now it works.

Cheers!
