Is there a block explorer for devcoin?

I0coin is what I'm actively working on. Ixcoin I provided patches for the timetravel fix and the merged-mining implementation for the coin maintainer (switching on at 40,000 and 45,000 respectively). So far he's done nothing with them so I guess those won't be the actual switchover block times.

Is there a git repository, based on the original bitcoin repository it was forked from? If not, do you know the commit id where it was forked? If not git do you have any version control repository?

ArtForZ didn't do Namecoin. 'vinced' did. I ported namecoin's merged mining support to i0coin and ixcoin recently. I could do the same for devcoin assuming it's similar. Is devcoin based on the standard bitcoin git repository?

You need to be aware that it's a blockchain forking change though. It'd have to have a block number that it turns on and all clients would need to update. Those that don't will be on an incompatible fork of the chain.

Confirmed, nice:

If you use the command line client you can prove it by signing a message using that address:


Show the result of that here. People can verify with:

Thanks all for the donations, much appreciated!

Yep,thanks!

Or a native C miner and call it using the Android NDK.

Version v32507 of i0coin is available. Source and windows binaries are included. Only minor changes but I wanted to get a recent checkpoint out:

• Added new hardcoded seed node
• Add a checkpoint at block 142,900

I've uploaded the source to github for v32507 of i0coin. This adds a new hardcoded seed node and a checkpoint at block 142,900. I'll add windows binaries soon: https://github.com/doublec/i0coin

Edit: Window's binaries are up: http://i0coin.bitparking.com

Assuming you want to mine namecoins as well as i0coins. Get and run the latest namecoin daemon, 0.3.24.64. Get and run the latest i0coin daemon. Get the i0coin source. Inside the 'contrib' directory of the source there is a 'merged-mining 'merged-mining-proxy' python script. Run this with command line arguments like:


Replace 7332 and 8332 with the ports you are running the i0coin and namecoin JSON-RPC server on respectively (the above are the defaults). Replace 'user' and 'password' with the rpcuser and rpcpassword's used for the respective programs. Point your miner to http://127.0.0.1:10332 as the address to mine and use any username and password, they are ignored. Mining should then start.

Block 40,000 is when the timetravel fix activates, 45,000 is when merged mining activates. Assuming the ixcoin developer keeps the same block numbers as I used in the patches. Probably best to make them larger now since there won't be time for people to get new clients.

It's nothing to do with me - I just provided fixes for issues raised by the ixcoin developer to claim a bounty. Block 40,000 is getting close - if you're not going to release a client with the timetravel exploit fixed soon you'll need to change the block switch on time. Any timeline?

Not yet, you have to wait for block 160,000 before that becomes possible. Currently only i0coin+namecoin (or other chain that has support as a auxiliary merged mining chain).

I hope those of you mining i0coin at the moment are merge mining namecoin at the same time and making extra out of it. Namecoin difficulty is fairly high though so it's probably not a big deal.

Merge mining pull request enabling support as an auxiliary chain at block 45,000: https://github.com/ixcoin/ixcoin/pull/5

I tested mining bitcoin, namecoin, ixcoin and i0coin all at once, successfully getting blocks. This was on my own internal forks of the block chains so I could mine at low difficulty. I'd suggest doing your own tests too to be comfortable.

While testing I noticed the genesis block for the ixcoin testnet is invalid. it'd be great if you could generate a valid testnet genesis since it makes testing a bit easier.

Merged mining:

https://github.com/doublec/ixcoin/tree/mergedmining

This enables ixcoin as a primary chain on the main network. It is supported as an auxiliary chain on the testnet only. I'll do some testing then push another commit to enable it as an auxiliary on the main net at a certain block number. Then I'll do a pull request.

Primary chain support is still useful though. It means you can mine ixcoin and namecoins together right now by building this branch as it's a non-forking change.

Adds a checkpoint at block 36,500:
