[ANN] Mergecoin: bitcoin with merged mining patches applied

[khabaro]

how is 90% solution not improvement?  just saying its been two years since some merge mine coins updated.  target is always moving anyway.  sometimes its best to make some progress than none.  its can still be sustainable and well developed if no major bugs introduced.  that has nothing to do with which version is targeted.  if new database is biggest hold up why not upgrade to just before new database.

The recent I0Coin update to recent Bitcoin code seems to work, so maybe now people can update their merged mined coins based on that instead of needing this "mergecoin" thing for now.

Link/s to git/s? I can try them all: ixc, i0c, nmc, dvc

[ahmed_bodi]

link to the git and will it allow merged mining as a secondary chain?

[markm]

Yes, it seems to be working as a secondary chain.

Apparently it was made by progressively applying bitcoin updates to the old i0coin code all the way from the old bitcoin it was based on up to latest or very recent bitcoin (one that uses the new database instead of BDB for the blockchain).

So basically it is mergedcoin plus the individuation of chains stuff that makes i0coin different from just bitcoin with secondary chain merged mining patches applied.

It should be as easy to adapt all the others from as mergedcoin itself, maybe even easier since for a lot of the places where name of coin appears you can search for i0coin instead of for bitcoin, which is nicer since bitcoin appears in variable names and file names even in all the individual coins are that are not bitcoin.

So really even if we had made mergecoin, it would be easier in some ways to base off of whichever coin first made its own new self from it than from mergecoin itself, unless the first to do so was one with more than just the usual clonecoin copy and paste changes we see so much of nowadays.

(e.g. if devcoin went first, ouch, basing off that would not be so simple as just using mergecoin directly as it changes way more things than the typical clonecoin does.)

I can't remember where I got this new i0coin, git does not conveniently tell me where it pulls from when i do git pull nor even when I do git status, I don't know enough git to have it simply tell me where the repo is.

Presumably it was posted in i0coin's own thread though or maybe some "I made a new i0coin version" thread or something as i did come across it somehow.

Sounds like its possible that in the near future a working solution appears?

[ahmed_bodi]

i see, well then im going to find and clone it and attempt to build a copy for bytecoin, ill post the results here soon

git remote show origin

So you have created NEW i0coin, NOT make old one working as 0.8.x ?

It wasn't me. But supposedly they started with the i0coin everyone was using and patched it using the bitcoin historic record at github to bring it in steps more and more up to date.

I guess doing the updates in stages made each individual pull easier to resolve/apply.

Ok, I have compiled and run -rescan, it accepts my chain up to

Code:

SetBestChain: new best=70c6c7dd6b4735285c22836524774cd8ea41a5438809df9a5da8a7154fbbbb55  height=526859  log2_work=62.417927  tx=612806  date=2012-12-01 09:05:43 progress=0.010692
ProcessBlock: ACCEPTED
Loaded 526860 blocks from external file in 850969ms

But now I have no nodes to connect :/

Also, memory issue is NOT resolved, it eats 1GB already (vs ~200MB for bitcoind)

Shutting down...

[markm]

No, the master branch does not resolve the memory issue, as the issue is not a leak but rather is something all coins will one day face, the sheer amount of outputs, bitcoin keeps them all in RAM.

There is a version with a fix for that, but it has not been made the master branch yet.

Back when I grabbed this and used it, the only fix for the memory was a dirty trick kludge i did not want to use, so that master you just tried is what i am running. i was already throwing RAM at the coin so have no problem that it still legitimately needs lots of RAM.

There is though now a proper fix, that stores the outputs in the database instead of in RAM, it is one of the branches, see the I0Coin resurrected thread.

I am not using it yet myself but the coder seems confident it will work okay.

If so maybe all coins will eventually use it as they too run up against RAM consumption problems.

EDIT oh its the block headers not the outputs that eats the RAM, merged coins have all the merkles of all the coins they are merged with in their headers.

guys, is it worth to invest? it pumped a lot at btc38

[Bisonindatent]

this is definitely a scam.
no team +bought twitter followers etc.

No.

this is definitely a scam.

That twitter account is not related to this project.
