A curiosity:

After beta period, Is the code/protocol for JoinMarket (I didn't review it) gonna be ready for scalability and adoption/mixing of ('most liquid') altcoins like Litecoin?

• There's no beta, JoinMarket works today.
• It should work on any blockchain that is supported by libsecp256k1 or pybitcointools, and has a bitcoin-core-like API
• I didn't review the code either, it's a horrible mess. Maybe you can clean it up while/insteadof porting it to your shitcoin of choice.

Fairly serious bug that can crash all bots. Alert issued. Please update to v0.1.2

raedah discovered a bug that causes all bots in the channel to crash. It's quite a serious DOS. Anybody can shut down the market at any time. No money is at risk but we all need to update.

Here is the technical discussion on github. https://github.com/JoinMarket-Org/joinmarket/issues/400

See the release notes here: https://github.com/JoinMarket-Org/joinmarket/blob/master/doc/release-notes.md

Let us know if there are any problems.

New GUI tool, walkthrough at: https://github.com/AdamISZ/JMBinary/#walkthrough

Do not make any coinjoin transactions if you're running sendpayment.py or tumbler.py. Your coins are at risk if you do. Please update to the newest release v0.1.3

Malte discovered a bug where a race condition can be used by market makers to take more bitcoins in fees than previously advertised. The maker does not know exactly how much to coins the taker has, so its unlikely that all coins would be lost, but it's still a very serious bug that requires takers to update.

See the release notes here: https://github.com/JoinMarket-Org/joinmarket/blob/master/doc/release-notes.md

Here is the fix commit, it makes the orderbook database only be queried once instead of twice: https://github.com/JoinMarket-Org/joinmarket/commit/508d65f9a9c3f7ad7c542e11d19148c91b89e943

Let us know if there are any problems.

Malte has shown ethical behavior in telling me about this bug in private and giving time for it to be fixed. Ethical behavour should be rewarded, so for that reason I post his donation address here 1Gs6tTFQgWLngps5kfPg6TKoPfGA4GXdXg.

JoinmarketQt updated to reflect the above: https://github.com/JoinMarket-Org/JMBinary/releases/tag/v3-0.1.3

How does this compare with darkwallet?

How does this compare with darkwallet?

It's not possible to "invest" in DarkWallet.

JoinMarket lets you invest your held coins in a wallet which performs coinjoins with those who are willing to compensate you for the risk of using a hot wallet.

looking fine and dandy...   will follow..   :}

What's the ROI generally on coins held in this wallet if you use the yield generator?

[Sukrim]

You have to decide on prices and compete with others on the market.

Generally for me it is too low, but higher usage (more people mixing coins) might drive it up enough to be worth considering putting BTC in a hot wallet.

How low is low?

There is this script I've been working on that works out your historical effective interest rate.
https://github.com/JoinMarket-Org/joinmarket/pull/484

Me and some people who've been running for a long time get a value of about 0.7% per annum, but people who started more recently (presumably when transaction volume rose) report values of 3% or so. Also that script has bugs I can't seem to figure out so the real values might be different.

But yes if you want a get-rich-quick scheme of 100% earned per week guaranteed , then JoinMarket is not for you.

[jod_doj]

thats a pretty great service i think but as far as i understood one of your biggest aims in order to help people is to make their transaction fees a bit lower, though i dont think there will be a need to do that if there will be a block size increase, in this way the fees would go down once again to normal rates

Joinmarket is not at all about reducing transaction fees.

Take your off-topic big-block propaganda elsewhere please.

3% per year? I could just invest in a S&P mutual fund tracker if I wanted to make that much.

Low risk <--> Low return

No exceptions here...
