The JoinMarket IRC channel so far was hosted on freenode, which is very unfriendly to tor users.

So I've set up an IRC relaying bot between the freenode channel and a channel on cyberguerrilla which is far more friendly to tor.

Tor Details:

Code:

channel = #joinmarket
host = 6dvj6v5imhny3anf.onion
port = 6697
ssl enabled

Just for clarification: this is referring to the IRC channel we use to *chat*, not the IRC channel(s) we use for joinmarket orders/joining activity (what we call the "pit" like trading pit).

In the spirit of "Coinjoin that people will actually use", I'm wondering if any of the regular bitcoin wallets have integrated joinmarket, or have announced any plans to do so?

Along these lines...

Is there a joinmarket API that would make it straightforward for a wallet to integrate?

Has any effort been made to approach wallet makers?

If not, perhaps we should open issues requesting joinmarket support on their respective github pages.

IMO joinmarket is at too early of a stage for this, there are still a few problems that would be nice to fix before anything happens.
Right now it seems most of the adoption comes from people using the tumbler script.

Looks like alot of the bumps are getting smoothed out along with more volume. Steep learning curve but im catching on.

Hi, I found the output of wallet-tool.py hard to read so I made a patch that formats the output into text tables with borders.

Here's a very basic example:

Code:

+-----------+---------------+
| Mix Depth | Balance       |
+-----------+---------------+
|         0 | 0.34898343btc |
|         1 | 0.23468934btc |
|         2 | 0.23123434btc |
|         3 | 0.82397493btc |
|         4 | 0.22356223btc |
+-----------+---------------+
| total:    | 1.84839232btc |
+-----------+---------------+

Wallet addrs and history are also in tables.

JoinMarket v0.1.4 has a new feature that calculates your effective interest rate from running a yield generator, as though it was a bank account.

https://github.com/JoinMarket-Org/joinmarket/blob/master/doc/release-notes-0.1.4.md#wallet-history

To use, configure JoinMarket to use a Bitcoin node as a method of accessing the blockchain and run:

Code:

python wallet-tool.py wallet.json history

It takes into account all your deposits and withdrawals, so it should calculate the rate even if you were adding to your wallet or spending from it.

For my own yield generator wallet the figure is 0.67% per annum. I've been running it since the very start including when very few people used JoinMarket, so you can expect my yield to be on the low end.

grubles tried this and got 3.2% as an effective interest rate. I assume he's been running it for less time.

Whats your yield ?

https://www.reddit.com/r/joinmarket/comments/4hwwa0/calculate_your_yield_generators_perannum_return/

I'm aiming to get more people running yield generators.

Riding the pump-and-dump rollercoaster of Eth/TheDAO and similar is ultra high risk/reward, JoinMarket is more aiming for the slow and steady winning the race.

Earning about 1% per annum in a deflationary currency with basically zero risk where you can withdraw your money at any time must be unique in the cryptocurrency space.

I had the same issue some time ago - the short answer is that the JoinMarket protocol requires you to have the target address of a join in your wallet. I. e., patientsendpayment only works if you send to yourself, and then only if you import the target address into your JoinMarket wallet. I think there is some incentive to change the protocol to make it work as originally envisioned, but I don't think that actual work is already done on that.

Thanks, that's good to know.

I've also talked to belcher about this error from bitcoind's debug.log:

Quote

2016-04-17 11:41:45 AddToWallet update
2016-04-17 11:41:45 runCommand error: system(curl -sI --connect-timeout 1 http://localhost:62602/walletnotify?) returned 1792

This occurs when a new transaction is detected, which was sent externally (e.g. not part of a joinmarket-transaction) to the joinmarket-wallet. This error can safely be ignored. If a yield-generator is running, he won't see the funds though until restarted.

My patientsendpayments seems to crash every time someone actually tries to initiate a transaction.
First I assumed there might have been some communication problem, but now this has happend two times in a row making that reason unlikely.

In my case, this was not much of an issue, since I wanted to use that for internal wallet restructuring and sent to myself. Importing the target address' private key into JoinMarket made it work. Not sure if that is an option for you, though.

Running Debian Jessy, Joinmarket with bitcoind, both over TOR. Start command:
python patientsendpayment.py -f 5000 -w 48 -c 5000 wallet.json 1000000

There's >0.1btc in mixing level 0 of the wallet, the payment to be sent was 0.01 btc.

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

I wonder how you can track bitcoin and S&P at the same time though. For me, selling bitcoins to put them into whatever other economic opportunity feels stupid for me, as I'm so bullish on Bitcoin. Earning 3% on bitcoin savings though sounds great.

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 Wink

, then JoinMarket is not for you.

as far as i understood one of your biggest aims in order to help people is to make their transaction fees a bit lower

Joinmarket is not at all about reducing transaction fees.

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

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
