November 2021 update: grin payments are currently not being accepted. My payments code broke, and since grin payments were never very common, it hasn't been a priority to fix it.

I'm super excited about grin. All past altcoins have been just Bitcoin with a few bits tacked on; occasionally these extra bits are useful/interesting (eg. Monero or Ethereum), but in the vast majority of cases this extra stuff is just meaningless marketing-oriented garbage. But grin is packed full of useful innovation from top to bottom; moreover, it's clearly built in the same cypherpunk spirit that Bitcoin was: increased freedom/sovereignty through technology.

Therefore, I'm happy to announce that the forum is now accepting grin payments automatically, probably the first site other than exchanges to do so. You'll find a link at the bottom of the evil-fee and copper-membership pages.

grin is new and clunky to use. I don't expect many people to use it, honestly. But I needed to rewrite the forum payments system anyway in order to support LN in the future and to fix some longstanding issues with the old code, so adding grin support worked out nicely.

I don't recommend buying or not buying grin. Due to its emission schedule, I'd guess that its price will have a general downward trend for quite some time, but who knows. Currently I own zero grin (though I will be buying from the forum all grin obtained), I was not paid to add grin support, and in fact not a soul knew that I was going to do so. grin support might be removed later if it dies off or becomes too time-consuming for me to maintain.

I tested this with grin's floonet (testnet), but not mainnet yet since I don't have any grin. Hopefully it works. Smiley



A few observations I had while implementing this:

By default they want you to essentially pay to IP addresses. This was stupid when Satoshi tried it 10 years ago, and it's stupid now. At the very least you should strongly encourage (ie. nearly force) people to give out public keys along with their IPs, since otherwise MITM attacks are trivial. Even then it sucks to require the recipient to run an open-to-the-Internet server at all. And for goodness' sake, don't use the broken/centralized HTTPS system; the Bitcoin Core devs have been going to a lot of trouble trying to remove that garbage from Core.

A better protocol for the copy/paste method is needed. For one, you shouldn't have to use intermediary files. I was annoyed when I did grin wallet send -m file -d - and it actually created a file called "-" instead of writing to stdout like it should.

grin needs to be much better at handling transactions that never continue beyond the first or second step in the three-way transaction process. They probably shouldn't even show up in the main transaction log.

Currently I think that there's no way for the recipient to get the modified slate after running receive the first time (eg. if it gets lost), which is nuts. And currently there appears to be no reasonable method for proving that you sent a transaction.

Very interesting to see the forum implement an outside project in this fashion.  Grin is indeed an innovative project and I am mining it to get my hands on some.

Wow, never expected something like this to happens. I personally started to look and learn about Grin after I know theymos posted on their thread. And now this? theymos your shilling is awesome Cheesy

Kinda dissapointed that Howeycoins can't achieve the same thing despite being older.

@theymos - Your grin link seems to be broken at the moment.  Should be: https://grin-tech.org/

I think that grin-tech.org is just down right now. Nevermind, fixed. Thanks.

Kinda dissapointed that Howeycoins can't achieve the same thing despite being older.

Since everyone who invested in howeycoins became a billionaire, I was worried about what would happen to the world economy if I promoted it even more.

Nooo! This is only going to drive prices up when it comes to trading Grin! Interesting to see you implement it so early on despite still having concerns for the future of Grin.

So let me get this right...

Mimblewimble (which is really cool, don't get me wrong) all the sudden gets theymos's support on day 1, when grin's only interesting factor is mimblewimble.  Whereas Monero has Ring Signatures, Ring Confidential Transactions, Stealth Addresses, LMDB, bulletproofs, subaddresses, ASIC resistant cryptonite algo, and possibly Kovri soon™ and it's only a side "interesting" project?

Wut?
¯\_(ツ)_/¯

Monero

Mimblewimble has privacy features, but it also has the first really impressive, true scaling solution in crypto. Privacy-wise, Monero is probably better overall, but its scaling is abysmal, and neither coin can be treated as an impenetrable black box.

There's still 14 days and 22 hours before the HoweyCoins ICO begins, so technically its not older.

Grin seems to be only ready for Linux and OS thus far. Otherwise I would check it out.

I'll wait until they make it a bit more user friendly for morons like myself.

You can mine grin on windows, been testing it from pre-genesis block.

Check out some of your pool of choice's links for the windows miner version.

Just likewise what theymos said in his original post,if it proves to be unsustainable and cannot be maintained it'll be removed in the "future"
For now it is implemented and it's progress would simply be watched closely and subject to changes definitely.

This. Monero will end up a dead coin sooner because of all the bloat it implemented.

Any chance you'll accept another cryptocurrency (XMR, ETH or perhaps DOGE) soon?
To be honest I am not fan of accept any altcoin. Since it's BTCitcointalk, and I believe that forum related all payment should be by BTCitcoin. Although here is so many altcoin board, but forum was build based on BTCitcoin. I am not agree with accept any altcoin for forum payment. Never mind if admin support any coin personally but official payment mathode should by BTCitcoin only.
