TMGOX (The Magic Gathering Online Exchange)

DM’d you, shipping shouldn’t be that high.

Great designs! I was about to get a few stickers and a notebook but the shipping cost is really high (~$28). Like Askepios I’m a bit reluctant to pay that much if it doesn’t go to Grin devs.

It is a very silly error I just haven’t had time to fix yet will get to it in coming days.

Thanks @0xb100d! Please let us know when it’s fixed.

@Askepios @gosha it should be fixed now. The flat rate for large purchases was being set across the board (and was stacking with other shipping!), now it should be either $4 or $7. If you could test and confirm and let me know if that is still too high. Unfortunately some people are ordering from very far away and others from nearby and the issue arises from trying to make it fair for everyone.

Note anything extra will go toward grin development fund, TMGOX is not pocketing the shipping charges, every cent of profit goes to grin. Oh and also note all of our stickers are way behind schedule and are not going to go out until the second week of december at this rate, sorry about all of it.

Newest updates and transparency report:

Howdy y’all,

We are happy to publish our second transparency report, announce holiday sweaters (order now to get them by the solstice!), and the book preorder of the first version of GRINOIRE: a cypherpunk anthology! We have also fixed the flat rate shipping cost (we think) for stickers and other small accessories, please double check and let us know on twitter or via the gitter channel if you are still having any issues. Because some people are ordering very far away and some are close we had to pick a happy medium to cover our costs and not have to calculate on an order by order basis, there was some error where this was coming out WAY to high, and we appreciate people pointing this out. All extra shipping costs that go beyond our expenses will also go directly to the Grin Development Fund, so don’t think that you are wasting money on the clumsy shipping prices.

Also in sticker news, somehow all of our stickers arrived to Berlin for GrinCon0 well in advance of the shipment to our headquarters. If you ordered stickers we apologize profusely for the delay, please have confidence they exist and will get to you, and to make up for it we will be throwing in a handful of extras in your shipment. Right now our best estimate is that they will be going out the second week of December. That is more than a month delay for some of you, we are going to make it up to you!

First: check out our transparency report. We sold twenty-five things worth about two-thousand dollars! This is consistent with last month and we are eager to see the trend continue and hopefully grow. This resulted in a donation of .12777 BTC to the grin security audit campaign, or about ~$500 USD. So far everyone’s purchases have been making a significant impact and is a good sign that we will be able to maintain at least some level of consistent funding between campaigns. Once the mainnet launches and we see people mining grin and hopefully donating more to the development fund it will be interesting to see how the fund grows. In the mean time, please send us your ideas for new merch, and tell your friends. Recall many of these items are limited edition and won’t be available after the first planned grin hard fork. We are also looking at other suppliers to get our costs down so that we have more to donate to the development fund at the end of the day.

We were terribly honored to be given an entire slide in the very first talk at the very first GrinCon by the very first paid full time grin developer, yeastplume himself. We could not be more grateful to have a project as exciting and futuristic as grin to contribute our time toward, and are looking forward to many more years of support.

We are also looking forward to the first ever US GrinCon, we are working with the Blockcypher team to design sponsored merch and other deluxe limited edition merch for the event at the end of January. If you are going to be in the area for that, please also don’t miss the Stanford Blockchain Conference happening in the days directly afterward. Bulletproof wizard and true cryptomancer Benedikt Bunz is one of the contributors and should be seen/heard in his glory at any opportunity you can get. Good opportunity to ask him what he thinks about grin, and bug him to publish all of his papers ASAP! (Don’t do this.)

Holiday sweaters are going to be the absolute coolset thing you can wear around this month, so please order yours ASAP so that it can arrive in time for the solstice Dec 21. If you wear one of these to grincon or the Stanford conference you may very well get a free sticker.


Also very exciting, we are opening up the presale for the first edition of the GRINOIRE, an anthology of cypherpunk texts, key white papers, and other mumbojumbo, to help cover the costs of typsetting and printing, with all extra going to grin development fund, obviously. This very first edition is going to be funky, probably missing the sweet leather cover we were planning, and will leave all responsibility of navigating successfully up to the reader. But it’s going to be hundreds of pages long and the very first time many of the texts have ever been physically printed. Please click the link to the book, and then in the description follow the link to the git of texts already to be included and please submit a pull request with any other related works you think should be included. This is going to be an awesome group effort, and will eventually result in an extremely slick and serious looking edition we can all be proud of.

Note: this is at terrible mockup, but is probably something like what the first edition cover will look like.

We are consistently adding new merch and designs to the site, and the next couple will be a grin reaper tee as well as the yin yand one we teased last time. As always, please reach out on the forum or twitter or gitter if you have ideas.

Talk soon,



@0xb100d Shipping costs were still around $18 for ordering a few stickers. Sounds like it’s not fully fixed but also not a big issue as all profit goes to grin. I ordered anyway.

hmm okay i will makesure you get extras and will work to fix it for future orders

Need beta readers and or some extra sources?


Please for the love of god make it better written then the cyphernomicon or more grounded then assassination politics the political writting in this space is adismal

Don’t print the cyphernomicon raw, no one; i repeat no one wants to read that; it needs heavy abridging.

LOL I was planning on 100% including the unabridged cyphernomicon! I love the looping references and muddiness of it. Maybe you’re right though, abridging it could be useful without losing anything.

Absolutely looking for more recommendations of that era/genre/etc. And since you are such a tough critic I may call on you for editing feedback. Thank you.

Are the shirts supposed to be the same price as the sweatshirts. Most of the items are showing up as $42, I don’t know if that’s correct. @0xb100d

Hello, I have an idea for some swag. A little joke on the maxcap thing, how about a cap like the red one that says ‘maxcoin’, so that way captains of industry like myself can feel more secure knowing that there’s maxcoin cap in the grin space-time continuum somewhere lol. Thanks.

I got my Make Alice Great Again hat recently, it’s very high quality and probably the coolest hat in my collection. Great conversation piece.

Even if you never actually make them, and just have the page for it on the website, and just have it be forever coming soon. I dunno if that’s where you were going with that, but that would also be hilarious.

aaaand I just re erupted into laughter because of the font you used for ‘Max’, excellent choice for font, I feel like I need to buy one of those old asymmetrical skateboards…

Would it be possible if we could get the black color hats, with the original grin logo/colorway for the O? With the pepsi thing somehow to because I love it. Dunno, experiment. lol

Thanks! Oh and check out my new meme I posted in uncategorized “Soon…” I couldn’t resist. oooo spicy!

Yes I was thinking the Pepsi O was too much, I can try to put it on the back or side of the hat instead. Thank you you are full of good ideas. Will let you know.

Transparency Report #3: First of 2019 and Mainnet

Read it here too:


You helped us raise .41 BTC for the grin development fund.

Grin is alive and kicking, with some estimates putting the number of GPUs mining on the network at over half a million. All that proven work makes us tired just thinking about it, but the team at TMGOX has not been asleep, though we could use a good nap, and we hope you can forgive our delayed third transparency report to mark the beginning of our fifth month of sales and the first report post grin-mainnet-launch.

If you want the nitty gritty on the last two months, click the TLDR at the top. Long story short, sales are increasing and we sent nearly 200 different grin related accessories and fashion items out into the world since our last report. Tell your friends.

The low down:

  1. Please check your spam folder and see if you got a shipping confirmation, we have had to manually submit a handful orders our automation missed, but EVERYTHING has shipped!
  2. We have new outfit designs, new stickers, pins, a new book, and an update on the GRINOIRE book.
  3. Feedback requested on said book and a stamp project.
  4. We finally are shipping stickers… with bonus for your patience.
  5. We are working on accepting grin payments, very cool. Our monero discount has changed from 33% to 25% to make room.
  6. Future efficiencies game plan.

First: We are what amounts to a one man team, and wouldn’t have it any other way (nor is this a very complex organization), BUT we are working kinks out in our system every week and unfortunately sometimes our automatons let us down. We have sent out everything that’s ever been ordered, except for the GRINOIRE, as it doesn’t exist yet. Speaking of which…

Grinoire news: thank you to the dozen or so people who have pre-ordered, we couldn’t do it without you. The book is still in the development stages. There is going to be a heck of a lot in the first edition and it’s going to be a beautiful mess. Stuff like the wiki, top posts from the forum and mailing list, you get the picture. It’s overwhelming. It might look like an encyclopedia. It’s going to be great. We have an incredible new appreciation for Bryan Bishop. We still need your input on what else should be included in the first edition. Please comment on our repo and let us know your bright ideas; now is your chance to have your input memorialized in the first edition. Igno said we should include an excerpt from the Cryptonomicon and the choice was simple:

Harvard Li needs electronic cash. Not the lame stuff that people use to buy t-shirts on the Web without giving away their credit card numbers. He needs the full-on badass kind, based on hard crypto, rooted in an offshore data haven, and he needs it bad.

Ouch. Porqe no los dos?

We have a new book for sale. Technically it’s a zine, which is appropo we think. It is not strictly cryptocurrency related, but is called Hacking Finance Issue 01, and we couldn’t pass it up after seeing the slick design, and this article comparing Magic the Gathering to venture capital.

We also have a lot of other cool new stuff, some of the most creative conceived out of the blue by community members like yourself. See: a new sticker we have dubbed “Blockchains Not Bombs,” our first localized grin shirt for the grin Amsterdam meetup (there’s a sweater too), one inch grin pins (next up patches), a “Grin Reaper” tee we ripped off with absolutely no shame (from Banksy… who, in case you didn’t know, signed his name in the bitcoin genesis block right after the embedded newspaper headline), and a pretty slicke mimwim-yinyang shirt. Also, in case you missed it, grin now officially has a max coin cap. Economics of the entire network are irrevocably changed. The forks can stop now. (Note to self: start selling branded cutlery).

Another call for ideas: we want to make rubber stamps that you can use to permanently mark your local fiat cash with an advertisment for grin and a word against centralization. What should that stamp say? Coming up with a persuassive single sentence is key.

Blockchains Not Bombs

Grin Amsterdam Sweater

Grin Pins

Grin Reaper Shirt Back


Grin Max Coin Cap

We’ve been meaning to ask… is your t-shirt a lethal weapon? (coming soon tm).

Even more cool: we are preparing to accept grin as a form of payment on the shop. Truly we already do if you ask nicely, but @hashmap and Cycle42 are working on a simple payment service with easy integration we are waiting to show off. TMGOX should be one of the first storefronts where you can buy physical goods using grin, and hundreds of items at that. Exciting. To prepare we have dropped the Monero discount from 33% to 25% so that grin payments can take the top slot.

We have a feedback page for our crypto-payments servicer (speaking of which, maybe bug them to accept grin?), which is some sort of shallow reputation, but a reputation nonetheless. So far so good. A better form of repuation (and a treat) is seeing merch in the wild, which we have been retweeting as we come across it on the TMGOX twitter.

Regarding P2P exchange, we are still working on a forum for P2P atomic-swap trading, which should come in handy once the process has been ironed out. If you want to collaborate, we own the domain This is a hostage situation.

Some thoughts on the future. We are getting lots of stats on what sticks, what sells, and what stinks (see: our manifestote) and due to the nature of our bootstrapping, we can iterate like it’s nobody’s business on a whim. We already have some best sellers (the MAGA hat turned out to be an instant classic, for example) and plan to use this data to improve our margins and efficiency. In a year or so we should have grown enough and have enough data to start ordering wholesale direct and producing larger quantities of some of the things we know will sell. This is going to improve our margins and make more profit for grin development. We love this kind of tinkering. The most liberal of minds might even call it hacking. We will always have the #memblewimble style one-offs, but eventually we can pare down some of our selections and have some go-to items that keep the spice flowing like a well oiled worm.

Subscribe to the (fantastic) GrinNews newsletter for more general grin news, and follow us on twitter, and hop on our gitter to share ideas and feedback. Also, read this summary of why we need electronic cash from Coincenter (where our friend Neeraj works).

Truly grateful for the opportunity to do what we’re doing, with so much more to come. Congrats to all involved on grin’s “mythical fair launch.” Here’s to many years of experimentation and hoping all of the novel math Benedikt et al have been working on turns out to be viable and it can get implemented into grin. If you thought it was magical now just wait.
