Monappy Reopening Announcement (Translation)

The following is a translation of IndieSquare's announcement post.

To begin with, we'd like to extend our apologies to the users of this service and related persons affected by this incident. We're profoundly sorry that it took so long for us to resolve this incident and get to the point of resuming service and for keeping you in the dark.

To briefly recap: on 1 September 2018, an unauthorized party was able to access the hot wallet in use by Monappy and drained the wallet's Monacoin balance. In response, to prevent further damage to customer assets and to perform a root cause analysis, the service was taken offline. Since then, we've completed improvements to secure the system as well as improvements to the administrative side of the service, and are pleased to announce that we are making final preparations to reopen the service on 7 October, 2019.

Going forward, we will be periodically auditing the service and making security improvements wherever possible, and hope to regain your trust in the process.

As the service reopens, affected users will be fully reimbursed for damages. Details are below:

Reimbursement amount: 93078.7316 mona
Reimbursed persons: 7735 people
Reimbursement procedure: Once the service reopens, affected persons may login to their account and be able to withdraw their Monacoin balance as normal.

Service Reopening Details

In order to provide the safest environment for the affected Monappy users to withdraw their funds, only a subset of users will be able to access Monappy at first. We will be incrementing this number regularly, so we hope for your cooperation during this process.

On 7 October, 2019 at 10AM JST, an email from an email address will be sent to all existing Monappy users regarding the reopening.

  • On login to Monappy, you will be strongly urged to withdraw your funds to a safer wallet (tl note: an offline wallet on your PC, for example), leaving only the bare minimum you need in your account (tl note: should you want to keep using the service).
  • Please note, if you make a mistake with the recipient address during the withdrawal process, due to the nature of blockchain we will be unable to assist you in this matter. Please double check your address before clicking withdraw.
  • Should there be a rapid increase of traffic or some other unforeseen problem, we may temporarily suspend the service without notice.
  • You may not be able to login to your account if accessing from a different IP from before. If this turns out to be the case, please email
  • For those accounts with significantly large balances, identity verification may be required.
  • We expect all users to be able to start using Monappy in approximately 1-2 weeks.


  • We will never ask you for your email address or password on the basis of this incident via any communication method, including email, phone and postal mail.
  • We will never send you any email including an attachment regarding this incident. Please do not open any if you do receive something like this.
  • We will never ask you to input your Monappy account's email address or password on a domain other than Please take due caution if you receive a suspicious email requesting you to do so.
  • Should we discover an issue not currently known, we may postpone reopening of the service to a later date without prior notice.

Events Leading Up to Reopening

In an effort to restore service, IndieSquare has hired a new member who has experience with cybersecurity and supporting financial systems to the team. During this process we revised the application's architecture in an endeavor to improve security, which includes changes to the monitoring system as well. We intend to introduce changes as needed along the way in an attempt to keep the service secure.

(tl note: I'm leaving this part untranslated as it's just review of what architectural changes they made, much of which should be matter-of-fact knowledge to system administrators. main thing for non-nerds is that there's more anomaly detection. also, I'm tired.)

Future Changes

In accordance with amendments to the Payment Services Act to go into effect in April 2020, we intend to remove the service's dependency on a hot wallet. We're also looking to developing integrations between Monappy and dApps, so that users can eventually have full control over their private keys.

No, she doesn't speak English, and yes, there are (probably) other English speakers in the chat, but they're not there to chat with you. Stop asking.


新年からもう5月経ったか、、、今年はもう目茶苦茶でしたね。平成が今夜終わるらしい から平成最後の報連相行ってみたいです!ギリギリで!

Dang, it's already 5 months into the new year. It's been a rollercoaster of a year so far. Anyway, it looks like Heisei is ending tonight so I figure I'd do a quick update!

やっとホームページのデザイン更新しました!まだ完成ではないが、スマホにも使うこと になりました。このテーマのベースを分かる人いますかね?

I got around to writing a new theme for my blog finally! It's only partially complete (will be working on it for a while) but unlike the one that's been in use here since 2014, this one should render fine on mobile. Wonder if anyone knows what the theme is based on?

今年日本に引っ越さないことになりました。4月18日に入管からの非交付の報告が 来ていて、前の会社から退職したごろの企画まだ再開します。短大に行って、そして カリフォルニア大学バークレー校に転校(まあ予定より一年遅れてる)。だが、他の道も 調べていますから、また何か変わるかもしれません。

Japan isn't happening this year. Japan's Immigration Bureau sent me a rejection letter on the 18th of April on the basis - stating pretty much what I expected - of my lack of a degree and experience. So, I'm falling back to my original plan from when I quit my job last year, of going to community college in preparation for a UC Berkeley transfer, albeit set back a year now. I'm still considering some other options, though.

以上です。今週また書こうかな。 そろそろゆにチルとしてUNiONWAVE-clear0 カウントダウンライブに配信で参加します! 平成ありがとう。令和よろしくおねがいします!

That's it for now. Maybe I'll write another post this week. Time to go watch YuNi and friends at UNiON WAVE-clear0.

The Quest for a Suitcase-Compatible Workstation

my requirements:

  • fits in my carry-on luggage. approximately 250mm x 330mm x 500mm
  • mobo should support 4 DIMM slots, a GPU, and at least 1 m.2 nvme
  • GPU must not require a PCI-e riser cable (point of failure)
  • mobo must have IPMI
  • case preferably has room for 2 3.5" HDDs. 2.5" SSD is a bonus, but I have nvme already
  • case should have appropriate dust filters and be capable of decent air cooling.
    • water cooling raises complications for getting through TSA.

case considerations: there are no itx motherboards that tick all my boxes, specifically 4 DIMMs. thus, the case needs to support micro-atx or larger.

Jonsbo C2 - poor cooling capability (esp if you opt to mount drive instead of fan), not long enough for a GPU, only 1 drive bay with matx

Jonsbo/Cooltek C3. It's made of aluminum (= good heat dissipation), only 20 litre in volume, only 2kg (about 4 pounds) in weight. It's a very good mATX case that is lighter and smaller than many ITX cases. It can even fit into a backpack. Supports fully ATX power fupply and graphic card up to 27 centimeter in length.

Jonsbo V4 - unobtainium, seemed pretty cramped but usable. possibly runs hot

Thermaltake Urban SD1 - UNOBTAINIUM BUT OTHERWISE PERFECT (it ticks all of my boxes). Server-like build in that you can pull out the motherboard tray.

Silverstone Fortress FT03 - the side panels have poor locking and easily come off, otherwise really interesting design and would have gotten this. but the diagonally oriented fan is apparently very noisy because the mount is only fastened on one end. hot-swap drive is dumb, would probably have been better with 2 extra 2.5" mounts. slim slot loading BD drive is expensive.

Thermaltake Core G3 - originally bought this for my "new" build after using my last for 6 years. It's like 2cm too deep to fit in my suitcase, and it requires using a PCI-e riser cable that I've grown to not like (given the Thermaltake-provided one was DOA). Good case overall though, if you're looking for ATX and slim.

Jonsbo UMX3 - might have been a good choice with decent cooling (unlike other Jonsbo cases), but depth was 28mm too long, and only 1 3.5" bay (but up to 4 2.5" if you went ssd only)

Raijintek Styx - hotbox. also literally 5mm too long in height. full length GPU doesn't fit when using an ATX PSU (need an SFX-ATX bracket) and thermals aren't super great, but would probably be just fine with a power conscious workstation (low power Xeon or Ryzen). super easy to build however - recommended to watch for caveats.

Fractal Design Node 605 - discontinued, would probably be spectacular but is 19mm too deep.

Silverstone Grandia GD05 - pretty strong option since it ticks all my boxes. CPU cooler options are limited to 70mm if using ODD (and you can use a full 5.25" ODD), 120mm if not, which is still not that great. dust filters are on the inside rather than the outside, so fans will accumulate dust. Easy to build.

Silverstone SG11/SG12 - Despite having a lot of openings, there are no dust filters. Otherwise, while noticeably bigger than other options, is an appealing chassis that would still fit in my suitcase. Probably the best option if you have a lot of SSDs (9)/HDDs (3).

Thermaltake Core P3 - why is this micro-atx open air chassis so big?

Thermaltake Core P1 - this is a mini-ITX chassis, but I have seen at least 3 reports of people using this with a micro-ATX board. Only fits 1 3.5" drive though. Would fit diagonally in suitcase as parts due to open air design (i.e. you would have to disassemble when moving), but cooling is, as you'd expect, pretty optimal. But it's super fucking heavy, I'm not sure you'd want to take it in a carry-on.

Jonsbo RM3 - Possibly a good option? Case exterior is nice. 6mm too long though. Airflow is limited to bottom intake.

Jonsbo U4 - 10mm too long, but a possibly good option that also fits full ATX. Airflow seems pretty optimal compared to other Jonsbo.

Corsair Carbide 260 - 10mm too wide. Didn't look into it further since I'm not a fan of the exterior.

Fractal Design Define Mini C - 59mm too long (or tall I guess, depending on orientation). Didn't look into it further. It's unfortunate none of the Fractal Design cases pass the geometry requirement, their cases have a really good rep (and cable management is amazing in this case).

Silverstone Temjin TG08E - 44mm too tall. This case seems to have a pretty good internal layout, airflow is great (it's the most touted at the SilentPC community, I believe), and ticks every other box of mine. But I guess that's to be expected with an extra available volume.

Silverstone Sugo SG09/SG10 - SG10 is the better looking version of the SG09. Ticks all of my boxes. Need to be careful with PSU selection, Silverstone's PSUs and EVGA's PSUs appear to be the only ones that are safe to use without making it difficult to fit alongside the 140mm intake fan and without risking the PSU extension cable from turning off the PSU because it's being routed over the switch. Changing the top 180mm fan to exhaust should make this case very optimal for cooling internal components except for the HDDs.
