This Friday 29th, from 1200 UTC to 2000 UTC, we will teach you how to run a Tor bridge and answer questions about our anti-censorship technology.

Bridges are useful for Tor users living in oppressive regimes, and for people who want an extra layer of security because they're worried somebody will recognize that they are contacting a public Tor relay IP address.

The event will happen via text (not video or audio) on IRC.

An independent security researcher discovered a vulnerability in the OLED of hardware wallets in April 2019. Trezor Model T has a TFT display and is immune. Updating to the latest firmware v1.8.2 for Trezor One mitigates the issue. Read our disclosure:

I've just realised how much of an incredible invariant there is in Bitcoin-I'm-here-to-fix-it condition. Just look at all the case studies:

R3-CEV because banks knew better.

Bcash because Bitmain knew better.

S2X because "important biznizmen" knew better.

ZuckBucks because big SV and payment companies know better.

Endless obscure and pointless shitcoins because top academic cryptographers know better.

Everyone knows better. Nobody just wants to take part.

Save the date! We plan to release Debian 10 Buster on 2019-07-06

We are proud to announce the public release and open sourcing of Samourai Dojo. You no longer need to make the trade off of providing Samourai with your public keys in order to access the most private Tx analysis busting tools. Have your cake and eat it.

Github Repo: 

Installation instructions:


Just did my first in-person trade where I signed a Bitcoin tx at home and sent it to my phone. I then connected to my full node over zerotier, my full node is connected to the network via Tor.

I was able to use @samourai_official to broadcast the transaction to my full node during the trade, worked flawlessly. Bonus that my full node watches my trezor accounts, and sends me an encrypted email on wallet activity, so I could see that it worked right away.

That was cool.

Thanks @stephanlivera for your interview with @samourai_official, a very informative discussion on the Samourai team's Dojo, Whirlpool and other cool projects.

Back working on Joinmarket for a while, in particular cleaning up wallet and blockchain interfaces:

Also noticing activity on Joinmarket's pretty robust at the moment, I'm doing about 20 cjs/ 24 hrs (would have to do some block scanning to get global data, but, vague guess, could be 50-100 per day).

I just tried using WebApps Sandboxed Browser from @fdroidorg with @pixelfed and find it quite convenient compared to having it open in one of a hundred tabs in #firefox

Bitcoin shower thought:

Burned coins as a quantum computer bounty
(after the active coins have switched to post-quantum schemes)

Part of my approach to security in Bitcoin is to hold X% as GBTC in my retirement account. Trusted 3rd Party, yes. But it helps me 'distribute' my coins and allows me to avoid capital gains while BTC is taxed as property.

Eventually, I'm looking at collateralized loans against my "physical" BTC as another method to divvy up keys/custody and avoid capital gains as well. (This should be in a multi-party, multi-sig set up ideally.)

Just got in a discussion on slack and realised that it'd really be worth itemising specifically that set of fungibility techniques in Bitcoin that could at least theoretically have as anonymity set the whole blockchain. This is what I came up with, any thoughts?

2. LN **
2. scriptless script swaps **
3. Coinjoin Unlimited (coinjoinxt + dual fund)
4. Pay-to-endpoint style coinjoin
5. Regular 'Coinswap' without scriptless script **

** all need either (1) or Schnorr for goal.

The following bitcoin addresses have been placed on a sanctions list by US authorities:

149w62rY42aZBox8fGcmqNsXUzSStKeq8C 1AjZPMsnmpdK2Rv9KQNfMurTXinscVro9V

I wonder what will come of this? What happens if those addresses start spamming random active addresses on the blockchain with small amount of BTC? This sanction will be very messy and difficult to enforce lol.

① Never ask someone if you may ask them a question.

Chances are they won't know if your question is acceptable until you ask it. It's a waste of your and their time. Just ask the question instead.
