Bitcoin. AI. Stablecoins. Tokenised markets. And probably a few terrible predictions about what happens next. 🧡

Sounds like a Tuesday.

Tomorrow, 6 October, Letz OffChain is back at Brasserie Millewee from 19:00.

And there is definitely no shortage of things to talk about.

Bitcoin has been climbing again.
Traditional finance keeps moving onchain.
Stablecoins are becoming actual payment infrastructure.
AI agents are starting to transact.

And somewhere in between all of that, we're still trying to figure out what the financial system of the next decade is actually going to look like.

Bull market back? Maybe.
AI changing everything? Probably.
Will everyone around the table agree on any of it? Absolutely not!

And that's kind of the point.

Letz OffChain isn't a conference.
There are no slides, no speakers and no requirement to know what a blockchain actually does before sitting down.

It's simply a table where people from completely different backgrounds meet, eat, drink, challenge ideas and try to understand what the hell is happening around us.

And because we're at Millewee, Innopay will of course be running too.

The full setup is there: browse the menu, order and pay directly through Innopay.
If you've never tried it, tomorrow is a pretty good excuse.

We spend enough time talking about bringing blockchain into everyday life.
Sometimes it's nice to just order dinner with it.

📍 Brasserie Millewee
📅 Tuesday, 6 October
🕖 From 19:00

Crypto veteran, AI nerd, entrepreneur, finance person, complete newcomer or simply curious about where all of this is going: grab a chair.

Come for a drink. Stay for dinner. Leave with at least one new idea, and probably three new arguments.

See you tomorrow, fam. 🧡

Iran uses Tether to evade sanctions.

The obvious conclusion?
Crypto needs to behave more like banks.

Except there's a problem.
The banks aren't exactly stopping it either. 🧡

A new investigation from Democratic staff of the U.S. Senate Permanent Subcommittee on Investigations examined 846 crypto wallets sanctioned or targeted because of links to Iran and its regional proxies.

According to the report, 84% transacted exclusively or predominantly in USDT. Investigators argue that Tether has become an important component of Iran's shadow banking infrastructure, including networks connected to sanctioned entities and regional proxies.

That's serious.
And it shouldn't be dismissed with the usual: "But criminals use banks too."

They do.
But that doesn't make illicit stablecoin activity irrelevant.

It does, however, raise a much more uncomfortable question.

Only days before this report, an investigation found that a Kremlin-backed network managed to move $6.9 billion through the international banking system, using front companies, forged documents and accounts touching major global banks.

Banks operating under decades of AML rules, KYC requirements, sanctions screening and enormous compliance departments.

So perhaps we're asking the wrong question.
Instead of: “How do we make crypto comply like banks?”
Maybe we should also ask: “How effective is the compliance model we're trying to copy?”

Because AML isn't free.

Banks spend enormous resources identifying customers, monitoring transactions, screening sanctions and producing compliance documentation.

Those controls can stop illicit activity.
They can also make illicit finance more difficult and expensive.
But clearly, they don't eliminate it.

And compliance has another consequence we don't discuss enough: the higher the fixed cost of participating in financial markets, the easier it becomes for large incumbents to absorb it and the harder it becomes for smaller competitors to enter.

Regulation designed to keep bad actors out can therefore also become a moat around the institutions already inside.

That doesn't mean abolishing AML.
And it certainly doesn't mean ignoring Iran's use of USDT.
It means we should stop pretending the choice is between: "regulated banks = clean" and "crypto = illicit".

The evidence is considerably messier.

Bad actors don't have ideological loyalty to blockchains or banks.
They use whatever financial infrastructure works.

The interesting question for the next generation of financial regulation isn't whether we should fight illicit finance. Obviously we should. It's whether we can design systems that fight it more effectively, more proportionately and at a lower cost than the system we inherited.

Because if we're rebuilding financial infrastructure anyway... perhaps we shouldn't automatically rebuild every inefficiency with it. 🧡

Summer is technically over. The terrace apparently didn't get the memo. 🧡

Tomorrow, 29 September, we're back at Indie's for another Letz OffChain.
And with Luxembourg still giving us decent weather, we're planning to make the most of the terrace while we still can.

Is the crypto bull run waking up again?
What the hell is happening with AI?
What are markets doing?
And what will we all be arguing about six months from now?
Who knows. But that's exactly why we have a table.

Come have a drink, grab some food and spend the evening exchanging ideas with people from completely different backgrounds.

And because we're at Indie's, Innopay will of course be there too.
Already using it? You know the drill.
Never tried it? Come say hi and we'll get you started and you'll get 10% off when paying with Innopay!

- Indie's
- Tuesday, 29 September
- From 19:00

You don't need to be a crypto expert.
Just bring some curiosity and join the conversation.

See you tomorrow, fam. 🧡

Crypto-assets are born as data. Securities are born as law.

That distinction matters when we talk about tokenised securities.

A cryptocurrency or token is natively a digital object. A security, by contrast, is fundamentally a legal object: a share, bond or other set of enforceable rights.

Tokenisation tries to bring the advantages of blockchain, automation, near-instant transfer and settlement, broader access and potentially lower costs, into the world of securities.

But “tokenised security” can mean very different things:

1️⃣ A token representing a conventional security

The actual security remains recorded at a traditional Central Securities Depository (CSD). The blockchain token represents an entitlement to it.

The CSD remains the ultimate source of truth. This can bring benefits, but also creates a new reconciliation problem between the blockchain and the traditional securities register.

2️⃣ A digitally native security on a CSD-operated DLT

There is no conventional security underneath: the security itself is issued on the ledger.

But the infrastructure remains controlled by a CSD. The technology changes; the institutional architecture largely survives.

3️⃣ A genuinely DLT-native securities market

This is the more radical model: the ledger itself becomes the market infrastructure, potentially combining trading and settlement and allowing securities to move in near real time.

Remarkably, the EU's DLT Pilot Regime - Regulation (EU) 2022/858 - explicitly recognises this possibility.

And this is where technology meets market structure.

If DLT can combine functions today performed by trading venues, settlement systems and CSDs, incumbent infrastructures such as Euroclear and Clearstream are not neutral observers of that transformation. Their legitimate concerns about stability, investor protection and market integrity coexist with an obvious structural conflict of interest: some of the efficiencies DLT promises come precisely from eliminating or radically changing functions on which the existing post-trade architecture is built.

The DLT Pilot has so far produced very limited activity. ESMA acknowledged its limited uptake, and the European Commission has now proposed substantially expanding and relaxing the regime.

Perhaps the lesson is simple:

You cannot seriously test disruptive market infrastructure if the experiment is designed primarily around preserving the architecture it is supposed to challenge. 🧡

This evening, we're taking the orange table back to Brasserie Millewee. 🧡

Tuesday means Letz OffChain and this week we're heading back to one of the places where talking about crypto and actually using it can happen at the same table.

Good food, a few drinks, familiar faces, new ones, and conversations that have a tendency to start with blockchain and somehow end up absolutely anywhere.

And yes, Innopay will be there.
Already using it? Pay with it.
Never tried it? Even better.

Come over, grab your phone and we'll show you how it works. It takes a few minutes, and then you can actually use it to pay at Brasserie Millewee.

Because we can spend hours talking about adoption... or we can order dinner with it!

📍 Brasserie Millewee
📅 Tuesday, 22 September
🕖 From 19:00

No crypto knowledge required.
No membership required.
Just curiosity and an empty chair waiting for you.

See you later, fam. 🧡

The CLARITY Act just failed to bring clarity to crypto.

Yesterday, the U.S. Senate failed to advance one of the most important attempts yet to establish a comprehensive regulatory framework for digital assets.

The procedural vote ended 49–50, well short of the 60 votes required to move forward.

But perhaps the most interesting part is why.
Because this stopped being only a debate about crypto regulation.
It became several political battles happening at the same time.

One was about Trump.
Democratic senators argued that the bill's ethics provisions did not go far enough to address potential conflicts surrounding public officials' crypto interests, particularly President Trump's own involvement in the industry.

Another was about banks.
Banks have been pushing for tighter restrictions on stablecoin rewards, warning that attractive yields could pull deposits away from traditional banks and affect lending.

Crypto companies, unsurprisingly, see things differently.

Then add developer protections, consumer safeguards, market structure, SEC vs CFTC jurisdiction...
And suddenly a bill designed to answer: “How should America regulate crypto?”
was also trying to answer: “How should politicians participate in crypto?”
“How much should stablecoins be allowed to compete with banks?”
“Who gets to regulate what?”

That's the fascinating part.

Sometimes legislation doesn't fail because people disagree about the technology.
It fails because the technology starts touching too many existing interests at once.
Banks. Regulators. Politicians. Fintechs. Crypto companies. Consumers.

And perhaps that's also evidence of how far crypto has come.
Ten years ago, politicians could mostly ignore it.
Today, crypto policy intersects with banking competition, financial markets, political ethics and even the future architecture of money.

The CLARITY Act may not have advanced.
The questions it exposed aren't going anywhere.

Because crypto can be regulated. It can be restricted. It can be argued about for another decade.
But it can't really be uninvented. 🧡

Your Tuesday plans just got 10% cheaper. 🧡

Tomorrow, 15 September, Letz OffChain is back at Indie’s.
And by now, you probably know how this works.

No agenda.
No presentations.
No awkward networking badges.

Just a table full of people talking about blockchain, AI, business, finance, startups, life... and inevitably something completely unrelated 20 minutes later.

Drinks on the table, good food, better conversations, with the OffChain fam.

And, of course, Innopay will be there too.
Because Indie’s is one of our Innopay partners, everyone paying through Innopay gets 10% off their bill.

Blockchain adoption is cool.
Blockchain adoption that makes dinner 10% cheaper is cooler!

Already using Innopay? Easy.
Never tried it? Even better, come over and we'll show you how it works.

📍 Indie’s
📅 Tuesday, 15 September
🕖 From 19:00

Regular, newcomer, crypto veteran or someone who still has absolutely no idea what we do every Tuesday... there's a chair for you.

See you tomorrow, fam. 🧡

Almost 4,000 BTC were drained from Liquid.
And the craziest part? The vulnerability appears to have been introduced while fixing another vulnerability. 🧡

Here's what happened, without the cryptography PhD.

Liquid allows transaction amounts to remain private.
But if amounts are hidden, nodes still need to prove nobody is secretly creating money. That's what range proofs help prevent.

Think:

1 BTC in → 1 BTC out versus... 1 BTC in → +4,000 BTC and −3,999 BTC out.

Both mathematically balance.
But the second one effectively creates thousands of BTC from nothing.

Now comes the bug.
Checking these proofs is expensive, so Liquid caches successful checks.

Basically: "I've already checked this. It's valid."

Attackers reportedly managed to create two different transactions with the same cache key.
First, they submitted a legitimate proof.
Liquid checked it and cached: VALID.

Then they crafted an invalid transaction that produced the same cache key.
Instead of checking again, vulnerable nodes essentially said: "Already checked this one." They hadn't.
And suddenly, fake L-BTC could be created and exchanged for real BTC from Liquid's reserves.

Brutal.

But here's the important distinction: Bitcoin wasn't hacked. The infrastructure built around Bitcoin was.

And this comes shortly after the Coldcard vulnerability we discussed recently.
Different systems. Different bugs.
Same reminder: The base protocol can be incredibly robust while wallets, sidechains, bridges, keys and everything built around it remain attack surfaces.

And there's another lesson here.

Some will respond: “See? Stop experimenting.” We'd argue almost the opposite.

Bitcoin needs more brilliant developers building, competing, testing and trying to break assumptions.
Because the answer to bad engineering isn't less engineering. It's better engineering.

Security isn't the absence of innovation. It's what happens when innovation survives adversarial reality. 🧡

Tuesday again? You know what that means. 🧡

Tonight, the OffChain table is moving to Indie’s.

No presentations.
No dress code.
No need to prepare your opinion on whether Bitcoin is going to $1M.
Although someone will probably bring it up anyway.

Just the usual Letz OffChain formula with drinks, good food, blockchain, AI, business, finance, life and completely unrelated conversations. Familiar faces, new faces and everything in between.

And tonight, there's an extra reason to finally try Innopay if you haven't yet.
Pay with Innopay at Indie’s and get 10% off your bill!

Yes.
We spent all this time talking about bringing blockchain into everyday life...
Apparently everyday life includes making your dinner cheaper. 😎

Already using Innopay? You know the drill.

Never tried it? Come over and we'll show you, it takes less time than deciding what to order.

📍 Indie’s
🕖 Tonight 08/09 from 19:00

Come for one drink.
Stay for the family.
End up discussing the future of money with someone you met 20 minutes ago.

Basically, a normal Tuesday at Letz OffChain. 🧡

See you tonight!

About last night... 🧡

Summer break: officially over. Letz OffChain: officially back!

Yesterday we returned to Le Croque Bedaine for our first gathering after August.

Was it our biggest table ever? Nope.
Some of the fam is clearly still squeezing the last few days out of their holidays.

But the energy? Exactly where we left it.

Good food.
Great conversations.
Familiar faces around the table.
And the usual mix of blockchain, business, ideas, life and whatever else the conversation decided to become.

And, of course, Innopay was right where we left it too.

Working smoothly, making payments ridiculously simple, and reminding us why having something we've built actually being used around the same table where so many ideas started never gets old.

But most importantly... The season has officially started again!

Yesterday was the warm-up.
Over the next weeks, everyone will slowly make their way back from beaches, mountains and wherever else they've been hiding from us.

And we'll be ready for bigger tables, more new faces, more conversations, more ideas and plenty more Letz OffChain evenings.

Where are we going next? We'll tell you very soon.
Follow the page and stay tuned.

We're back, fam. 🧡
