Awesome.
I had some reluctance with Cashu before, based on some centralization and power the mint would have.
But using secure enclave is giving more trustless orientation.
So great work !

As a business trying to accept Bitcoin in the Nostr era
- You don’t just want to “accept Bitcoin”.
- You want to receive value natively.
You want Instant. Permissionless. No friction.
So you start looking for a way to plug it into your business.
And… nothing really feels right.
Too many layers, too much friction.
What you really want is simple.
Self-custodial, decentralized and loyalty oriented.
This is what I built: https://bitlasso.xyz

It’s funny how this things evolve.
Few years ago when people asked me about AI and blockchain I was really skeptical, as they were completely different world:
- one is completely decentralized
- the other one is based on centralized data
Today we are facing the emergence of those two worlds from the agentic revolution.
There are not anymore siloed.
Decentralization and AI is moving as speed of light.
Always recognize your wrong and moves ahead it is what makes human progress.
So now I think AI can be a strong case to make blockchain and decentralization a growth catalyst and bring more adoption.
But it goes beyond, Nostr is moving really fast to embrace that movement.
Future of decentralization and AI seems to promise great things !

Something big is happening on Nostr — and it’s not about social media anymore.
Programs and websites can now live directly on the protocol — signed, versioned, and published as events.
⸻
NIP-A5 — Programs
WASM binaries signed by developers, published to relays, executed by any client.
No backend. No app store. The sandbox is the platform.
⸻
NIP-C8 — Websites
Files hashed, manifest signed, fetched and verified by clients.
No “trust this server.” Sites are published, not hosted.
⸻
Why it matters
Nostr = identity + distribution + executable content.
IPFS + Ethereum tried this; now it works with just keys + relays + WASM.
No tokens, no gas, no consensus overhead.
⸻
The web was programmable at the edges. Then it centralized.
Now: clients run code, relays distribute, users own the keys.
We’re building a verifiable, executable web

Everyone’s talking about “agentic AI,” but here’s a real use case for builders.
Analytics is still painfully manual—whether it’s Google Analytics or Plausible.
Then I tried PostHog.
One command:
npx -y @posthog/wizard@latest --region eu
With Anthropic’s Claude, it:
• Understands your code
• Adds event tracking automatically
• Sets everything up
No manual tagging. Just useful analytics.
This is what AI should be:
→ Understand your product
→ Integrate itself
→ Deliver real value
Not hype—actual leverage.

BitLasso is live !!!
When I founded HexQuarter, I wanted to build something beyond a engineering firm.  I wanted a circular economy with the clients I work with.
The idea was simple: every payment becomes a receipt minted as a token.  That token has real value — it can be redeemed for discounts on future projects.  The more a client works with HexQuarter, the more tokens they accumulate, the better their discount, the more incentive to keep building together.   A retention loop grounded in actual work done.
The scarcity of the token isn't arbitrary. I It's backed by a Proof of Work — a real project completed, a real payment made.  Value derived from work accomplished, not speculation.
But to make this work, I needed to accept Bitcoin. And every option was broken.
Custodial processors took a cut and held my funds.  Self-hosted nodes meant managing rates and invoicing manually.   There was no middle ground that was both sovereign and operational.
So I built it myself.
BitLasso started as a product for my own needs.  Then I realized the gap was bigger: there's no cheap, simple way for businesses to accept Bitcoin without giving up custody or paying % fees on every transaction.
So I made it ~$1.
Under the hood:
→ Payments settled over Spark/Lightning/Bitcoin L1 — non-custodial
→ Nostr , is the anchoring layer, with no database we control, completly decentralized
→ Loyalty credits are tied to your wallet (Spark BTKN tokens), not an account that can be deleted
This is what Bitcoin-native commerce looks like.  Not a crypto wrapper on the same old stack.
If you're a business done trusting intermediaries — or a developer curious about what building on Bitcoin actually looks like — come take a look.

Nostr is a powerful engineering tool for modern decentralized apps.
I’ve been exploring this technology to create apps that last—reducing the need for backend servers, whether for persistence, communication, or synchronization layers.
This is underestimated.
It’s too often framed as just a social network, but it goes far beyond that.
There is so much potential.
For example, we often have to deal with authentication. With Nostr, you can replace that with public key authentication—no more JWT, OAuth, etc.
What about settings and customization across systems or apps? You can build that with Nostr as well. It’s as simple as publishing events—completely under your control and decentralized.
Need a notification system? No more SMTP to configure, push services to maintain, or other infrastructure. Just push messages to a user’s Nostr profile—directly to their mailbox and without censorship.
Want to reduce your storage dependencies and improve persistence fault tolerance? Write your data to Nostr relays and benefit from strong redundancy, auditable authorship, and cryptographic trails.
Let users bring their own feed into your app. Let them tip other users with Bitcoin over Lightning.
As you can see, many aspects of modern apps can be addressed through strong and efficient decentralization—without necessarily relying on full Web3 or blockchain protocols.
But when you combine Nostr with those technologies, it becomes a nuclear power source for your apps.
Let me know if this is of interest to you. I’m dedicating a major branch of HexQuarter to Nostr’s decentralized capabilities, and I would love to hear your feedback.
Go beyond traditional ideas and disrupt your industry.

Expert Take: 10 Years in the Bitcoin Ecosystem
A decade in this industry sharpens your lens.
Crypto developers are fleeing to AI.
The numbers don’t lie: -8 points of active blockchain devs in 2025, GitHub commits down ~75%, and over $270B in VC flowing toward AI versus $49.75B for crypto. LinkedIn’s fastest-growing roles? All AI.
I’ve watched this pattern before. A wave of developers drawn by opportunity — then gone just as fast.
This exodus isn’t a mystery. It’s the reflection of a short-termist approach, dictated by trends rather than conviction.
But for those who are deeply aligned with the values of freedom, transparency, fairness, censorship resistance, and sound money — there is no better sector to build a lasting legacy in.
They say it takes 10 years to truly master a domain.
The “snake” strategy — slithering from trend to trend — can generate quick wins. But it builds nothing solid.
I chose the long game. Human and societal values. The conviction that technology can genuinely liberate the individual — during our brief time on this earth.
Not the trend.
Not the opportunity of the moment.
Proud of these 10 years.
Proud to keep building.

Lessons from a Decade building on Bitcoin & Decentralized Protocols
1️⃣ Self‑custody isn’t an afterthought – it’s the core security model
- Design every component assuming the user holds the private keys.
- Eliminate hidden custodial layers; expose clear key‑management flows and recovery paths.
2️⃣ Unilateral exit must be baked in, not bolted on
- On‑chain settlements and Lightning withdrawals should be executable by a single party without third‑party approval.
- Expose an immediate on‑chain close or Lightning force‑close, preserving funds even if the service disappears.
3️⃣ UX = abstraction of complexity, not removal of it
- Hide protocol jargon behind intuitive actions while keeping the underlying guarantees visible in the UI for power users.
- Provide progressive disclosure: basic flow first, advanced settings on demand.
4️⃣ Security is non‑negotiable
- Threat‑model from day 0: key leakage, replay attacks, fee‑sniping, and network partitioning.
- Adopt formal verification where feasible (e.g., script validation, channel state machines).
- Run continuous fuzzing and audit pipelines; treat every new dependency as a potential attack surface.
5️⃣ Assume the network will fail – design for fault tolerance
- Graceful degradation: fallback to on‑chain paths when Lightning nodes are unreachable.
- Stateless services where possible; store only immutable transaction data.
- Redundant routing and multi‑path payments mitigate temporary topology failures.
Bottom line: Build for self‑custody, unilateral exit, and inevitable network disruptions.
Simplicity in the UI masks the rigorous, fault‑tolerant architecture underneath—because security and resilience are the only things that survive the long run.

2026-02-02 10:17:37 CET

I’ve spent a long time in this space, and one thing is clear to me:
Bitcoin didn’t “fix money.”
It fixed something more specific — the need to ask permission to settle value.
Every system before it broke at the same point: someone had the final say. And final say always turns into leverage.
Bitcoin changed the incentives.
Control became fragile.
Censorship became costly.
But that’s just one layer. Governance, credit, RWAs, stablecoins — those still need serious engineering.
The next decade won’t be about BTC vs fiat.
It’ll be about permissioned systems vs protocol-native ones.
That’s where the real work is.

Bitcoin attracts everyone — speculators, hedgers, true exit-seekers.
Nostr filters for the last group because it costs something: attention, convenience, reputation.
Most aren’t ready to pay that price yet. That doesn’t make them wrong — just earlier in the funnel.

Scripture already named this pattern: when man forgets he’s made in the image of God, he’s invited to live beneath it.
Dehumanization always begins inward — first we deny the soul, then we justify the cage.
The hope is this: men can still choose repentance over regression, order over chaos, creation over appetite.

The risk is becoming bigger and bigger in EU, since France passed a bill to ban social media for teenagers and hence will impose an identification control to access those!
Nostr will become the defacto,lasting freedom only social media

2026-01-27 15:01:31 CET

French lawmakers just passed a bill that would ban social media by under 15s.
This raises a lot of concern, as this comes perfectly with the agency of next presidential campaign starting in the next September 2026, the same date as the bill's application date. Strange timing...!
Thing is to ban social media for teenagers, this will require massive identification either through AI, identity method (KYC like), trusted certification issuers.
The problem is even bigger as this will not only check ID of teenagers but every French citizen to make sure they will be above the age.
IMO, everything is in place to prevent foreign interference for the election campaign, and shut the most freedom network and go in the censorship.
Fortunately, Nostr is there, completely decentralized, free, p2p.
This will become the only alternative long term for freedom of speech and opinion.

2026-01-23 18:56:23 CET

Bitcoin is powerful not because it can change — but because it refuses to break.
Its real innovation isn’t speed, features, or flexibility. It’s constraint.
It has a powerful execution layer because it enforces what must last.
Not flexibility. Not velocity. Determinism.
Every serious execution environment needs hard guarantees:
- Supply cannot be altered
- Past state cannot be rewritten
- Rules cannot be hot-patched under pressure
Bitcoin provides these at the base layer.
Fixed supply is not an idea — it’s enforced by consensus.
Immutability is not a promise — it’s verified by every node.
Monetary policy is not governance — it’s execution.
This is why Bitcoin works as a settlement and execution anchor.
You can build faster systems on top.
You can add expressiveness off-chain.
You can optimize UX, throughput, and latency.
But the execution root stays boring, slow, and extremely hard to change.
That’s the point.
At the base layer, innovation is risk.
Stability is the feature.
Bitcoin doesn’t maximize what you can do.
It minimizes what cannot happen.
And that’s why everything else can safely execute on top of it.

I’ve been thinking recently how Lightning became an interoperability layer for Bitcoin apps.
It can been seen as a common language, a share gateway for Bitcoin apps to communicate.
Whether you are building on state chains, or other l2 network solutions.
It allows apps to pick to right tool and build your own infrastructure, make liquidity and scalability way more easier, without blocking your funds and your tech debt into an ecosystem.
Really bullish how lightning can scale and bring way more usage to deliver awesome new Bitcoin usage and adoption.

Most people “learn blockchain” by reading.
I learned it by building apps… then protocols.
And once you’ve built blockchains from the inside, you stop falling for hype.
That’s how I ended up in Bitcoin.
Not because it’s trendy — because it’s engineered to survive reality.
Build > narratives.

Still impressed how deep Bitcoin is in terms of usage and ideas.
Discovered RWA started on 2012 with colored coins.
The hype we are seeing for the last 2 years about ETH and Solana is just marketing and ease.
But the real innovation came way earlier back then, with tokens backing bonds, NFT, shares, properties , etc…

2025-12-11 16:13:58 CET

People still think Bitcoin = money.
But they’re missing the real shift.
Bitcoin is becoming the most secure, censorship-resistant application layer in the world:
• Immutable data anchoring
• Tokenization with real settlement guarantees
• BTCfi without trust trade-offs
• L2s inheriting Bitcoin’s security
Ethereum got devs early. Solana got them fast.
Bitcoin is getting them right.
The “Bitcoin can’t do more” narrative is collapsing.
A new design space is opening—built on the strongest settlement layer ever created.
If you’re a founder or investor: look again at Bitcoin.
Innovation isn’t leaving. It’s coming home.

Most people still misunderstand Bitcoin smart contracts because they compare them to the EVM.
But Bitcoin never aimed for “maximum expressiveness.”
It aimed for maximum reliability — and that leads to a completely different category of financial engineering.
The surprising truth:
Bitcoin already powers smart-contract-like systems used in custody, marketplaces, asset issuance, governance, and BTCfi — just built with tools optimized for safety, auditability, and long-term resilience.

2025-12-04 20:04:42 CET

The Business Case for Bitcoin Infrastructure
Most companies still treat Bitcoin as an asset. Few see it for what it really is — a global, incorruptible infrastructure layer.
It’s the only network that’s survived 15 years of attack without downtime. No admins, no bailouts, no manipulation.
For businesses building on cloud platforms or permissioned chains, that’s a wake-up call: your trust is still rented.
Bitcoin lets you own it. You can anchor proofs, transactions, or agreements to a network that no single party can alter.
That’s not ideology — that’s a competitive advantage.
Because in a world of data breaches and compliance risks, provable integrity becomes a market differentiator.
👉 If your business depends on trust, start treating Bitcoin as infrastructure — not speculation.

2025-12-03 19:22:42 CET

Tokenization on Bitcoin isn’t hype — it’s finally real.
Most people still think “tokenization” = alt L1s.
Meanwhile, Bitcoin has quietly built the strongest rails for issuing and moving real assets:
• Taproot Assets → Lightning-native stablecoins + RWA
• Spark BTKN → enterprise-grade issuance + APIs
• Stacks FT/NFT → programmability anchored to Bitcoin
• RGB → client-side validated assets (private, scalable)
• Ordinals → indexing + metadata layer powering registries & proofs
The infrastructure is here.
Stablecoins, identity, registries, RWA… all doable on Bitcoin today.
Bitcoin won settlement years ago.
Now it’s winning issuance — and the market hasn’t woken up yet.

⚡️ Lightning isn’t dead. It’s becoming the interoperability layer Bitcoin actually needed.
Statechains like Spark and Ark are rising fast.
Each with different trade-offs.
Each powerful on its own.
Lightning is the glue:
message bus, liquidity fabric, exchange layer.
Statechains specialize.
Lightning connects them.
This is Bitcoin scaling like the internet — not a monolith.
