📢 Rdv le 10 juin

Les retours de nos premiers testeurs nous permettent d'améliorer encore Référendum Citoyen avant son ouverture au public.

Nous avons choisi de consacrer quelques jours supplémentaires aux derniers ajustements.

📱 Le 10 juin sur l'App Store et Google Play.

x402 lets AI agents pay.

x402B asks the better question:

what happens when the seller does not deliver?

Payments are easy. Trust is the hard part.

@BosonProtocol is not just building payment rails for agents.

It is building the escrow layer for the agent economy.

[Boson @BosonProtocol]

What can you do with x402B?

Digital goods: APIs, datasets, software, licences.
Knowledge work: designs, contracts, deliverables.
Physical goods: real-world logistics.
High-value assets: tokenised RWAs.

@idrissaberkane Pourquoi même considérer que le minage de bitcoin "consomme" de l'eau. Les molécules d'eau servant au refroidissement ne sont jamais transformées. Elles restent telles quelles H2O. Simplement sous forme de gaz dans l'atmosphère et non plus liquide.

We're building x402B: the secure commerce infrastructure for the Agentic Economy.
Extends x402 to trust-minimized commerce — for any asset, any value, any counterparty.
x402B Build Update:
✓ MVP code complete
✓ E2E tests in motion
→ Next: deploy to testnet
✓ On schedule

[Ludovic Levalleux @levalleux]

@anatolium Je suis d'accord avec l'ensemble du programme, sauf un point: votre moustache sur l'affiche. Peut-être ce n'est que moi ?...

[Boson @BosonProtocol]

Eight years ago we built decentralized commerce infrastructure for an economy that didn't exist yet.

The agent economy just arrived.

Boson found Agent Market Fit. With x402B.

Announcing x402B

x402 + security = x402B

Extending x402 from trusted sellers and microtransactions to any asset, any value, any vendor.

The secure commerce layer for the agent economy is live.

What happens in @virtuals_io ERC-8183 if the evaluator just... does nothing?

The provider delivers work. Gets nothing.
The client gets the work AND a full refund.

The rational equilibrium is non-completion.
The protocol literally rewards inaction 🤯
Article 2 breaks this down

@BosonProtocol — The Decentralized Commerce Layer of the Intelligent Economy

[Boson @BosonProtocol]

[Boson @BosonProtocol]

We’ve analyzed @virtuals_io’s ERC-8183 "Agentic Commerce Protocol."

Our Verdict: 2/10

It is Not agentic — there's nothing agent-specific in it. It's a basic 3-party escrow.

And Not commerce — no commerce logic at the protocol level. All of that is left to whoever builds on top.

What's left is a naive escrow with serious game-theoretic problems:
1. Evaluator gets no payment — most powerful role, no skin in the game
2. Evaluator inaction — provider loses everything, client gets free work
3. Buyer selects the judge — self-evaluation, collusion, negligence all trivial
4. No optimistic fulfillment — requires an evaluator on every transaction
5. Capital lockup griefing — a single agent can DoS the ecosystem for gas fees
6. Reputation is the only defense — an unsolved problem. Farm fake rep, steal big, walk away.

At @BosonProtocol we used the world's best game theorists and devs to solve exactly these problems and create the decentralized agentic commerce protocol for the Intelligent Economy.

Here is the First Article: Debunking ERC-8183: Not Agentic, Not Commerce:

Ce qui est en jeu, c’est notre souveraineté alimentaire : notre sécurité à tous. Rappelons que la viande comme le lait sont sans danger pour l’être humain dans cette épidémie.

Ce qui est en jeu, c’est la fin du modèle qui repose sur la mise sous tutelle administrative des professionnels alors même que tous les syndicats agricoles sont d’accord pour un protocole sanitaire - comme si les professionnels de notre pays étaient moins responsables et moins compétents que la caste des hauts fonctionnaires - disposant de moyens quasi militaires.
Ce qui est en cause, c’est une culture du mépris qui n’est plus tolérée par notre société.
Nous ne sommes plus des #gueux

[Boson @BosonProtocol]

Unlike centralized platforms with extraction imperatives, our decentralized architecture prevents platform abuse through community governance.

There's no centralized entity that can change the rules, increase fees, or discriminate against users.

This isn't a promise. It's code.

The decentralized commerce layer of the human-AI economy.
