The MetaDAO Conference had such fresh energy to it. A ton of really cool conversations and ideas all centered around the future of better ownership
Umbra had a lot to share as well so you’ll probably see hints of some cool announcements that will trickle over the next couple weeks that we’ve been working towards for a while
Probably our biggest moment ever since the ICO🤝

Arcium just dropped Blackthorn, Encrypted Superintelligence.
It's their confidential AI protocol built on top of the @Arcium MPC network.
The goal: real-time, trustless encrypted inference and training at frontier scale, where sensitive data stays encrypted the entire time during processing, not just at rest or in transit.
This is the missing piece for AI that can actually touch data nobody is allowed to see in the clear.
Where Blackthorn matters most:
❶ Confidential inference on private inputs
Run queries on powerful models with complete privacy, no one sees your prompt or output. Ideal for medical, legal, trading, or internal strategy work.
❷ Encrypted training on pooled sensitive data
Hospitals can jointly train oncology models and banks can share fraud and risk signals, all without exposing raw data. That’s federated learning with cryptographic guarantees, not hardware trust.
❸ Protected model weights
Model owners can offer inference-as-a-service without leaking their IP. The weights stay encrypted even while running on someone else's GPUs.
❹ Agentic AI that can hold secrets
As agents move money, hold credentials, and act autonomously, they must use private keys and sensitive data without any single operator being able to extract them, one of today’s biggest stack gaps.
❺ Private on-chain AI
Verifiable AI outputs feeding DeFi protocols, confidential oracles, or ML-driven matching engines, where the inputs must remain sealed end-to-end.
This means Blackthorn turns the world's existing GPUs into one decentralized encrypted supercomputer. No new hardware required. Just math that no single company controls.
This is the infrastructure layer that finally lets private, sovereign, and agentic AI move beyond hype and into real production use cases.
In 2024, Arcium acquired its largest enterprise competitor developing the most performant confidential AI protocol on the market
In 2025, Arcium was accepted into the NVIDIA Inception Program
AI has always been a core part of the vision.
Arcium Blackthorn™ will make it real.
arcium's ZINC product hit #3 in solana protocol revenue. 1.5m confidential computations already processed on mainnet. network fees paid in SOL, 70% to operators, 20% to recovery nodes, 10% treasury. then they acquired Inpher to bring encrypted AI compute in-house. coinbase added ARX to its asset roadmap the day after TGE. the privacy infrastructure layer for solana's tokenized equity stack is already generating revenue before most people even know what MPC execution environments are
