bullishPumped to be partnering with @Arcium on the launch of Blackthorn, their new private AI infrastructure. Always happy to help put a legit team in front of more people, so here’s a quick explainer on what they do and why it’s important.
Most private AI today runs your prompts on a GPU, with the keys to the GPU held inside a CPU enclave (a TEE). CPU enclaves work well for a lot of use cases, but they put all the trust in a single piece of hardware, and if that hardware is ever compromised, every prompt and output behind it can be exposed. For anyone who needs the strictest privacy guarantees, that’s a lot to rest on one point of failure.
Blackthorn takes the CPU TEE out of the trust chain and replaces it with MPC (multi-party computation). MPC splits a secret into pieces and hands each piece to a different party, so no single machine ever holds the full key. A reasonable analogy is a multi-sig vs a single-key wallet. One compromised party isn’t enough to bring the whole thing down.
MPC is Arcium’s bread and butter. Their network on Solana has already run around 3M encrypted computations, and their main MPC protocol is built so your data stays private as long as a single node in the group stays honest (rather than needing a majority).
This opens the door for anyone sitting on data too sensitive for regular AI. Hospitals, banks, governments, companies protecting their own models, etc.
They’re in private alpha for now, with access rolling out over the coming days, so I’ll be keeping an eye on them (and recommend you do too). Privacy and AI are arguably the two strongest narratives of this entire cycle, and Arcium is one of the projects with real tech in both.
