TEEs promised privacy by keeping data in hardware. A ten-dollar hack proved they were never fully secure. @ArciumHQ protects privacy with encrypted computing. Here’s how Arcium is different from TEEs. — ► What is a TEE? A Trusted Execution Environment (TEE) is hardware built to keep data safe inside a secure enclave. It was meant to provide privacy and integrity even when the machine itself could not be trusted.That promise made TEEs popular in crypto, where many projects used them for privacy. Examples: @intel SGX, Intel TDX, and @AMD SEV-SNP. — ► The TEEs Hack Story How the attack works: The exploit taps the memory bus to capture enclave memory, attestation keys, and other secrets. Cheap hardware records the traffic so data inside TEEs can be read. How it happens in practice: With physical access, an attacker fits a low-cost interposer on the memory bus, records traffic, and extracts keys. The tools are inexpensive and need only basic skills, so any node operator can be targeted. — ► Arcium’s Solution Arcium introduces Encrypted Computing, where data stays encrypted even while processed. This means no node ever sees raw data, removing the need to trust hardware. At its core is the Cerberus MPC protocol, which splits computation across many nodes. Privacy holds even if most collude, as long as one is honest. ➤ Distributed execution removes single points of failure. ➤ Far higher performance than ZK or FHE. ➤ Practical scalability for crypto and traditional industries. — Launching on @solana first but built for any chain, Arcium already powers dark pools and @UmbraPrivacy private transfers on testnet. With throughput far higher than ZK and nearly 1000x faster than FHE, it is positioned to be the privacy layer for crypto and beyond.

Also the next public testnet phase of @ArciumHQ just went live.

Arcium done right ';O

Privacy is the real challenge for chains
