BitGo Just Ran Crypto’s First Quantum-Resistant Transaction Simulation

BitGo and Silence Laboratories completed the first post-quantum multi-party computation transaction simulation ever performed by a regulated custodian. The test used lattice-based cryptographic algorithms inside BitGo’s existing MPC wallet infrastructure. The timing matters because quantum computing threats to current encryption standards are no longer theoretical talking points; they are active engineering problems with budgets attached.

What Happened

According to the May 26 press release, the two companies ran a simulated transaction using post-quantum cryptographic primitives within a multi-party computation framework. MPC splits private keys into shares held by different parties, so no single entity ever controls the full key. The quantum-resistant layer adds protection against future attacks from quantum computers capable of breaking the elliptic curve cryptography that secures nearly every blockchain wallet today.

BitGo is one of the larger institutional custodians in crypto, and holds assets for exchanges and enterprises. Silence Laboratories specializes in MPC and cryptographic research. Their collaboration targeted a specific vulnerability in the form of the eventual ability of sufficiently powerful quantum machines to reverse-engineer private keys from public keys.

Why Custodians Are Moving Now

The National Institute of Standards and Technology (NIST) finalized its first post-quantum cryptographic standards in 2024. This lit a fuse under the entire financial infrastructure sector. Banks and custodians are all running assessments on how exposed their systems are to quantum threats projected to materialize within the next decade.

For crypto specifically, the risk is unusually direct. Public keys sit on open blockchains. Once quantum hardware reaches a certain threshold, any wallet whose public key is exposed becomes a target. Custodians holding billions in client assets can’t allow themselves to wait until the threat is imminent.

This simulation is a proof of concept, not a shipped product. But it sets a benchmark. Other custodians now face a concrete comparison point. Institutional clients allocating to digital assets will increasingly ask whether their custodian has a post-quantum migration plan. BitGo just made that question harder to dodge.
