Coinbase warns that Proof-of-Stake blockchains like Ethereumn (ETH) and Solana (SOL) could face risks from quantum computers in the future, following the announcement of the first report from an independent quantum advisory board on April 22.<\/span><\/p>\n

The report, conducted with researchers from Stanford, UT Austin, and the Ethereum Foundation, emphasizes that crypto remains safe from quantum for now, but preparation needs to start immediately before the threat becomes urgent \u2014 especially as the security structures of many blockchains could be affected if quantum computing capabilities reach a sufficiently strong threshold.<\/span><\/p>\n

Coinbase Flags Quantum Risks for PoS<\/b><\/h3>\n

Coinbase is not issuing an \u201cimminent threat\u201d style warning, but framing the issue in a long-term context. In a recent post, Philip Martin, Coinbase CSO, emphasized that \u201ccrypto is safe today,\u201d while noting that the industry needs to prepare before sufficiently powerful quantum systems emerge.<\/span><\/p>\n

Today we’ve published the first position paper from the Coinbase Independent Advisory Board on Quantum Computing and Blockchain, a group of leading researchers from Stanford, UT Austin, the Ethereum Foundation, and beyond.<\/p>\n

The short version: your crypto is safe today. But a\u2026<\/p>\n

This is the first report from the independent quantum advisory board established by Coinbase, with participation from researchers at academic institutions and the Ethereum Foundation. According to Coinbase, the group\u2019s goal is to assess potential risks to current cryptographic systems and propose long-term preparation directions for the industry.<\/span><\/p>\n

Research indicates that risk levels may vary between systems. Some blockchain protocols \u2014 especially Proof-of-Stake \u2014 may have a higher level of \u201cexposure,\u201d as the way public keys are used in the staking and validation process can increase exposure in certain attack scenarios.<\/span><\/p>\n

Why PoS Faces Higher Exposure<\/b><\/h3>\n

Unlike Proof-of-Work, where public keys are usually only exposed when a transaction is performed, Proof-of-Stake protocols require validators to maintain their public keys in a public state for long periods to participate in the validation process.<\/span><\/p>\n

This makes validators on PoS easier targets in a quantum computer attack scenario. If a sufficiently powerful quantum computer can derive a private key from a public key \u2014 an assumption related to the ability to break elliptic curve cryptography (ECDSA) \u2014 then the validator could become a direct target.<\/span><\/p>\n
