Ethereum Proposes Deposit Contract Overhaul for Quantum-Proof Staking

Ethereum (ETH) Editor: Eugene Serbin

Decrypt.co reports that Ethereum developers have submitted a draft proposal to rebuild the deposit contract, aiming to prepare the network's staking layer for post-quantum cryptography. The current contract hardcodes BLS12-381 dimensions, fixing public keys at 48 bytes and signature metadata at 96 bytes, which leaves no room for larger post-quantum schemes. The replacement contract accepts keys and metadata up to 8,192 bytes and requires deposits to declare their credential scheme, with scheme zero reserved for BLS.

The contract operates in three modes: disabled, BLS enabled, and BLS retired, with retirement being irreversible. This change would require a coordinated fork across both the execution and consensus layers to take effect. One author, Thomas Coratger, highlighted the unsettled state of underlying cryptography in a Twitter thread summarizing a talk by Stanford cryptographer Dan Boneh.

Boneh noted that Bitcoin and Ethereum are heavily leaning toward hash-based signatures, with NIST-standardized versions running to roughly 8KB. Coratger stated that "Post-quantum cryptography isn't a simple upgrade," emphasizing the complexity of the transition. A May report from Project Eleven estimated better than even odds of a machine breaking elliptic curve signatures by 2033, with 2030 as a possible earlier date. More than 65% of all ETH sits in addresses whose public keys are already exposed onchain.

Whalio spot data for Ethereum shows a price of $2,506.78 with a 24-hour buy ratio of 51.2%, indicating a slight majority of buying pressure over the day. The 1-hour buy ratio is 55.0%, suggesting immediate buying interest is stronger than the daily average, while the 4-hour ratio of 40.4% shows recent momentum has weakened. The 24-hour volume delta is positive at $14,758,006, meaning net buying has outweighed selling over the full day. However, the 4-hour volume delta is -$11,321,838, indicating that selling pressure has dominated the most recent trading window. The 1-hour volume delta is +$7,944,358, showing that buying has resumed in the last hour. CVD closed at +$18,069,472, confirming that cumulative buying has exceeded selling over the 24-hour period.

The latest daily buy ratio of 46.8% sits at the 16th percentile of the last 322 days, against a median of 49.5% - weaker buying than most days.
