Private Stablecoin on Ethereum

In briefA proposal for a privacy-preserving stablecoin on Ethereum, backed by USDC/USDT

SummaryThis Ethereum Research forum post proposes a stablecoin protocol with built-in privacy, backed by USDC or USDT and leveraging Ethereum's programmability. It lists intended properties such as smart-contract-enforced minting and redemption, permissionless participation, composability with existing DeFi protocols, and confidential or unlinkable transactions. The author also outlines possible applications, including selective disclosure and private prediction markets.

BRO-AMM: A Bonded Reconciliation Oracle AMM as a Low-Risk DeFi Primitive

In briefBRO-AMM: a bonded oracle market maker proposal to reduce liquidity provider losses

SummaryThe author released an early preprint, BRO-AMM, addressing how arbitrage steadily drains value from liquidity providers in DeFi pools. The design makes trade prices final only after a later reconciliation step, with traders posting bonds and excess gains returned to depositors. A simulation replaying six months of ETH/USDC trades on Ethereum and Arbitrum reports lower depositor losses to arbitrage. The approach still relies on a trusted source of signed market prices and is not a live product.

Cassis, a new simple scheme for generic multi-layer multi-hop HTLC routing

In briefCassis: a simple scheme for generic multi-layer, multi-hop HTLC routing

SummaryBitcoin payments are spread across many layers, such as Lightning, Fedimint, Cashu and Arkade, with no generic way to pay between them. Cassis proposes that any layer able to express an HTLC can act as a hop, so a payment becomes a chain of HTLCs across layers locked to the same SHA-256 hash. An experimental Rust implementation exists, but open problems remain, including node communication, router announcements, reputation, invoice format and offline receiving.

Exposing an ISA for post-quantum proofs on Ethereum

In briefDiscussion on exposing an instruction set architecture (ISA) for post-quantum proofs on Ethereum

SummaryThis Ethereum Research forum post discusses how EIP-8288 could let transactions depend on post-quantum proofs verified outside the EVM. It compares three candidate instruction sets Ethereum could expose: the EVM, RISC-V, and a proving-oriented eISA. The author also explains how the exposed ISA could evolve without breaking immutable smart contracts.
