On-Chain Auctions

Definition

On-chain auctions are bidding processes conducted entirely on a blockchain, where all bids, offers, and transaction settlements are recorded and executed via smart contracts. These auctions leverage the transparency and immutability of distributed ledgers to ensure fairness, prevent manipulation, and provide an auditable record of the entire process. They are commonly used for selling non-fungible tokens, digital land, or other crypto assets.
Time-Bound Schnorr Signatures Curb MEV, Restoring Transaction Predictability. A transparent blue polymer housing encases intricate metallic components, suggesting a specialized hardware interface. A slender metallic pin extends from a precision-machined connector, potentially facilitating secure data transmission within a decentralized network. This internal architecture could represent a secure enclave for private key management or a critical component in a blockchain node. The design emphasizes robust digital asset custody and cryptographic signature generation, vital for transaction validation and maintaining immutable ledger integrity in Web3 applications.

Time-Bound Schnorr Signatures Curb MEV, Restoring Transaction Predictability.

This research introduces time-bound Schnorr signatures, a cryptographic primitive that embeds an expiry block height directly into a transaction's signature, fundamentally altering MEV dynamics by restoring predictable transaction inclusion and reducing predatory extraction.
