EIP-1559

Definition ∞ EIP-1559, or Ethereum Improvement Proposal 1559, is a significant upgrade to the Ethereum network’s transaction fee mechanism. It introduced a base fee for each transaction, which is algorithmically adjusted based on network congestion and subsequently burned, removing it from circulation. Users can also include an optional “priority fee” to incentivize faster transaction processing by validators.
Context ∞ EIP-1559 is regularly featured in news concerning Ethereum’s economic model and its transition to a proof-of-stake consensus. Its implementation aimed to make transaction fees more predictable for users and introduced a deflationary pressure on Ether, altering the supply dynamics of the asset. The impact on validator revenue remains a topic of analysis.

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.
