WIP - Work in progress Note: Many thanks to Barnabé Monnot for reviewing, guidance, and providing feedback. Introduction In this post, we explore the intriguing world of edge cases within First Price Sealed Bid Auction (FPSBA) and Second Price Sealed Bid Auction (SPSBA) in Ethereum’s Proposer Builder Separation (PBS) scheme, where traditional...

Note: Many thanks to Barnabé Monnot for reviewing, guidance, and providing feedback. Introduction Ethereum’s shift to a Proof of Stake (PoS) consensus mechanism introduces a clear division of roles in block proposal and construction through the Proposer-Builder Separation (PBS) 12. This structure not only improves operational efficiency but al...

Overview Public blockchains like Ethereum provide an ideal infrastructure for the development and operation of AI agents, due to their distinctive features that align perfectly with the needs of decentralized, autonomous systems. These platforms not only support but enhance the capabilities of AI agents, fostering a new era of technological int...

In Ethereum consensus mechanism, it’s critical for all participating nodes to agree on the state of the system consistently and efficiently. The Simple Serialize (SSZ) framework facilitates this through Merkleization, a process that transforms serialized data into a Merkle tree structure. This wiki page discusses the intricacies of Merkleization...

Overview Simple Serialize (SSZ) is a serialization and Merkleization scheme designed specifically for Ethereum’s Beacon Chain. SSZ replaces the RLP serialization used on the execution layer (EL) everywhere across the consensus layer (CL) except the peer discovery protocol. Its development and adoption are aimed at enhancing the efficiency, secu...

Recursive Length Prefix (RLP) is a core serialization protocol used within the execution layer for encoding and parsing data. It is designed to serialize data and produce a structure readable by all client software. It is used for everything from transaction data to the entire state of the blockchain. This wiki page explores the internals of RLP...
