Introduction

Gummiworm is a custody settlement protocol that enables fast-finality, high throughput, multi-chain and programmable decentralized custody of funds.

This whitepaper serves as a comprehensive reference for the single-headed Gummiworm protocol, along with a roadmap for future advancements.

It’s organized as follows:

• This section provides content for those who want to understand why Gummiworm exists and why you might want to build with it
  • Gummiworm describes the motivation behind the single-headed Gummiworm protocol
  • Sugar Rush describes a central limit orderbook built on top of Gummiworm, as a case study
  • Roadmap gives a high level overview of future improvements we have planned for Gummiworm
  • Results shows performance and cost results from our prototype and benchmarking
  • Comparative Analysis gives a comprehensive comparison between Gummiworm and other scaling solutions
  • Hydrozoa and Gummiworm describes how the two protocols evolved independently and converged into the design described in this whitepaper
• The Single-head Gummiworm Protocol serves as a comprehensive specification for the current version of Gummiworm
  • Replicated State Machine outlines the data model and state transitions of Gummiworm
  • Consensus outlines how a Gummiworm head makes decisions about which state transitions to apply
  • Peer network describes how peers in the Gummiworm network communicate
• Sugar Rush specifies how the central limit orderbook is architected
• Blockchain Specifics serves as a reference for how the connection to various L1s is achieved
• Future Work provides a much deeper exploration of planned future improvements, including the multi-headed version of Gummiworm
• Index of Terms serves as a reference for common terms throughout
