SLIPs
A repository of technical specifications and standards for SatoshiLabs projects, extending the Bitcoin Improvement Proposal process.
What is SLIPs?
SLIPs (SatoshiLabs Improvement Proposals) is a repository of technical specifications and standards for SatoshiLabs projects, extending the Bitcoin Improvement Proposal (BIP) process. It documents features and decisions related to hardware wallets, key derivation, encryption, and cryptocurrency interoperability that fall outside Bitcoin's scope. The project provides a formalized way to propose, review, and maintain standards used in tools like Trezor and other cryptocurrency ecosystems.
Cryptocurrency developers, hardware wallet engineers, and blockchain protocol designers who need standardized specifications for key management, security, and interoperability beyond Bitcoin's BIPs.
It offers a curated set of community-reviewed standards that address gaps in existing cryptocurrency proposals, with a focus on practical implementation, security, and hardware wallet integration, backed by SatoshiLabs' expertise.
Overview
SatoshiLabs Improvement Proposals
Use Cases
Best For
- Implementing standardized key derivation methods for HD wallets
- Designing secure encryption protocols for cryptocurrency metadata
- Developing interoperability standards for hardware wallets
- Referencing registered coin types and address formats in blockchain projects
- Creating shamir backup schemes for mnemonic seeds
- Building tools that require deterministic cryptographic hierarchies
Not Ideal For
- Projects exclusively focused on Bitcoin core development without hardware wallet integration
- Teams preferring informal, agile documentation over formal standardization processes
- Developers needing standards with broad, multi-vendor adoption beyond SatoshiLabs' ecosystem
- Applications requiring rapid iteration on cryptographic protocols, as SLIPs' review process can be slow
Pros & Cons
Pros
Each SLIP provides a concise technical specification and rationale, as stated in the README, ensuring precise implementation details for features like key derivation and encryption.
Extends the BIP process with proposals in states like Draft, Final, and Accepted, indicating thorough review and maintenance for security and interoperability.
Addresses gaps outside Bitcoin, such as hardware wallet security and metadata formats, backed by SatoshiLabs' expertise in tools like Trezor.
With proposals in various statuses (e.g., Active, Final) as shown in the README table, the repository demonstrates ongoing development and updates.
Cons
Primarily tied to SatoshiLabs projects like Trezor, which may limit applicability and adoption in broader cryptocurrency tools not aligned with their ecosystem.
The structured proposal states (e.g., Draft, Final) introduce bureaucracy, potentially slowing down the adoption of new standards compared to more agile approaches.
SLIPs focus on specifications without extensive examples or tutorials in the README, making direct implementation challenging for developers unfamiliar with the standards.
