This is our current development Roadmap as of the end of Q1 2021. The exact amount of progress on this Roadmap is dependent in part on funding levels from various Sustaining Patrons as well as Sponsors for specific projects. Contact Christopher Allen [ChristopherA@BlockchainCommons.com](mailto:ChristopherA@BlockchainCommons.com) if you are interested in supporting one of these projects. ## Recent Development Cycles Blockchain Commons came fully online in 2020 and has produced quarterly reports of its progress in [Summer 2020](https://www.blockchaincommons.com/quarterlies/2020-Q3-Report/), [Fall 2020](https://www.blockchaincommons.com/quarterlies/2020-Q4-Report/), and [Winter 2021](https://www.blockchaincommons.com/quarterlies/Q1-2021-Report/). Our most notable accomplishments over the last year include: **Developer Community:** Developed an active [Airgapped Wallet Community](https://github.com/BlockchainCommons/Airgapped-Wallet-Community/discussions) support wallet interoperability specifications; multiple companies have joined. Blockchain Commons joined [COPA](https://www.opencrypto.org/) ([announcement](https://www.blockchaincommons.com/partnerships/BCC-Joins-COPA/)) to support open access to patents. Graduated our [first class of summer interns](https://www.coindesk.com/blockchain-commons-interns-open-source-developers). **Research:** Oversaw the development and expansion of our [Universal Resources](https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-005-ur.md) for [many cryptographic data types](https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-006-urtypes.md), and most recently developed a [request/response system](https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2021-001-request.md). Developed [Lifehash](https://github.com/BlockchainCommons/LifeHash) to visually identify cryptocurrency accounts and the [Torgap architecture](https://github.com/BlockchainCommons/torgap) to protect privacy and defeat correlation. Worked with sustaining patron [Bitmark] (https://bitmark.com/) to architect a multisig solution for their upcoming Autonomy bitcoin wallet. **Development:** Released: our [crypto-commons reference libraries and cli utilities](https://github.com/BlockchainCommons/crypto-commons); our initial [Gordian reference utilities](https://github.com/BlockchainCommons/Gordian) such as [Gordian Wallet](https://github.com/BlockchainCommons/GordianWallet-iOS), [Gordian Server](https://github.com/BlockchainCommons/GordianServer-macOS), [Gordian Cosigner](https://github.com/BlockchainCommons/GordianCosigner-iOS), and [Gordian Guardian](https://github.com/BlockchainCommons/GordianGuardian-iOS); our [LetheKit](https://github.com/BlockchainCommons/bc-lethekit) DIY hardware kit; and our [Spotbit pricing server](https://github.com/BlockchainCommons/spotbit). A number of these tools have been ported to other languages by the Airgapped Wallet Community. **Documentation:** Published [Learning Bitcoin from the Command Line 2.0](https://github.com/BlockchainCommons/Learning-Bitcoin-from-the-Command-Line) and expanded our [Smart Custody work](https://www.smartcustody.com/) with ["Designing Multisig for Independence & Resilience"](https://github.com/BlockchainCommons/Gordian/blob/master/Docs/Multisig.md). **Advocacy:** Testified in Nevada, North Carolina, and Wyoming. Christopher led subcommitee in Wyoming pass a bill to [define digital identity](https://wyoleg.gov/Legislation/2021/SF0039), and was member of another team that helped pass a bill for [DAO based LLCs](https://wyoleg.gov/Legislation/2021/SF0038). Did not succeed in passing bill given special protection to private keys. ## Current Cycle (Planned & Funded) This listing includes our top priorities for the current cycle, based on current funding levels. **Developer Community:** * **Gordian Seal.** _(Project sponsor: Bitmark)_ Finalize a [Gordian Seal](https://hackmd.io/KFIw-SUnRGyv3A8c6VpTXQ) program for Bitcon wallet, and a Blockchain Commons [Code of Ethics](https://hackmd.io/SJbeoXaFScmGM4_-AmNZeQ). * **Increase Airgap Wallet Community Participation.** Get more companies to adopt UR, and participate in airgap and multisig wallet specifications and demos of interoperability. **Research:** * **UR Expansion.** Add more data types for Universal Resources as required by community. Account and policy maps, Quick Connect 2.0, add more examples of crypto-request and response, in particular related to PSBT and SSKR. * **SSKR Expansion.** _(Project sponsor: Bitmark)_ Expand SSKR recovery shards for use with more than 32 bytes of data, encrypted metadata, and more. Begin design for UR-based Encrypted CBOR. * **SSKR UX.** Resolve UX best practices for use of SSKR recovery shards. * **XPub Privacy.** Create best practices for avoiding current problem of reuse of xpubs in multisig wallets. * **Family Multisig.** _(Project sponsor: Bitmark)_ Explore best practices for familial multisigs and digital asset smart contracts for inheritance. **Development:** * **Gordian QR Vault.** Prepare QR Vault for release in Apple's app-store. * **Gordian Wallet/Server.** Modernize and update Gordian Wallet and Server, including integration of some new features available latest Bitcoin Core. * **Encrypted CBOR** _(Project sponsor: Bitmark)_ Develop reference tool for encrypted CBOR, for later use with UR, SSKR metadata and other scenarios. * **Sweep Tool.** _(Project sponsor: Bitmark]_ Develop command-line multisig sweep tool for use with descriptor-based multisig accounts, that can leverage Tor-based bitcoin explorers such as Esplora and Gordian Server. * **SSKR.** Acquire third-party security reviews for our SSKR and Shamir libraries. * **apt-get Integration.** Make our CLI tools available through `apt-get` in particular for Debian & TailsOS. **Documentation:** * **UR & Gordian Architecture.** Higher level intro/overview of UR and Gordian code and best practices for wallet developers.
