- Upgraded w3up products to integrate & leverage ucan attestation support.
- Designed and spec-ed [access protocol](https://github.com/web3-storage/specs/blob/main/w3-access.md) allowing users to seamlessly access their capabilities across various agents / devices.
- Desigend and spec-ed [provider protocol]( https://github.com/web3-storage/specs/blob/main/w3-provider.md) decoupling user spaces from storage provides like web3.storage and nft.storage that get to be users of web3.storage
- Contributed to implementation efforts in w3up.
- Contributed to js-multiformats
- Championed and shipped `Link` interface to reduce library needed coordination across all libraries that use `CID`.
- Proposed and shipped better / human readable `JSON` serialization for CIDs.
- Co-authored [content-claims protocol](https://hackmd.io/@gozala/content-claims)
- Implemented [library for computing Piece CIDs a.k.a CommP in JS](https://github.com/web3-storage/data-segment) for w3up product
- Created extensive test datasets for conformance tests
- Identified problem with web-platform (preventing crypto-mining in browsers) and proposed alternative path forward
- implemented minimal effects support (from UCAN invocation spec) in ucanto library to enable their usage in w3up.
- Created and co-hosted "UCAN too" workshop at IPFS Thing to get more people familiar with UCANs
- https://github.com/Gozala/ucan-too
- https://observablehq.com/@gozala/ucan-too
- Shipped a major upgrade to ucanto wire protocol enabling multi-block responces, which was required to support signed receipts from UCAN Invocation spec.
- Implemnted content type negotiation system in ucanto allowing clients to specify desired content encoding (e.g CAR vs JSON) thorugh HTTP headers. This allowed seamless upgrade and backwards compatibility with older clients.
- Implemented & shipped signed receipt
- Implemnted support in ucanto library
- Implemnted changes across w3up to start issuing signed receipts.
- Upgraded ucanto and w3up libraries to adopt result types from ucan invocation spec.
- Implemnted backards compatibilility shim in ucanto for backwards compatibility with legacy clients expecting results in prior format
- Implemnted and shipped [blake3-multihash](https://github.com/web3-storage/blake3-multihash) library
- Co-authored [varsig](https://github.com/ChainAgnostic/varsig) specification which was originally desigend for [ucan-ipld](https://github.com/ucan-wg/ucan-ipld)
- Spec got adopted by ceramic
- Spec got adopted by UCAN invocation spec.
- Implemnted audience based routing in ucanto library, allowing clients to send invocations to different providers (e.g web3.storage or nft.storage) to a same endpoint.
- Enabling same user space to be used across providers.
- Contributed to UCAN log stream initiative
- Contributed to w3filecoin + Spade integration effort
## Other impact
- @ipld/unixfs got adopted by webrecorder project
- Represent and shared team work at UCAN Working group
- Represented and shared team at IPVM work week to ensure our alignment
