Request to join the fellowship
## Presentation Hello, I am Guillaume Thiolliere, worked at parity in 2019-2022 and from september 2024. I worked mainly on the runtime part, in FRAME and its pallets. ## Details - Github: https://github.com/gui1117, formerly https://github.com/thiolliere - Matrix: @guillaume:parity.io, formerly @gui:parity.io - Polkadot address: 13psJuWEjBuZGaFqXvFnLMC6ME8RVVfQAhtFhydYjW45oKgZ - Area(s) of Expertise/Interest: - polkadot business-logic (aka the 'runtime') - the internals of the frame pallet framework - runtime and host APIs ## Some past work: 2019-2022: * Authored the FRAMEv2 pallet macro. Updating from `decl_module!` to `#[pallet]` macro. * Designed instantiable pallet concept. * Implemented the elision of pallet parts in `construct_runtime`. * Iterable storage (without linked list) ## Recent work: * FRAME: Fix tasks for instantiable pallets: https://github.com/paritytech/polkadot-sdk/pull/5194 * frame pallet: fix calculation when underestimating refund in storage weight reclaim: https://github.com/paritytech/polkadot-sdk/pull/5273 * various comments and contribution in the transaction extension PR: https://github.com/paritytech/polkadot-sdk/pull/3685 * The PR was missing the pipeline for bare extrinsics, so weight wasn't checked nor registered for bare extrinsics * Subtle comments like `CheckNonce` prepare was overriding the whole storage item with value coming from validate, potentially erasing other change in the account storage. * The pipeline was made to allow multiple version of transaction extension but there was no plan to make the version part of any signed payload. * Currently implementing the next step of the transaction extension horizon: https://github.com/paritytech/polkadot-sdk/pull/6324 * improve the precision of benchmarks for system chains, potentially resulting in better resource usage of the system chains. https://github.com/polkadot-fellows/runtimes/pull/525 * Many PR review in polkadot-sdk.

Add Vincent Geddes as DAN II
# Fellowship application for Vincent Geddes # Details Matrix username: [@vgeddes](https://collectives.polkassembly.io/user/vgeddes):matrix.org Github: [https://github.com/vgeddes](https://github.com/vgeddes) Mail: [email protected] Polkadot address: 16YdterMH6axUsZP52fF3M7JJePfNB3yCd8dXwniEofpTSiP # Motivation I have been part of the Polkadot community since 2020, leading the effort to build and deliver Snowbridge, a trustless and decentralized bridge between Polkadot and Ethereum. This is a major system compromising many different subcomponents spread over multiple chains, including AssetHub, BridgeHub, and Ethereum. Snowbridge is active and is currently holds over $80 million in bridged assets. In terms of user traction, It is a key component allowing the Mythos and KILT chains to deliver their products. Integrations with other parachain systems are in development. Joining the fellowship will allow me to more effectively participate in fellowship governance topics related to trustless bridges. I would like to apply for the *Dan II* level as I believe I have fulfilled the necessary requirements: * I am the primary individual responsible for the technical development and delivery of Snowbridge. Many teams of course contributed to its delivery. * I am deeply familiar with: * Trustless bridging protocols, design, and implementation * BEEFY consensus protocol * XCM, XCM Executor, and ongoing XCMv5 development * I have published a long-form technical article about Snowbridge: * [https://docs.snowbridge.network/architecture/overview](https://docs.snowbridge.network/architecture/overview) * I developed the reference implementation for a system that is described in a [paper](https://research.web3.foundation/assets/files/beefy-83fa77754436908399299de4bf1310b6.pdf) by W3F and is currently pending submission to academic journals. # Contributions ## Random-sampling BEEFY client In collaboration with W3F (Alistair Stewart, Bhargav Bhatt), we designed a novel random-sampling light-client for the BEEFY consensus gadget. I implemented the specification, which today is powering verification of Polkadot→Ethereum messages for Snowbridge. * Code: [BeefyClient.sol](https://github.com/Snowfork/snowbridge/blob/20a804669e0da59cff01b09588e16f1267d98862/contracts/src/BeefyClient.sol) [[Blame](https://github.com/Snowfork/snowbridge/blame/20a804669e0da59cff01b09588e16f1267d98862/contracts/src/BeefyClient.sol)] * [Implementation Article](https://docs.snowbridge.network/architecture/verification/polkadot) * [Research Paper](https://research.web3.foundation/assets/files/beefy-83fa77754436908399299de4bf1310b6.pdf) ## Snowbridge BridgeHub Pallets Snowbridge includes several pallets that are currently operational on the BridgeHub system chain. Primary author: * [snowbridge-pallet-system](https://github.com/paritytech/polkadot-sdk/tree/master/bridges/snowbridge/pallets/system) * [snowbridge-pallet-inbound-queue](https://github.com/paritytech/polkadot-sdk/tree/master/bridges/snowbridge/pallets/inbound-queue) * [snowbridge-pallet-outbound-queue](https://github.com/paritytech/polkadot-sdk/tree/master/bridges/snowbridge/pallets/outbound-queue) Major contributor: * [snowbridge-pallet-ethereum-client](https://github.com/paritytech/polkadot-sdk/tree/master/bridges/snowbridge/pallets/ethereum-client) * [Primitive crates](https://github.com/paritytech/polkadot-sdk/tree/master/bridges/snowbridge/primitives) Note that these pallets originated in our separate team [repository](https://github.com/Snowfork/snowbridge), and were later [duplicated](https://github.com/paritytech/polkadot-sdk/pull/2522) into the Polkadot-SDK. As such, historical commit history was lost, and I won’t appear as a committer to the relevant files. Refer to this [snapshot](https://github.com/Snowfork/snowbridge/tree/ffe241f357ba234b68c33da1c9fcf4a92e277eae/parachain/pallets) to view the original pallets. For example, here is a [blame](https://github.com/Snowfork/snowbridge/blame/ffe241f357ba234b68c33da1c9fcf4a92e277eae/parachain/pallets/outbound-queue/src/lib.rs) showing my commits to the original inbound-queue pallet. ## Snowbridge Ethereum Contracts I designed and authored all the contracts on the Ethereum side of the bridge: [https://github.com/Snowfork/snowbridge/tree/main/contracts](https://github.com/Snowfork/snowbridge/tree/main/contracts) ## Snowbridge Off-chain relayers I am a major contributor to our off-chain relayers, which synchronize state between the BridgeHub and Ethereum: * BEEFY consensus relay * Beacon consensus relay * Polkadot user message relay * Ethereum user message relay [https://github.com/Snowfork/snowbridge/tree/main/relayer](https://github.com/Snowfork/snowbridge/tree/main/relayer) ## Snowbridge V2 More recently, a new version Snowbridge is under development, which makes use of XCMv5 to provide better UX and more features. As part of this effort, I am responsible specifically for: * The design [specification](https://github.com/paritytech/polkadot-sdk/blob/master/bridges/snowbridge/docs/v2.md) (along with major contributions from Alistair Singh, Adrian Catangiu, and Francisco Aguirre) * The ethereum contracts: [https://github.com/Snowfork/snowbridge/pull/1300](https://github.com/Snowfork/snowbridge/pull/1300) ## XCMv5 Along with my team, I helped review the ongoing XCMv5 development effort. The Parity XCM/Bridges and Snowbridge team met up in September 2024 in Berlin to finalize XCMv5 requirements, among other things. As one of the outputs of this retreat, I wrote up a semi-formal [specification](https://github.com/paritytech/polkadot-sdk/blob/master/bridges/snowbridge/docs/v2.md) for Snowbridge V2, which relies heavily on XCMv5, and helps validate its design with an actual user-facing project. Other contributors to this document included Alistair Singh, Adrian Catangiu, and Francisco Aguirre. ## Miscellanous * Minor contribution to pallet-assets: [https://github.com/paritytech/substrate/pull/9742](https://github.com/paritytech/substrate/pull/9742) * Minor contribution to XCMv4: [https://github.com/paritytech/polkadot/pull/6286](https://github.com/paritytech/polkadot/pull/6286) * Utility pallets: * Snowbridge governance CLI: [https://github.com/Snowfork/snowbridge/tree/main/control](https://github.com/Snowfork/snowbridge/tree/main/control) ## Governance I created a successful OpenGov [proposal](https://polkadot.polkassembly.io/referenda/680) to activate Snowbridge. This was a complex proposal that orchestrated changes on multiple chains, including AssetHub, BridgeHub, and Ethereum.
