[rphmeier]

I'm Robert Habermeier, one of the co-founders of Polkadot.

My contributions in architecture and implementation comprise implementations of BABE, GRANDPA, and Parachain consensus logic. I've built teams, mentored new joiners, and written and reviewed quite a lot of code over the past 5 years of Polkadot.

For that reason I request the rank of "Grand Architect".

Notable contributions:

• First Commit to Substrate (initially was the Polkadot repo): paritytech/substrate@0d26ee7
• GRANDPA implementation
  • Vote Graph and GHOST-hunting paritytech/finality-grandpa#1
  • Vote accumulation and round-estimate logic paritytech/finality-grandpa#2
  • Voting + round-change paritytech/finality-grandpa#8
  • count equivocations on all votes paritytech/finality-grandpa#36
  • Initial GRANDPA integration paritytech/substrate#866
  • Dynamic authority sets in GRANDPA paritytech/substrate#1014
• BABE implementation
  • Fixing BABE epochs to change between blocks paritytech/substrate#3583
  • Generic authorship and uncle inclusion module paritytech/substrate#2941
• Slashing/Staking
  • Slash and prove membership of prior sessions paritytech/substrate#2970
  • safe multi-era slashing for NPoS paritytech/substrate#3846
• Parachains
  • (100ks of words in GitHub issues, parachain implementer's guide, etc)
  • Some key PRs
  • Implement the Statement Distribution Subsystem paritytech/polkadot#1326
  • Implement Network Bridge paritytech/polkadot#1280
  • Implement PoV Distribution Subsystem paritytech/polkadot#1344
  • Implement Runtime APIs paritytech/polkadot#1411
  • Candidate Validation Subsystem paritytech/polkadot#1432
  • Approval Distribution Subsystem paritytech/polkadot#1951
  • Implement Approval Voting Subsystem paritytech/polkadot#2112
  • Approval Voting Database paritytech/polkadot#2162
  • Dispute Coordinator Subsystem paritytech/polkadot#3150
  • Chain Selection Subsystem Logic paritytech/polkadot#3277
  • Prospective Parachains Subsystem paritytech/polkadot#4913
  • New parachain runtime skeleton paritytech/polkadot#1158
  • Scheduler Module paritytech/polkadot#1162
  • Inclusion Module paritytech/polkadot#1242
  • ...more

Beyond the code explicitly committed, I've reviewed code, filed issues, written blog posts at both a technical and vision level (https://polkadot.network/blog/polkadot-v1-0-sharding-and-economic-security/, https://medium.com/polkadot-network/grandpa-block-finality-in-polkadot-an-introduction-part-1-d08a24a021b5, https://medium.com/polkadot-network/polkadot-the-parachain-3808040a769a, and more), constructed the implementer's guide, done quite a lot of public speaking and education, and have effectively onboarded students of the guide, some of whom are now themselves qualified as architects.

I believe that I am well-suited to the rank "6: Grand Architect".
