Add OE system “roles” to FAQs about community-hub HOT 3 CLOSED

@TransmissionsDev My consolidation of your replies in discord:

Answers

1. Only authorized parties rn but eventually will be given permission via MEVA auction
2. Long term yes but u will have to win an auction
3. Anyone
4. Yes!
5. Sequencer gets ten fees, fraud provers get the bond of a lying proposer when they prove fraud.

Descriptions of roles

Sequencers

• Sequencer is chosen via a MEVA auction.
• Sequencer is a special user who gets the right to order transactions.
• Users can send their transactions to the sequencer and get a signed confirmation for instant inclusion.
• The sequencer submits a bundle of txs they have received every couple of minutes.
• They get tx fees from the transactions they bundle
• If a sequencer does not include a txn they signed and confirmed, a user can submit that signed confirmation to slash the sequencer's bond

Bonded Proposers

• A bonded proposer is usually the sequencer
• Anyone can become a Bonded Proposer by putting up some money as a bond, but the sequencer gets first priority.
• Bonded proposer looks at those bundles of txs and computes the actual ethereum state trie from the bundle and publishes the merkle root onto L1

Verifiers

• Anyone can be a verifier
• Verifiers also compute the actual state but are not looking to propose, they are looking to catch a bonded proposer who has lied about the correct state.
• If the verifier finds that a bonded proposer lied, they submit a tx to the L1 chain to have that transaction they believe is fraudulent computed and if the proposer was indeed lying, a portion of their bond (money they put up front) is taken away and given to the verifier. Some of the proposer's bond is burned in case the proposer is also the verifier.

Nodes

• Anyone can be a node
• Any node can recompute the state themselves (just like you would on L1)

Ayy!

Couple of nitpicks:

• "Anyone can be a node" is repeated twice in the Nodes section

their bond (money they put up front) is taken away and given to the verifier(edited)

• Remove the (edited) heh
• And only a portion of the bond is given to the verifier. Some of it is burned in case the proposer was himself also the verifier.

• Maybe mention that if the sequencer does not include a tx they signed and confirmed, a user can submit that signed confirmation to slash the sequencer's bond

Otherwise this looks pretty good, make it a PR?

this is quite stale and I believe that this documentation should get added with incremental smaller PRs.
I'll be closing this for now, but it will get solved as we expand the protocol and to;dr documentation.
