Alice (dApp) executes wraptokens on FIO chainCasey Gardiner Need brief overview of what is happening: which contract is used

Alice called wraptokens inside the fio.oracle contract.

Contract Actions:

• Paramater Validation ( ensuring amount, token codes, pubkey and fees are all properly set )

• Search oracle registration table and tally up the total number of registered oracles

• Collect Oracle fees, sort, and find the median.

• Send fee to all oracles.

• Emplace wrapping details inside the receipts table.

  Image Added

• Send the wrapped amount from Alice to fio.oracle contract.

• Collect BP fees

• Increase Alices RAM by 512.

• Send successful response to Alice

Oracle monitors wraptokens for transfers

Todd G What was the Go code doing to monitor the chain?

Oracle validates wraptokens transaction

Todd G Need bullet list of validations

If exceptions are found, Oracle takes action to unwind transaction

See Exception handling below

Todd G Need to flesh this out

Oracle executes wrap on Ethereum

Adam Androulidakis Need brief overview of what is happening: which calls are used. What needs to be passed.

Oracle validates wrap transaction

Todd G What type of validation is done on the Ethereum chain during a wrap?

Once all Oracles have submitted wrap, the wFIO Tokens will be minted and transferred to designated Ethereum public address

Todd G Does the oracle do any kind of monitoring or validation of the overall transaction (post consensus?)

Alice (dApp) executes unwrap on Ethereum chain

Adam Androulidakis Need brief overview of what is happening: which contract is used, when does the burn happen?

Oracle monitors unwrap for transfers

Todd G What was the Go code doing to monitor the chain? Does it confirm burn?

Registered Oracles will call upwraptokens inside the fio.oracle contract

Contract Actions:

• Paramater Validation ( min/max amount, fio address check )

• Verify the actor is a registered oracle

• Find the fio.address inside the fionames table

• Search for previous votes of the same obt_id

  • If found

    • Search and verify actor has not voted prior

    • copy vector and push account name to list of voted oracles to the vector of votes

    • modify voters table with new vector

  • If not found

    • add actor to new vector

    • emplace new record with voters information

      Image Added

• Compare number of votes with number of registered oracles

  • if number of votes equal the number of registered oracles, transfer amount from fio.oracle contract to the fio.address provided.

• Send successful response to the oracle
