Goals
- Common understanding of Mercury and its requirements. Every one of us should be able to answer "what about... " questions with respect to Mercury if cornered.
- Identify major gaps in Documentation and make sure someone is assigned to resolve it.
- Do some coding together in Rholang. Write contracts.
...
- Support for transactions taking place between contracts in different namespaces
- How is the ledger maintained? reference: Blockmumble
- What are the canonical set of blocks that a validator has to download?
- CASPER - When do expect to have working code?
- What is the data structure.
- What are the networking requirements for the protocol?
- Is there a critical mass of validators that is required in order for a contract to be viable?
- Can a smart contract operate with a single validator?
- Do bounties need to be implemented in order to entice validators to come online?
- Cryptography:
- Identification of nodes by public key (or hash of public key (or hash of hash of . . .))
- Exchange of keys at handshake time
- Signing of messages
- Timm Schäuble: Capture requirements for Crypto op code(s) for VM (work with Kyle)
- Kyle Butt: Specify the Crypto that RChain will use.
Day 1: Location 3 - Verticals, Industries and Applications (Medha, Lawrence, Ed, Rolland, Navneet)
- Which industries are expressing interest & we should target?
- What are the use cases that are the most compelling for these industries?
- Which markets are we going to go after in these industries (Enterprise, mid-market, SMB, VSB)
- What is the TAM (Total Addressable Market)
- What is the story we can tell if these industries solve the use cases with blockchain?
- What are the applications do we see evolving as a result
- Medha Parlikar (Unlicensed): work with Lawrence, Ed and Rolland to document.
Day 1: Location 4 - Namespaces (Greg, Kent, Joe, Ian, Nash, Dan, Kyle)
- Lay out namespacing, How is the set of the namespaces going to be defined
- Who gets to say what a valid url is
- Is there a registry, what does it look like, when do we need to have it in place, how is it maintained
- Can we specify statically the form of name in a namespace, so we can check it at compile time
- How do we introduce new formats for names? urls are great but dont cover everything we might want
- How do we allow nodes to define their own grammar for names?
- Michael Stay (Unlicensed): Create a document about Namespaces that captures our current understanding, what they will look like, open questions and problems that still need to be figured out.
Day 2 Location 2: Rholang Lab (Greg, Timm, Ian, Navneet, Eitan, Kyle)
...
- Addressing shell games that amount to finding consensus assuming you have already got consensus...
- Betting requires fungibility between forks. How do we solve this in POS Consensus - what is the asset external to the system to create consensus?
- If we define consensus inductively, there is a time window over which a network split absolutely cannot happen. There is no value for this time window that makes network splits not happen.
- What happens when a validator leaves for several months and then returns - how is trust re-established without opening the network to attack?
- How do we address the problem with the first induction window, in which you cannot possibly have bonded validators, and you must fall back to centralized selection.
- Will increasing the induction time to 7 days resolve the problem.
- Do we have a solution to the Prisoner's dilemma? reference:
- Transaction receipts (in lieu of every validator validating every shard that shares cross-shard state) create a Prisoner’s dilemma. It doesn’t matter if you model the self-referential consensus-by-betting with the Pi calculus, because such a process model does not model such economically driven externalities.
- How does one identify the list of validators at any given time? (It's not clear to it will work as described, may simply need clarification)
How do we address double spend?
For the Mercury release do we plan to have our staking token implemented "natively" - specifically, such that we can do the equivalent of msg.sender.send(amount) in Ethereum? Or are we just going to use the token.rho contract for our staking tokens too?
- Michael Birch (Unlicensed) - Please look at the above questions and address as part of your documentation and work.
Day 2 Location 4: Business Requirements (Ed, Lawrence, Nash, Medha, Rolland)
- Are there special requirements for the wallet application for Mercury?
- Do we need MULTI-SIG support for Mercury
- Based on the industries and applications from Day 1 - define business requirements for the applications.
- Why do we want to integrate with BTC and ETH in time for Mercury (source: ECDSA Secp256k1 curve for BTC and ETH from WBS)
- What is not part of Mercury?
- What of Ethereum's road map? Do we address any of the items in Mercury?
- Medha Parlikar (Unlicensed): Work with folks to gain clarity and document.
Day 3: Location 2: Marketing Strategy (Ed, Lawrence, Nash, Medha, Rolland, Ian)
