hbswap local devnet

[sbellem]

Issue to track progress for a local devnet, allowing to simulate a deployment and execution of hbswap.

By "local devnet" is meant that components that are assumed to be running on different hosts in a realistic deployment, can be run in a separate containers, and the overall network simulation can be run using a tool such as docker-compose, locally, on one computer.

The current work is under https://github.com/initc3/MP-SPDZ/tree/hbswap-devnet.

The sequence of events/processes that are run is:

# RUN private/local geth node, for development purposes
bash Scripts/hbswap/scripts/chain.sh

# deploy the contracts
go run Scripts/hbswap/go/deploy/deploy.go

# deposit funds
deposit 0 10 10

# preparation phase, in which shares are generated and written to file
# require a multi-party computation
# no interaction with ethereum
bash Scripts/hbswap/scripts/prep.sh

# HTTP servers for input masks
httpserver 0 &
httpserver 1 &
httpserver 2 &
httpserver 3 &

# MPC servers
mpcserver 0 &
mpcserver 1 &
mpcserver 2 &
mpcserver 3 &

# contract/ethereum interactions
secret_deposit 0 10 10
trade 0 1.1 -2.5
trade 0 -1.1 2
secret_withdraw 0 9 9
withdraw 0 9 9

Main components, to run in separate containers

ethereum specific

• geth node (local/private mode for now)
• contract deployer - deploys contracts to the chain
• initialization of funds / deposits

MPC specfic - setup & init phases

• "trusted setup" - generates keys for MPC nodes
• compilation of MPC programs, to generate the bytecode -- (although not essential for now, it is nevertheless isolated, because eventually, in future iterations, one can imagine that the bytecode could be generated on a separate machine, and deployed to an MPC network ...)
• Each MPC node for the preparation phase - initializing/writing shares to file

both ethereum & MPC

• HTTP servers
• MPC nodes

client

• python client code
• frontend handled in [WIP] HoneyBadgerSwap UI from Uniswap HoneyBadgerSwap#1

Notes about the frontend

It has a token list, that contains addresses for the nets (mainnet, testnet, ...)

Closing this as the work is now happening at https://github.com/initc3/HoneyBadgerSwap/pulls.
