This repository is workshop for sonm smart-contracts organisation.
See presale and token contracts here: (https://github.com/sonm-io/ico-contracts/blob/master/contracts/SNM.sol)
Contracts schematic could be found here : (https://github.com/sonm-io/Contracts-scheme)
You can get more detailed info about contracts [here] (https://github.com/sonm-io/Factory/tree/master/contracts)
Before hub started to payout tokens to miners and recive payments from buyers – he must create a hub wallet – simple contract with defined amount of frozen funds. If hub will be cheating – DAO could initiate process of blacklisting this hub and expropriate frozen funds from it.
Frozen funds it also will be frozen at DAO account for defined time – it's special protection against malicious descisions of DAO – tokens could lower it price for time from expropriation to undfreeze, therefore there is no motivation to 'raskulachivat'(expropriate) every hub.
Miner wallet is a simple contract which build by analogy with hub wallet - like employment history it could help to rate miners. freezePeriod for MinerWallet are much less, than for HubWallet.
Factory - is a simple factory contract, which can create wallets and have instruments for checking info about wallets creation (for approval of valid wallets contracts)
Whitelist containing info about registred wallets. All registred wallets must follow rules of community as they are could be punished by DAO in case of fraud or other violations of rules of community.
Definition contain defination of some contracts function, Migrations are help to follow actual contract addresses
Golang artefacts of solidity contracts is used for bindings contract to native golang applications.
You can find golang artefacts in contracts directory
To generate artefact from source you should install abigen first.
Abigen is a tool from go-ethereum package.
First you need to install godep tool by
go get github.com/tools/godep
Then you should install abigen itself
cd $GOPATH/src/github.com/ethereum/go-ethereum
godep go install ./cmd/abigen
If something wrong with abigen dependency (like someone forget to check broken dep from abigen in official go-ethereum)
you could try just go install abigen from ./cmd/ directory.
You should see your abigen binary in /bin/ your $GOPATH directory.
You should use proper way to generate golang bindings from source .sol files.
abigen --sol token.sol --pkg main --out token.go
Where the flags are:
--abi: Mandatory path to the contract ABI to bind to
--pgk: Mandatory Go package name to place the Go code into
--type: Optional Go type name to assign to the binding struct
--out: Optional output path for the generated Go source file (not set = stdout)
this command will generate go bindings from your token.sol contract and you can further use it in your go application.
note, that if you will use --type flags as
abigen --abi token.abi --pkg main --type Token --out token.go
it will create new Token struct for your go project and you can be use this struct without neccesarry to import your generated file into main project.
This is simplier way to develop, but may be confusing when you would not remember where do you declarated this struct and how to change it.
note - you **have to ** store zeppelin library in contracts directory because apigen does not recognise ethpm folders as truffle do.
You can generate go binds from sol files by go generate see more info in generator.go in contracts directory.
To generate packages you need to run in console go generate in contracts directory. Generated files will be saved in /go-build/ directory.
To run rinkey testnet through go-ethereum node you should run it as follows:
geth --networkid=4 --datadir=$HOME/.rinkeby --cache=512 --ethstats='yournode:Respect my authoritah!@stats.rinkeby.io' --bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb4d375b77eab56516d34bfbd3c1a833fc51296ff084b770b94fb9028c4d25ccf@52.169.42.101:30303 --rpc --password <(echo yourpassword) --unlock 0 --rpccorsdomain localhost --rpcport 8080
To attach official ethereum foundation wallet
ethereumwallet --rpc $HOME/.rinkeby/geth.ipc --node-networkid=4 --node-datadir=$HOME/.rinkeby --node-ethstats='yournode:Respect my authoritah!@stats.rinkeby.io' --node-bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb4d375b77eab56516d34bfbd3c1a833fc51296ff084b770b94fb9028c4d25ccf@52.169.42.101:30303
Metamask plugin is currently working perfect with Rinkbey testnet. You could run frontend of Factory as npm run dev which will build react frontend and start minimal npm server
You could interact with Factory contracts throught this frontend and using metamask as a node to work with rinkbey testnet.
