The Decentralized Autonomous Investment Organization (DAIO)

Objective

Coordinate a simple investment decision—buy something or not— among all participants with a predetermined redistribution timeframe

Setup

Geth, Ethereum Wallet, Mist (OSX)

  1. Download and install either Ethereum Wallet or Mist from the official repo. Geth will be installed as well.

  2. (Optional) Sync the mainnet chain (use --fast or light client)

Testnet Blockchain (OSX)

For a more thorough step-by-step guide, see HowTo: Set up an Ethereum private local testnet

  1. Create a new dir to store testnet blockchain files: mkdir ~/testnet

  2. Define genesis block configs in a new json file genesis.json:

{
    "config": {
        "chainId": 15,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
    "nonce": "0x0000000000000042",
    "timestamp": "0x0",
    "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "gasLimit": "0x8000000",
    "difficulty": "0x400",
    "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "coinbase": "0x3333333333333333333333333333333333333333",
    "alloc": {}
}

  1. Initialize testnet blockchain: geth --datadir "~/testnet" --identity "Private" --networkid 15 --nodiscover --maxpeers 0 init genesis.json

  2. Create an address and start mining:

geth --datadir "~/testnet" --identity "Private" --networkid 15 --nodiscover --maxpeers 0 console

personal.newAccount("password")

miner.setEtherbase(personal.listAccounts[0])

miner.start()

Deploy Contract

  1. Make sure testnet blockchain is active and mining (see Testnet Blockchain (OSX)

  2. Launch Ethereum Wallet or Mist on testnet: /Applications/Ethereum\ Wallet.app/Contents/MacOS/Ethereum\ Wallet --rpc ~/testnet/geth.ipc

  3. Contracts -> Deploy New Contract

  4. Copy&paste code in daio.sol into Solidity Contract Source Code, choose From account and Ether amount to send (this initial amount will be considered as the fundShare)

  5. Deploy
