What you can you do with the DNS DAapp

• Reserve a name with as low as 0.1 ether

• Bid on a name
• Find the current owner's address
• Withdraw your bid - if you are outbidden
• As a owner accept bids and transfer name ownership
• Send money using names

Tech details

• Project is developed using Angular 4.
• Integrated with HD wallet - metamask for signing transactions to the network
• Metamask is the web3 provider.
• I have used a private geth node running at http://localhost:8545/
• Project uses truffle for compiling deploying contracts and uses promisified truffle api for interaction with contracts
• solidity and js tests are in test folder

Build Steps

From the root folder - contract

• Download the source
• npm install
• truffle compile
• truffle migrate --network <network_name>
• truffle test [Optional step]
• ng build --prod
• ng serve

• Note of truffle migrate Since this step deploys the contract to the blockchain. If you are using a private or actual Ethereum blockchain, please make sure that the account you have used in truffle.js is unlocked. I have used my coinbase in truffle.js, so here goes the command.

web3.personal.unlockAccount(eth.coinbase)

Metamask is a dependency for the project

In order to run geth with metamask, please use the flag --rpccorsdomain="chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn

geth --identity "nodeA" --rpccorsdomain "*" --datadir=".\geth_data" -verbosity 6 --port 54259  --rpc --rpcapi "eth,net,web3" --rpcaddr "127.0.0.1" --rpcport 8545 --fast --networkid 15 --nodiscover --mine --minerthreads 1 --rpccorsdomain="chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn
