@noblocknoparty/blockparty-contracts v0.9.0

Hacking guide

If you are interested in contributing to blockparty, have a look into "help wanted" tag on Github issues. They are relatively easy and does not require so much application specific knowledges.

Prerequisite

• geth
• nodejs
• npm
• webpack
• ganache-cli = v6.0.3 (ganache-core: 2.0.2) for local use

Installation

• Run npm

Running test

• Run ganache-cli -a 300 in one console
• Generate test public/secret key

cd tmp/
openssl genrsa 2048 > test_private.key
openssl rsa -pubout < test_private.key > test_public.key

• Run npm run test

Running test coverage

./node_modules/.bin/solidity-coverage

Running locally

• Run local node (geth, ganache test rpc, etc)
• Run ./node_modules/.bin/truffle migrate --network development
• Run npm run dev
• Open http://localhost:8080

NOTE: If you have metamask, your account on ganache will not have ether to register. Either send it via terminal, or open the browser in the incognite mode, so you use default account on local node.

Building asset files to deploy

• Run npm run build
• Upload the content of files under build directory

Encryption (experimental)

By passing public key file location to parameter of Conference during migration, it can allow user to register with their user name encrypted.

Configurable values (experimental)

Event name is configurable as name

eg: Encrypt participant name

./node_modules/.bin/truffle migrate --config '{"name":"CodeUp No..", "encryption":"./tmp/test_public.key"  }'

Changing number of participants

./node_modules/.bin/truffle migrate --config '{"name":"CodeUp No..", "limitOfParticipants":15}'

Deploying and running on real network

For ropsten and mainnet it now deploys via Infura. Pass the extra to set deployment specific

--network $NETWORK --mnemonic $SECRET

NOTE: ropsten and mainnet uses different gasPrice. Check truffle.js file and scripts/util/set_gas.js for the detail.
