a blochain-based lottery app

require node, geth, truffle

geth .\geth.exe -datadir <data> -networkid 5777 -rpc -rpcaddr '127.0.0.1' -rpccorsdomain "*" --port 9545 --rpcport 9545 --rpcapi="db,eth,net,web3,personal,web3" console 2> log.log

npm run dev

may need turn off chrome cors security, such as:

.\chrome.lnk --disable-web-security --user-data-dir=D:/blockchain

• Because the app uses cdn js & css & fonts, so please ensure you can access: cloudflare, jsdelivr, googleapis.
• When you buy or sponsor or award a lottery, don't forget to mine in geth.
• Please don't refresh or close tab directly when you're logining in, logout first.
• Be patient and tolerant, thx 😁.
