About Crypto

Short Demo based on real Ad-Exchange workflow shows capability to create micro-payment operations. There are several participants:

• Publisher -
• Ad-Server -
• Two DSPs -
• Monitoring -

The current version of code has been tested with Kovan testnet only for now. However, other testnet should also work after proper configurations.

Prerequisites and Notes

Parity installation

• More information about parity intallation can be found https://www.parity.io/. The version of parity being used is 1.8.4-beta.
• Run your parity service with the following command:

parity --geth --chain kovan --force-ui --reseal-min-period 0 --jsonrpc-cors "*" --jsonrpc-apis web3,eth,net,parity,traces,rpc,personal

It may take a while to get syncronized.
