CryptoCoinWatch is an open source Ethereum datafeed to watch the amount received on any cryptocurrency address. This data can be subsequently used by any other smart contract on the Ethereum blockchain: CFDs, escrows, betting contracts, etc. While using a single datafeed would be a single point of failure, contracts could (should) select multiple independent datafeeds (with different sources) to compensate.
Basically this contract will offer a proxy for
, i.e https://blockchain.info/q/getreceivedbyaddress/36PrZ1KHYMpqSyAQXSG8VwbUiq2EogxLo2
Contract source code, documentation and test code is available on https://github.com/EtherCasts/cryptocoinwatch
I am currently working on the datafeed watchdog process and creating a small DApp UI.
