by Pedro Costa. This is a simple oracle company that may query off-chain APIs upon ask for by other clever contracts and keep the asked for information on the blockchain:
Several developers see intelligent contracts as code running at certain addresses around the blockchain. Having said that, a more basic see of sensible contracts is that they are self-executing software systems able to enforcing agreements between get-togethers at the time precise circumstances are satisfied - as a result the phrase “clever contracts.”
Alternative dependencies: Along with the open-ssl library referenced in the write-up that @tayvano observed, other libraries which might be accustomed to estimate elliptic curve community addresses contain the ecdsa Python library, and Bitcoin's secp256k1 library composed in C although the latter will include tools for formatting bitcoin addresses which are completely various than ethereum addresses because of the formatting actions and different hash algorithms and encoding solutions, although the fundamental private essential and community important are the same, for instance.
