OYB Blockchain API

OYB blockchain API advanced security and, in particular, how each new transaction in the API is followed by “proof” of Chainpoint which guarantees the authenticity of data related to the transaction’s time of creation and other relevant information. Chainpoint attaches the data’s hash to blockchain units so that anyone with access to the “proof” is able to verify the data’s authenticity.
