Company Introduction

SSOT HealthCare Blockchain is a trusted peer-to-peer network maintaining distributed ledger. SSOT Blockchain As A Service (HBASS) is a network consisting of validating nodes (peers) that update the ledger and respond to queries by executing smart contract code-the business logic that runs on the blockchain. External applications invoke transactions or run queries through client SDKs or REST API calls which prompts selected peers to run the smart contracts. Transaction are compliant to HL7, HIPAA & HITECH requirements and standards. Multiple peers endorse (digitally sign) the results, which are then verified and sent to the ordering service. After consensus is reached on the transaction order, transaction results are grouped into cryptographically secured, tamper-proof data blocks and sent to peer nodes to be validated and appended to the ledger. Service administrators can use the SSOT BHaaS Console to configure the blockchain and monitor its operation.
