10 May 2017 - SAN MATEO, Calif.--(BUSINESS WIRE)
PokitDok announced today that it has selected the Linux Foundation’s Hyperledger Sawtooth™, as its premier platform for recording DokChain healthcare transactions. Hyperledger Sawtooth is an open source blockchain project contributed by Intel. PokitDok’s announcement represents a step forward in the development of blockchain smart contracts that can manage and resolve patient identities, control access to personal health records, automatically adjudicate healthcare claims, and power a complex supply chain for medical environments.
DokChain is PokitDok’s implementation of blockchain for healthcare. It is the centerpiece of an alliance among health systems, insurers, technology, supply chain companies, and financial institutions. DokChain is designed to record valid transactions that capture the history and process administrative aspects of an individual’s care. PokitDok maintains trading partnerships, connecting with more than 550 health insurers and payers to enable seamless data exchange for identity verification, eligibility checks, claims processing, authorizations, and medical referrals. Data, regardless of where it originates, is maintained and verified across an encrypted, distributed network that utilizes Hyperledger Sawtooth and Intel® Software Guard Extensions (Intel ® SGX).
“Blockchain is fundamental to the next computing cycle and will introduce new dimensions of compute power, speed, and security,” said Ted Tanner, Jr., co-founder and CTO, PokitDok. “In the healthcare sector, protecting patient data is paramount, as is sharply reducing blatant inefficiency, which is why we chose to work with Intel to do business on the blockchain.”

Intel SGX is an Intel technology for application developers like PokitDok, seeking to protect select code and data from disclosure or modification. Intel SGX makes such protections possible through the use of “enclaves” which are protected areas of execution. Within these protected enclaves, Hyperledger Sawtooth’s unique consensus mechanism, “Proof of Elapsed Time”, uses Intel SGX for an economical leader election process. Hyperledger Sawtooth also offers customizable transaction families, which enable PokitDok to create blockchain solutions tailored to the needs of the healthcare industry.
“Intel SGX can help improve blockchain scalability, security, and privacy,” said Jerry Bautista, vice president New Technology Group and general manager of Intel’s New Business Group. “With Hyperledger Sawtooth, PokitDok can utilize Intel SGX and other hardware platform capabilities to enhance and increase protection of their healthcare system.”
PokitDok technology solutions, business processes, engineering methodologies, and delivery protocols are designed and executed for security and compliance. PokitDok is HIPAA and PCI compliant, was awarded a Phase IV CAQH® Committee on Operating Rules for Information Exchange (CORE®) Certification Seal, and is accredited by the Electronic Healthcare Network Accreditation Commission (EHNAC).
