Explore blockchain in healthcare through a course overview, detailing what blockchain is, how it works with cryptography, consensus mechanisms, and smart contracts, and why trust matters in healthcare.
Explore how blockchain builds trust through distributed ledgers and immutable audit trails, using the Yap stones and bitcoin as analogies for secure health care data access.
Cryptographic hashing converts data into fixed-size, one-way hashes (SHA-256, Keccak-256) to secure blockchain, enabling an immutable audit trail through linked blocks and advising against storing large patient data on chain.
Explore public key cryptography and digital signatures in blockchain, detailing how public and private keys enable encryption, authentication, and secure Ethereum accounts.
Explore how consensus mechanisms maintain universal agreement across blockchain nodes, prevent double spending and Sybil attacks, and achieve Byzantine fault tolerance in healthcare data.
Explore the three main blockchain consensus protocols—proof of work, proof of stake, and proof of authority—and their trade-offs in energy use, security, and centralization.
Explore how Ethereum enables secure peer-to-peer code processing and smart contracts with Solidity, using dapps for healthcare and testing in a virtual machine sandbox.
Explore how smart contracts on blockchain automate conditional health care payments, using digital signatures and consensus to ensure timely, temperature-controlled medication delivery and automatic refunds.
Navigate healthcare's complexity and learn how blockchain can drive innovation by starting with a business model, distinguishing data ownership from access, and enabling HIPAA and GDPR-compliant security.
Discover how blockchain acts as a ledger and enables smart contracts to streamline prescriptions, billing, and readmissions, while aligning incentives to support the healthcare commons.
Explore the differences between public and private blockchains and an immutable distributed ledger. Identify when to use public versus private blockchains in health care and related use cases.
Explore the current blockchain landscape in health care, adoption challenges, and the trade-offs between public and private blockchains, including scalability, security risks, and smart contract implications.
Explore consumer-focused scalability for blockchain in health care by comparing proof of work with energy-efficient alternatives like proof of stake and burn, and examining sidechains, off-chain solutions, and sharding.
Explore secure decentralized data storage for blockchain. Understand why on-chain storage is costly and insecure, and how key pair systems, distributed hash tables, and data sharding enable affordable, scalable storage.
Blockchain technology has the potential to transform the healthcare industry. People in the healthcare sector, however, need comprehensive tools to guide them through a functional and technical understanding of blockchain. This course will give an overview of what blockchain is, how it works, and how it is impacting the healthcare industry, so professionals can be empowered as the field continues to evolve.
