24. Enterprise grade blockchain platform enabling distrusting parties to form and maintain consensus about the existence, status and evolution of a set of shared facts. 24
25. Key Concepts States States are immutable objects that represent shared facts such as a financial agreement or contract at a specific point in time Transactions Transactions consume input states and create output states. Newly created output states replace the input states which are marked as historic Contracts Contracts control the evolution of states by allowing relevant participants to check for transaction validity Flows Flows are light-weight processes used to coordinate interactions required for peers to create and agree transactions
26. What it is What it does Trust Root The single, long-term cryptographic key which all network‘s identity (X509) certificates root back to It provides the basis of trust in the provenance of data, recognised by participants Identity Manager Admits new members onto the network via granting an identity certificate Performs 3 checks on new certificate requests and grants based on passing the checks Network Map A list of IP addresses and legal entity names of each participant on the network, which all participants can access Acts as a Corda Network ‘phone directory’ Notary Node or cluster of notary nodes Prevents double-spend of input states nodes notary A Corda Network The Network Permissioned network with public identities allowing nodes to communicate directly with each other
27. Testing challenges • Platform technology (build CorDapps to test the full API) • Highly distributed (complexity in test automation) • Heterogeneous networks (combinatorial explosion) • Highly secure (cryptography, ledger consistency is everything) • Eventually consistent (transaction flows can be complex) • Evolutionary lifecycle (platform and CorDapp upgrades) • Highly available (resiliency testing) • Temporal (performance testing)
