Table objects provide access to the collection of entities stored in a specific table. They are stored in src/Model/Table. The file we’ll be creating Features Collection CollectionTrait now uses the newCollection method to create clones. This allows sub-classes to have collection methods create instances of themselves instead of using Collection. Console

modify assets using chaincode transactions. Assets are represented in Hyperledger Fabric as a collection of key-value pairs, with state changes recorded as transactions on a Channel ledger. Assets can organizations on that channel need to keep their transaction data confidential, a private data collection (collection) is used to segregate this data in a private database, logically separate from the channel these concepts in a little more detail. What are PKIs? A public key infrastructure (PKI) is a collection of internet technologies that provides secure communications in a network. It’s PKI that puts the
