API Reference. Each NEO-CLI node provides an API interface for obtaining blockchain data from it, making it easy to develop blockchain applications. The interface is provided via JSON-RPC, and the underlying protocol uses HTTP/HTTPS for communication. To start a node that provides an RPC service, you must install the plugin RpcServer If they call the API even an instant later, the API could have changed — been depreciated, hacked, or for a number of other reasons — and all the nodes would get a different result. This means none of the nodes would be able to agree upon what the actual state of the blockchain is

Blockchain as a Service. Topl's Blockchain-as-a-Service (BaaS) offerings are uniquely suited to solve many of the problems with current supply chain management and certification methods. With BaaS, we empower organizations to drastically cut certification costs and produce unprecedented trust and transparency around ESG initiatives The Data API also allows for getting the contents of any block, getting a particular transaction in a block, and fetching the balance of any account present in a block. Rosetta validation tooling ensures that the balance computed for any account from operations in blocks is equal to the balance returned by the node (often called reconciliation) Build Blockchain. We are ready to start building our blockchain. Our blockchain is created using an empty constructor. This constructor sets some important parameters like our genesis block, the mining difficulty, any pending transactions and the mining reward for mining a new block.We will explain the exact use of the mining difficulty later in this article This creates one or more watch-only addresses, whose activity and balance can be retrieved via various APIs (e.g. with the includeWatchOnly parameter), but whose funds cannot be spent by this node. The rescan parameter controls whether and how the blockchain is rescanned for transactions relating to all wallet addresses, including these new ones
