node, which implements a Witnet full node with an internal single-account, single-address wallet and a JSON-RPC API over TCP.wallet, which implements a BIP-32 compliant, multi-account, multi-address Hierarchical Deterministic wallet, and a JSON-RPC API over WebSockets.node componentnode component is standalone — you can run it on its own and it will provide full-node functionality: syncing up the Witnet block chain, validate transactions and blocks in real time, and (optionally) propose blocks.node instance is fully synced, its JSON-RPC over TCP API offers a minimal single-account, single-address wallet.21338 can easily be achieved with this Docker one-liner:wallet componentwallet component is NOT standalone. It requires a connection to an instance of the node component that will act as its "backend":node instance that acts as the backend for the wallet component contained within the Sheikah Witnet wallet desktop app, which follows exactly the same architecture:node component, because otherwise they may be disclosing their addresses and balances to 3rd parties, as the queries between the wallet and node components need to be sent over the Internet.wallet component is different than the one from the node not because it has much more advanced wallet functionality, and uses a WebSockets transport instead of plain TCP (this is to enable web wallets and similar apps).
