Naivechain
Naivechain is an educational blockchain implementation designed to demonstrate the fundamentals of distributed ledgers. It functions as a proof-of-work blockchain where nodes solve computational puzzles to validate new blocks and secure the network.
The system operates as a peer-to-peer network using WebSockets to propagate transactions and synchronize state across nodes. It includes an asymmetric key wallet for generating public and private key pairs, enabling users to sign transactions and manage digital identities.
Node administration and ledger data retrieval are handled through an HTTP blockchain interface. The project covers core distributed system capabilities including cryptographic hash chaining, peer-to-peer networking, and distributed state synchronization.
