A blockchain is a decentralized database where information is stored in a chain of blocks. Interacting with this structure requires a special interface, which is ton rpc. It is a communication protocol that allows external applications to communicate with TON network nodes. Developers use ton rpc to send requests to the blockchain: retrieve transaction data, check wallet balances, execute smart contracts, and monitor the network's status. Without this protocol, applications would be unable to read information from the blockchain or initiate new transactions. Thus, ton rpc serves as a critical link between the frontend (wallets, dApps) and the blockchain backend (TON nodes). It is a technological bridge that transforms a static database into an interactive, decentralized ecosystem.
