Nodes
The TON Blockchain is maintained by a distributed network of nodes.
Some are validators, who produce and validate blocks. Others are full nodes, who keep history and serve data.
Together, these components form the backbone of TON’s decentralized architecture.
What do nodes actually keep
Nodes maintain:
- Blocks — ordered chains of transactions.
- Shard states — the current state of accounts (balances, code, and data).
- Proofs — cryptographic guarantees that connect states and blocks.
This ensures that even a lite client can verify the correctness of an account’s state without trusting any single node — relying only on cryptographic proofs.
