Your own full node
Every COIN Wallet runs a full node. It keeps its own copy of the blockchain and checks every block itself, so you never have to trust anyone else's server.
Automatic. The wallet starts its node when it opens and connects to the Coin network by itself. There's nothing to install or configure.
- DownloadsFetches new blocks and transactions from other nodes.
- ChecksTests every block and every transaction against Coin's rules, and throws out anything that breaks them.
- RelaysPasses valid transactions and blocks on to its peers.
- Answers your walletYour wallet asks your own node about the blockchain, not a stranger's server.
Why it matters
- Nobody can fool your wallet. Your node checks everything itself, so no server can show you a fake balance or a payment that never happened.
- Nobody watches you use it. A remote node sees your IP address and the payments you send through it. Your own node doesn't tell anyone anything.
- The network gets stronger. Every node is another copy of the blockchain that nobody can switch off.
The first sync
The first time it starts, your node downloads every block since the genesis block on 20 October 2026 and checks each one. The wallet shows its progress and says Connected once it has caught up. After that, it only needs the new blocks.
Saving disk space
The blockchain grows over time. To keep a smaller copy, turn on Prune blockchain when you set the wallet up. A pruned node still checks every block. It just keeps less of the old data on disk.
Going further
To help the network more, keep a node online around the clock: see Run a node. If a computer can't run a node, the wallet can use someone else's instead: see Remote nodes.
