Symbol-based networks rely on nodes to provide a trustless, high-performance, and secure blockchain platform.

These nodes are deployed using catapult-server software, a C++ rewrite of the previous Java-written NEM distributed ledger that has been running since 2015.

Learn more about the protocol by reading the Whitepaper and this documentation.
