Node

Definition

A node is a computer participating in a blockchain network, storing blockchain data and validating transactions. Nodes enforce consensus rules and propagate information. Post-quantum nodes must support larger signature verification and updated cryptographic libraries.

Technical Explanation

Node types include: full nodes (complete blockchain copy, full validation), light nodes (headers only, SPV verification), archive nodes (full historical state), and validator nodes (participate in consensus). Each type trades resources for trust minimization.

Post-quantum nodes require: updated cryptographic libraries (Kyber, SPHINCS+), more bandwidth (larger signatures), adequate storage (larger transactions), and CPU for verifying quantum-resistant signatures. Optimization ensures practical node operation.

SynX Relevance

SynX nodes verify SPHINCS+ transaction signatures and Kyber-768 key encapsulations. Optimized verification algorithms ensure nodes run on standard hardware. More nodes increase network decentralization and security—run a SynX node to strengthen the network.

Frequently Asked Questions

What hardware do I need to run a node?: Modern PC with adequate storage (SSD recommended), stable internet. No specialized hardware required.
Do nodes need more resources for post-quantum?: Slightly more—larger signatures mean more bandwidth and verification time, but optimizations keep requirements practical.
Should I run a full node or light node?: Full nodes provide maximum security and help the network. Light nodes work for personal use with less resources.
