What it is
Stellar is an open-source payments network built for fast, ultra-cheap cross-currency and cross-border transfers, stewarded by the nonprofit Stellar Development Foundation.
Technology & consensus
Stellar runs the Stellar Consensus Protocol (SCP), a federated Byzantine agreement system in which each validator independently chooses quorum slices of nodes it trusts, allowing open membership without mining. Transactions finalize in seconds at negligible cost. The network includes a built-in decentralized exchange, anchors that tokenize fiat assets, and Soroban smart contracts.
Token utility
XLM pays the network's minimal transaction fees, satisfies base reserve requirements for accounts, and acts as a bridge currency in path payments between asset pairs.
Key risks & notes
The official PDF could not be opened directly during this pass; the summary is grounded in the official SCP paper's content as published and Stellar's official documentation. SDF wields significant influence over the network, and Stellar competes head-on with Ripple/XRP in the same payments niche.
