What is Stellar Lumens (XLM)?
Stellar is much faster, cheaper, and more energy-efficient than typical blockchain-based systems.
Anyone is able to participate and no central authority dictates whose approval is required for consensus.
In practice, nodes can reach consensus at timescales humans expect for web or payment transactions—i.e., a few seconds at most.
Users have the freedom to trust any combination of parties they see fit. For example, a small non-profit may play a key role in keeping much larger institutions honest.
Safety rests on digital signatures and hash families whose parameters can realistically be tuned to protect against adversaries with unimaginably vast computing power.
