What is Stellar (XLM)?
Stellar (XLM) — or Stellar Lumens — is the native cryptocurrency of the Stellar payment protocol. The payment protocol was launched in 2014, along with the Lumens cryptocurrency designed to support digital transactions across the network.
While XLM is the main denomination of the cryptocurrency, there are smaller denominations too. A Stroop is the smallest unit that will register on the Stellar blockchain and is worth 0.000001 XLM. Stroops are used to add precision to payments and transactions and handle network and transaction fees.
XLM is based on a blockchain, but no mining process is involved in transactions and validations. Instead, the Stellar network adopts a different type of consensus logic across its 66 validator nodes, plus the three nodes operated by Stellar itself.
