Stellar xlm

Stellar is an open, public blockchain and payment network designed to move digital representations of currencies and other assets quickly and affordably across borders. The network supports both its native lumen (XLM) and issued assets, such as fiat-backed tokens, so users and businesses can exchange value without every participant needing a direct account at the same bank or payment provider. Stellar is maintained by a distributed set of nodes, while the nonprofit Stellar Development Foundation (SDF) supports development and promotes the network; SDF is not the protocol's central operator.

Stellar's main focus is practical financial infrastructure: remittances, account-to-account transfers, payroll, supplier invoices, merchant settlement, aid and social payouts, and on/off-ramps that connect digital assets to local currencies. XLM is the network's native currency. It pays transaction fees, funds account minimum balances (base reserves), and can be used as a bridge or payment asset, but Stellar does not require every payment to be denominated in XLM.

The network reaches agreement with the Stellar Consensus Protocol (SCP), a Federated Byzantine Agreement construction. Rather than mining or weighting votes by staked capital, each validator configures the nodes it trusts and reaches agreement through overlapping quorum slices. This design targets fast settlement and low operating costs, while its safety-first behavior can stop progress when quorum agreement is unavailable.

Traditional cross-border payments often involve several intermediaries, prefunded accounts, limited operating hours, opaque foreign-exchange steps, and fees that are especially burdensome for remittances and smaller businesses. A recipient may also need access to a local cash or banking network before digital value is useful. Stellar addresses this coordination problem with a shared, always-on ledger where assets can settle in seconds, then connects that ledger to regulated anchors, wallets, exchanges, and cash-to-crypto on/off-ramps.

This can make remittances, payroll, treasury transfers, invoices, aid, and merchant payouts faster and less dependent on correspondent-banking rails. Stellar's issued-asset model also lets a payment represent a local currency or dollar token, avoiding the need for the sender and receiver to take long-term XLM price exposure. The network's path payments and decentralized exchange can find conversion paths among assets when liquidity exists.

Stellar also targets financial inclusion: internet-connected users can receive funds in wallets and reach local payout channels, while organizations can distribute aid or social payments with transparent, portable records. These are capabilities, not guarantees. Access still depends on internet connectivity, a usable wallet, local anchors, liquidity, identity/compliance requirements, and the laws and institutions in each country; blockchain alone does not eliminate poverty, currency risk, fraud, or the need for trusted off-ramps.

A Stellar account signs a transaction with its private key and submits it to the peer-to-peer network. Validators check the transaction against protocol rules and propose transaction sets for the next ledger. Stellar's SCP has two broad phases: nomination, in which candidate transaction sets are selected, and ballot, in which nodes prepare and commit one candidate. Federated voting moves statements through vote, accept, and confirm states. Once a node's quorum slice confirms a statement, it can safely apply the ledger; finalized ledgers contain the agreed transactions.

Each validator chooses a quorum set: trusted validators plus a threshold. A quorum slice is a threshold-satisfying subset of that set; a quorum is a set of nodes in which every node has a quorum slice. Safety depends on sufficient overlap among honest nodes' quorum slices, while liveness can suffer if trusted nodes are offline or quorum configuration is poorly connected. SCP prioritizes safety and fault tolerance over liveness, so the network may stop rather than finalize conflicting histories when agreement is not possible. Validators receive no protocol mining or staking reward; organizations run them for network security and resiliency.

Stellar's ledger supports native XLM and issued assets identified by an issuer account. Trustlines let accounts authorize holding an issued asset. Anchors provide the bridge between Stellar assets and traditional financial systems, handling their own onboarding, KYC/AML, sanctions screening, and payout obligations. The network's built-in exchange and path-payment features can exchange assets through available offers and liquidity. XLM is required for transaction fees and account reserves; current developer documentation states a base reserve of 0.5 XLM and a minimum account balance of two base reserves, though protocol parameters can change.

Unlike mined cryptocurrencies, all original XLM was created when the network launched. Stellar's developer documentation says 100 billion XLM were created initially, early annual inflation ended by validator vote on October 28, 2019, and inaccessible balances sent to accounts with no signers are counted as burned. Supply categories and balances change, so live supply figures should be checked in SDF's dashboard rather than treated as permanent facts.
