Key terms

Lightning Network

A payment channel network built on top of Bitcoin that enables near-instant, very low-cost transactions. As of December 2025, capacity reached a record 5,637 BTC across approximately 14,940 nodes and 48,678 channels.

Stablecoin

A cryptocurrency designed to maintain a stable value, typically pegged 1-to-1 to a fiat currency like the US dollar. Stablecoin payment volumes reached $11.1 trillion in 2025.

Legal tender

A form of money that must be accepted by law for payment of debts. El Salvador adopted Bitcoin as legal tender on September 7, 2021; the mandate was largely rolled back in February 2025 as part of an IMF loan agreement.

Peer-to-peer (P2P)

Direct transactions between individuals without an intermediary like a bank or exchange. P2P trading is particularly significant in countries like Nigeria where formal exchange access is restricted.

Chivo Wallet

The El Salvador government-operated Bitcoin wallet launched in 2021. Adoption rates declined from 25.7% in 2021 to 8.1% in 2024, and the IMF agreement of December 2024 required winding it down.

Micropayment

A very small financial transaction (often a fraction of a cent) that is impractical to process through traditional payment networks due to fees, but can be processed efficiently on Lightning or other low-fee crypto rails.

B2B payments

Business-to-business payments. Roughly 60% of real-world stablecoin payment volume is B2B, including supplier payments, treasury operations, and inter-exchange settlement.

Chainalysis Geography of Crypto Adoption Index

An annual ranking of countries by cryptocurrency adoption based on multiple weighted metrics. The 2024 edition ranked India #1, Nigeria #2, Indonesia #3, the US #4, and Vietnam #5.

Hyperinflation hedge

A use case for stablecoins in countries with rapidly depreciating currencies. In Argentina, 61.8% of crypto activity is in stablecoins (vs 44.7% globally), reflecting their use to preserve purchasing power.

Flexa / Spedn

A payment network that allows merchants to accept cryptocurrency without taking direct exposure. Flexa converts crypto to fiat at the point of sale; Whole Foods historically participated.
