The floor everything else is built on.
Core is the open-source, public blockchain under the whole stack — live since 2022, secured by its own Ed448 cryptography and PoDE (Proof of Distributed Efficiency), an energy-efficient consensus built to run green. No company owns it; every layer above settles back down here.
Luna is a decentralized mesh network — it carries transactions and messages over radio or plain SMS, with no connection at all. Designed so there is no single carrier in the middle and far fewer points that can be switched off.
CorePass is your digital identity: verified once, kept encrypted on your device, shared only when you approve. Since October 2026 companies verify too, with a self-custody wallet run on the team’s own approval rules. Any app can plug in through the CorePass Connector.
PayTo builds on an open payment standard (RFC 8905), settling straight on Core. It is live for payments in XCB and CTN; on- and off-ramps between bank and wallet are not live yet. Fees and conversion costs depend on the route and are shown before you pay.
The stack as everyday apps. Ping Exchange is a hybrid exchange, supervised under Swiss anti-money-laundering rules (SO-FIT), for crypto and stable tokens, with commodity and stock markets rolling out — the bridge between TradFi and decentralization.
