Enterprise-Grade Blockchain
EXPI runs on a next-generation Layer 0 blockchain targeting 600,000+ TPS, with instant finality, post-quantum security, and continuous biometric owner verification — infrastructure built for a billion users.

Delegated Proof-of-Power Consensus
Our chain uses a modified Tendermint BFT consensus protocol with one critical difference: every active validator has an equal chance of proposing the next block — regardless of stake size. This eliminates the plutocratic tendencies of traditional Proof-of-Stake systems.
Block rewards are split 50/50 — half to the proposer, half shared equally among all active validators — creating a truly fair and decentralised incentive structure.
Real Assets, Not Reward Points
Every ride, flight, payment, and step you take generates EXPR — tradeable digital assets on our blockchain. Unlike traditional loyalty points, EXPR tokens are yours: liquid, transferable, and backed by real platform utility.

Off-Chain Execution, On-Chain Security
Our execution-decoupled architecture separates application logic from consensus. Smart contract equivalent applications run off-chain via our Verifiable Immutable Application layer — the base chain handles only ordering and security, eliminating the throughput bottleneck that plagues traditional smart contract platforms.
This means unlimited parallel application scaling without any one app congesting the network — exactly what a billion-user platform requires.
Chain Infrastructure
Built from first principles for global scale — not adapted from legacy systems.
600,000+ TPS Target
Our Layer 0 infrastructure is engineered to reach a target of over 600,000 transactions per second on commodity hardware — far exceeding any legacy blockchain and most traditional payment networks.
Instant Finality
Transactions are irreversibly finalised in seconds. No waiting for confirmations. No risk of chain reorganisation. Once included, it's done.
Delegated Proof-of-Power
Our consensus mechanism gives all active validators equal selection probability — not weighted by stake — ensuring true decentralisation and fair block rewards.
Post-Quantum Security
We use Falcon — a NIST-standardised post-quantum signature scheme — for all validator votes and block proposals. Future-proofed against quantum computing threats.
Execution-Decoupled Architecture
Smart contract logic runs off-chain via our Verifiable Immutable Application layer, freeing the chain to focus purely on ordering and securing transactions at maximum speed.
Horizontal Scaling
Applications scale independently without congesting the base chain. Add capacity by adding cores — throughput grows linearly with hardware investment.
Continuous Owner Verification
Standard Face ID secures your phone — not your assets. Powered by Haven — the biometric engine we acquired — EXPI's Continuous Facial Recognition (CFR) verifies you are the owner during every transaction, every second, invisibly in the background.
Continuous Biometric Verification
Your face authorises every action — not just login. Our continuous recognition engine runs invisibly multiple times per second. The moment it detects it isn't you, execution stops — not paused, stopped.
On-Device Biometric Storage
Your biometric data is encrypted and stored only on your device. It is never transmitted, never stored on our servers, and never shared. Our system outputs a boolean signal only — true or false — no identity data leaves your phone.
Stolen Device Protection
Stolen keys don't work. Every transaction requires a live biometric match at the moment of signing. Hand your unlocked phone to someone else — transactional access stops instantly.
Anti-Spoofing Liveness Detection
Advanced liveness detection is hardened against deepfakes, AI-generated faces, GAN spoofs, 2D photos, 3D masks, and video replay attacks — state-of-the-art resistance to all known spoofing vectors.
Security Circle & Dual Signatory
Set your own approval thresholds. Large transfers require biometric confirmation from a nominated Security Circle member — giving you institutional-grade multi-signatory controls in a consumer-friendly interface.
Seedless & Passwordless Recovery
No seed phrases. No passwords. No single points of failure. Recovery uses your trusted contacts as a biometric-verified social layer — eliminating the most common cause of permanent asset loss.
Zero-Knowledge by Architecture
Our biometric layer outputs a single boolean signal — TRUE or FALSE. No biometric data ever leaves your device. No identity is stored on our servers. The verification result is cryptographically anchored to each transaction without exposing any personal information — even to us.
Security Across Money and Movement
Haven's Continuous Facial Recognition doesn't stop at your wallet. The same engine authorises every mobility booking — your face signs each ride, flight, and charter, and a stolen phone or password books nothing. Zero-credential by design, engineered to block deepfake and spoof attacks. EXPI is the first platform where getting there is as secure as getting paid.
Security & Compliance Standards
Every layer of the EXPI stack is built to institutional-grade security standards.
EXPR Token
Utility. Rewards. Governance.
EXPR is the native token of the EXPI ecosystem — earned through everyday activity and redeemable across the platform. It powers Move-to-Earn rewards, staking yield, governance participation, and fee discounts on mobility bookings. Not speculative — functional.
