What is
Light Clients?
Wallet software that verifies blockchain state without downloading the full chain, enabled by NiPoPoWs on Ergo.
Light clients are wallet applications that can verify blockchain state without downloading and storing the entire blockchain. Ergo's NiPoPoWs enable truly trustless light clients - they can cryptographically verify the chain's work using ~1MB proofs instead of trusting a server or downloading gigabytes of data.
Key Points
- Verify without full blockchain
- NiPoPoWs enable ~1MB proofs
- Trustless (no server trust needed)
- Perfect for mobile devices
- Better than SPV (Bitcoin's model)
- Maintains decentralization
Use Cases
1
Mobile wallet verification
2
IoT device integration
3
Browser-based wallets
4
Resource-constrained environments
Technical Details
Traditional SPV clients trust that the longest chain is valid. NiPoPoW light clients can verify the chain's cumulative work cryptographically using superblock sampling. Proofs are ~1MB regardless of chain length, enabling truly trustless mobile wallets.

Common questions about this topic
What can I do with Ergo?
Ergo supports a full ecosystem: trade on Spectrum DEX, use SigmaUSD stablecoin, mix transactions with ErgoMixer, collect NFTs on SkyHarbor, mine with GPUs, lend/borrow on DuckPools, bridge to other chains via Rosen, and build dApps with ErgoScript. It's a complete platform for decentralized finance and applications.

Getting Started
What are NiPoPoWs and why do they matter?
NiPoPoWs (Non-Interactive Proofs of Proof-of-Work) are cryptographic proofs that compress blockchain history. Instead of downloading gigabytes of blocks, light clients can verify the chain with just kilobytes of data. This enables true trustless light wallets, efficient cross-chain bridges, and sidechains - all without trusting third parties.

Technology
Is Ergo a good investment?
This is not financial advice. Ergo has strong fundamentals: fair launch (no VC dump risk), innovative technology (eUTXO, Sigma Protocols, NiPoPoWs), active development, and a cypherpunk ethos. It's a smaller market cap project with higher risk/reward than established chains. Research thoroughly, understand the technology, and never invest more than you can afford to lose.

Why is Ergo sustainable long-term?
Ergo is designed for 100+ year sustainability through three pillars: Autolykos mining (fair, ASIC-resistant), NiPoPoWs (efficient light clients), and storage rent (prevents bloat, funds miners). Unlike chains that depend on infinite growth, Ergo's economics work even with stable or declining usage.
