Category: NFTs with censorship resistance Website: stargaze.zone

About Stargaze

Stargaze is a fully on-chain NFT platform built on Cosmos that gives creators a censorship-resistant space to mint, sell, and preserve digital art and assets. It avoids reliance on IPFS or third-party storage by storing all NFT metadata directly on-chain. The platform also offers community-driven governance and launchpad features.

Key Stargaze features

• Fully on-chain NFT minting
• Creator-first launchpad
• Community-led governance

Category: Confidential computing Website: arcium.com

About Arcium

Arcium enables private, off-chain computation for smart contracts using secure enclaves. It is ideal for situations where data confidentiality and scalability are critical. It combines decentralized compute infrastructure with strong cryptographic guarantees. Arcium is helping bring privacy to areas like machine learning, healthcare, and real-time prediction markets.

Key Arcium features

• Enclave-based compute privacy
• Off-chain smart contract execution
• Ideal for ML and data-sensitive dApps

While dApps are decentralized, metadata such as IP addresses, wallet IDs, and action timestamps remain visible unless routed through privacy layers like mixnets.

By routing dApp traffic (such as transaction signing or governance interaction) through Nym’s mixnet via SDK integrations, communication becomes unlinkable and anonymized.

DeFi protocols, DAO voting systems, privacy messaging dApps, and smart contract interfaces where revealing usage or wallet metadata could expose identity or behavior.

Privacy layers may introduce latency or added complexity. Nym aims to mitigate that with SDKs, performant routing modes, and default UX flows that integrate anonymity seamlessly.

Yes—by funneling signature broadcasts through the mixnet, Nym can decouple wallet-level transactions from IP origin, enhancing privacy even in transparent blockchain contexts.
