Why use Noumenon?
Most wallets and exchanges either require KYC or hold your funds in centralized custody. This creates a dilemma — your financial history is either exposed on a public blockchain, or your assets are controlled by a central authority. Noumenon resolves this. With Noumenon, private transactions are visible only to the designated KYC authority — not the public — and you retain full ownership of your funds. The KYC authority serves solely as a data custodian and is legally obligated to protect your information. Your finances should remain your business.
Can someone freeze your funds?
No. The Noumenon blockchain remains open and permissionless — you can transact freely at any time. Privacy is an optional layer, not a requirement. If you choose not to comply with KYC, you simply won't have access to private transactions—but your ability to use the network remains unrestricted. Once your funds are in your account, they belong solely to you. The system ensures your ownership is protected, while giving you the choice to transact privately or transparently, depending on your preferences and compliance status.
Transparency when needed. Privacy when required. Compliance by design.
How we do it?
Confidential Transactions
Noumenon supports fully confidential transactions using RingCT and MLSAG obscuring both the sender's identity and the transaction amount. Each transaction output can be either public or private, thanks to advanced techniques involving Pedersen Commitments — giving users full flexibility over their privacy preferences. For a deeper dive into the cryptography behind this, read our docs.
Transaction's Confidentiality Approver
Noumenon introduces a dual-layer system: traditional miners process transactions, and a KYC authority that enables private transactions. Once verified, your identity stays protected—your data remains private and secure under local data protection laws. Only transactions authorised by these KYC authorities are allowed to be private, ensuring privacy without violating regulatory requirements
Noumenon Token Manager
A highly secure, rigorously audited token manager handles the minting of wrapped tokens on the Noumenon blockchain. All minting operations are tightly regulated and require multi-party signatures, ensuring trust and transparency. It also facilitates fast, compliant settlement of onramps and offramps through the Noumenon Exchange.
Cryptography feels like magic — and Noumenon is living proof.
