CyberShard Calendar

CyberShard utilises client-side cryptography to partition your private key into independent shards directly on your device. By processing the split locally, we ensure your full private key is never exposed to the internet or our servers, eliminating the risk of a central breach.

If a single share (or any number below the threshold) is stolen, your private key remains mathematically secure. The stolen fragments are useless on their own. You would simply need to use your remaining Shards to move your funds to a new secure setup.

To enhance security, CyberShard uses verifiable secret sharing using Pedersen commitments, enabling each shard to be validated for integrity without revealing the underlying key. This prevents tampering or maliciously generated shards during the distribution phase.

You can implement it via CyberShard Simple plan or through Premium plan. CyberShard facilitates this process by ensuring your security is defined by mathematics rather than a single proprietary product.

If you lose more recovery Shards than the threshold requires, you will be unable to reconstruct your private key, meaning access to your assets is permanently lost. This is why CyberShard recommends distributing Shards across diverse, secure locations.

Absolutely. You can opt for the Premium Plan and apply a password to a wallet secured via Shamir Secret Sharing. This provides an additional layer of protection, ensuring that even if the required threshold of Shards is compromised, your funds remain inaccessible without the Master password.

Absolutely not. Your Seed phrase is encrypted and fragmented locally on your computer. We employ a 'Zero-Trace' protocol: once the shards are created, your RAM is flushed and the session is refreshed to wipe all temporary data. By integrating Pedersen Commitments, we ensure that even if a shard were intercepted, it would be impossible for an attacker to verify or rebuild your private key. Without the required number of shards, the data is mathematically invisible

When your Seed phrase is fragmented, CyberShard generates a Pedersen Commitment for each shard. This cryptographic technique allows the system to verify that a fragment is authentic and unaltered without ever "seeing" the actual data. This creates a Verifiable Secret Sharing (VSS) environment where you can mathematically prove a shard is correct during recovery, while the storage providers remain "blind" to your private key.

CyberShard secures your wealth in three stages: Encrypt, Verify, and Restore. Your hardware’s Secure Element fragments your seed into encrypted shards, which are processed locally on your computer for maximum security isolation. These shards are then distributed among three independent professional custodians. By decentralizing your storage, we ensure that no single company—not even us, can ever access your assets.

To unlock your "vault", you must provide three inseparable elements: your Encrypted Shards, your Vault name, and your Password. If a single element is missing or incorrect, the mathematical door remains sealed. You don't just "claim" to be the owner; you demonstrate it through elements that only you possess and can unlock.

A Pedersen Commitment is a cryptographic algorithm that allows a prover to commit to a certain value without revealing it, while remaining unable to change that value later. In the CyberShard ecosystem, this ensures that the fragments held by providers are mathematically "locked" and cannot be tampered with or altered without detection.

We maintain a standing adversarial bounty program where a genuine Seed Phrase is exposed to the global hacking community. This serves as a continuous, 'in-the-wild' stress test of our system. Our confidence is backed by the fact that, despite the incentive, the underlying mathematics of our distributed shards remain uncompromised.

This is where Pedersen surpasses traditional Shamir (SSS). When you reconstruct your secret, you provide your Commitments (public mathematical proofs). The server then runs a verification equation: $$g^y h^{y'} \equiv \prod C_i^{x^i} \pmod p$$ This proves that the shards have not been modified and belong exactly to the original set you generated.

Possession alone is insufficient. All Shards are protected by AES-256-GCM encryption. Recovery requests undergo verification based on commitments, password, vault name otherwise the secret remains locked and inaccessible.
