ReplaceTrust MewithImmutability

Cornicular is a blockchain based platform that provides a solution for all matters regarding digital file authenticity. We enable individuals and organizations to manage digital file processes, such as signing and establishing ownership, and guarantee file integrity instantly through a transparent, tamper proof system.

By providing immutable hash records, we ensure that every file can be traced back to its original source. Our system allows the authenticity of your valuable files to be verified without relying on intermediaries, thereby building trust based on transparency rather than authority.

Nothing is illusory without exception

Everything is designed for your digital needs, without compromise, loopholes, or artificial contrivances.

Sign & Request

Request and collect digital signatures with recipients, backed by an immutable blockchain audit trail.

Signature Status

Who has signed and track pending recipients.

Onchain Asset Protection

Secure your digital files or creative works permanently with blockchain proof of existence.

Contract Intelligence

Detect risks, ambiguous, and loopholes in clauses.

IPFS Storage

Pin your files to IPFS for decentralized availability, or choose to keep them private on your trusted storage.

Tracking

Track all changes status and anomalies.

Audit Trail

Immutable event history for every action.

One circle, up to blockchain examination

Solution covering every stage of your digital file, from signing to on-chain proof.

Everything You Need to Know

Clear answers about file registration, verification, privacy, and ownership.

Blockchain registration involves creating a cryptographic hash (fingerprint) of your file and storing that hash on a blockchain network. This proves the file existed in that exact state at that specific time, without storing the actual file contents publicly.

No. Only the cryptographic hash is stored on the blockchain. Your actual file remains securely in your connected storage (like Google Drive, AWS S3, or IPFS). This ensures privacy and compliance with data regulations.

Yes. Validation and scanning on Cornicular run based on the owner's permissions and plan. When the owner allows it, anyone can verify the file's authenticity and scan it through the system. If the owner does not grant permission, or their plan does not support private verification and scanning, the public can only verify the hash on the blockchain explorer, where the record stays transparent and traceable.

IPFS is a decentralized, peer-to-peer storage network where files are addressed by content, making them resilient and tamper-evident. BYOS (Bring Your Own Storage) lets you connect your own storage, like Google Drive or AWS S3, so your files stay under your control while Cornicular only hashes and anchors them. Gas is the network fee paid to execute blockchain transactions, and Cornicular covers it on plans that include Gas, so you never need crypto on those plans, while on plans without it the transaction fee is paid directly. Custody is where Cornicular can store, back up, recover, and manage your files and assets on your behalf.

Not on paid plans, where Cornicular abstracts away wallets, gas fees, and cryptocurrencies, so you pay a simple subscription in fiat and we handle the network mechanics. On the free plan, gas is not included, so you need your own cryptocurrency wallet to cover the transaction fees for on-chain registration.

Contract Intelligence analyzes your contracts and agreements, extracting key terms, risks, obligations, and status so you understand what you are signing. Notarization is the process where an authorized notary certifies the identity and authenticity of your file, giving it legal weight, and Cornicular binds that certification to the on-chain record. Legal Advisory provides guidance on how your registered files hold up in disputes, the compliance rules that apply, and the laws covering your digital records and agreements.

A Blockchain Consortium is a private, permissioned network jointly operated and governed by a group of organizations, where access and voting rights are granted to approved members instead of being open to anyone. While a public blockchain like Bitcoin or Ethereum lets anyone join, validate, and read transactions, a consortium restricts those roles to selected institutions, often combining the transparency and immutability of a distributed ledger with the privacy, speed, and regulatory control enterprises need. Members typically participate in governing the network, approving governance decisions, becoming validators, and committing to shared rules, so every record written on it is verified by trusted parties rather than anonymous miners. For Cornicular, a Blockchain Consortium means enterprises can create their own private blockchain network where their customers can register files and agreements, verify records, and share data in a permissioned and accountable environment that remains credible for legal, compliance, and audit purposes, all while keeping each member's data private and access controlled.
