Proof of Existence 2.0

Po.et is a shared, universal ledger designed to track ownership and attribution for the world's digital creative assets.


Po.et reclaims value for content creators, publishers and consumers

Own Your Content

Generate immutable and timestamped titles for your creative works and register your assets to the Po.et network. Because it is decentralized and secured by the blockchain, the metadata attribution remains safe, verifiable and immutable.

Create and Issue Licenses

Po.et uses cryptography to give both publishers and content creators the tools to automate the licensing process without relying on any third parties. Choose from a preexisting license or create your own terms and automate the payments, transfer and issuance of licenses.

An Open Network

Providing an open network in a space that had always been controlled by third parties, Po.et builds a bridge between creators and publishers. Discover new content or verify authenticity, authorized through a truly transparent system of attribution.

An Open Network

Blockchain-based hashing and time stamping ensures irrefutable evidence of existence and the integrity of data.


The Bitcoin blockchain is public and fully distributed. Anyone can access it anywhere. For the first time, publishers and content creators have a trustworthy holistic view of the integrity of digital assets’ origins and respective derivative data.


Po.et’s data is secured by the most powerful computing network in the world, the Bitcoin mining network. Cryptographic signatures guarantee the integrity of data and identity of parties interacting on the Po.et network.


The Po.et network is not run by any one company, organization or administrator. Because of this, Po.et has no single point of failure.


Want to use Po.et but not share your content publicly? Want to invent your own licensing terms? Want to build a new smart contract? You can do all of that using Po.et.

Open Source

Anyone can extend or modify Po.et to meet their needs. Build the future of academic research, meme libraries or anything else.
