Use Bitcoin without fees.
In less than 5 minutes.

The crypto manias of 2017 and 2021 saw the price of cryptocurrencies spike as well as their fees. In this image, the normalized fees in USD for an average Bitcoin transaction between December 2020 and May 2021 are plotted. In April 2021, the fee for one transaction surpassed 60 USD.

This is why we, at BitFlow, developed a patent-pending 2nd layer solution based on the Bitcoin network called the Cryptar protocol.

Using the Cryptar protocol, you can set up your own data anchoring node in less than 5 minutes and you will have unlimited throughput and transactions without fees – and this based on the strongest blockchain: the Bitcoin network.

Blockchains and cryptography.
More than one use case.

The Cryptar protocol supports data anchoring, data linking, and data revocation. Each transaction can be protected with one or multiple signatures. With this multiple use cases can be addressed.

Advanced Timestamping

The Cryptar protocol allows for timestamping in ways that weren’t possible using the ‘normal’ Proof of Existence. With Cryptar, timestamps can be linked together, which allows for the creation of a trail of records. Users can then refer to these records and track things like data changes over time. The signature mechanism, which is similar to that of Bitcoin, allows for the person or department who initializes changes to be recorded. These records can also be reviewed years later if needed.

Identity Management

Managing digital identities, like DIDs specified by W3C, is tricky as identities not only need to be issued by an authority, but they also need to be maintained over a very long time period. The Cryptar protocol supports not only the registration of new identities but also the update and revocation of identities that are already existing – all without hosting a centralized revocation list like what is currently required for certificate authorities issuing SSL certificates.

Smart Contracts

Smart contracts, mainly known from the Ethereum network, are used to manipulate a (global) state and store this new state as proof on the Ethereum network. Cryptar allows for smart contract execution, utilizing IPFS with replication nodes as data storage. The smart contract code is stored at the time of Blockchain creation, while each exaction of the smart contract is recorded by linking the new state utilizing the Cryptar protocol.

The Cryptar protocol is intended as a service solution utilizing Bitcoin as the blockchain rather than creating yet another token or blockchain.

All Cryptar protocol executions are signed with one (or more) private keys that you – and only you – have access to. After the signatures are applied the data will be anchored to the Bitcoin blockchain. With this you created an temper resistant proof.

Those proofs are also valid in court in most of the jurisdictions (US, EU (EU-qualified timestamping), Japan, Brazil, UK, Dubai, …) as direct evidence in court. In other cases an expert testimonial will make them valid in court.

Free Timestamping.
Forever.

You can test the Cryptar anchoring feature (aka as timestamping) for free. Simply drag and drop a file in the file section and we will anchor your hash to the Bitcoin blockchain. You will receive the anchoring proof within 6-8 hours. The data of this file will be private only to you (we receive only the SHA256 digest). Don’t trust us, verify the source code or use our API endpoint for free SHA256 anchoring.

If you want to do more cool stuff like linking existing timestamps or revoke them check out our use cases here.

Don't trust.
Verify.

Development of software for a pipeline stress test with automated verification of all test results on the Bitcoin blockchain. Test results are temper proof now.

Validating university diplomas, work experience and after submitting the documents to the Blockchain will store them for ever and let users access and proof the validaty anytime.

Understanding Bitcoin is difficult. That's why we support Bitcoin1x1 and give lectures to graps the technical insights of Bitcoin.

Secure your workflows with cryptography.
And blockchain technology.

We are happy to discuss your individual use cases with you and help you to setup the Cryptar protocol in your cooperation.
