Assemble your app with these existing WordPress Gutenberg Blocks and perform Bitcoin blockchain integration with 10 different Catenis powered blocks. The future is here and now.


Power with total flexibility

Catenis’ robust APIs ensure there is ZERO BACKEND DEVELOPMENT required for Bitcoin blockchain integration. Our frontend tools provide all the flexibility you need. Want complete flexibility? Use the Integrated Development Environment (IDE) you love and the language you are most comfortable with. We understand, sometimes you want to know you’re never locked into any tools.

We know you have questions


We don't have our own blockchain. Catenis uses the premiere, proven, and most secure blockchain in the world, The Bitcoin blockchain. Catenis is a second-layer technology that allows you to use the global Bitcoin blockchain while enhancing its network’s capabilities.

We have developed a second-layer technology that allows content of any type or size to be transmitted globally in the blink of an eye. Catenis uses the Bitcoin blockchain and all of its facilities, so ultimately all Catenis messages are anchored as bitcoin transactions on the blockchain. We abstract out all the messy, complex stuff so that you can build applications fast and with ease.

No, your content is never public and always Only the hash of the encrypted data is stored on the Bitcoin blockchain. Catenis defaults automatically to AES (Advanced Encryption Standard), encrypting all content while using perfect forward secrecy for every message thread.

However, you have the option to send unencrypted content at will. You can read more about our message encryption here.

No, you never have to buy, use, hold, or store bitcoins. Catenis uses a complete non-custodial system via what is called the Catenis Credits. These credits are encoded on the Bitcoin blockchain,and as you use our services, we only charge for transactions that incur a Bitcoin fee. Our second-layer transaction messages (off-chain messages) start at USD $0.25 (twenty-five cents) and can go as low as pennies. Usage fees come from your Catenis Credit account. When opening an account, your account will come loaded with 1,000 Catenis Credits (3,000 FREE Transaction Messages), and you can easily purchase more if needed with a credit or debit card.

Catenis defaults to using IPFS, an industry-proven decentralized file storage solution for all content above 75 bytes. This content is encrypted with military-grade encryption. If you require a different storage location, contact us, and our Professional Services team can build integration into 3rd party content management systems.

The development plan comes with the full power of the Catenis product. The only difference is it uses Bitcoin's TestNet to build and test your applications. It is best to begin with the Development Plan. Then when you are ready to deploy, you can purchase our production plan license to deploy what you built to the Bitcoin MainNet blockchain. 

Actually, it is a misnomer that bitcoin is expensive. Catenis transaction messages default to off-chain messages using our proprietary layer 2 technology. These TX messages are in real-time and are eventually logged to the blockchain via a single bitcoin transaction in aggregate. This allows us to achieve high throughput while inexpensive transaction messages are still verifiable via the Bitcoin blockchain. We also support standard bitcoin transaction messages but recommend always using our off-chain second-layer technology.

We are confident that after you start using Catenis, you will realize private blockchains are a thing of the past. Private blockchains are riddled with trust issues and a lack of transparency. Catenis' layer 2 technology not only allows you to encrypt all your content but also includes a permission layer that can be set to allow or deny which apps or devices can communicate and access transmitted content. All transaction messages are represented by Bitcoin addresses and verifiable on the Bitcoin blockchain.  You can read more about our permission model here.

You can use any development language on our platform! Catenis does not suffer from language limitations. We provide very robust low-code drag-and-drop tools and prebuilt blocks for WordPress. Applications can be built with any language you or your engineers feel comfortable using. You can even use compiled languages such as Rust or C to protect your intellectual property.

Using Catenis, you can build an application from scratch or integrate an existing application with the Bitcoin blockchain. Any application built today on proprietary blockchains can be built using Catenis, leveraging the Bitcoin blockchain. From sending content of any type or size, including mp3s, mp4s, and cad files, to logging data for supply chains or medical applications, Catenis has you covered.

However, we do not support applications that require the transmission or receipt of bitcoins.

With Catenis, you can prototype rapidly and test your applications with powerful drag-and-drop tools. You also never need to incur risks by buying or holding bitcoins. You get all of the advantages of using the Bitcoin blockchain while gaining enhanced functionality with the power of Catenis. Catenis provides many facilities across its second-layer technology that the Bitcoin blockchain lacks, such as permission model, notification layer, encryption, speed, and lower message transaction costs.
