Kontor is a next-generation Bitcoin metaprotocol that brings programmable assets, scalable file storage, high-throughput and low-latency execution directly to the Bitcoin blockchain.
Current Status: Kontor is under active development with Bitcoin signet support. For the latest updates, please see the Kontor website.
Fast and Scalable
Kontor’s optimistic consensus layer provides transaction confirmations in 1–2 seconds while Bitcoin remains the ultimate source of finality. Bundling amortizes Bitcoin transaction fees across thousands of operations, bringing per-operation costs down significantly. Combined with BLS signature aggregation and compact data encoding, Kontor processes over 1,000 transactions per second—all entirely on the Bitcoin blockchain.

Smart Contracts with Sigil
Write, deploy and run rich smart contract applications directly on the Bitcoin blockchain. The Sigil framework uses the WebAssembly Component Model to make writing contracts easier than ever before, with strong type safety, native cross-contract calls and best-in-class developer ergonomics.

Perpetual File Storage
Pay once, store forever. Kontor’s storage protocol provides scalable, permanent file storage where the data lives off-chain but the storage system itself is entirely on-chain. Kontor supports files from kilobytes to gigabytes with logarithmic cost scaling and strong security guarantees.

Kontor Economics
The Kontor economic model was designed from first principles to support data storage and smart contract execution. BTC remains the unit of account while KOR meters execution and incentivizes storage through perpetual emissions. Dynamic mechanisms ensure network health and long-term sustainability.
