Portal - DeFi on Bitcoin

Uncensorable Internet, Built on Bitcoin

Fabric allows building peer to peer, decentralized and censorship resistant applications as many layers on Bitcoin.

Fabric provides webscale, serverless infrastructure with strong privacy and security guarantees.

Fabric is a general-purpose "computation market", in which users are able to deploy complex programs for blinded execution by a network of peers. Using cross-chain atomic swaps, Bitcoin bonded in “requests for computation” assures proof of performance and payment.

Fabric extends Bitcoin’s functionality today without needing any BIPs.

DeFi on Bitcoin

Finally, Decentralized Finance comes to Bitcoin natively, with Portal’s revolutionary layer 2 P2P network that provides fast, cross chain, non-custodial trading. Using Portal swaps and moving provable execution of these contracts to layer 2, you get the speed and liquidity of centralized alternatives, with the trust minimization guarantees of Bitcoin.

Portal swaps

Portal swaps are the fastest, easiest, most secure and private way to swap your assets and contracts at all times. Read more about revolutionary Portal Swaps here. Portal contracts incentivize liquidity and order book execution among exchange facilitators, who get rewarded for their effort, proportional to their contributions, using self-enforcing contracts.

Portal allows peer-to-peer atomic cross-chain transactions with the speed and security of centralized exchanges, but with the privacy and security of underlying blockchains.
Portal supports not just simple exchange but arbitrarily complex financial contracts as well.

Privacy

Recent advances in Fully-Homomorphic Encryption (FHE) have reduced computational requirements to a domain in which real-world users may find tolerable, in the range of 30 seconds to two minutes for small, well-defined programs. Fabric's design relies on Yao's garbled circuits model for Secure Multi-Party Computations.

Layers on Bitcoin

Fabric lets you spin up your own secure layer two peer-2-peer network using Bitcoin blockchain as the trust anchor. Your peer-2-peer network is secured by Full homomorphic encryption which assures privacy, without requiring another consensus mechanism.

No New L1 Consensus

Why no consensus of our own?: Because we don’t need another “Layer 1 blockchain”. We defer consensus on a global state to an underlying trust anchor, the Nakamoto Consensus of Bitcoin's blockchain.
