March 03/01/2021 - Portal has merged with Fabric project. Read more about the Fabric project and how it fits into Portal’s mission here
Build unstoppable applications that leverage the security, censorship resistance, liquidity and the largest user base of Bitcoin network.
Asset Swaps, Lending, Borrowing, Staking, Liquidity, Derivatives and other Financial Services built on bitcoin, securely accessible from your wallet.
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 is a layer 2 system purpose built to facilitate cross chain atomic transactions. It is like lightning network in that it is layer 2, but unlike lightning which is designed for peer to peer payments, Bridge(swaps) is designed for cross chain atomic exchange.
Portal swaps are the fastest, easiest, most secure and private way to swap your assets and contracts at all times.Read whitepaper
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.

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, digital currency bonded in the initial request for computation assures proof of performance and payment.learn more
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.
A 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.
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.

"We are excited to have the incredible team at Fabric join us" said Portal founder and CEO Dr.Chandra Duggirala. We have been working together for 3 years building unstoppable financial tools on top of Bitcoin, but we finally decided to join forces. Everyone at Portal has enormous respect for Eric and the team he has built and what they have built over the years. We had a blast working with them to build censorship resistant applications on top of Bitcoin, and making other chains operate seamlessly with Bitcoin. We are super excited to now have one of the most experienced and talented teams in cryptographic protocols, together, going after a gigantic vision".
As part of this merger, Eric Martindale becomes the CEO of Portal, and Chandra Duggirala (chairman), Manoj Duggirala and George Burke have joined the Portal board.
