Imagine a technology that makes it possible to trust anyone. Now imagine your bank, your mortgage and all your assets are all built with that technology. This is certainly not our present, but it could be our future.

Blockstream is a group of people who share a vision of how to transform global systems of value exchange that, by design, put you first.

Blockstream’s core area of innovation is sidechains, a technology focused on improving on the blockchain, the most powerful public utility for distributed trust systems.

Sidechains are blockchains that are interoperable with each other and with Bitcoin, avoiding liquidity shortages, market fluctuations, fragmentation, security breaches and outright fraud associated with alternative crypto-currencies.

How Sidechains Work

Blockstream was founded to develop new ways to accelerate innovation in crypto currencies, open assets and smart contracts. We’ve come together because we believe in the potential of bitcoin and blockchain technology to have a significant, positive social impact.

1. We believe in trustless and permissionless innovation.

In the grand tradition of TCP/IP and HTTP that gave rise to the modern Open Internet, and now underpin Bitcoin and blockchain technology, we aim to foster an ecosystem where new innovation can thrive. We seek to ensure developers, asset issuers and users have neutral and cryptographically-assured computing technology for all their financial needs.

2. We believe in fairness, openness and accountability in financial and asset systems.

We want to power interoperable markets that are fair and accountable. Openness, accountability and public ledgers should be the norm and should not require users to sacrifice privacy. We seek to empower users with trustable and secure financial mechanisms via public auditability of their transaction history without disclosing more than is necessary for the integrity of the blockchain.

3. We are in this together.

We believe there is an important need for a technology that can accelerate the evolution of crypto currency, open assets and smart contracts. We are a private company with a very public mission: the transformation of technologies of trust for the benefit of all.

A look at a few Questions and Misconceptions regarding Pegged Sidechains

Matt Corallo Matt Corallo

Since releasing our paper, “Enabling Blockchain Innovations with Pegged Sidechains,” we’ve been pleased with the overwhelmingly positive response from the Bitcoin community and also the enthusiasm for the kind of innovation sidechains can enable. We received close to 10,000 downloads of the paper, saw a number of excellent blog posts and critiques on sidechains, and over 3,000 people logged in for a Reddit AMA with us to discuss the paper and Blockstream. However, we noticed a handful of comments that reflected some misconceptions and a few concerns regarding our integration into the Bitcoin ecosystem that we thought it would be helpful for us to address now, while the discussion is still ongoing. I’ve pulled them together into six questions and worked with the other authors to provide responses. What can (and what can’t) a two-way pegged sidechain accomplish? A sidechain is a general term for a chain that “validates data Read More…
