In the alley, Blockstream is a topic of conversation,a service that streams Bitcoin transactions and blocks in real time from multiple satellitesso that people from all regions of the world can freely access the Bitcoin network…!

“Blockstream Satellite”is already available in two-thirds of the regions on Earthand by the end of 2017 its coverage is expected to expand to the entire planet, making it accessible to everyone.

Regarding Blockstream, I have translated into Japanese the official site and the official blog post announcing Blockstream Satellite, and I’d like you to read it.

Blockstream’s Vision (from the official site)

Financial Network Ecosystem

Imagine technology that enables you to transact safely without needing to trust third parties. Now imagine your bank, your mortgage, and all of your financial assets built with that technology. This is currently not achievable, but it may become possible in the future.

Blockstream’s main area of innovation isSidechains. Sidechains are a technology invented to extend the functionality of the Bitcoin blockchain. Sidechains open up possibilities for new models of reliability, expanding and improving Bitcoin’s properties.

Cross-Chain Interoperability

Making our world more seamless means ensuring that today’s systems integrate smoothly. To coordinate and operate systems together, interoperable protocols will be required.

With sidechains, it becomes possible to move digital assets between blockchains.By coordinating with other systems, you can connect distributed markets using sidechains and provide liquidity through shared protocols.

New Systems, New Rules

Imagine all financial institutions around the world operating under a system that lacks transparency and adheres to pre-decided rules. If someone tries to do something wrong, the system would make it obvious worldwide.

One premise of crypto-financial networks is a highly reliable financial system. To build such reliability, a new model of trust is needed, and sidechains provide the platform to construct it.

Blockstream Overview

Blockstream is a leading provider of blockchain technology, operating at the forefront of cryptography and distributed systems. Our mission is to solve the problems that undermine trust in today’s financial system, from fraud and forgery to security, confidentiality, accountability, and transparency.

Blockstream offers a broad range of software and hardware solutions, along with highly specialized professional services, to enterprises deploying blockchain-based new networks.

Our core software platform, Elements, was released as part of the open-source Elements Project. It is now the most mature protocol for blockchain developers. Together with PwC and a growing network of partners, we combine advanced technology with world-class expertise to provide cross-industry and cross-use-case solutions.

Core Values

We support permissionless innovation.

In the great tradition of the open Internet—TCP/IP and HTTP—we aim to build an ecosystem where new financial innovations can thrive. We strive to create an environment where developers, asset issuers, and users alike can access fair, cryptographically guaranteed computing technologies that meet their needs.

We believe thatfairness, openness, and accountability are essential.

We want to support interoperable markets that are fair and accessible, where openness, accountability, and public ledgers are a given, and where users should not have to sacrifice privacy to use them. We will enable trustworthy and safe financial mechanisms that users can rely on—keeping transaction histories openly auditable without disclosing more information than necessary to prove fairness of the blockchain.

We believe in universal programmable reliability. We are a private company with a mission for public benefit. For everyone's benefit, we will drive reforms in reliability-related technology.
