Hyperledger Releases Hyperledger Sawtooth 1.0

  • Second production-ready framework launched by The Linux Foundation’s open blockchain consortium

    SAN FRANCISCO, CA – (January 30, 2018) – Hyperledger, a collaborative cross-industry effort created to advance blockchain technology, announced today the general availability of Hyperledger Sawtooth 1.0. Hosted by The Linux Foundation, Hyperledger Sawtooth is a modular platform for building, deploying, and running distributed ledgers. Hyperledger Sawtooth is the second active Hyperledger project to reach 1.0, following Hyperledger Fabric 1.0 in July 2017.

    “We’re beyond excited to see not one, but two of Hyperledger’s active projects hit 1.0,” said Brian Behlendorf, Executive Director, Hyperledger. “This is a huge testament to the strong collaboration of our growing community – I look forward to seeing even more products and services being powered by Hyperledger Sawtooth later this year.”

    Hyperledger Sawtooth is an open source distributed ledger framework and one of the nine business blockchain and distributed ledger technologies hosted by The Linux Foundation. Hyperledger Sawtooth delivers unique capabilities. A few examples are included below:

    • On-chain governance – Utilize smart contracts to vote on blockchain configuration settings such as the allowed participants and smart contracts.
    • Advanced transaction execution engine – Process transactions in parallel to accelerate block creation and validation.
    • Support for Ethereum – Run solidity smart contracts and integrate with Ethereum tooling.
    • Dynamic consensus – Upgrade or swap the blockchain consensus protocol on the fly as your network grows, enabling the integration of more scalable algorithms as they are available.
    • Broad language support – Program smart contracts in your preferred language, with support including Go, JavaScript, Python and more.

    The efforts around Hyperledger Sawtooth have grown significantly; from the initial code contribution in April 2016, to Active status graduation in May 2017, to today’s version 1.0 availability. Hyperledger Sawtooth is supported by an active community: organizations including Amazon Web Services, Active Ticketing, Bitwise.io, Cloudsoft, Context Labs, Dot BC Media, Ericsson, Hacera, Huawei, IBM, Intel, Microsoft Azure, Monax, Open Music Initiative, PokitDok, R3, T-Mobile, Wind River and more than 50 engineers have contributed to the project. Additionally, Proof of Concepts (PoC’s) have been deployed to support multiple business cases including music and media content rights attribution, recording healthcare transactions, Know Your Customer (KYC) in financial services and others.

    Hyperledger aims to create common distributed ledger technology that enables organizations to build and run robust, industry-specific applications, platforms and hardware systems to support their individual business transactions. The project has grown to more than 185 members since its inception, spanning various industries including finance, healthcare, the Internet of Things, credit card services, supply chain and aeronautics, among several others.

Tmux Commands

screen and tmux

A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

It should be noted that this is no where near a full feature-set of either group. This - being a cheat-sheet - is just to point out the most very basic features to get you on the road.

Trust the developers and manpage writers more than me. This document is originally from 2009 when tmux was still new - since then both of these programs have had many updates and features added (not all of which have been dutifully noted here).
