hyperledger - Hyperledger Project is a new Collaborative Project at The Linux Foundation

•    

---

Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration including leaders in finance, banking, Internet of Things, supply chains, manufacturing and Technology. The Linux Foundation hosts Hyperledger under the foundation. Not since the Web itself has a technology promised broader and more fundamental revolution than blockchain technology. A blockchain is a peer-to-peer distributed ledger forged by consensus, combined with a system for “smart contracts” and other assistive technologies. Together these can be used to build a new generation of transactional applications that establishes trust, accountability and transparency at their core, while streamlining business processes and legal constraints. Think of it as an operating system for marketplaces, data-sharing networks, micro-currencies, and decentralized digital communities. It has the potential to vastly reduce the cost and complexity of getting things done in the real world. Only an Open Source, collaborative software development approach can ensure the transparency, longevity, interoperability and support required to bring blockchain technologies forward to mainstream commercial adoption. That is what Hyperledger is about – communities of software developers building blockchain frameworks and platforms.

clay - Golem is creating a global market for computing power.

•    Python

---

⚠️ Clay Golem (ex. Brass Golem) has been discontinued. The current, completely new incarnation of Golem is called yagna and developed within a separate set of repositories. Golem is a decentralized marketplace for computing power. It enables CPUs and GPUs to connect in a peer-to-peer network, enabling both application owners and individual users ("requestors") to rent resources from other users’ ("providers") machines. These resources can be used to complete tasks requiring any amount of computation time and capacity. Nowadays, centralized cloud providers are in control of these services, these platforms are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Golem proposes an open-source, decentralized and user controlled alternative.
