Holochain

Unprecedented interoperability and scalability for blockchain developers who want to quickly push the limits of what’s possible. Built using Substrate with nearly the same codebase and industry-leading multichain infrastructure as Kusama’s cousin, Polkadot. The relationship between society and technology has deteriorated to the point where large entities routinely stretch and overstep their authority. Kusama is a network built as a risk-taking, fast-moving ‘canary in the coal mine’ for its cousin Polkadot. It's a living platform built for change agents to take back control, spark innovation and disrupt the status quo. Move fast and ship your product. Kusama’s risk-taking and nimble mentality allows developers to move swiftly through the governance and upgrade process, enabling rapid progress and growth. Build on a next-generation, sharded, multichain network, while employing the newest features before they are deployed on Polkadot.

Hedera is owned and governed by the world's leading organizations. Hedera is the most used enterprise-grade public network for you to make your digital world exactly as it should be – yours. HBAR is the native, energy-efficient cryptocurrency of Hedera that powers the decentralized economy. Whether you're a startup or enterprise, a creator or consumer, Hedera goes beyond blockchain for developers to create the next era of fast, fair, and secure applications. Bitcoin pioneered decentralized infrastructure and Ethereum brought programmability. But earlier proof-of-work blockchains consume massive amounts of energy and process transactions slowly in order to achieve acceptable levels of security. Heavy bandwidth consumption by these technologies leads to expensive fees, even for a simple cryptocurrency transaction. The Hedera proof-of-stake public network, powered by hashgraph consensus, achieves the highest-grade of security possible (ABFT).
