Kusama vs. Parity vs. Substrate vs. Urbit Comparison Chart

From the Substrate blockchain framework to Polkadot, the sharded protocol enabling blockchains to operate seamlessly together at scale, Parity builds the foundation of Web 3.0. We are developing the technology to disrupt centralised online services and enable institutional innovation. The internet is too important to billions of people for it to be at the mercy of a few powerful companies. We are developing the technology to disrupt centralised online services and enable institutional innovation. What if we no longer had to route our interactions through centralised services? What if data breaches were a remnant of an old flawed infrastructure? Each piece of Parity's technology is a step towards a society run on peer-to-peer networks instead of by a handful of corporations. Nearly all of our work is provided open source. Community contributors are a crucial part of development. Come build technology for a fairer society with us.

Urbit is for everyone, but sometimes it is easy to get lost in this universe. Follow these links to contribute to the network through developing, operating, and exploring. It solves the hard problems of implementing a peer-to-peer network (including identity, NAT traversal, and exactly-once delivery) in the kernel so app developers can focus on business logic. The entire OS is a single pure function that provides application developers with strong guarantees: automated persistence and memory management, repeatable builds, and support for hot code reloading. The connected world anticipated by Urbit is a much friendlier one, much like the early Internet, where collegial discussion and collaboration was the norm. Problems that are unsolvable without large-scale political centralization in our current internet – data breaches, spam, fake reviews, malware-spreading, harassment – become tractable when individuals control their computing again.
