Overview

Low trust interaction protocols are a Layer 1 component.

Ethereum

Overview

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference.

These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.

Bitcoin

Overview

Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

Zcash

Overview

Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.

Polkadot parachains

Overview

A parachain (parallelizable chain) is a simpler form of blockchain, which attaches to the security provided by the [[Polkadot|Polkadot]] Relay Chain rather than providing its own. The Relay Chain is called that because it not only lends security to attached parachains, but also provides a guarantee of secure message-passing between them.

Substrate blockchains

Overview

Substrate is a product created by Parity Technologies and is Parity's implementation of a [[Polkadot Runtime Environment|Polkadot Runtime Environment]]. Substrate is a software development framework to build blockchain technologies. Substrate can be used to create standalone blockchains or to build (native) [[parachains|Parachains]].
