The Cardano blockchain is a 3rd generation blockchain platform that was designed with a collaborative peer-to-peer review system, It aims to improve upon prior blockchain systems to enable larger and more sustainable uses of the technology.
Cardano was built with a governance model that is based on collaboration. This allows the platform to evolve quickly and adapt to the changing needs of its users. Unlike many other blockchain projects, it also installed a treasury system to fund the ongoing development needs that may arise as it moves forward.
The Cardano blockchain uses a unique proof of stake algorithm called Ouroboros and has a protocol that consists of two layers, a settlement layer and a control layer. The settlement layer is designed to perform accounting functions, while the control layer is tasked with running smart contracts. The platform tries to balance the privacy concerns of users with the requirements of regulators in an effective way.
Cardano uses the Haskell programming language and is fueled by the ADA coin

BurstCoin is a cryptocurrency with a Proof-of-Capacity (PoC) consensus algorithm. Unlike most other cryptocurrencies, Burst's architecture uses a Tangle (similar to IOTA) instead of relying on a blockchain. It also utilizes ring signatures and other features, in what is called the Dymaxion. The Dymaxion implements layers of tangle-based lightning networks on top of the Burst blockchain. Each of these payment channels is opened in the form of a standalone colored tangle. Burst is also developing atomic cross-chain transactions (ACCT), that will allow for full decentralized trading between two cryptocurrencies.

ICON (ICX) is unique compared to most other digital currrencies. ICON's primary objective is to establish a unifying system to integrate an unlimited numbers of blockchains. This would allow numerous blockchains to work together and incorporate aspects of all of them. ICON is powered by a unique system called loopchain, that can adopt different features, rules, and consensus systems. The loopchain has different circles, with nodes that connect it. There are community nodes and individual nodes that are all connected to the ICON Republic, which is the entire ecosystem. These nodes can connect in countless ways and results in unlimited applications. The network has an innovative consensus mechanism called Delegated Proof-of-Contribution (DPoC).
