Avalanche is a high throughput smart contract blockchain platform. Validators secure the network through a proof-of-stake consensus protocol. It is said to be fast, low cost, and environmental friendly.
Mainnet was launched in September 21, 2020. Since then, the platform has grown to secure over 100+ individual projects, $1.4M+ of AVAX burned (reducing supply), 950+ individual block-producing validators, and over 500k+ community members around the globe. Decentralized finance (DeFi) applications can be found on Avalanche such as Pangolin, TraderJoe, and more.

FANTOM is a new DAG based Smart Contract platform that intends to solve the scalability issues of existing public distributed ledger technologies.
The platform intends to distinguish itself from the traditional block ledger-based storage infrastructure by attempting to employ an improved version of existing DAG-based pro-tocols. The FANTOM platform adopts a new protocol known as the “Lachesis Protocol” to maintain consensus. This protocol is intended to be integrated into the Fantom OPERA Chain. The aim is to allow applications built on top of the FANTOM OPERA Chain to enjoy instant transactions and near zero transaction costs for all users.
