The most prominent upgrade in the history of the network, however, is due in 2022. Ethereum 2.0, as they call it, aims to remove bottlenecks and scalability issues while bringing the long-awaited proof-of-stake (PoS) consensus mechanism to the blockchain. On 20 November, Polygon announced it was shifting to Polygon PoS on Uniswap, one of the biggest decentralized exchanges in the world. Major protocols like Aave and Sushiswap have already migrated to Polygon to avoid Ethereum’s fees. These groundbreaking developments also make MATIC a promising crypto project to watch in 2022.While Solana was not the first network to implement smart contracts, it now has more than 350 different projects running on its network. It also returned more than 17,000% of its value in the past 12 months, currently ranking as one of the top 10 coins by market cap, valued at $53 billion approximately.
