This smart contract focused blockchain network is significantly revolutionising the crypto ecosystem. At the core, Ethereum introduced a blockchain network where developers can build a wide range of DApps based on its smart contract architecture. This has given rise to promising niches, including Decentralized Finance (DeFi) and Non-fungible tokens (NFTs). However, the growth has come with its fair share of challenges. Ethereum faces a massive scalability issue, given the current Proof-of-Work (PoW) based chain can only handle an average of 30 transactions per second. The slow nature of this blockchain has forced its community to come up with long-term solutions, with the most notable being Ethereum 2.0, where the network will fully transition to a Proof-of-Stake (PoS) consensus.
