Since its inception, Ethereum has maintained its spot as the second-largest cryptocurrency by market capitalization. But like every other blockchain network that exists, Ethereum is not perfect. Notable, the legacy blockchain is plagued with high gas fees and low throughput of between 15 to 30 transactions per second.
Although plans are already on the way to solve these shortcomings through several upgrades, many competitors have capitalized on this delay to offer crypto users cheaper and faster transactions.
The term “Ethereum Killer” emerged around 2016/2017 as substitute blockchains such as Cardano began to enter the crypto scene. In 2018, EOS made its debut as the next “Ethereum killer,” raising $4.1 billion from investors, the highest amount an ICO had ever generated. Since then, others like Tezos, Solana, Fantom, Avalanche and Binance Smart Chain have surfaced as possible Ethereum killers.
Each of these blockchains employs a different consensus model to tackle Ethereum’s PoW-induced limitations. For instance, Solana uses proof-of-history (PoH) while Binance Smart Chain utilizes both proof-of-authority (PoA) and delegated proof-of-stake (DPoS).
However, none of these alternative blockchains have been able to unseat Ethereum as the second-largest cryptocurrency by market cap. Ethereum is also currently the largest blockchain for NFT trading activities.
