Solana co-founder Anatoly Yakovenko raised concerns about Ethereum’s layer-2 scaling networks’ decentralization and security. He pointed out that these networks have a large attack surface and code bases that cannot be adequately audited. Yakovenko also highlighted the risk of user funds being moved without consent due to multi-signature custody. The debate continues on whether layer-2 networks benefit or harm Ethereum’s layer-1 blockchain. Currently, there are 129 verified Ethereum layer-2 networks and 29 more that are not yet reviewed by L2Beat. According to Adrian Brink, the blockchain industry has about 10 times more layer-2 networks than needed, which could potentially impact Ethereum’s base layer revenue. Despite the concerns, some industry experts, like Igor Mandrigin and Anurag Arjun, see the proliferation of layer-2 networks as a positive sign of network growth and increased diversity in the ecosystem. However, Binance Research notes that these networks may be cannibalizing revenue on the Ethereum base layer due to their lower transaction fees compared to the layer-1 blockchain.
