New guidelines from U.S. regulators allow banks to become validators on blockchain networks, marking a significant advancement in institutional adoption but also intensifying centralization risks. Bohdan Opryshko, COO of Everstake, stated that banks' participation in proof-of-stake (PoS) networks like Ethereum and Solana could lead to a concentration of power, undermining the decentralized characteristics of the network. Furthermore, significant participation by banks may depress staking yields, affecting the interests of smaller validators. Nevertheless, this initiative could also bring more capital inflow into PoS networks.
