William Mougayar, author of 'Blockchain Business Applications,' has redefined Ethereum as a coordination layer rather than a traditional blockchain. Mougayar describes Ethereum as an organic consensus network that enhances creativity, sovereignty, and logic, positioning it as a programmable protocol for value, identity, and collaboration. He contrasts Ethereum with traditional databases and closed systems like Solana or BNB Chain, highlighting its role as a self-sustaining, open, and evolving protocol that transforms human collaboration in the digital era.
