Grigore Roșu argues that the future of Web3 may not be intrinsically tied to blockchain technology. While blockchains like Bitcoin and Ethereum have established their importance by solving problems like double-spending, they impose significant limits on scalability and flexibility due to their need for total ordering of transactions. Roșu suggests that decentralization can be achieved through alternative payment systems that focus on speed and scalability, such as FastPay, which avoids the rigid sequencing required by blockchains. Despite blockchain’s role in establishing trust through transaction verification, the constraints it imposes are becoming increasingly untenable as more advanced decentralized applications emerge. Roșu believes that the evolution of modular blockchain frameworks is a sign of changing needs within the industry, pointing toward a future where blockchains serve primarily as decentralized notaries rather than as central ledgers. This transition is essential for those in the Web3 ecosystem to remain competitive and fully adapt to emerging technologies.
