Decentralization in blockchain technology is poised for significant advancements over the next 3-5 years, with breakthroughs expected in zero-knowledge (ZK) technology and node infrastructure. Key developments include ZK-based fully decentralized sequencers and client diversity that ensures long-term node decentralization with economic proof. Additionally, innovations in dual quorum and Cosmos-style pluggable security, along with true economic incentives, are anticipated to enhance economic security and resistance to attacks. These advancements could enable users to run nodes on affordable devices like Raspberry Pi, significantly reducing the costs associated with full node synchronization. Furthermore, the development of mathematically provable cross-chain security could provide a competitive advantage to the first Layer 1 blockchain to implement these technologies, potentially reshaping the landscape of blockchain security and decentralization.
