Real World Assets (RWAs) – like tokenized real estate, commodities, or bonds – are increasingly brought on-chain, often via Ethereum DeFi protocols. This unlocks liquidity for traditionally illiquid assets and merges traditional finance (TradFi) with DeFi, expanding the scope and utility of Web3 financial systems

Modular blockchains like Celestia and EigenDA are challenging traditional monolithic architectures by separating core functions (execution, consensus, data availability) into specialized layers. This approach enables greater scalability by allowing each layer to optimize independently. Rollups can leverage modular chains for affordable data availability, while validators focus solely on consensus. Though still in early stages, modular designs promise to solve the blockchain trilemma (scalability, security, decentralization) more effectively than all-in-one solutions. The success of this model may determine whether blockchains can support mass adoption.

Proof-of-Work (PoW) and Proof-of-Stake (PoS) are blockchain consensus mechanisms. PoW, used by Bitcoin, relies on miners solving complex puzzles, ensuring high security but consuming significant energy and processing transactions slowly. PoS, adopted by Ethereum (post-2022), selects validators based on staked cryptocurrency, offering energy efficiency and faster transactions but risking wealth concentration. PoW is battle-tested for security, while PoS prioritizes scalability and sustainability. The choice depends on a blockchain’s goals—security for PoW or efficiency for PoS
