The article discusses the importance of blockchain technology in Web3 applications, but also highlights the challenges that come with it. It emphasizes the need for a public ledger or blockchain to verify transactions and enable secure peer-to-peer trading of digital assets. However, the security and transparency of a blockchain can lead to scalability issues, especially when building a Web3 app closely tied to a blockchain. The article suggests that storing as little data as possible on a blockchain is crucial for future-proofing Web3 apps. It also recommends using Apache Cassandra® or DataStax Astra DB for database solutions due to their scalability and performance capabilities.
