Blockchain enables the exchange of value in real-time for free through a shared digital ledger. It works by automatically verifying rules and executing agreed terms through smart contracts. This transitions processes from opaque to transparent and efficient by disintermediating intermediaries, establishing audit trails, and reducing costs. Cryptocurrencies have surpassed early VC funding for blockchain startups. While adoption is still low, there is significant upside potential as anything could exchange value anywhere through blockchain in 5-10 years. Crypto assets provide diversification as they have low correlation to traditional assets and higher returns.
