Capital allocation, from paying bills to complex organizational funding, often suffers from inefficiencies and lack of transparency.

By addressing coordination failures and introducing new onchain strategies, crypto could transform how society allocates resources, similar to how the internet revolutionized information sharing. This book explores these possibilities within the web3 space, offering a comprehensive guide to the emerging innovations in capital allocation.
