with @guywuolletjr @eddylazzarin @smc90 "Which blockchain should I build in?" Is a very top of mind question for builders in web3, but also relevant to anyone interested in tech innovation and the evolution of infrastructure. So how does one decide among all the chain choices out there, particularly given how fast-moving the crypto and web3 space is? We sketch out the landscape, why it matters, tradeoffs; and then address common questions, a framework for deciding, different technical specs, and other factors such as community, marketing & ecosystem support, security, custody, programming languages, and more.
