Cardstack is building a decentralized software ecosystem, which offers end users a beautiful, cohesive user experience across decentralized apps (dApps) and software makers and miners a fair distribution of rewards based on usage.
Cardstack is pioneering a new scalable consensus approach called Tally to augment on-chain smart contracts with off-chain number crunching, in order to attribute and allocate payments to a network of software makers, cloud service providers, and analytic miners proportionally.
