In this episode of The Steemit Podcast, Senior Blockchain Engineer at Steemit (@vandeberg) explains Steem's revolutionary Resource Credit system which is the key to making Steem the best freemium blockchain in the world for powering applications. While other blockchains like Bitcoin and Ethereum use transaction fees to allocate resource consumption by the network, Resource Credits enable Steem to allocate resources without charging any fees at all, while still preventing spam and bloat. In this episode, we learn more about this under-appreciated system, and why Steem is uniquely suited to benefit from this system unlike general-purpose protocols like Ethereum.
