Holochain Somewhat similar, but more open. https://holochain.org/. They once tweeted "Holochain is the solution for Climate Change". "Securing the Holochain chain requires no mining which causes it to have a minimal carbon footprint". Rather than using the entire ecosystem to provide consensus, they use 7 random witnesses.
"Holochain starts with a fundamentally different perspective from either blockchain or client/server architectures: an acknowledgement that all information has its origin in the subjective experience of the agent (usually a person) producing it, and the argument that data separated from its provenance has lost a critical part of its meaning (Harris-Braun, 2021)."

An application (https://developer.holochain.org/references/) The DNA is what lives in Holochain and is written in Rust.
On the thermodynamics of Bitcoin, Dogecoin, Ethereum, and Holochain Posted 21 May 2021
Public blockchains consume so much electricity because they have a lot of entropy to deal with. In thermodynamics, entropy is noise, waste, meaninglessness. The problem blockchain is trying to solve — dishonest agents trying to corrupt the global ledger — certainly fits that description. Any time you have too much entropy, you’re going to need to spend a lot of energy moving it somewhere else. My hot take: Bitcoin is basically converting dishonesty into CO₂. It’s simple physics.
