celo-extension-wallet VS homebrew-golem

You might consider taking a look at Celo. They have ultra-light client support [0], it's proof-of-stake with single-block finality, and they run a true EVM that you can program in Solidity. It's mobile-first but since it's fundamentally a fork of Ethereum it is also web3 compatible -- there's a metamask fork here that should soon be functional [1]. Gas is payable in multiple ERC20 tokens, and should remain cheap as the network scales. Not sure if this falls under your "ethereum killers that can do 10x transactions/second" so apologies for shilling if it's not interesting to you.

Golem, develop Docker applications and make use of their (now) very limited features. It's best suited for heavy calculations, or calculations you can split up between dozens or hundreds of nodes through sharding. A fork is working on bringing GPU & internet access, but it can be hard otherwise. They have a GLM Rewards Program that - generously rewards up to 20 users per month under regular conditions.

For compute, my experience has been the best with Akash, then Golem, then I have been unsuccessful with any other project as of yet. Both of these supports Docker images, but Golem is painfully thorough with securing providers with sandboxing in both networking and workloads. This makes Akash easier to use right now when wanting to run something more advanced such as a custom backend or a Minecraft Server.

If you want to run scientific calculations or similar, I highly recommend Golem. Right now, its best applications are ones that can scale by sharding, to use parallel computations. Think doing 100 similar small jobs on 100 computers instead of 1 large job on 1 computer. One average CPU-month costs $3.17, or you can rent 100 CPU-hours for $0.44. Notable examples are blender_cuda which runs on a GPU, and the entirety of awesome-golem.

if you're not using your computer, you can consider letting other people use it! come checkout golem, a distributed super computer similar to Folding@Home, but for all kinds of computation not just protein research. You even earn some money and it's really easy to get started.

This is where the math of VPS on demand for testing vs home starts to matter. OR higher buy in but lower ongoing is SBC boards. Raspberry pi, turingpi, ION whatever boards from nvidia. All have higher cost, more limited abilities (in some ways) but FOR SURE are way lower power/heat than traditional low initial cost/higher ongoing. It's a common issue. Getting yourself a NAS or ESOS or SAN or whatever as an always on, mount it on the projects you need as storage. Depends on what you want, but an always on computer can do a hell of allot. golem.network, idle mining, BOINC for science, etc etc. Dunno, GLHF

It is public and been running for a bit now, seeing as you asked I assume its ok for me to say its golem.network ? Definitely open though if you want to join

Run a golem.network node to rent out some pi's to others who can purchase their compute power, isn't much but glad to help someone when I'm not using it
