Here are some additional coins and tokens that have social or environmental benefits:

(Descriptions are mostly taken from the linked websites and haven’t been evaluated by me for accuracy.)

“Power Ledger is a blockchain-based peer-to-peer energy trading platform enabling consumers and businesses to sell their surplus solar power to their neighbours without a middleman.” Power Ledger has been in the news recently for helping facilitate peer-to-peer sharing of solar power in Japan, Australia, the United States, and elsewhere.

“FoldingCoin Inc. distributes cryptocurrencies (tokens) to affiliated participants on the Stanford University Folding@home network. The tokens are awarded proportionally according to that participant’s Folding@home credits.”

Steemit is a bit like Medium, but with users earning cryptocurrency based on how much other users enjoy their content. “STEEM is the platform token on Steemit.com. It’s distributed to the most valuable contributors by community voting. STEEM is a tradeable token that is easily convertible to Bitcoin and Ethereum.”

Update: Since writing this article Medium has started paying some writers for their content, based on popularity with paying Medium members. This is still not quite the same as what Steem does, but it would be interesting to know what all went in to Medium’s decision.

“The defining characteristic of Einsteinium is its ongoing commitment to research and charitable missions. Einsteinium the coin is connected to the Einsteinium Foundation.

Einsteinium coin is a Bitcoin-like currency with a philanthropic objective of funding scientific research, cutting edge IT and crypto currency projects. Our community members vote on which valuable projects the funds will be awarded too.”

“Gridcoin is an open source cryptocurrency (Ticker: GRC) which securely rewards volunteer computing performed upon the BOINC platform in a decentralized manner on top of proof of stake.

BOINC is an open-source volunteer computing grid which combines the processing power of all individual users for the purposes of scientific research. It’s free, production ready and many projects already harness volunteered computing power to attempt to cure cancer/AIDS/Ebola/malaria, map the Milky Way galaxy, crack Enigma machine codes, etc..”

“SolarCoin is an alternative digital currency that works like air-miles for Solar electricity generation. SolarCoin is claimed by individuals living in homes with solar panels on their roof or commercial solar electricity producers. Solar energy, unlike fossil fuels, does not place excess heat or carbon into the atmosphere. The goal is to provide an incentive to produce more solar electricity globally by rewarding the generators of solar electricity. SolarCoin is intended to shift the cost of electricity, thereby reducing the payback time of a solar Installation. In working closely with the solar industry, the SolarCoin Foundation, with SolarCoin, is at the base of a virtuous circle, creating an uptake for solar equipment and helping create jobs in the Renewable Energy sector. Each SolarCoin in circulation represents 1 Mwh of solar electricity generation.”

“Network security from hashing is good. Making money is great. Curing Cancer, Alzheimer’s, Huntington’s, preventing viruses, and designing next-level pharmaceuticals is awesome. What if we could put these together, to build a coin secured and run by crypto, mined with SHA256, and supported by cancer-curing research?

Announcing Curecoin

What benefits does it provide?

Most currencies are either in the CPU/GPU stage, or in the ASIC stage. Curecoin can be earned with both. Folders use high-end GPUs and CPUs to fold proteins, earning a proportional amount of coins set-aside for their contributions. Miners mine with SHA256 ASICs as usual, securing the blockchain for the Curecoin network. Whether you are heavily-invested in ASIC equipment or still have GPUs and CPUs, you can participate. Due to the nature of folding (diverse, constantly changing, not easily predictable), GPUs and CPUs will both always be relevant, so an investment in consumer hardware isn’t wasted.”

Boid is currently in Alpha, but already putting thousands of devices to work on cancer research. This mineable EOS token incentivizes distributed scientific computing and makes it fun by incorporating teams, competitions, and prizes. Get started at: https://app.boid.com/

The Nori token is currently under development and is seeking investors. This token will be used to create a CO2 removal marketplace with the goal of helping drawdown atmospheric carbon dioxide concentrations to prevent catastrophic climate change.

Update: Nori has launched and is now helping pull CO2 out of the atmosphere and into agricultural soils!

“Nori is the world’s only carbon dioxide removal marketplace. We are building a transparent and secure platform that will allow anyone in the world to pay to remove excess carbon dioxide from the atmosphere. Our voluntary marketplace will enable carbon removal suppliers to connect directly with buyers, improving efficiency and reducing costs”.
