Donating money, time, or resources to charities makes the world a better place, but what if you don’t have any of those things to spare? If you’re using the internet via a web browser maybe you can donate some spare CPU cycles though. A new site called Donate Your Tab uses your computer’s spare computational power to mine Monero (a cryptocurrency), it is then donated to a charity of your choice. The technology behind it has come under scrutiny recently because some sites are using people’s browsers to mine without their consent. Donate Your Tab allows you to opt-in to the mining and even control how much energy goes to mining.
Why would I want to use this?
We obviously think you should contribute your time, voice and cold hard cash to your favorite charity. But this site is a good start. You’re already on your computer, why not use that time to make money for causes you support? These days we often feel guilty like we can’t change anything but this allows you to do something even when you’re just sitting on the internet scrolling through your newsfeeds.
How much money can we raise on this thing?
Good question. Mining cryptocurrency isn’t profitable unless you do it over an extended period of time and have lots of people contributing.
Lets say you can make $0.05 for leaving this thing running in a browser tab all day. $0.05 x 100,000 users x 365 days = $1,825,000 to charity. Not bad! Spread the word so we can get there.
Blockchain technology stems from Bitcoin and provides a platform for change greater than Bitcoin itself. Researchers in the renewable energy industry have realized that blockchains can be used to replace outdated billing and tracking. Presently when a company produces energy it requires verification form other companies and each step eats into profits – a more efficient system would be use blockchains to verify the system by cutting out the middleman. The blockchain also provides a transparent solution that makes for easier monitoring and accountability than what’s currently provided.
The blockchain being used the example below is powered using my favourite cryptocurrency Ethereum. It is another way that distributed ledger systems mixed with computing power can alter our economies for the better.
Keeping track of renewable-energy certificates is one of dozens of potential applications of blockchain technology that could solve data management challenges in the electricity sector without disrupting business as usual, according to Morris. He and many others believe that in the long term, the technology could help transform the very architecture of the grid itself.
To unleash the potential of blockchain in the energy sector, Jesse Morris’s team at RMI has joined with Austria-based blockchain startup Grid Singularity to create a new nonprofit called the Energy Web Foundation. Earlier this month, the EWF launched its own blockchain, which Morris says is “purpose-built for the energy sector.” Based on Ethereum, the network will be a test bed for promising use cases. To validate transactions during the test, EWF will rely on 10 major energy companies that have signed on as affiliates.
Cryptocurrencies have popularized the use of a digital concept called a blockchain. These blockchains can be used to track transactions and increase accountability of shared networks. If this sounds familiar, a few months ago we looked at how blockchain technology can be used to track physical items.
Citizens around the world have been losing trust in their in governments. Certain parties are getting elected that increase corruption, or at least, make it look like those in charge are running a kleptocracy. This leaves the average person distrusting of their government, maybe using blockchain technology this trend can be reversed.
Tillemann believes blockchain could play a big role in improving trust in government, improving bureaucratic efficiency, and maintaining integrity of public data, from vote counts to land registry titles. (We discussed several other social impact applications for blockchains here).
“The critical challenge facing society right now is the breakdown in trust in institutions,” he tells Fast Company. “Blockchain was designed from the ground up to address that, creating systems that are highly secure, highly transparent and resistant to corruption.”
Blockchain technology is changing the world of commerce and law, now it can be used to track real world blocks instead of just digital blocks. The technology got attention thanks to the rise of Bitcoin, which is still going strong, and has been improved since then. More recent takes on the technology like Ethereum have evolved blockchains to be more robust, faster, and malleable for unique circumstances. A new startup, Peer Ledger, wants to use this technology to monitor ethical mining practices.
However, Ms. Jutla says there is mounting pressure from the international community to stop the unethical production of minerals, and she says Peer Ledger’s Mimosi product provides a solution to this problem. Mimosi uses a private permissioned blockchain, which chronologically and permanently logs information that’s copied across a computer network accessed by multiple collaborating parties. When a transaction is carried out, it’s grouped together in a cryptographically protected block. In the case of the Mimosi technology, every transaction involving a source of ore can be linked back to older blocks containing previous sales transactions for the ore. This allows Mimosi users to trace gold and other precious and industrial metals (mainly tin, tantalum and tungsten) from the refiner, to the processor, to the distributor.
Ms. Jutla is confident customers will want Mimosi. Not only does she think the technology will make it tougher for unethical sources of precious and industrial metals to make it into the supply chain, she says it will reduce a client’s compliance costs in this area by 75 per cent.
Hermicity is a proposed community for hermits. The inhabitants would live on their own to cater to their need for isolation, they won’t even need to go to the grocery store. Drones would be used to deliver the meal alternative Soylent to the people paying to live in the community. What’s more is that the entire operation will be based around a blockchain!
This is how it’s described on the website:
A hermit colony ran as a decentralised autonomous organisation on the ethereum blockchain.
We now have the technology to allow people to live completely alone. Drones will airlift soylent packets and water to the members of the hermit colony.
Membership is paid with ether to a smart contract. The smart contract sends drone from a solar powered docking station to the members.
In an interview this is the way the creator described his motivation:
almost every great thinker has spent much time alone. I know the time I have spent alone (admittedly somewhat forced by circumstance) has made me a wiser, more intelligent person. Perhaps by making being alone more accessible we can unlock a lot of human potential that is standing idle at the moment, locked away in bodies that are too distracted by the other bodies around them and are therefore unable to look in and unlock their unique ideas and energy.
