Solar crypto currencies
Launched in , Bitcoin was the first application of blockchain or distributed ledger technologies DLTs more broadly. Since then, both Bitcoin and blockchain have matured tremendously. These new bottom-up and decentralized blockchain designs are desperately needed to overcome current legacy system thinking and path dependence to incentivize collaboration for major change and enable digital democracy for the Paris Agreement and climate action more broadly. Unfortunately, blockchain is still frequently perceived and used as a blanket term synonymous with bitcoin rather than a broad group of diverse technologies. It is like using the Internet when you really want to refer to a specific application like Facebook, Amazon, Netflix, or Google — they are all based on the same infrastructure i. Still, they have very different use cases and designs.

Accueil Volumes and Issues Special Issue 17 2. AI in the City, the Age of Pre Blockchains and the Civic Nervous In this article, Alessandro Voto takes us on a journey to explore how the rise of Blockchains protocol will transform city management enabling more distributed city governance and the emergence of a range of new urban services where machines and humans collaborate in new ways to store, move and transact. Projected to operate at a fraction of the cost of centralized protocols, those new services will be particularly adapted to underserved populations by providing mobile and secure identity for them and the value that they create.
Machines and artificial intelligence agents will be equal contributors in the smart city symphony of the future. Its inhabitants work symbiotically to turn raw materials into life-sustaining products and services for the greater whole. To move and protect the value they generate together, people depend on civic infrastructure like laws, markets and contracts. Together, these tools and their enforcers act like a city-wide nervous system, letting communities reliably respond to emerging needs and painful attacks.
In exchange, however, we gave these institutions the power to artificially limit our interactions so that they could extract profit or censor activities they deemed inappropriate.
Furthermore, they became convenient targets for data breaches and third-party manipulation. One such technology, known as a blockchain, uses these direct links as a hedge against centralized civic power. It will extend trustworthy institutional protections and financial services to marginalized and poor people worldwide. It will reinvent the way we manage physical city infrastructure and digital community structures.
What follows is a brief glimpse into the future of a blockchain-based civic nervous system. For this reason, one of the most important functions a blockchain can serve is to manage personal and organizational identity information. Worldwide, the United Nations estimates that there are 1. They can then start associating data about their activities and relationships with the identifier through subsequent transactions on blockchain. Since anyone on the network with a copy of the blockchain can access these records, urban denizens can easily find and establish ties with new collaborators according to strict and verifiable criteria, all without a central identity manager.
City schools and mentors will pass unforgeable learning badges to their students, letting students port micro-credentials to new geographies and educational venues. Organizations will have their own blockchain personas, with their civic and environmental impact audited and visible to others. Even municipal robots will have their identity tracked to ensure they are performing up to code and not deviating from their duties.
Once the coin is mined, its owner can pass it along by submitting a transaction record to miners for inclusion in the public blockchain. All of this is done without formal identity using only cryptographic addresses to hold and move funds.
By logging transactions across a massive network of pseudonymous peers instead of a central payment processor, anyone with an Internet connection can accept or send the currency without fear of censorship or rent-seeking middlemen.
The global poor and the ultra-elite alike will use these frictionless networks to access international investment opportunities and banking services never afforded to them before. City governments will have their own accounts, known in blockchain parlance as wallets. Citizens will fund government wallets with transparent tax contributions, authorize spending as a crowd, and carefully audit transaction ledgers to minimize corruption and wasteful spending.
Dogecoin, for example, was a bespoke currency that gained success from its playful branding marked by poor language translation and Shiba Inu dogs. In cities of the future, people will hold their wealth in a great number of tokens, each with their own transaction rules, backing assets, and community connections. Some will be fully fungible to encourage massive investment, while others will be limited to singular uses. Transactive Grid, Solar Coin, and the Energy Web Foundation are three projects aimed at establishing renewable energy microgrids where neighbors can pay each other for spare electrons without passing through a central energy company.
This technique, known as a payment channel, will enable micro-payments to flow between people with little to no transaction cost. This means Internet user can pay WiFi router owners for access on a per-byte basis. Polluters might pay per carbon emission. Muralists might receive donations per glance from eye-tracked onlookers. With this in mind, a blockchain real estate investment company called FOAM imagines a world where architects can propose new real estate projects like a Kickstarter campaign, then allow investors from anywhere to effortlessly gain an equity stake in their production.
Investors and other stakeholders could then vote on matters related to the project, making each city project an experiment with decision-making built directly into its structure.
This brings us to the next blockchain. They will also store bits of computer code called smart contracts to perform complex operations without relying on a single third party to execute them. No one can change the agreement, censor people from interacting with it, or prevent it from executing, unless explicitly specified in the code itself. We will see land rights, trade agreements, incorporation documents, voting systems, and more re-invented to be self-enforcing, freeing up costly labor while opening up new opportunities for collaboration that would otherwise be costly to arrange.
Civic designers will be tasked with designing these unstoppable systems with an eye to human needs, preventing blockchain uses that reinforce old models of injustice.

Candriam questions whether proof-of-stake protocols, renewable power and action by regulators might drive the future greening of digital assets. By Jamie Gordon ,. The ESG credentials of cryptocurrencies took a hit following a series of damning headlines earlier this year, however, there may be light at the end of the tunnel for budding, ethical crypto investors, according to a recent report from Candriam. For instance, citing research by the University of Cambridge, the report noted bitcoin uses around 0. In practical terms, this consumption is enough to run all kettles in the UK at their current level of usage for 29 years — but the problem is not how much energy bitcoin uses now, rather what it will use going forwards. Not only do frothier valuations and greater familiarity with digital assets attract yet more speculative participants, but the persistence of larger cap currencies also mean they are being used either tactically or strategically by large financial institutions.

Cryptocurrencies can enable financial inclusion. Will you participate?
A worker is seen next to a container, where a Bitcoin mining facility is installed, at the Berlin geothermal plant of La Geo electrical company, where the Salvadoran government installed a Bitcoin mining facility for the use of bitcoin as legal tender, in Alegria, El Salvador, October 15, Energy-intensive cryptocurrency "mining" is done by computers, and has come under criticism from environmentalists as a big source of demand for mostly fossil fuel derived electricity. Last month, El Salvador became the first country to adopt bitcoin as legal tender alongside the U. Daniel Alvarez, president of the state-run Lempa River Hydroelectric Executive Commission CEL , said El Salvador has the potential to generate electricity through hydroelectric, solar, wind and tidal power projects. The Salvadoran government in September began harnessing geothermal energy for bitcoin mining from a plant at the base of the Tecapa volcano, kilometers 66 miles east of the capital, that is owned by a company which is part of CEL.

Connecting decision makers to a dynamic network of information, people and ideas, Bloomberg quickly and accurately delivers business and financial information, news and insight around the world. The site made sense for running servers 24 hours a day because it has access to low-cost electricity generated by water flowing from the nearby Caucasus Mountains. There also are plans for solar panels and wind turbines. Renewable energy is becoming the preferred way of mining digital currencies like Bitcoin as prices surge and the industry seeks more computing power. While traditional fuels like coal remain staples for many utility grids, big miners including Bitmain Technologies Ltd.
Renewable Energy Offsets the Carbon Footprint of Cryptocurrencies
He did not indicate what had brought him to that realisation, which comes after a period of heavily promoting a variety of cryptocurrencies. But he did suggest that it would be possible to change in the future — if cryptocurrencies were to become more sustainable. In recent times, and amid growing prices and interest in cryptocurrency, alarm has been raised that the amount of energy it uses is unsustainable. And it is growing all the time, with the estimated consumption nearly three times more than it was this time last year, according to the same data. That energy use is built into bitcoin — it is not an accident but an intentional and designed part of the system.
Cryptocurrency mining is a difficult and costly activity. Miners must pay to build rigs capable of vast amounts of processing power, and then the rigs themselves must be powered with large quantities of electricity. It's all a careful balance between how much the operation costs and how much profit it is able to generate. With mining operations for Ethereum, one of the leading digital currencies on the market today, taking up the same share of electricity as that of a small country , miners have to be careful that they aren't spending more than they are making.
With more than 4, mineable coins and tokens in existence, which, if any, are the most sustainable cryptocurrencies? Are you a Dogecoin fan? This is because there are so many parameters at play. Many much smaller cryptocurrencies, for instance, naturally have a far lower energy footprint because they involve far fewer daily transactions compared to Bitcoin. Scale them up, however, and they may be just as bad, if not worse than the cryptocurrency we currently love to hate.
A nonprofit, independent media organization dedicated to telling stories of climate solutions and a just future. To say that the cryptocurrency known as Bitcoin eats a lot of energy is an understatement. In response, green-minded geeks have launched a batch of competing cryptocurrencies that take aim at the seemingly insatiable source of energy consumption that comes with Bitcoin mining, the proof-of-work system.
