Volvo Uses Blockchain To Ensure Ethical EVs

November 20th, 2019 | by Jo Borrás

Blockchain technology is (in the simplest way I can think of to describe it) a time-stamped series of transactions that are linked together, mathematically, to form a "chain." Each transaction in the chain is a "block," and they're tied together using a cryptographic algorithm (fancy math) in a way that makes it impossible for the chain to be modified


Blockchain Is Decrypting Africa’s Future In Renewables

October 25th, 2019 | by The Beam

Just a few years ago, the notion of a consumer-driven energy sector was unheard of, much less within the African context. Fast-forward to 2019, and blockchain is opening a new energy chapter, driven by smart technologies

Cleantech Blockchain Initiatives (Blockchain Report Excerpt)

December 9th, 2018 | by Michael Barnard

Blockchain clean technology solutions are spring up globally. At present we see 63 initiatives across 26 countries. Some are innovation efforts by major utilities and vendors.

The Dark Side Of Blockchain: Electricity Consumption (Blockchain Report Excerpt)

December 8th, 2018 | by Michael Barnard

The high electricity consumption of bitcoin has been widely reported, with one widely reported (and disputed) estimate having it consume at peak more electricity than 159 countries. However, this is a temporary problem with cryptocurrencies including bitcoin, not an immutable feature


Major Blockchain Technologies, Part 2 Of 2 (Blockchain Report Excerpt)

December 1st, 2018 | by Michael Barnard

It’s safe to say that cleantech is going to involve blockchain and similar distributed ledger approaches. And it’s also safe to say that each of the technologies and approaches represented here have better and worse uses. If someone tells you that the answer is only one of these, then you can be pretty sure that they are enthusiasts, not architects


Nori In Its Own Words: 6 Questions (Blockchain Report Excerpt)

November 24th, 2018 | by Michael Barnard

Nori, a company which recently emerged from stealth, is creating the Nori token. It’s a cryptocurrency token that represents a ton of CO2 removed from the atmosphere and sequestered in one of a number of potential ways. This isn’t a cap-and-trade or carbon-tax system, but a market mechanism which values removed tons of CO2. Like carbon offset programs for fliers and drivers, it allows individuals and businesses to offset their CO2 emissions with guaranteed removal of CO2 from the atmosphere

Energy Web Foundation (EWF) has great bones. It was founded by two leading organizations in the clean energy space: the influential Rocky Mountain Institute founded by Amory Lovins in 1982 and the more recently formed Grid Singularity, a blockchain- and grid-fo- cussed organization with core Ethereum blockchain developers, experienced energy executives, energy regulators and technology entrepreneurs


Smart Contract Sweet Spots: Basic Implications (Blockchain Report Excerpt)

November 10th, 2018 | by Michael Barnard

One clear area where smart contracts have potential is in cross-border purchases of finished goods or raw materials where no business relationship exists. Herstatt risk already applies due to the exchange rates with the foreign seller, although at a lower level of risk. Projecting accounts receivable into a distant country is problematic at best


The Post-Westphalian Nature Of Cryptocurrencies (Blockchain Report Excerpt)

November 4th, 2018 | by Michael Barnard

It’s worth elaborating on the post-Westphalian nature of cryptocurrencies for the purposes of this discussion. The Peace of Westphalia was a series of treaties signed in 1648 which formally ended both the 30 Years War and the 80 Years War, which were both Catholic vs Protestant wars and a war between the Roman Empire and a bunch of mostly Protestant nations


Smart Contract Business Drivers: Multiplying Parties, Default Costs, & Penalty Clauses (Blockchain Report Excerpt)

October 28th, 2018 | by Michael Barnard

One of the purported advantages of smart contracts, including a third party such as a delivery organization in a contract, is actually an added complexity. Anything which involves multiplying parties to a contract increases its complexity, as is true with any solution to a problem. One of the original English formulations of Occam’s Razor was do not multiply entities without necessity.
