The world is waking up to the impressive capabilities of the blockchain.
As a foundational technology that things can be “built on top” of, the potential applications of the blockchain go way beyond just payments or cryptocurrencies. In fact, the blockchain could revolutionize how we interact with intellectual property, capital markets, insurance, healthcare, government, and many other sectors.
Introducing Smart Contracts
In particular, an exciting enabler of blockchain technology is the concept of self-executing “smart contracts”.
Today’s infographic comes from Etherparty, a smart contract creation tool, and it helps provide a welcoming introduction to how smart contracts work on the blockchain.
Smart contracts are going to change everything from the legal industry to the backbone of the stock market.
Here’s how these self-executing contracts actually work.
The Anatomy of a Smart Contract
Smart contracts help you exchange money, property, shares, or anything of value in a transparent, conflict-free way while avoiding the services of a middleman. Built upon the blockchain, a smart contract is usually:
- Pre-written logic in the form of computer code
- Stored and replicated on the blockchain
- Executed and run by the network of computers running the blockchain
- Can result in updates to accounts on the ledger (i.e. payment for an executed contract)
Using the Ethereum platform, smart contracts can be programmed using basic logic. On the most basic level, they can:
- Perform calculations (i.e. calculating interest)
- Store information (i.e. membership records)
- Send transactions to other accounts (i.e. payment for a good or service)
But most importantly, it is important to know that smart contracts are autonomous. They are not controlled by anyone – instead, they self-execute based on a set of instructions that two parties have agreed to (ie. the code).
Benefits of Smart Contracts
Smart contracts are appealing for a variety of reasons:
- Autonomy: There is no need to rely on third parties, which could be biased or not have your interests at heart.
- Trust: Your documents are encrypted on a shared ledger, and all parties can have access to them.
- Redundancy: Documents are duplicated many times over on the blockchain, and can’t ever be “lost”.
- Safety: Documents are encrypted, making them near-impenetrable by hackers.
- Speed: These contracts automatically self-execute, saving you precious time.
- Savings: Smart contracts save you money by taking out the middleman.
- Precision: Smart contracts execute the exact code provided, ensuring zero errors.
- Transparency: For organizations like governments, they could add another level of transparency to dealings.
The blockchain is already a disruptive technology, and with these benefits – the potential behind smart contracts is another facet to be excited about.
Companies Going Public in 2021: Visualizing IPO Valuations
Tracking the companies that have gone public in 2021 so far, their valuation, and how they did it.
Companies Going Public in 2021: Visualizing Valuations
The beginning of the year has been a productive one for global markets, and companies going public in 2021 have benefited.
From much-hyped tech initial public offerings (IPOs) to food and healthcare services, many companies with already large followings have gone public this year. Some were supposed to go public in 2020 but got delayed due to the pandemic, and others saw the opportunity to take advantage of a strong current market.
This graphic measures 47 companies that have gone public just past the first half of 2021 (from January to July)— including IPOs, SPACs, and Direct Listings—as well as their subsequent valuations after listing.
Who’s Gone Public in 2021 So Far?
Historically, companies that wanted to go public employed one main method above others: the initial public offering (IPO).
But companies going public today readily choose from one of three different options, depending on market situations, associated costs, and shareholder preference:
- Initial Public Offering (IPO): A private company creates new shares which are underwritten by a financial organization and sold to the public.
- Special Purpose Acquisition Company (SPAC): A separate company with no operations is created strictly to raise capital to acquire the company going public. SPACs are the fastest method of going public, and have become popular in recent years.
- Direct Listing: A private company enters a market with only existing, outstanding shares being traded and no new shares created. The cost is lower than that of an IPO, since no fees need to be paid for underwriting.
So far, the majority of companies going public in 2021 have chosen the IPO route, but some of the biggest valuations have resulted from direct listings.
|Listing Date||Company||Valuation ($B)||Listing Type|
|21-Jan-21||Hims and Hers Health||$1.6||SPAC|
|05-May-21||The Honest Company||$1.4||IPO|
|07-May-21||Blade Air Mobility||$0.83||SPAC|
Though there are many well-known names in the list, one of the biggest through lines continues to be the importance of tech.
A majority of 2021’s newly public companies have been in tech, including multiple mobile apps, websites, and online services. The two biggest IPOs so far were South Korea’s Coupang, an online marketplace valued at $60 billion after going public, and China’s ride-hailing app Didi Chuxing, the year’s largest post-IPO valuation at $73 billion.
And there were many apps and services going public through other means as well. Gaming company Roblox went public through a direct listing, earning a valuation of $30 billion, and cryptocurrency platform Coinbase has earned the year’s largest valuation so far, with an $86 billion valuation following its direct listing.
Big Companies Going Public in Late 2021
As with every year, some of the biggest companies going public are lined up for the later half.
Tech will continue to be the talk of the markets. Payment processing firm Stripe is setting up to be the year’s biggest IPO with an estimated valuation of $95 billion, and now-notorious trading platform Robinhood is looking to go public with an estimated valuation of $12 billion.
But other big players are lined up to capture hot market sentiments as well.
Electric truck startup Rivian Automotive (backed by Amazon) is estimated to earn a public valuation around $70 billion, which would make it one of the world’s largest automakers by market cap. Likewise, online grocery delivery platform InstaCart, which saw a big upswing in traction due to the pandemic, is looking at an estimated valuation of at least $39 billion.
Of course, there’s always a chance that potential public listings and offerings fall through. Whether they get delayed due to weak market conditions or cancelled at the last minute, anything can happen when it comes to public markets.
This post will be periodically updated throughout the year.
Visualizing the Power Consumption of Bitcoin Mining
Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?
Visualizing the Power Consumption of Bitcoin Mining
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.
Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.
Why Does Bitcoin Mining Require So Much Power?
When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.
Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.
These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.
Putting Bitcoin’s Power Consumption Into Perspective
On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.
|Name||Population||Annual Electricity Consumption (TWh)|
|All of the world’s data centers||-||205|
|State of New York||19.3M||161|
|Walt Disney World Resort (Florida)||-||1|
Note: A terawatt hour (TWh) is a measure of electricity that represents 1 trillion watts sustained for one hour.

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.
For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.
Where Does This Energy Come From?
In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.
Here’s how the share of cryptominers that use each energy type vary across four global regions.
|Energy Source||Asia-Pacific||Europe||Latin America|
and the Caribbean

Editor’s note: Numbers in each column are not meant to add to 100%
Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.
Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.
Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.
Towards a Greener Crypto Future
As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.
Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.
“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry
This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.
