How Boundaries Can Help the Blockchain to Scale
The blockchain offers a long overdue upgrade for our changing economy.
However, the world isn’t quite ready for broadscale blockchain adoption. The technology is still in its relative infancy, and to reach its true potential the blockchain must be able to successfully replace existing systems while also operating at meaningful scale.
Today’s infographic comes to us from eXeBlock Technology, and it explores how good blockchain governance can help solve the pressing challenges around blockchain adoption and implementation, including the ever-present issue of scalability.
So You Say You Want A Blockchain
While it’s relatively easy to implement a blockchain in an organization, it’s far more difficult to decide just how that network should operate. For a blockchain to generate and hold any real competitive advantage, there are a few key questions to consider:
How big can you grow before sacrificing efficiency? As the blockchain grows, so do the number of nodes to process transactions. This creates a bottleneck and slows down the system.
What are your privacy needs? The attraction of the blockchain lies in its ability to decentralize information and make it transparent, but this creates a challenge for corporations who use the blockchain to handle sensitive or proprietary information.
Will your blockchain play nicely with other blockchains? There are a number of blockchain configurations – and to date, no cross-industry standards. This means your blockchain might not collaborate smoothly with another blockchain, particularly if the security standards are mismatched.
How Can Blockchain Governance Help?
Blockchain governance is concerned with solving these problems by:
- Reducing scalability obstacles by finding ways for blockchains to reach consensus faster without sacrificing decentralization
- Providing a foundation for shared standards, so organizations can collaborate without risking the privacy of their data
- Providing a framework for adaptability – a playbook for the blockchain to rely on when inevitable problems and security issues crop up
Think of governance as a constitution to help the blockchain run smoothly: it improves efficiency, encourages collaboration, and outlines a course of action when the system falters.
Types of Blockchains
There are four different types of blockchains, each with unique characteristics:
- Operates under the leadership of a group, and access is limited to only members of the group
- Due to limited membership, they are faster, can scale higher, and offer more transaction privacy
- Access might be public or restricted, but only a few users are given permission to view and verify transactions
- Ideal for database management or auditing services, where data privacy is an issue
- Compliance can be automated, as the organization has control over the code
- Open-source and available to the public
- Transactions are transparent to anyone on the network with a block viewer, but anonymous.
- The ultimate democracy – this fully distributed ledger disrupts current business models by removing the middleman
- Minimal costs involved: no need to maintain servers or system admins
- A public blockchain, which hosts a private network with restricted participation
- The private network generates blocks of hashed data stored on the public blockchain, but without sacrificing data privacy
- Flexible control over what data is kept private and what is shared on the public ledger
- Hybrid blockchains offer the benefits of decentralisation and scalability, without requiring consensus from every single node on the network
Within each of these systems, blockchain governance outlines different standards for privacy and security. Governance determines how consensus is reached, and how many nodes are required. It establishes who has access to what information, and how that data is encrypted. Governance sets up the foundations for blockchains to scale according to the needs of the organization.
Blockchain governance exists to smooth the transition to widespread adoption, providing organizations with dynamic solutions to make their blockchain suit their needs without sacrificing the security of decentralization.
A Visual Guide to Profile Picture NFTs
Feeling bored on social media? Consider investing in profile picture NFTs, one of the most popular digital assets being traded today.
A Visual Guide to Profile Picture NFTs
How do you represent yourself on social media? For most people it’s a selfie, a photo with their friends, or a picture of their pet—but what about a digitally-created character?
Profile picture NFTs are pieces of digital artwork that people use to express themselves online. Each item is a depiction of a character’s face, and has a unique mix of attributes that gives it a sense of collectability.
Like other NFTs, they’re secured on a blockchain and can be bought and sold for cryptocurrency. And while there’s nothing to stop you from screenshotting an NFT and using it for your own profile, the market for these items continues to grow.
To learn more, this infographic explains how three well-known profile picture NFT collections were created.
CryptoPunks are commonly regarded as one of the first examples of NFTs. The collection consists of 10,000 unique “punks” and was released in 2017 by Larva Labs.
One interesting fact is that these NFTs were originally given out for free—today, they are worth thousands or millions of dollars each. According to OpenSea, one of the largest NFT marketplaces, CryptoPunk #3100 was sold for 4,200 Ethereum (roughly $7.6 million) in March 2021.
A large component of #3100’s perceived value is its blue alien skin, which only eight other punks have. In other words, it’s incredibly rare. The following table shows the species distribution of the CryptoPunks collection.
Bored Ape Yacht Club
Next is the Bored Ape Yacht Club (BAYC), another collection of 10,000 unique profile picture NFTs. Unlike CryptoPunks, BAYC NFTs show both the head and torso of a character (in this case, an ape).
This opens up many combinations of clothing items, facial features, and accessories. Altogether, there are seven categories of attributes: Background color, Clothes, Earring, Eyes, Fur, Hat, and Mouth.
The following table lists some examples of BAYC attributes, and their % rarity. To explore further, visit the BAYC gallery.
|Attribute Category||Attribute Name||% Rarity|
BAYC NFTs also grant access to members-only benefits. This includes access to a collaborative graffiti board, as well as other NFTs from spin-off collections like the Bored Ape Kennel Club (BAKC). As its name suggests, the BAKC is a collection of dogs, rather than apes.
Cool Cats NFT
The last collection is Cool Cats NFT, which again amounts to 10,000 images. Cool Cats were minted at a cost of 0.06 Ethereum each, or roughly $200. The act of “minting” an NFT is similar to when metal coins are entered into circulation.
Each Cool Cat NFT is a depiction of a cartoon cat with a varying number of facial features, hats, and shirts. Altogether, there are over 300,000 possible options that could be included.
Building Your Identity in the Metaverse
A criticism of today’s social media is that there’s little room to express yourself.
Think back, for a moment, to the days of MySpace. Users could spend hours customizing their profile page, adding music, art, and whatever else they felt was an expression of themselves. As the platform’s name implied, it was a space that belonged to you.
The metaverse offers something similar. To take part in a virtual universe, you need an avatar—a digital manifestation of yourself. Avatars will be highly customizable and far less constrained by the limitations of the real world.
If you’re having trouble imagining this, check out VR Chat, a virtual reality game where players socialize as aliens, monsters, and other “interesting” beings.
This may help to explain the recent craze around profile picture NFTs. When the metaverse arrives, these NFTs could become a user’s avatar. After all, who wouldn’t want to have blue alien skin?
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.

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.
