45 Blockchain Statistics That Will Make You Think | Fortunly (2022)

Blockchain as we know it today was invented by an individual or a group of people using the pseudonym Satoshi Nakamoto.

(Investopedia, Bitcoin.org, The Economist)

Blockchain serves as the public transaction ledger for the first and best-known cryptocurrency, Bitcoin. Satoshi conceived a peer-verified electronic cash that would allow monetary transactions to be performed directly between two parties without the need for intermediaries such as banks.

The blockchain itself is actually a list of records, or blocks, which are connected in series cryptographically. Each block contains transaction data (like date, time, and amount) as well as the cryptographically secured unique electronic address of the parties to each transaction. Every block also stores a code called a “hash” that uniquely identifies it. Every user of Bitcoin’s blockchain has a copy of an entire transaction history. The fact of the transaction is public and unalterable due to hashes that link each block in the chain to the previous and next blocks. The nature of the transaction and the parties to it are private.

When two people engage in a transaction, every computer belonging to the blockchain network has to verify it by solving a complex mathematical problem. Only once the verification is complete is the transaction block added to the chain. This is one reason blockchain eliminates the need for an intermediary when performing monetary transactions.

Serving as the foundation for an electronic currency is just one application of blockchain technology. Blockchains can also store medical records, contracts, or even voting results, all of which are automatically verified by the network.

The first mention of the word blockchain occurred at BitcoinTalk, the world's largest forum dedicated to Bitcoin.


According to early Bitcoin developers, the term blockchain was not used initially. Satoshi Nakamoto, the inventor(s) of Bitcoin, referred to the technology as a "proof-of-work" chain.

BitcoinTalk forum users came up with the word during a discussion about how much time it takes to download Bitcoin's "blockchain," referring to the entire history of Bitcoin transactions.

Blockchain Market Statistics

The financial sector currently accounts for more than 60% of blockchain’s worldwide market value.


The technology has spread to other sectors as well: manufacturing (17.6% of the market share), distribution and services (14.6%), public sector (4.2%), and infrastructure (3.1%). Nearly every industry has adopted blockchain tech to some extent.

By the end of 2018, about 90% of U.S. and European banks and financial institutions had begun exploring the adoption of blockchain technology.

(Law Technology Today, BlockTelegraph)

The financial sector leads the way in terms of investments in blockchain technology. During 2018, financial institutions spent about $552 million on blockchain-powered projects.

The costs of transactions using blockchain are millions of times cheaper than transaction costs in the traditional economy.

(Etherscan, Reddit)

For example, the transaction fee for transferring 849,999.99939168 Ether (which is equal to $1,129,879,499.19) is only $0.19.

Blockchain could reduce investment banks’ infrastructure costs by 30%.

(Accenture Consulting)

According to a survey of eight banks by Accenture Consulting, the potential savings on a cost base of $30 billion are more than $8 billion.

By the end of 2024, it is expected that the blockchain market will grow to $20 billion in annual revenues.

(Grand View Research, Transparency Market Research)

And when it comes to blockchain technology market size, a recent report suggests that it will reach $7.59 billion by 2024. That’s a compound annual growth rate of 37.4%. Such rapid market growth is explained by an increasing demand for this technology across all industries, from financial services, through consumer and industrial goods, all the way to media, telecom, transport, healthcare, and public services.

86% of tech-savvy executive teams surveyed by Deloitte said they believe there’s huge business potential in blockchain technology.


An even higher number (88%) of business leaders responded that this technology is scalable and that it will eventually become mainstream. Survey author Linda Pawczuk argues that Blockchain is "a versatile technology that can record financial transactions, store medical records, or even track the flow of goods, information, and payments through a supply chain."

24% of companies participating in the Deloitte blockchain survey said they would invest from $5 million to less than $10 million in blockchain technology during 2021.


Another 24% of the 1,000 surveyed companies reported that they plan to invest from $500,000 to less than $1 million, while 12% plan to spend $10 million or more.

An increasing number of food companies and retailers are experimenting with blockchain technology.

(Wall Street Journal, Reuters)

Walmart has partnered with Nestle, Dole, Unilever, and Tyson Foods to implement blockchain in the food industry. Statistics show that blockchain implementation could generate $700 million in increased productivity. In one pilot project, blockchain made it possible to trace individual mangoes back to the farm in 2.2 seconds. Walmart says that without blockchain it would take more than six days to identify the original farm.

A European retailer, Carrefour, is the first company on the continent to introduce blockchain for food products. The company believes that the technology will revolutionize its supply chains, helping raise $5 billion in organic food sales by 2022.

Every time a user uploads articles or posts comments, he or she is rewarded with the network’s native token. At the time of writing, the Steem value is $0.1818, and it’s ranked 164th on CoinMarketCap.

There are more than 63,000,000 blockchain wallet users as of December 2020.

(Blockchain.com, Investopedia)

A blockchain wallet is a digital wallet that allows users to receive, store, and spend digital currencies. A typical blockchain wallet interface shows the current balance for stored cryptocurrencies and displays the history of transactions. Blockchain wallet users can send a request to other parties for a specific amount of BTC, ETH, XRP, Litecoin, Tether, or other digital currencies.

A unique address is generated for each request. Users can send funds to other unique addresses using their e-wallets too. E-wallets can be stored online or offline; the latter method is much safer.

When a user initiates a first-ever crypto-transaction, a digital wallet generates the private key, which then generates the public key. Both are represented as strings of alphanumeric characters. The unique address to which the transactions are sent is actually a hashed version of the public key. The private key is known only by the wallet’s owner, and it allows access to cryptocurrency. Users are not able to access and withdraw the funds deposited at their addresses - that is, in their e-wallets - until they provide a unique private key.

Around 15% of IT professionals have invested in cryptocurrency, which makes them the largest group of investors.


Students, the unemployed, and retirees also constitute a significant portion of crypto investors. More than 80% of cryptocurrency investors are novices; only 7.38% say they had previous experience in investing.

Blockchain investment was up by 280% in the first three quarters of 2018 when compared to the whole of 2017.


According to one report, blockchain and crypto startups raised $3.9 billion through venture capital investments before the beginning of Q4 2018. The average size of blockchain investments has increased by more than $1 million during 2018.

According to blockchain predictions by Brock Pierce, an American entrepreneur with rich experience in digital currencies, the future of blockchain growth will be pushed by DApps, STOs, and the gaming industry.


Pierce, the co-founder of the EOS cryptocurrency platform, says that significant decentralized apps will hit millions of users in the near future. Another significant aspect of further blockchain growth will be security token offerings, which work in a more regulated manner than ICOs. The former EOS blockchain chief strategy officer predicts the tokenization of fiat money, the debt market, real estate, equities, and even art is just around the corner. The gaming industry will be a major driver of blockchain adoption as well since gamers were among the earliest crypto adopters.

Chinese manufacturer Lenovo introduced a mobile device that features “Z-space”, a blockchain-based payment system. HTC has also launched its own blockchain-focused phone.

(Asia Times, CNBC, Statista)

It seems that mobile blockchain is on its way. Statistics show that the number of mobile phone users will hit 7 billion in 2021, which is a huge, attractive market for blockchain innovators.

Key issues that need to be solved before blockchain becomes a mainstream technology are performance speed, interoperability, costs, regulations, and collaboration.

(CNBC, Deloitte, ICOService)

Issue #1: In numerous blockchain usage scenarios, performance issues must be addressed before widespread application deployment. While traditional systems are able to process thousands of transactions per second, the BTC blockchain can handle up to seven transactions per second. The Ethereum network is able to process 15 per second.

Bitcoin Stats & Facts

Bitcoin’s blockchain electricity consumption generates carbon emissions comparable to the levels produced by Kansas City or countries like Jordan or Sri Lanka.


Bitcoin miners generate annual emissions of carbon dioxide of between 22 and 22.9 megatons, according to a Technical University of Munich study published in the journal Joule. The study suggests that carbon dioxide emissions would be twice as high if other cryptocurrencies were taken into account.

The highest-ever price for a single Bitcoin by January 2021: $41,940.

(CoinDesk, CNBC)

BTC prices reached an all-time high on January 8, 2021. The world’s best-known cryptocurrency gained value for the first time in October 2009, when 5,050 BTC were sold for a little more than $5. The current Bitcoin price is about $33,529.

If you’re doing your own Bitcoin research, you may have come across the term sats crypto. Sats is short for Satoshis, the smallest unit of BTC. One Satoshi equals 0.00000001 BTC or one hundred millionth of a Bitcoin. Remember, Bitcoin current value readings are transient. The currency’s value can change in a matter of hours.

At the moment of writing, the global Bitcoin hash rate was 150,096,000 TH/s.

(Blockchain.com, Bitcoin.org, Techopedia)

A hash rate is defined as the number of hash operations in a given time period. It’s a useful measure for the processing power of blockchain networks. For example, when the blockchain network reaches a hash rate of 10 TH/s, it means that it makes 10 trillion calculations per second.

The current size of Bitcoin blockchain is 324 gigabytes.


The Bitcoin blockchain expands to hold all blocks and transactions. The average transaction size in February 2021 was 343 bytes.

The maximum number of Bitcoins that can be mined is 21 million.

(CoinSutra, Blockchain.com, IT Pro)

According to Bitcoin.com blockchain predictions, the last BTC will be mined in the year 2140. Almost 18 million Bitcoins have been mined so far.

What is cryptocurrency mining? We’re glad you asked.

Every time new BTC blockchain or other crypto transactions are made, they must be added to the blockchain. A miner is rewarded with a small amount of cryptocurrency for carrying out two tasks: validating transactions and guessing a unique 64-digit hexadecimal code (hash). For this purpose, powerful graphic cards manufactured by Nvidia or AMD are used. This time-consuming method may cost you more on your electric bill than you earn in cryptocurrency.

However, there are easier ways to get your share of digital currencies. Crypto enthusiasts use digital currency exchanges to buy crypto coins for fiat money or to trade them for another altcoin. Since cryptocurrency values are highly volatile, using forecast and prognosis tools (such as Wallet Investor predictions, for example) is a good approach.

Examples of the world’s most trusted cryptocurrency exchanges include Binance, Bitmex, CEX, KuCoin, Bittrex, Kraken, and CoinMama.

More Bitcoin mining stats: In 2020, 65% of BTC mining pools were located in China.

(University of Cambridge, Statista)

A mining pool is created when cryptocurrency miners combine their computer resources over a network. Each member of the mining pool receives a reward - a share of the mined cryptocurrency - according to their contribution in finding another block.

The Asia-Pacific region has the largest percentage of Litecoin mining pools (52%). You can find the latest news and useful information about the Litecoin market on Reddit.

7% of BTC mining pools are located in the United States. When it comes to mining statistics for other cryptocurrencies, 21% of Ethereum, 37% of ZCash, 34% of Monero, and 28% of LTC mining pools are located in North America. Most Ethereum mining pools are located in Europe (49%).

The first Bitcoin transaction occurred in 2010 when two pizzas were bought for 10.000 BTC.

(Yahoo News)

On May 17, 2010, Laszlo Hanyecz bought two Papa John’s pizzas for 10,000 BTC. If we take into account how much bitcoin is worth today, it would mean that Laszlo (aka Bitcoin Pizza Guy) paid about $332,000,000 for the meal. Plus tip, presumably.

The day of the transaction is known as Bitcoin Pizza Day among blockchain and crypto enthusiasts.

Alt Coin Stats & Facts

Alt Coin or Altcoin - A common term for cryptocurrencies other than Bitcoin. (WhatIs.com)

The current Ethereum (ETH) market cap is $149,123,341,483.

(CoinMarketCap, Blockgeeks)

ETH is the second-largest cryptocurrency by market capitalization. In terms of crypto, market capitalization (crypto market cap) is defined as the circulating supply of tokens or coins multiplied by the current price. Ethereum’s creator is Vitalik Buterin, a Canadian programmer of Russian origin who entered the cryptocurrency world by writing blogs about Bitcoin.

What makes the Ethereum blockchain different from Bitcoin’s is that it allows developers to create decentralized applications (DApps) and smart contracts. Smart contracts are computer programs that facilitate the exchange of money, property, shares, content, or anything of value between two parties without the need for an authority (a lawyer, for example).
