At 08:40 UTC on 22 October 2026, the Bitcoin network added block 972,593. By then about 20.10 million of the 21 million bitcoin that will ever exist had been issued. In the same hour Ethereum was producing a block every 12 seconds, secured by roughly 819,000 active validators. Both networks rest on the same technology, and they do very different jobs.
That is the short answer to the bitcoin vs Ethereum vs blockchain question. Bitcoin is a money: a network built for one asset that people send to each other. Ethereum is a platform: a network that runs programs, with its own coin, ether, to pay for the computing. Blockchain is neither. It is the record-keeping method under both, and it also runs inside banks and exchanges with no public coin at all.
Headlines mix the three words all the time, and some companies have made money, or lost it, on that confusion. Sorting them into three levels is enough to read most crypto news correctly. This lesson follows our lesson on how to read crypto news without being misled and assumes you know the basics covered in what a blockchain is. Figures are dated 22 October 2026. Nothing here is investment advice.
Three words, three levels: a money, a platform and a technology
Start with how each project describes itself. The Bitcoin white paper, published on 31 October 2008 under the name Satoshi Nakamoto, is titled “Bitcoin: A Peer-to-Peer Electronic Cash System”. Its first sentence talks about payments, not about databases: “A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another”.
The word “blockchain” never appears in that nine-page paper. Nakamoto writes about a “chain of blocks” and a chain of hash-based proof of work. The single noun came later, once people needed a name for the structure itself, apart from the coin.
Ethereum, launched on 30 July 2015, puts itself in a different box. Its official site calls it “a decentralized blockchain network and software development platform, powered by the cryptocurrency ether (ETH)”, and sums up the contrast with Bitcoin in two short sentences: “Bitcoin is a tool for sending value. Ethereum is a platform for building it.”
The technology level has a neutral definition from the US National Institute of Standards and Technology. In its 2018 overview (NIST IR 8202), blockchains are “tamper evident and tamper resistant digital ledgers implemented in a distributed fashion”, usually without a central authority. Nothing in that definition requires a coin, a price or a public network.
Put together, the picture has three floors:
- At the bottom sits the technology: a way to keep a shared record in blocks, each one carrying a fingerprint (a hash) of the one before, so that changing an old entry breaks every link after it.
- On top of it, Bitcoin uses that method for a single job: keeping track of who owns which bitcoin, with a supply fixed in advance.
- Next to Bitcoin, not above it, Ethereum uses the same method to keep track of balances and of the state of programs that anyone can deploy.
- Thousands of other projects sit at one of these levels, and some sit at two at once, as the examples further down show.
A useful habit for the capital letters: “Bitcoin” and “Ethereum” usually name the networks and their software, while “bitcoin” (BTC) and “ether” (ETH) name the coins. Ether is the asset; Ethereum is the network. Many outlets do not follow the rule, which adds to the muddle.
Bitcoin: one job, done on purpose with few tools
Bitcoin keeps a ledger of coins and nothing else of note. Every ten minutes or so on average, a miner wins the right to add a block of transactions by spending electricity on proof of work. On 22 October 2026, Blockchair data showed 150 blocks in the previous 24 hours, or one every 9.6 minutes, close to the target that the bitcoin.org FAQ describes as roughly every 10 minutes.
The rules on supply are written into the software. New coins come only as the block reward, which halves every 210,000 blocks; since the last halving on 20 April 2024 it stands at 3.125 BTC per block, or 468.75 BTC a day. The total will never pass 21 million. As of 22 October 2026, about 95.7% has been mined and roughly 898,000 bitcoin remain to be issued over the coming century. Each coin divides into 100 million units called satoshis.
What Bitcoin can do, then, is short and deliberate. It lets anyone with an internet connection hold and send an asset that no bank, company or government issues, on a ledger that has run since January 2009. Its fees are usually small: over the 24 hours to 22 October 2026 the median transaction paid about $0.016 and the average about $0.31 (the average is pulled up by a few large payments), across 710,519 transactions.
What it cannot do is just as deliberate. Bitcoin transactions are locked and unlocked by a small language called Script, which the developer documentation describes as “deliberately designed to be stateless and not Turing complete”. There are no loops, so a script cannot run for ever and cannot keep a memory between transactions. That rules out the kind of open-ended applications that run on Ethereum, such as lending markets or automated exchanges, directly on the base chain.
Bitcoin is also not fast at the base layer. A block every ten minutes and limited space mean that a payment is usually considered settled only after several confirmations, which can take most of an hour. Faster payments rely on systems built on top, which a later lesson on layer 1 and layer 2 covers.
Some Bitcoin “DeFi” does exist, but it mostly works through wrapped bitcoin on other chains or through side systems. DefiLlama counted about $4.4 billion locked in Bitcoin-related applications on 22 October 2026, against $49.9 billion on Ethereum. That gap measures design choices, not quality: Bitcoin was not built to host applications.
For the full story of how the network works, see our beginner guide to Bitcoin.
Ethereum: a shared computer that charges for every step
Ethereum keeps a ledger too, but each entry can hold code. A smart contract is a program stored on the chain that runs exactly as written when someone calls it: a token, a loan market, an auction, a vote. The programs run in the Ethereum Virtual Machine (EVM), which ethereum.org describes as a decentralized virtual environment that executes code consistently and securely across all Ethereum nodes.
Every step of that code costs a fee measured in gas, paid in ether. Gas exists so that nobody can clog the shared computer with an endless loop: a program that runs out of gas stops. On 22 October 2026 the base fee was about 0.19 gwei (billionths of an ether), a block could hold up to 60 million gas, and the average transaction cost about $0.19 over 24 hours, according to Blockchair. Those gas fees rise sharply when demand spikes.
Since the Merge of 15 September 2022, Ethereum no longer uses mining. Blocks are proposed by validators who lock 32 ETH each as a deposit and can lose part of it if they cheat. The switch to proof of stake cut the network’s energy use by about 99.95%, according to ethereum.org. Time is divided into 12-second slots; on 22 October 2026 the chain produced 7,183 blocks in 24 hours, almost exactly one per slot, and the beacon chain counted about 819,000 active validators. One operator can run many validators, so that number is not a count of people or firms.
Supply works differently too. Ether has no hard cap. New ether is issued to validators, and since the London upgrade of August 2021 part of every fee is burned, so the total can rise or fall depending on activity. As of 22 October 2026 about 122.15 million ETH existed, by the count of ultrasound.money. Ethereum’s own site puts it this way: Bitcoin has a fixed supply, Ethereum a dynamic one.
What Ethereum cannot do is worth knowing before reading any headline about it. Its base layer handles far fewer transactions than a card network, which is why most activity is moving to rollups built on top (the subject of a later lesson). A smart contract cannot see the outside world: it needs an oracle to learn a price or a match score. And code does exactly what it says, bugs included. A flawed contract can be drained in minutes, and the network will not reverse it. The one time a large rescue happened, after the DAO hack of 2016, it split the community and left a second chain, Ethereum Classic.
Ether is also money-like. People hold it, send it and lend it, and it has its own exchange-traded funds in the United States. So Ethereum straddles two levels: a platform first, with a coin that also behaves as an asset. Our full guide to Ethereum goes further into the network’s history and upgrades.
Blockchain: the method, which also lives outside crypto
Strip away the coins and a blockchain is a data structure plus a set of rules for who may add to it. Records are grouped into blocks; each block includes the hash of the previous one; copies sit on many computers; and a consensus method decides which new block everyone accepts. Public networks such as Bitcoin and Ethereum let anyone join and use coins to reward the people who secure them. Private, or permissioned, ledgers let only known members join, and usually have no public coin.
Those private ledgers are real and some are in production. Hyperledger Fabric, now under the Linux Foundation’s LF Decentralized Trust, describes itself as an enterprise-grade distributed ledger platform for permissioned networks; nothing on that page requires a cryptocurrency. R3’s Corda shares data only between the parties to a deal and uses a notary to block double spends. JPMorgan runs its own blockchain platform, launched as JPM Coin in 2019, later called Onyx and renamed Kinexys in November 2024; it processed about $2 billion of transactions a day at the time, according to Decrypt.
So the answer to “can you have a blockchain without Bitcoin?” is plainly yes. The answer to “do you need a blockchain?” is often no. If one company controls the data and everyone trusts it, an ordinary database is faster, cheaper and easier to correct. A shared ledger earns its cost when several parties who do not fully trust each other must keep the same record and none of them should hold the pen alone. Our guide to public vs private blockchains goes through that trade-off case by case.
Note the words NIST chose: tamper evident and tamper resistant. A blockchain makes changes to past records hard and visible. It does not make them impossible, and it does nothing to check that what was written in the first place was true. The next lesson looks at those limits in detail.
Why the press mixes them up: from the banks’ blockchain buzzword to Long Blockchain
The split between the coin and the technology was a selling point long before it was an analysis. In June 2015, Marcus Swanepoel, then chief executive of the exchange BitX, told Global Finance that many banks used “the buzzword ‘blockchain'” and said they were “interested in the blockchain but not necessarily in Bitcoin”. In plain terms, banks wanted the shared ledger without the public coin that came with it.
Swanepoel did not agree with them. Banks that understood the technology better, he said, soon found “the two are inseparable”, and that many of their ideas could be done as well with other tools. That was true of a public network like Bitcoin, where the coin pays the people who secure the ledger. It was less true of private ledgers run by known members, which is the road many banks took in the following years.
The same split showed up in what bankers said. On 12 September 2017, JPMorgan chief executive Jamie Dimon called bitcoin a fraud at a Barclays event, Fortune reported. Seven years later his bank was running Kinexys, the blockchain platform described above. Both positions can hold at once, because they are about different levels: one is a view on an asset, the other a choice of database.
Long Island Iced Tea becomes Long Blockchain
The most famous case of the word moving markets came in December 2017. Long Island Iced Tea Corp., a drinks company, announced a “pivot” to blockchain and changed its name to Long Blockchain. Its stock jumped more than 380% intraday after the announcement, according to the SEC. At the time of the announcement, the company’s business was still drinks.
On 9 July 2021 the SEC charged three people, Eric Watson, Oliver Barret-Lindsay and Gannon Giguiere, with insider trading ahead of that announcement. The agency said Giguiere bought 35,000 shares and sold them within two hours of the news for profits of more than $160,000. The action targeted those individuals, not the company.
TradeLens and ASX: the technology was not the hard part
Corporate blockchains failed more quietly. TradeLens, a shipping data platform built by Maersk and IBM, was announced to close on 29 November 2022. Rotem Hershko of Maersk said “TradeLens has not reached the level of commercial viability necessary to continue work”, adding that full global industry collaboration had not been achieved. The platform was to go fully offline by the end of the first quarter of 2023.
Two weeks earlier, on 16 November 2022, the Australian Securities Exchange cancelled its project to replace CHESS, its clearing and settlement system, with a ledger built by Digital Asset. ASX, which had picked Digital Asset in 2017, booked a pre-tax charge of A$245 million to A$255 million (about $165 million to $172 million at the time). Its chairman, Damian Roche, cited “significant technology, governance and delivery challenges”, The Block reported.
Neither case proves that blockchains do not work. Both show that a shared ledger is only useful when the people who must share it agree to do so, and that is a business problem first. When a headline says a company is “using blockchain”, the questions worth asking are which chain, who runs the nodes, and what would change if the same data sat in a normal database.
More examples at each level, and the blurry cases
Bitcoin and Ethereum are the best-known names on their floors, not the only ones. A few others show what changes from one design to the next.
Other money networks
Litecoin, launched in 2011 from Bitcoin’s code, keeps the same model with a block about every 2.5 minutes and a maximum of 84 million coins, both values set in the Litecoin Core source code. About 77.74 million LTC existed on 22 October 2026, per Blockchair.
Monero goes after a different goal: privacy. Its project site says the sender, receiver and amount of every transaction are hidden, and that every user is anonymous by default. Its supply has no fixed end either: since May 2022 a tail emission of 0.6 XMR per block keeps paying miners.
Bitcoin Cash split from Bitcoin at block 478,558 on 1 August 2017, after a long argument over whether to keep blocks small or scale on-chain with bigger ones. It shows that a money network can fork: the same history up to a point, then two chains with two coins.
Other platforms
Solana and Cardano compete with Ethereum as smart contract platforms. Solana’s documentation explains that it stores all state in accounts and calls its smart contracts “programs”. Cardano’s documentation describes it as a proof-of-stake platform and home to the ada cryptocurrency. On DefiLlama, staking or liquidity, measured at current market prices. It is the main size metric in DeFi.">value locked in applications stood at about $5.95 billion on Solana and about $62 million on Cardano on 22 October 2026, against $49.9 billion on Ethereum.
The technology without a public coin
Hyperledger Fabric and Corda, described above, are the standard examples of permissioned ledgers. The Canton Network, built by Digital Asset, is a disputed case: its makers present it as an open, privacy-enabled network, while critics argue it works as a permissioned system.
Cases that sit on two levels
Ether is a platform’s fuel and a tradable asset at once. Stablecoins such as USDT and USDC are money-like tokens that live on platforms, mostly Ethereum and Tron, which is why our guides on coins versus tokens and stablecoins treat them apart from the networks they use. Bitcoin, for its part, has a little programmability through Script, enough for multi-signature wallets and time locks but not for applications.
| Example | Level | What differs from Bitcoin or Ethereum |
|---|---|---|
| Litecoin | Money | Bitcoin’s code, 2.5-minute blocks, 84 million cap |
| Monero | Money | Private by default, tail emission, no fixed cap |
| Bitcoin Cash | Money | A 2017 fork of Bitcoin with larger blocks |
| Solana | Platform | Different account model, programs instead of EVM contracts |
| Cardano | Platform | Proof-of-stake platform with its own coin, ada |
| Hyperledger Fabric | Technology | Permissioned, no public coin required |
| Corda | Technology | Shares data only between the parties to a deal |
Bitcoin vs Ethereum side by side on 22 October 2026
The figures below come from public data pulled on 22 October 2026 between about 08:40 and 08:55 UTC (Blockchair, a public Ethereum node and beacon API, ultrasound.money and DefiLlama). Prices and market values move every minute; they are here to show scale, not as a guide to value. The third column is the point of the lesson: a method has no block height and no price.
| Bitcoin | Ethereum | Blockchain (the method) | |
|---|---|---|---|
| Level | Money network | Platform network | Technology |
| Started | January 2009 | 30 July 2015 | No single launch date |
| Main job of the chain | Record who owns bitcoin | Record balances and run smart contracts | Keep a shared, tamper-evident record |
| Consensus | Proof of work | Proof of stake since 15 September 2022 | Any rule the members choose |
| Block pace | Target about 10 minutes; 150 blocks in 24 h | 12-second slots; 7,183 blocks in 24 h | Depends on the design |
| Supply | 21 million cap; 20.10 million issued | No hard cap; about 122.15 million ETH | No coin required |
| Programs | Script, not Turing complete | EVM smart contracts | Depends on the design |
| Security | Hashrate about 1.05 zettahash/s | About 819,000 active validators | Depends on who runs the nodes |
| Average fee, 24 h | About $0.31 | About $0.19 | None for the method itself |
| Market value | About $1.646 trillion (08:49 UTC) | About $294.1 billion (08:52 UTC) | Not applicable |
| Value locked in DeFi apps | About $4.4 billion, mostly wrapped or side systems | About $49.9 billion | Not applicable |
Bitcoin traded near $81,880 at 08:49 UTC and ether near $2,407 at 08:52 UTC, according to Blockchair. At the same times, Bitcoin’s share of total crypto market value was about 57.8% and Ethereum’s about 10.3%. None of these numbers settles the bitcoin vs Ethereum argument that fills social media: they measure different things on networks built for different jobs.
How regulators treat each level
Regulators do not license “the blockchain”. They look at assets, at the firms that issue or trade them and at the products sold to the public. That matches the three levels well.
United States: SEC, CFTC and IRS
The CFTC set the tone on 17 September 2015, when it found for the first time that “Bitcoin and other virtual currencies are properly defined as commodities”. That made bitcoin a commodity under US derivatives law. On 10 January 2024 the SEC approved the first spot bitcoin exchange-traded products. Then-chair Gary Gensler stressed that the move was limited to products holding “one non-security commodity, bitcoin”, and added: “we did not approve or endorse bitcoin”.
Ether followed. On 23 May 2024 the SEC approved the stock exchanges’ rule changes (the “19b-4” filings) for eight spot ether funds, the law firm Mayer Brown noted, adding that at launch the funds would not be able to stake the ether they bought. Trading began on 23 July 2024, with nine funds from eight issuers, as The Block reported on launch day.
On 17 March 2026 the SEC published an interpretation, which the CFTC joined, that sorts crypto-assets into five groups: digital commodities, digital collectibles, digital tools, stablecoins and digital securities. Only the last group is treated as securities. The release itself (No. 33-11412) lists bitcoin and ether among its examples of digital commodities, next to Litecoin, Bitcoin Cash, Cardano and Solana. It uses “commodity” in an economic sense, and it adds that selling a non-security asset through an investment contract does not turn the asset itself into a security.
Congress has not settled the question in law. On 15 September 2026 the Senate fell short of the 60 votes needed to take up the CLARITY Act, by 49 to 50, The Defiant reported. Our report on US crypto rules after the CLARITY Act vote follows what the agencies did next.
For tax, the IRS does not distinguish between the two coins. Under Notice 2014-21, “For federal tax purposes, virtual currency is treated as property”, so selling or spending bitcoin or ether can create a capital gain or loss in dollars.
European Union and United Kingdom
In the EU, the MiCA regulation splits crypto-assets into e-money tokens, asset-referenced tokens and everything else, which ESMA describes as “crypto-assets other than asset-referenced tokens and e-money tokens”. Bitcoin and ether are generally treated as part of that last group. What MiCA licenses is the service provider (the exchange, the broker, the custodian), not the chain. Firms operating under older national regimes could continue “until 1 July 2026 or until they are granted or refused a MiCA authorisation”, in ESMA’s words. Our guide to MiCA covers the details.
In the United Kingdom, which is outside MiCA, the FCA has applied its crypto marketing regime since 8 October 2023: a crypto promotion aimed at UK consumers must come from an authorised firm or a crypto firm registered with the FCA, be approved by an authorised firm, or fit an exemption. A bank running a private ledger for its own settlement falls under the usual rules on data, outsourcing and payments, not under crypto rules.
A quick test for the next headline
Most confusing crypto headlines become clear once you place them on one of the three floors. Four questions do most of the work:
- Which level is this about? A coin’s price is the money level, an app or token launch is usually the platform level, and a bank or supply-chain pilot is the technology level.
- Is a public network with a coin involved, or a private ledger run by known members? “Company X uses blockchain” often means the second.
- What would be different with an ordinary database? If the answer is “nothing much”, the word blockchain is doing marketing work.
- Who is the regulator here? An asset, a service provider or a fund each answers to someone different.
Apply it to two examples. “JPMorgan settles payments on blockchain” sits on the technology floor and says nothing about the price of bitcoin. “Ethereum fees fall after an upgrade” sits on the platform floor and concerns people who use applications on that network. Neither headline is a reason to buy or sell anything.
The next lesson takes the technology floor apart. It looks at the three properties people usually credit to blockchains, decentralisation, transparency and immutability, and at where each one holds and where it breaks: what makes a blockchain different from an ordinary database.
