An independent guide · Updated 13 October 2026

What is Cardano?

Cardano is a public blockchain, launched in 2017 and built on peer-reviewed research, where people who hold its coin, ADA, secure the network by staking and vote directly on how it is run and funded.

Cardano in 60 seconds

The short version

If you only read one part of this page, read this. Six ideas cover most of what makes Cardano what it is.

A shared public ledger

Cardano is a blockchain: a record of transactions kept by thousands of independent computers instead of one company. Nobody can quietly rewrite it.

ADA is its coin

ADA pays transaction fees, is staked to secure the network, and carries voting power. Its smallest unit, one millionth of an ADA, is called a lovelace.

Proof of stake, not mining

Blocks are produced by stake pools chosen in proportion to the ADA delegated to them, using a protocol family called Ouroboros. No energy-hungry mining is involved.

Research first

Core designs are written up as academic papers and peer reviewed before they are built. Supporters see rigour; critics see slowness. Both have a point.

Programmable

Since 2021 Cardano has run smart contracts, which power exchanges, lending, stablecoins and NFTs. Its ledger uses a model called extended UTXO.

Run by its holders

Since 2024 and 2025, protocol upgrades and treasury spending are decided by on-chain votes of ADA holders' representatives, stake pools and a constitutional committee.

Origins

Where Cardano came from

Cardano's story starts inside another project. Charles Hoskinson, an American mathematician, was one of the co-founders of Ethereum and briefly its chief executive. He left in mid-2014 after a disagreement about how the project should be organised. Jeremy Wood, who had worked on Ethereum's early operations, left around the same time.

In 2015 the two founded IOHK (Input Output Hong Kong, today called Input Output or IOG), an engineering company that builds blockchains. Their idea for Cardano was unusual for the time: rather than publishing a white paper and shipping quickly, they would treat a blockchain like safety-critical software. Protocols would be designed by academics, submitted to cryptography conferences for peer review, and implemented with formal engineering methods in the Haskell programming language.

The project was funded by a sale of ADA vouchers that ran in several tranches from 2015 to early January 2017, sold largely to buyers in Japan. According to the audit figures published on cardano.org, about 25.9 billion ADA were sold for roughly 108,844 bitcoin, worth about 62 million US dollars at the time. A further 5.2 billion ADA were created for the three founding organisations.

The network went live on 27 September 2017. In the same year the research team published Ouroboros, described by its authors as the first proof-of-stake protocol with a rigorous security proof, at the Crypto 2017 conference.

Why the names?

The platform is named after Gerolamo Cardano, a sixteenth-century Italian mathematician and physician who helped found probability theory. The coin is named after Ada Lovelace, the nineteenth-century mathematician often called the first computer programmer. The development eras are named after poets and thinkers: Byron, Shelley, Goguen, Basho and Voltaire.

Three founding organisations

From the start, responsibility was split three ways so that no single body owned the project. Input Output did the research and engineering. The Cardano Foundation, a Swiss non-profit based in Zug, was set up as an independent custodian focused on adoption, standards and oversight. Emurgo, founded in Japan, was the commercial arm, investing in and building products. Since 2024 these three no longer control the protocol: the special "genesis keys" they held were retired when on-chain governance took over.

Timeline

Five eras, 2017 to 2026

Cardano's roadmap was organised into five themed eras. They overlap in practice, but each one added a distinct capability. Select an era to explore it.

How it works

Under the hood, in plain English

Ouroboros: who makes the next block?

Time on Cardano is divided into one-second slots, grouped into epochs that last five days. For each slot, a private lottery weighted by stake decides which stake pool, if any, may produce a block. On average a block appears about every 20 seconds. Because the lottery is weighted by ADA rather than computing power, attacking the chain would mean controlling a very large share of all staked ADA.

Stake pools and delegation

Stake pools are servers run by independent operators (SPOs). Any ADA holder can delegate to a pool from their own wallet. Delegation is non-custodial and liquid: the coins never leave your wallet, are not locked, and can be spent at any time. There is no slashing, so a misbehaving pool cannot cost you your principal; it would only earn you fewer rewards.

Extended UTXO

Bitcoin tracks coins as separate "unspent outputs", like banknotes in a wallet. Ethereum tracks balances in accounts, like a bank statement. Cardano extends Bitcoin's model so each output can also carry data and be locked by a smart contract. The result is that the outcome and fee of a transaction can be checked before it is sent, at the cost of a design style many developers find less familiar.

Smart contracts and native tokens

Contracts compile to Plutus Core. Developers originally wrote them in Haskell-based Plutus; today Aiken, a purpose-built language, is widely used, alongside others. Tokens and NFTs on Cardano are "native": they are tracked by the ledger itself, just like ADA, rather than by a separate contract.

Try it: delegate and watch the epochs

A simplified simulation. The three pools are fictional and the numbers are illustrative, not real rewards.

Choose a pool, then press Delegate.

Compare: accounts versus eUTXO

Alice has 70 and sends 30 to Bob. Switch between the two bookkeeping models.

Tokenomics

ADA supply: capped at 45 billion

ADA has a hard maximum of 45 billion coins. About 31.1 billion existed at launch. The rest sits in a protocol-controlled reserve that is released gradually as staking rewards and treasury income.

25.93 billion (57.6%) sold in the 2015 to 2017 voucher sale
5.19 billion (11.5%) to the founding entities: Input Output about 2.46 billion, Emurgo about 2.07 billion, Cardano Foundation about 0.65 billion
13.89 billion (30.9%) held in reserve at launch, to be paid out over time

How much is circulating now?

Live figure unavailable until market data loads.

Where rewards come from

Every five-day epoch, the protocol takes a small fixed fraction of whatever remains in the reserve (0.3% under the parameters in force at the time of writing) and adds that epoch's transaction fees. Because it is a fraction of a shrinking pot, new issuance falls over time.

The treasury

A fifth of each epoch's pot goes to the on-chain treasury; the rest is available to stake pools and delegators. The treasury can only be spent through governance votes, described below.

No burn, no pre-set halving

Cardano has no Bitcoin-style halving events and does not burn fees. Parameters such as the expansion rate can be changed, but only by an on-chain governance vote.

Staking rewards estimator

Illustration only. You choose the rate. Real rewards vary by pool, fees, luck and total stake, change over time, and are paid in ADA whose price can fall. This is arithmetic, not a forecast or a promise.

Governance

Who decides? Three bodies, one chain

Until 2024, changes to Cardano needed signatures from keys held by the three founding organisations. A design called CIP-1694 replaced that with on-chain voting. It arrived in two steps: the Chang upgrade on 1 September 2024, and the Plomin hard fork on 29 January 2025, which gave the new system full power.

Anyone can submit a governance action by posting a refundable deposit. Three groups then vote, and different kinds of action need different combinations of approval:

DReps (delegated representatives). Every ADA holder can delegate their voting power to a DRep, become one, or choose to abstain. Voting power follows ADA, and delegating does not move or lock your coins.
Stake pool operators (SPOs). The people running the network vote on matters such as hard forks and security-critical settings.
The Constitutional Committee. A seven-seat body that checks each action against the Cardano Constitution. It rules on constitutionality, not on whether an idea is good.

The first Constitution was drafted through workshops around the world, approved by delegates at a convention held in Buenos Aires and Nairobi in December 2024, and ratified on-chain in early 2025. An updated version followed in January 2026. A community-elected committee replaced the interim one in 2025, and four of its seats were renewed by election in September 2026.

What can be voted on

Seven action types: hard forks, protocol parameter changes, treasury withdrawals, updates to the Constitutional Committee, changes to the Constitution, motions of no confidence, and non-binding "info" actions.

The treasury in practice

Treasury withdrawals need approval from roughly two thirds of active DRep stake plus the committee. A "net change limit" caps total withdrawals: the one approved in February 2026 allows up to 350 million ADA between February 2026 and early July 2027.

It really does say no

In 2026, voters approved a set of infrastructure budgets, narrowly passed the van Rossem hard fork, turned down funding for a Cardano Summit, and rejected a 12.29 million ADA request from Input Output for a Bitcoin lending product.

One practical consequence for stakers: since the Plomin hard fork, staking rewards keep accumulating as before, but you can only withdraw them once your wallet has also made a vote delegation, to a DRep or to one of the built-in "abstain" or "no confidence" options.

Stewards Midnight, a privacy-focused network that began as a Cardano partner chain. One of five bodies in the "Pentad" coordination group.

Ecosystem

What people actually do on Cardano

Cardano's application layer is real but modest in size compared with Ethereum or Solana. Here is an honest map of it.

Decentralised finance

The largest applications are decentralised exchanges such as Minswap, SundaeSwap, WingRiders and Danogo, the lending market Liqwid, and Indigo, which issues synthetic assets. Total value locked in Cardano DeFi was in the range of roughly 70 to 140 million US dollars during 2026 according to DefiLlama, a small fraction of the tens of billions on Ethereum.

Stablecoins

For years Cardano lacked a major dollar stablecoin. Smaller ones exist, including fiat-backed USDM and USDA and the crypto-backed DJED. In February 2026 USDCx, a version of Circle's USDC, went live on Cardano, funded through a 70 million ADA "critical integrations" budget that also covers oracles (Pyth), analytics (Dune) and cross-chain messaging (LayerZero).

Native tokens and NFTs

Because tokens are built into the ledger, minting them is cheap and does not require a contract. Cardano has had an active NFT and community-token scene since 2021. A programmable-token standard (CIP-113), reported live in October 2026, lets issuers add compliance rules such as transfer restrictions for regulated assets.

Real-world uses

Projects have focused on identity, credentials and supply-chain traceability, for example a student-credential programme announced with Ethiopia's Ministry of Education in 2021 and product-authenticity pilots. Outcomes have been mixed and hard to verify independently, so treat large adoption claims with care.

Midnight

Midnight is a separate network for privacy-preserving smart contracts using zero-knowledge proofs. Its token, NIGHT, launched as a Cardano native asset in December 2025 and was distributed widely through a "Glacier Drop". Midnight's own mainnet started on 30 March 2026, initially run by a small federated set of operators with wider decentralisation planned.

Institutional and government notes

ADA futures began trading on CME in February 2026. In the United States there was no spot ADA exchange-traded fund at the time of writing: Grayscale withdrew its filing in August 2026. In March 2025 President Trump named ADA among assets for a US crypto reserve; the executive order that followed created a stockpile of forfeited assets and did not commit the government to buying any.

Roadmap and future

What comes next

Cardano's base layer is deliberately conservative, so most of the roadmap is about speed and capacity. Dates below are published targets, which have slipped before and need governance approval.

Target: late 2026

Ouroboros Leios

The headline scaling upgrade. "Linear Leios" lets block producers reference extra batches of transactions, certified by committees of stake pools, to raise throughput substantially while keeping the existing security model. It is planned to arrive with a new ledger era called Dijkstra.

Target: 2027

Ouroboros Peras

Adds a voting layer so that recent blocks can be treated as settled much sooner than today. Planned as a separate upgrade after Leios, with a published target of the second quarter of 2027.

Live, evolving

Hydra

A layer-2 system in which small groups open a "head", transact among themselves almost instantly, and settle the result on the main chain. Used in 2026 for a DEX and, notably, for the community's own budget voting.

Live

Mithril

Stake-based signatures that let a new node or light wallet trust a recent snapshot of the chain, cutting sync time from many hours to minutes.

In progress

More than one node

Amaru (Rust) and other independent node implementations aim to reduce reliance on the single Haskell codebase. Amaru's team has targeted block production on mainnet around November 2026.

In progress

Bitcoin, partner chains and stablecoins

Because Cardano and Bitcoin share the UTXO approach, several teams are building ways to use bitcoin in Cardano DeFi. Partner chains such as Midnight extend Cardano with specialised networks, and deeper stablecoin liquidity remains a stated priority.

Wallets

Choosing a Cardano wallet

A self-custody wallet holds the keys to your ADA, lets you stake and vote, and connects to apps. All of the wallets below let you keep control of your own recovery phrase. Listing is not endorsement; always download from the official site.

Lace

BrowserMobile

Input Output's light wallet, available as a browser extension and mobile app. Clean interface, staking to multiple pools, DApp and hardware-wallet support. The older Nami wallet was folded into it.

Eternl

BrowserMobile

Feature-rich community favourite with multi-account support, detailed staking and governance tools, and Ledger and Trezor support. Powerful, with a steeper learning curve.

Vespr

MobileBrowser

Mobile-first wallet for iOS and Android, also offered as a browser extension, aimed at ease of use, with native tokens, NFTs, staking and DApp connections.

Typhon

Browser

Browser extension and web wallet with straightforward staking, DApp support and hardware-wallet integration.

Yoroi

BrowserMobile

Emurgo's open-source light wallet, one of the oldest on Cardano. Simple setup on extension and mobile.

Daedalus

Desktop

Input Output's full-node desktop wallet. Downloads and verifies the entire chain itself, which is the most independent option but needs disk space and patience.

Tokeo

Mobile

iOS and Android wallet covering ADA, native tokens and NFTs with in-app DApp access and portfolio tracking.

Ledger

Hardware

Hardware devices that keep keys offline. Used together with a Cardano wallet such as Lace, Eternl or Typhon for staking and voting.

Trezor

Hardware

Open-source hardware wallets. Cardano support works through compatible software wallets on supported models.

Keystone

Hardware

Air-gapped hardware wallet that signs through QR codes rather than a cable, paired with a compatible Cardano wallet.

Tangem

Hardware

Card-shaped hardware wallet used with a phone app. Check current Cardano staking support before relying on it.

Three safety rules. Write your recovery phrase on paper and never type it into a website, chat or email. No genuine support agent will ever ask for it. Bookmark official sites, because fake wallet downloads are a common scam.

Where to buy and how to stake

Getting ADA, step by step

This is a neutral walkthrough, not a recommendation to buy. Availability depends on where you live, and you should only use money you can afford to lose.

Buying ADA

Pick a regulated exchange available in your country. ADA is listed on most large exchanges, including Coinbase, Kraken, Binance and Bybit. Compare fees and check which is licensed where you live.
Create and verify an account. Expect identity checks. Turn on two-factor authentication.
Fund it and buy. Deposit by bank transfer or card, then buy ADA. Check the total cost including spread and fees.
Consider moving it to your own wallet. Coins left on an exchange are controlled by the exchange. Withdraw to a self-custody wallet address, sending a small test amount first.

Staking ADA

Install a wallet from the wallets guide and back up the recovery phrase offline.
Open the staking section and browse pools. Look at fees (a fixed cost plus a margin), saturation, track record and whether the operator is independent. Spreading stake across smaller pools helps decentralisation.
Delegate. You sign one transaction, pay a small fee and a refundable 2 ADA deposit to register your stake key. Your ADA stays in your wallet.
Delegate your vote too. Choose a DRep or an abstain option so that rewards can be withdrawn later.
Wait. The first rewards arrive after about 15 to 20 days, then every five days. They are added to your stake automatically.

The Cardano community's own explainer is at cardano.org stake pool delegation.

Staking on an exchange is different from delegating from your own wallet: the exchange holds the coins and sets its own terms. Tax treatment of staking rewards varies by country; check local rules.

Risks and criticisms

The case against, fairly stated

No honest guide leaves this part out. Cardano has committed supporters and persistent critics; here are the main concerns and the usual responses.

Slow delivery

Smart contracts arrived in 2021, years after competitors, and major scaling work is still ahead. Supporters reply that careful engineering has avoided the catastrophic failures seen elsewhere. Critics reply that the market does not wait.

Low usage relative to its size

DeFi value, stablecoin supply, fees and developer counts are small compared with Ethereum and Solana, which is where the "ghost chain" jibe comes from. The 2026 integrations push is an attempt to fix this; whether it works is not yet known.

Governance growing pains

On-chain voting is new. Some 2026 votes passed or failed by narrow margins, turnout matters a great deal, and there has been open friction between DReps and the founding organisations over spending. Voting power is also concentrated among large holders.

Reliance on a few builders

Much of the core code still comes from Input Output, which has said it will no longer treat Cardano as its default home for new products. Alternative node teams and community funding reduce this risk but have not removed it.

Technical incidents

On 21 November 2025 a malformed transaction triggered a software bug that temporarily split the network into two chains. Intersect's incident report said no user funds were compromised and a fix was shipped the same day, but it ended the claim of a spotless record.

Developer experience

The eUTXO model and Haskell heritage make Cardano harder to pick up for developers used to Ethereum. Newer languages such as Aiken help, but tooling and bridges to other chains have lagged.

Regulatory uncertainty

In 2023 the US Securities and Exchange Commission described ADA as a security in lawsuits against two exchanges. Those cases were dropped in 2025 and Input Output always disputed the label, but rules differ by country and can change.

Market risk

ADA's price has swung enormously and has spent long periods far below its 2021 peak. Staking rewards are paid in ADA and do not protect you from a falling price. Nothing on this page is a reason to buy or sell.

Glossary

Cardano terms, decoded

Search the glossary

ADA: The native coin of Cardano, used for fees, staking and voting. Named after Ada Lovelace.
Lovelace: The smallest unit of ADA. One ADA equals 1,000,000 lovelace.
Ouroboros: The family of proof-of-stake protocols that decides who produces each Cardano block.
Proof of stake: A way of securing a blockchain where the right to add blocks depends on coins staked rather than computing power.
Epoch: A five-day period on Cardano. Stake snapshots and reward payments follow the epoch cycle.
Slot: A one-second window in which a block may be produced. Most slots are empty by design.
Stake pool: A server run by an operator that produces blocks on behalf of everyone who has delegated ADA to it.
SPO: Stake pool operator. The person or team running a stake pool.
Delegation: Assigning your ADA's staking weight to a pool, or its voting weight to a DRep, without transferring the coins.
Saturation: The point at which a pool holds so much stake that extra delegation lowers everyone's rewards. It encourages stake to spread out.
eUTXO: Extended unspent transaction output. Cardano's ledger model, in which coins exist as discrete outputs that can carry data and contract logic.
Plutus: Cardano's smart-contract platform. Contracts run as Plutus Core on-chain.
Aiken: A modern programming language created specifically for writing Cardano smart contracts.

Governance action: A formal on-chain proposal, such as a treasury withdrawal, parameter change or hard fork.
Treasury: An on-chain fund fed by a share of each epoch's rewards pot. Spending requires a governance vote.
Reserve: ADA that has not yet entered circulation. It is released gradually as rewards until the 45 billion cap is reached.
Hard fork: A protocol upgrade that changes the rules. Cardano uses a hard fork combinator so upgrades happen without splitting the chain.

Intersect: A member-based organisation that coordinates Cardano's open-source development and community processes.
Self-custody: Holding your own keys, usually via a recovery phrase, rather than leaving coins with an exchange.
Recovery phrase: The list of words that restores a wallet. Anyone who has it controls the funds, so it must stay secret and offline.

FAQ

Frequently asked questions

What is Cardano in simple terms?

Cardano is a public blockchain: a shared record of transactions kept by thousands of independent computers. Its coin is called ADA. People who hold ADA can stake it to help secure the network and can vote, directly or through representatives, on how the network is upgraded and how its treasury is spent.

Who created Cardano?

Cardano was founded by Charles Hoskinson and Jeremy Wood, who both worked on Ethereum before leaving in 2014. They set up the engineering company IOHK, now called Input Output, in 2015. The network launched on 27 September 2017.

What is the difference between Cardano and ADA?

Cardano is the network. ADA is the coin that runs on it. ADA is used to pay transaction fees, to stake, and to vote in governance. The smallest unit of ADA is a lovelace, which is one millionth of an ADA.

How many ADA will ever exist?

The maximum supply is 45 billion ADA. Roughly 31.1 billion existed at launch. The remainder is held in a reserve that the protocol releases gradually as staking rewards and treasury income, so new issuance shrinks over time.

Is staking ADA safe, and are my coins locked?

When you delegate from your own wallet, your ADA stays in your wallet, is never locked and can be spent at any time, and there is no slashing of your principal. The risks that remain are the usual ones: the price of ADA can fall, rewards vary, and you must keep your recovery phrase safe. Staking through an exchange is different because the exchange holds your coins.

How much can I earn by staking ADA?

There is no fixed rate. Rewards depend on the pool you choose, its fees and performance, and how much ADA is staked across the whole network, and they have declined over the years as the reserve shrinks. The estimator on this page lets you try your own assumptions, but it is an illustration and not a promise.

Who controls Cardano today?

No single organisation. Since the Chang and Plomin upgrades in 2024 and 2025, changes are decided by on-chain votes of three groups: delegated representatives chosen by ADA holders, stake pool operators, and a Constitutional Committee that checks proposals against the Cardano Constitution.

Which wallet should I use for Cardano?

It depends on your device and experience. Lace, Eternl, Typhon and Yoroi are popular browser wallets, Vespr and Tokeo are mobile wallets, Daedalus is a full-node desktop wallet, and Ledger, Trezor and Keystone are hardware wallets that work with them. Always download from the official site and never share your recovery phrase.

Is there a Cardano ETF?

At the time of writing in October 2026 there was no spot ADA exchange-traded fund in the United States. Grayscale withdrew its application in August 2026. Regulated ADA futures have traded on CME since February 2026, and a small futures-based fund exists. This can change, so check current sources.

What are the main criticisms of Cardano?

Critics point to slow delivery of features, low usage compared with Ethereum and Solana, a small stablecoin and DeFi footprint, a steeper learning curve for developers, and friction in its young governance system. Supporters argue that careful engineering, strong decentralisation and holder-led governance are worth the trade-off.
