Most people meet blockchain through cryptocurrencies, but the technology reaches much further. In iGaming it already powers crypto payments and a growing number of on-chain games, and every one of those projects still has to answer the same question as a traditional casino: which licence will it operate under?
How a blockchain works
A blockchain is a sequence of linked records, or blocks, each holding encoded information. Every block stores three things:
- Data: in Bitcoin's case, the sender, the recipient and the amount of a transaction.
- Its own hash: a unique identifier that works much like a fingerprint.
- The previous block's hash: the link that ties each block to the one before it.
Because each block points back to its predecessor, the records form a chain. Changing one block would break the links that follow it, which is what makes the ledger so hard to alter quietly.
A short history
The idea is older than cryptocurrency. In 1991, researchers Stuart Haber and W. Scott Stornetta described a way to timestamp digital documents so that they could not be tampered with or backdated. The concept stayed niche until Bitcoin arrived in 2009, created by Satoshi Nakamoto, a name that may belong to one person or to a group.
Where blockchain is used today
Payments and money transfers remain the best-known use. Cutting out intermediaries speeds things up, and some crypto transactions settle in a few seconds. Beyond finance, blockchains are used to:
- keep medical records, reducing paperwork and protecting patient privacy;
- provide e-notary services;
- track goods through supply chains;
- share data securely;
- support digital voting and even tax collection.
Blockchain in online gambling
For casinos, the first step is usually crypto payments. Many operators and platform providers accept Bitcoin and other coins next to fiat money. Our Bitcoin casino solution lets players pay in popular cryptocurrencies such as Bitcoin, Litecoin and Ethereum, as well as coins built on them, and a crypto payment gateway can be added to an existing brand.
A newer step is building the games themselves on a blockchain, so that the currency used inside the game is a cryptocurrency. Each of these projects is engineered individually and the technical design is usually a trade secret of the operator. The field is still young, so an operator who launches a well-built crypto product now can stand out with a genuinely new offer.
Licensing a crypto or blockchain casino
Running real-money games on a blockchain does not remove the need for a gambling licence. What changes is the extra scrutiny that crypto brings:
- Check the jurisdiction's position on crypto. Regulators differ on whether, and how, licensees may accept cryptocurrency.
- Expect a longer review. Registration and due diligence for crypto projects can take more time than for a fiat-only casino.
- Prepare the paperwork. Certificates for your games and a solid business plan are typically part of the application.
Curaçao has long been the most common route for crypto casinos. Its framework changed under the National Ordinance on Games of Chance (LOK), which replaced the old master licence and sub-licence system with licences issued directly by the Curaçao Gaming Authority. Rules are still evolving, so confirm the current requirements before you file. Read our overview of gambling licensing in Curaçao, or compare it with the Anjouan licence.
Next steps
If you are planning a crypto or blockchain casino, settle the licence early, because it shapes your payment setup, your game portfolio and your launch timeline. Our licensing support page explains how we help operators prepare, and you can contact us to talk through your project.
