While confidentiality on the blockchain network protects users from hacks and preserves privacy, it also allows for illegal trading and activity on the blockchain network. The most cited example of blockchain being used for illicit transactions is probably the Silk Road, an online dark web illegal-drug and money laundering marketplace operating from February 2011 until October 2013, when the FBI shut it down.
This system can be seen as both a pro and a con. It gives anyone access to financial accounts, but allows criminals to transact more easily. Many have argued that the good uses of crypto, like banking the unbanked, outweigh the bad uses of cryptocurrency, especially when most illegal activity is still accomplished through untraceable cash.
A smart contract is computer code that can be built into the blockchain to facilitate transactions. It operates under a set of conditions to which users agree. When those conditions are met, the smart contract conducts the transaction for the users.
Why do this? The food industry has seen countless outbreaks of E. coli, salmonella, and listeria; in some cases, hazardous materials were accidentally introduced to foods. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating.
A blockchain is a distributed network of files chained together using programs that create hashes, or strings of numbers and letters that represent the information contained in the files. Every network participant is a computer or device that compares these hashes to the one they generate. If there is a match, the file is kept. If there isn’t, the file is rejected.

It would be interesting to know if PSD2 has had an impact on how everyday consumers choose to pay, especially in Europe. Barclaycard Payments metrics indicated that 17% of European ecommerce transactions were soft-declined since the introduction of SCA mandates, per figures presented by the bank at MPE Berlin 2022. Merchants did take note, but did this affect consumer behavior as well?
Commercial Bank Money Tokens (also sometimes called deposit tokens) are a form of digital money representing a claim against the bank issuing the token. From a bank’s perspective it is digitizing (tokenizing) the deposits a customer has at the bank and making them available in its digital form today typically on a private, permissioned blockchain.
As we move towards 2025, businesses must adapt to this shift by ensuring they have the infrastructure to support contactless payments. This includes upgrading point-of-sale systems and educating staff on the benefits and security of these transactions. Consumers, on the other hand, should stay informed about the latest contactless payment options and understand how to use them safely to protect their financial information.
The ease of use and enhanced security features make digital wallets a preferred choice for consumers. They allow for faster checkouts, reducing friction in the purchasing process. Businesses should consider integrating these payment options to streamline their checkout processes and enhance customer satisfaction.
For any company active in regions with shifting regulations, a clear understanding of their payment landscape is instrumental to smooth transition. For example, a lot of these regulations have something to do with transaction value – they might apply to everything over a specific value or exemptions might require a maximum value. Considering your average transaction value can help demonstrate whether it is worth exploring such exemptions.
Fiat-backed stablecoins like the US Dollar Coin (USDC) or PayPal USD (PYUSD) are a form of money issued by a private, regulated entity. These issuers get traditional money, also called FIAT, and for each dollar they receive they create one stablecoin token and use the FIAT money as collateral in the form of short-term government securities or cash holdings. Europe has a clear regulatory framework called Market in Crypto Regulation (in short MiCA) that governs issuance and use of stablecoin. Stablecoin is live on different public blockchains and can be easily moved from one party to another in real-time, 24/7 at very low transaction fees.
