Are you wondering if Web3 will disrupt the way you sell online? Not just yet, but it could well transform large-scale transactions and digital trust. For a merchant, understanding this evolution means anticipating tomorrow's expectations.
Web3 promises a "trustless" web where every exchange is verified, but it remains experimental and will coexist with Web2 for a long time. So, will Web3 change e-commerce? On the agenda:
What is Web3 and how does it differ from Web2?
Why is Web3 described as the "web of truth"?
How could Web3 secure transactions worth several million euros?
What are the technical and legal challenges before massive adoption?
How to prepare your Shopify store for this transition?
Let's get started.
Summary
What is Web3 and why is everyone talking about it?
Web3, also known as web 3.0, is a concept attracting growing interest. Google searches for this term peaked at the end of 2021, with a volume about 20 times higher than the previous year. For a merchant, understanding this trend means seizing an opportunity for differentiation.
In concrete terms, Web3 is an evolution of the current web. The original internet, in the 1960s, was an academic and military project. Then Web1 allowed for the sharing of static files, and Web2 added interactivity and social networks. Web3, on the other hand, proposes to decentralize authority and verify every identity and intention.
To borrow the vision of Juan Benet, CEO of Protocol Labs, Web3 is not the "read-write-execute" imagined by pioneers, but rather "read-write-truth": a web where truth is verified, not simply trusted.
This evolution is not limited to technology: it redefines power relationships between platforms, users, and merchants. As a merchant, you could one day directly control your data and that of your customers, without relying on intermediaries. This is a perspective that deserves your attention, even if it remains distant.

Why is trust the central problem of Web2?
Today, when you buy online, you must trust a chain of actors: the merchant, the payment processor, the hosting provider, and even the authorities that guarantee security protocols. This trust is implicit, but it is not always earned.
Take recent examples: in 2021, more than 100 million Android users had their data exposed by applications. Facebook suffered a leak of 553 million accounts, and LinkedIn lost 700 million records. These incidents show that centralized authorities can fail.
For an e-commerce merchant, this means that customer trust is fragile. If your data or that of your customers is compromised, your reputation suffers. Web3 aims precisely to eliminate this need for blind trust.
Furthermore, trust in Web2 is often asymmetrical: large platforms hold considerable power over your sales and visibility. An algorithm change can reduce your traffic overnight. Web3, by decentralizing data and transactions, could offer you greater autonomy and a more direct relationship with your customers.
What is the "web of truth" and how does it work?
Web3 starts from the principle that no organization is trustworthy by default. It therefore verifies every identity and every intention with each transaction. This is what is called a "trustless" system: trust is replaced by cryptographic proof.
To use the words of Gavin Wood, co-founder of Ethereum and president of the Web3 Foundation, the next generation of the web will not have trust, but it will have truth. Concretely, every action is recorded and verifiable, which reduces the risk of fraud.
For a merchant, this could mean more secure transactions with fewer disputes. But it also implies rethinking your payment processes and customer data management.
Imagine a customer buying an expensive product: with Web3, they could verify the authenticity of the item and its supply chain history before paying. This would strengthen their confidence and could reduce returns and complaints. For you, this means a more transparent and solid customer relationship, based on proof rather than promises.
Can Web3 secure multi-million euro transactions?
Gavin Wood describes Web3 as an extensible framework for creating massively multi-user and economically strong applications. This means that applications would be robust enough to handle very high-value transactions, such as agreements worth several hundreds of millions of euros.
Today, an online payment of a few thousand euros is common. But for a contract of 10 million euros, parties prefer lawyers and legal jurisdictions. Web2 does not inspire enough trust for this level of transaction.
Web3, thanks to decentralization and cryptographic verification, could offer strong guarantees. For an e-merchant, this opens the door to large-scale B2B sales, without going through costly intermediaries.
Take the example of a wholesaler selling electronic components to a manufacturer: a smart contract could automate payment as soon as delivery is verified, reducing delays and risks of non-payment. This could transform business negotiations and make international trade more fluid, even for SMEs.
What are the current security risks in Web2?
Security breaches are commonplace in Web2. In 2021, app developers inadvertently exposed the personal data of over 100 million Android users. Hackers also scraped the information of 553 million Facebook users.
LinkedIn lost control of 700 million records, including names, phone numbers, addresses, and geolocation data. These incidents are not isolated errors, but symptoms of a system that relies on trust in fallible authorities.
For a merchant, these examples highlight the importance of protecting customer data. Web3, by verifying every transaction, could reduce these risks, but it will take time to be adopted on a large scale.
In the meantime, you can already strengthen the security of your store: use strong passwords, enable two-factor authentication, and encrypt sensitive data. These simple measures reduce your exposure to cyberattacks and reassure your customers, a significant competitive advantage.
How could smart contracts transform transactions?
Imagine two companies entering into a €10 million agreement. Today, they would use lawyers and legal contracts. With Web3, these transactions could be executed via smart, automatic, and verifiable contracts.
These contracts are recorded on a blockchain, which guarantees their execution without an intermediary. This reduces costs and delays, while increasing security. For an e-merchant, this potentially means smoother and more secure B2B sales.
However, this technology is still theoretical. Web3 applications are not yet mature enough to handle transactions of this scale, but the foundations are laid.
For example, platforms like Ethereum are already testing smart contracts for real estate transactions or auctions. If these experiments succeed, they could inspire solutions adapted to e-commerce, such as automated cash on delivery or dispute resolution without a court.
Will Web3 replace Web2?
Web3 is generating a lot of interest, but it has not yet produced the effects described by its promoters. Decentralized applications are still slow, complex, and not very accessible to the general public. Furthermore, almost no one imagines that Web3 will replace Web2.
The two will coexist for years. Web2 will remain dominant for daily uses, such as social networks and traditional e-commerce. Web3, on the other hand, will develop in parallel, particularly for specific use cases like high-value transactions.
For a merchant, it is therefore prudent to continue optimizing your Web2 store while monitoring the developments of Web3.
In practice, you can follow technology news, participate in webinars, or test decentralized applications on a small scale. This monitoring will allow you to identify opportunities as soon as they become relevant, without taking unnecessary risks.
What are the technical challenges of Web3?
Web3 relies on technologies like blockchain, which are still slow and energy-intensive. Transactions can take several minutes and fees are high. For an e-merchant, this makes adoption for daily payments difficult.
In addition, the user experience is often complex: it requires managing cryptographic wallets, private keys, and unintuitive interfaces. This slows down adoption by the general public.
Finally, regulation is still unclear. Authorities have not yet defined a clear framework for decentralized transactions, which creates uncertainty for businesses.
However, solutions are emerging to improve scalability, such as Layer 2 protocols that reduce costs and speed up transactions. These advancements could make Web3 more accessible in the coming years, but it is still too early to rely on it.
What are the legal challenges of Web3?
Web3 raises complex legal questions. For example, who is responsible in the event of a dispute over a decentralized transaction? Are smart contracts legally binding? Answers vary by country.
Do data protection laws, such as GDPR, apply to decentralized applications? Since the blockchain is immutable, it is difficult to delete personal data, which conflicts with the right to be forgotten.
For a merchant, these uncertainties make adopting Web3 for sensitive operations risky. It is preferable to wait for the regulatory framework to become clearer.
In the meantime, consult legal experts to understand the implications of these technologies in your country. Regular monitoring of court decisions and European directives will help you anticipate developments and adapt your strategy accordingly.
How to prepare your Shopify store for Web3?
Even if Web3 is not yet mature, you can anticipate. Start by educating yourself on blockchain technologies and cryptocurrencies. Test crypto payment solutions if your customer base is receptive.
Strengthen the security of your current store: use two-factor authentication, encrypt sensitive data, and train your team on best practices. A solid foundation will allow you to adopt future innovations more easily.
Finally, monitor regulatory developments and concrete use cases. Web3 could offer opportunities, but it is better to be an early adopter than a risky pioneer.
For example, some luxury brands are already using NFTs to certify the authenticity of their products. You could explore similar applications for your high-end items, in order to build trust and differentiate yourself from the competition.
