Web3 and Blockchain: What Are We Really Talking About?

« Web3 », « blockchain », « cryptocurrencies », « NFT » : these words keep coming up, surrounded by grand promises (« the revolution of the Internet ») as well as scandals (scams, speculation, bankruptcies). It’s hard to navigate between the enthusiasm of some and the distrust of others. What are we really talking about? Without jargon or bias, here is a clear and balanced explanation of Web3 and blockchain: what it is, what it promises, the criticisms and the risks — to form your own opinion, keeping your feet on the ground.

Blockchain and Web3: what are we talking about?

Let’s start with the BLOCKCHAIN, the base technology. In simple terms, it’s a kind of DIGITAL, SHARED, and DECENTRALIZED REGISTER (a large ledger): instead of being held by a single authority (a bank, a company), it is distributed and verified by a NETWORK of computers; the information is recorded in a way that is difficult to modify (secured by cryptographic mechanisms). The idea: to allow the recording and exchange of things (transactions, « tokens ») WITHOUT going through a central trusted intermediary; this is « decentralized » trust. The blockchain is the technology behind CRYPTOCURRENCIES (digital currencies like bitcoin, exchanged on blockchains) and other applications. WEB3 is a broader concept: it’s a VISION of a more DECENTRALIZED Internet, built on blockchains, where users would have more control over their data, their digital assets, without being as dependent on centralized large platforms (the current « Web2 », dominated by a few giants). Associated concepts include: CRYPTOCURRENCIES, NFTs (tokens representing ownership of a unique digital object — an image, a virtual object), decentralized applications, decentralized organizations… The PROMISES of Web3: more DECENTRALIZATION (less power to giants, more to users), more CONTROL over your data and assets, new forms of DIGITAL PROPERTY and exchange, the ability to transact without intermediaries. Its supporters see it as a « revolution » of the Internet, more free and more equitable. BUT we must be HONEST: Web3 is a CONTROVERSIAL field, between promises and realities, where the best coexists with the worst. There is a lot of HYPE (hype, exaggerated promises), SPECULATION (people are mainly looking for quick gains), and unfortunately SCAMS (the field attracts scammers). Criticisms are numerous: complexity, concrete uses still limited for the general public, risky speculation, ecological cost of some blockchains, frequent scams. What you need to understand: Web3 and blockchain are REAL technologies with interesting ideas (decentralization), but surrounded by enormous HYPE, speculation, and risks; you need to separate the concepts from the promises and the scams. The main idea: the blockchain is a decentralized digital register (shared by a network, difficult to modify) that allows exchanges without a central intermediary; Web3 is a vision of a more decentralized Internet built on it (cryptocurrencies, NFTs, decentralized applications). Interesting ideas, but a very controversial field, mixing grand promises, speculation, complexity, and scams. Understanding what it is about allows you to approach the subject with discernment, without being carried away by enthusiasm or panic.

Between promises and risks: keeping your feet on the ground

When faced with Web3 and blockchain, the best attitude is DISCERNMENT: recognizing the interesting ideas, but keeping your feet on the ground in the face of hype and risks. The INTERESTING IDEAS: DECENTRALIZATION (less dependence on centralized giants) is a concept that appeals; blockchain has real potential applications (beyond speculation); there are technological avenues worth paying attention to. The REALITIES to temper: many promises of Web3 remain THEORETICAL or not very concrete for the general public; truly useful daily uses are still limited; the field is COMPLEX (difficult to understand and use); and a large part of the activity is SPECULATION (buying in the hope of selling at a higher price), not actual use. The SERIOUS RISKS to know: SPECULATION is very RISKY — cryptocurrencies and NFTs are extremely VOLATILE (their value can collapse; many people have lost money); NEVER put money into these assets that you cannot afford to lose. SCAMS are FREQUENT: the field attracts scammers (fake cryptos, fake projects, promises of huge gains, thefts); be VERY WARY (our guides on recognizing scams). COMPLEXITY exposes you to errors (losing access, being hacked; in Web3, an error can be irreversible — no « customer service » to recover). The ECOLOGICAL COST of some blockchains is an issue (energy consumption — our guides on AI and ecological cost, in echo). The REGULATORY UNCERTAINTY: a field still poorly regulated, which increases the risks. How to APPROACH the subject with common sense:

• UNDERSTAND before acting — do not invest in what you do not understand (a golden rule: many have lost money by buying cryptos or NFTs without understanding them)
• Be wary of PROMISES of gains — « get rich », « guaranteed gains » are scam signals; there is no easy money
• Only risk what you can AFFORD to lose — if you get involved, consider that you could lose everything
• BEWARE of scams — extremely frequent in this field; maximum caution
• Keep your CRITICAL SPIRIT — in the face of enthusiasm as well as announcements; distinguish technology from speculative promises
• You are NOT obliged to participate — do not give in to social pressure or the fear of « missing out »; it is perfectly reasonable to stay away, especially if you do not understand it

Some ADVICE: inform yourself from RELIABLE and neutral sources (not « influencers » who have an interest in selling you a dream); distinguish TECHNOLOGY (blockchain, interesting) from SPECULATION (risky); and remember that understanding does not mean investing. In summary, Web3 and blockchain carry interesting ideas (decentralization), but the field is surrounded by hype, risky speculation, and frequent scams: keep your feet on the ground. Understand before acting, be wary of promises of gains and scams, only risk what you can afford to lose, keep your critical spirit, and know that you are not obliged to participate. Discernment, not excitement.

The right reflex. When faced with Web3, blockchain, cryptocurrencies, and NFTs, keep your feet on the ground: recognize that there are interesting ideas (decentralization — less dependence on giants), but separate TECHNOLOGY (potentially interesting) from SPECULATION (very risky) and SCAMS (frequent). The absolute golden rule: NEVER invest in what you do not understand. Many people have lost money by buying cryptos or NFTs without understanding them, carried away by the hype or the fear of « missing out ». If you do not grasp how it works and what you are buying, wisdom dictates staying away: you are NOT obliged to participate, and it is perfectly reasonable not to do so. Be VERY WARY of promises of gains: « get rich », « guaranteed gains », « exceptional returns » are classic SCAM signals; there is no easy money, and the field massively attracts scammers (fake cryptos, fake projects, thefts). If you still decide to get involved, only risk what you can afford to LOSE: cryptos and NFTs are extremely volatile, their value can collapse, and in Web3, an error (losing access, being hacked) is often IRREVERSIBLE — no customer service to recover your money. Inform yourself from RELIABLE and neutral sources, never from « influencers » who have an interest in selling you a dream. Keep your critical spirit in the face of enthusiasm as well as announcements, and do not give in to social pressure or the fear of missing an opportunity. Remember that UNDERSTANDING the subject (to form an opinion) does not mean INVESTING. Understanding before acting, being wary of promises of gains and scams, only risking what you can afford to lose, and knowing that you can stay away: this is how you approach Web3 with discernment, without being carried away by excitement or trapped by scammers. The hype promises wonders; caution protects your money and your peace of mind.

Forming your own opinion, with discernment

Web3 is a subject where you are torn between convinced enthusiasts and radical skeptics; the best position is to form YOUR OWN opinion, with discernment. Some guidelines. The NECESSARY NUANCE: neither « revolution that will change everything » nor « total scam »; reality is more nuanced — real technological ideas, mixed with a lot of hype, speculation, and scams; separate the wheat from the chaff. The DISTINCTION between technology and speculation: the blockchain (the technology) and speculation on cryptos/NFTs (the risky financial activity) are two different things; you can find the first interesting without engaging in the second. The DISTANCE from the hype: the field generates disproportionate enthusiasm (and financial interests to convince you); keep your distance, inform yourself from neutral sources, be wary of « we’re all going to get rich ». FINANCIAL PRUDENCE: if you get involved with these assets, treat them as very risky (volatility, scams, irreversibility); only put in what you can afford to lose; speculation is not savings. The FREEDOM not to participate: you can very well stay away; understanding the subject does not oblige you to do anything; do not give in to fashion or the fear of missing out. The EVOLUTION to follow: the field changes (projects are born and die, regulations progress); stay informed if the subject interests you, without rushing. CRITICAL SPIRIT, always: in the face of promises as well as catastrophic speeches, keep your judgment; it is your best protection. In summary, Web3 and blockchain are real technologies carrying interesting ideas (decentralization, exchanging without a central intermediary), but the field is very controversial: between grand promises, risky speculation, complexity, and frequent scams. To navigate: understand what it is about (blockchain = decentralized register; Web3 = vision of a decentralized Internet built on it), distinguish technology from speculation, keep your feet on the ground in the face of hype, be extremely cautious (scams, volatility, only risk what you can afford to lose), and know that you are not obliged to participate. Form your own opinion with discernment, without being carried away by the enthusiasm of some or the panic of others. Web3 is neither the miracle revolution that some promise, nor necessarily the total scam that others denounce: it is a complex and risky field, with interesting ideas drowned in a lot of noise and excesses. The right attitude: inform yourself to understand, keep your critical spirit and your caution, and decide in full knowledge of the facts — including deciding to stay away, which is often the wisest choice for those who do not understand it. In the face of hype, discernment and keeping your feet on the ground are your best allies.

Warning: very risky speculation, numerous scams, and irreversible errors. Web3 is a HIGH-RISK field; these warnings are essential. DANGEROUS SPECULATION — cryptocurrencies and NFTs are extremely VOLATILE: their value can rise, but also COLLAPSE suddenly; many people have LOST money, sometimes everything; this is NOT safe savings, it is high-risk speculation; NEVER put money into these assets that you need or cannot afford to lose; and be wary of anyone who presents this as a « safe » or « guaranteed » investment. OMNIPRESENT SCAMS — the field massively attracts SCAMMERS: fake cryptocurrencies, fake projects, fake platforms, promises of huge gains, wallet thefts, « opportunities » too good to be true; scams related to cryptos are countless and sophisticated; be VERY WARY: any promise of quick or guaranteed gains is a scam signal, never entrust your access or your money to a stranger, a message, or an « influencer » (our guides on recognizing scams). IRREVERSIBLE ERRORS — in Web3, there is often NO safety net: no bank or customer service to cancel a transaction, recover lost access, or refund you in case of scam or error; a lost key, a wrong transfer, a hack can mean a DEFINITIVE loss; this lack of recourse makes every error potentially costly. Other points: COMPLEXITY (do not invest in what you do not understand — this is the first cause of losses), SOCIAL PRESSURE (do not give in to the fear of « missing out » or fashion — you can stay away), REGULATORY UNCERTAINTY (little protection), the ECOLOGICAL COST of some blockchains, and « INFLUENCERS » with vested interests (who promote projects they benefit from — inform yourself from neutral sources). Web3 carries interesting ideas, but it is a field where the worst coexists with the best, and where imprudence is costly. The only reasonable attitude is DISCERNMENT: understand before acting, be extremely wary of scams and promises of gains, only risk what you can afford to lose, and know that you can perfectly — and often wisely — not participate at all. Do not let the hype or the fear of missing out make you take reckless risks with your money: in this field more than anywhere else, caution is your best protection.

Frequently asked questions

What is the blockchain, simply?

In simple terms, it is a kind of DIGITAL, SHARED, and DECENTRALIZED REGISTER (a large ledger). Instead of being held by a single authority (a bank, a company), it is distributed and verified by a NETWORK of computers; the information is recorded in a way that is difficult to modify (secured by cryptography). The idea: to allow the recording and exchange of things (transactions, « tokens ») WITHOUT going through a central trusted intermediary — this is « decentralized » trust. The blockchain is the technology behind cryptocurrencies (digital currencies like bitcoin) and other applications (like NFTs). It is a real technology, with interesting ideas (decentralization, exchanging without an intermediary). But it is complex, and above all surrounded by a lot of hype, speculation, and scams: you need to distinguish the technology itself (potentially interesting) from the risky speculative uses (cryptos, NFTs) that make the headlines. Understanding what the blockchain is helps you approach the subject with discernment, without being carried away by grand promises or panic.

Should you invest in cryptocurrencies or NFTs?

This is neither advice to give lightly, nor an obligation: caution is required. Cryptocurrencies and NFTs are extremely RISKY and VOLATILE assets: their value can collapse suddenly, and many people have lost money, sometimes everything; this is NOT safe savings, it is high-risk speculation. Rules of common sense: NEVER invest in what you do not understand (first cause of losses); only put in money that you can afford to LOSE entirely; be very wary of promises of quick or guaranteed gains (scam signals); and remember that the field is riddled with scams, and that an error or a hack is often irreversible (no recourse). Above all: you are NOT obliged to participate; do not give in to the fear of « missing out » or social pressure; it is perfectly reasonable, and often wise, to stay away, especially if you do not understand it. If you still want to get involved, first inform yourself seriously from reliable and neutral sources (not interested influencers), and only commit amounts you are ready to lose. In matters of cryptos and NFTs, extreme caution is required.

Is Web3 the future of the Internet?

No one can affirm it: the subject is highly debated, and reality is nuanced. Its supporters see it as a « revolution » — a more decentralized Internet, where users would have more control over their data and assets, less dependent on giants. It is a vision that carries interesting ideas (decentralization). But its critics point out that many promises remain theoretical, that concrete and useful uses for the general public are still limited, that the field is complex, and that a large part of the activity is speculation and scams rather than real use. The honest truth: we do not know if Web3 « will be the future of the Internet »; there are real technological avenues here, but drowned in a lot of hype, excesses, and uncertainties. Neither « inevitable revolution » nor « total scam »: reality is in between, and evolving. The right attitude: inform yourself to understand, keep your critical spirit in the face of enthusiasm as well as catastrophism, stay cautious (especially financially), and form your own opinion without rushing. You can follow the subject with interest and detachment, without having to « believe in it » or invest in it: understanding does not oblige you to do anything.

What to remember

The BLOCKCHAIN is, in simple terms, a DECENTRALIZED DIGITAL REGISTER: a « large ledger » shared and verified by a network of computers (rather than held by a single authority), and difficult to modify; it allows the recording and exchange of things WITHOUT a central intermediary (the « decentralized » trust). It is the technology behind CRYPTOCURRENCIES (bitcoin…) and NFTs (tokens of ownership of digital objects). WEB3 is a broader VISION: a more decentralized Internet built on blockchains, where users would have more control over their data and assets, less dependent on giants. Its promises (decentralization, control, new forms of digital property) are appealing; its supporters see it as a « revolution ». BUT the field is very CONTROVERSIAL, between grand promises and realities: a lot of HYPE, still limited uses, complexity, RISKY SPECULATION, and FREQUENT SCAMS. The right attitude is DISCERNMENT: recognizing the interesting technological ideas (decentralization), but keeping your feet on the ground. Distinguish TECHNOLOGY (blockchain, potentially interesting) from SPECULATION (on cryptos and NFTs, very risky) — you can be interested in one without engaging in the other. Essential rules of caution: NEVER invest in what you do not understand (first cause of losses); cryptos and NFTs are extremely VOLATILE (their value can collapse — only risk what you can afford to lose); be VERY WARY of scams (ubiquitous in this field — any promise of quick or guaranteed gains is a scam signal); and know that errors are often IRREVERSIBLE (no customer service to recover). Inform yourself from RELIABLE and neutral sources (not interested influencers), keep your critical spirit in the face of enthusiasm as well as catastrophism, and remember that you are NOT obliged to participate: staying away is often the wisest choice, especially if the subject eludes you. Web3 is neither the miracle revolution that some promise, nor necessarily the total scam that others denounce: it is a complex and risky field, with interesting ideas drowned in a lot of noise and excesses. Understanding what it is about, distinguishing technology from speculation, staying extremely cautious, and forming your own opinion with discernment: this is how you approach the subject without being carried away by excitement or trapped by scammers. In the face of hype, keeping your feet on the ground and your critical spirit are your best allies — and your best protection.
