모든 크립토 채널에는 같은 다급한 경고가 고정되어 있습니다. "운영진은 절대 먼저 DM을 보내지 않습니다." 이 책은 그 한 줄 뒤에 숨은 스캠 경제의 필드 가이드입니다. 사칭 관리자, 딥페이크로 만들어진 창업자, 피그 부처링, 통째로 합성된 커뮤니티까지 — 스팸에서 크립토, 그리고 AI로 이어지는 세 시대를 가로질러 추적하고, 이 모든 것을 끝낼 단 하나의 질문에 도달합니다. 지금 이 방에 누가 있는가?

Todos hemos oído hablar de la Web3, de las criptomonedas, de las cadenas de bloques (blockchains), de los NFT y de las DAO. Casi nadie sabe decir, con claridad, qué **es** en realidad cada una de esas cosas, ni si se trata del futuro de internet o de una manera elaborada de perder dinero. **El libro de la Web3** por fin le da una respuesta directa.

웹3, 암호화폐, 블록체인, NFT, 다오(DAO) — 못 들어 본 사람은 없다. 그러나 그것이 정확히 무엇**인지**, 인터넷의 미래인지 아니면 돈을 잃는 정교한 방법인지 분명하게 말할 수 있는 사람은 거의 없다. **『웹3란 무엇인가』**는 마침내 그 질문에 정면으로 답한다.

Everyone has heard of Web3, crypto, blockchains, NFTs, and DAOs. Almost no one can say, clearly, what any of it actually is — or whether it's the future of the internet or an elaborate way to lose money. The Web3 Book finally gives you a straight answer.

Every crypto channel pins the same frantic warning: the admins will never DM you first. This is the field guide to the scam economy behind that line — impersonated admins, deepfaked founders, pig-butchering, and entire synthetic communities — traced across three eras, from spam to crypto to AI, and the one question that ends it: who is in the room?

Four colleagues. One whiteboard. Ten Thursdays to understand the thing everyone argues about, and almost no one can explain. Margaret has been handed a single page to fill out: a recommendation, by quarter-end, on whether her insurance company should invest in Bitcoin. She means to write *NO* and be home by five. But to write *NO* with a clear conscience, she first has to understand it - and that turns out to take longer than an afternoon. What follows is the clearest explanation of Bitcoin ever told as a story. No hype. No jargon. No get-rich pitch - just four sharp, skeptical adults breaking the thing open one piece at a time, from *there is no coin* to the twelve words that can hold a fortune, discovering that the machine they were sent to dismiss is harder to cheat than the bank. If you've ever nodded along to the word *blockchain* and quietly prayed no one wouldask you what it meant - this is the book that finally makes it make sense.

As decentralized finance matures on Cardano, the role of secure infrastructure and reliable market data becomes critical for sustaining complex financial protocols. Indigo Protocol, the network’s leading synthetic asset platform, represents a key driver of on-chain activity through collateralized positions, trading, and asset issuance.Through coordinated Catalyst-funded investments in security auditing and real-time data infrastructure, Indigo demonstrates how tightly integrated upgrades can strengthen protocol resilience while enabling continued growth in user activity. Part of the 12-part On-Chain Impact Study, this case study examines how synthetic asset infrastructure contributes to transaction volume, market dynamics, and network utility, offering data-driven insights into DeFi’s evolving role on Cardano.

As blockchain ecosystems expand, developer infrastructure plays a critical role in enabling adoption, even when its impact is not directly visible on-chain. Mesh SDK was developed to simplify building on Cardano, providing tools, libraries, and integrations that power a growing number of applications across the ecosystem.Through continuous upgrades, protocol support, and widespread developer adoption, Mesh demonstrates how foundational tooling can drive network activity indirectly through downstream integrations. Part of the 12-part On-Chain Impact Study, this case study examines how developer infrastructure contributes to ecosystem growth, offering data-driven insights into how SDK adoption translates into measurable on-chain usage.

As blockchain adoption expands into public sector systems, proving real-world usage through verifiable on-chain data becomes essential. Trivolve Tech’s Forensic Management System (FMS) represents a government-focused deployment designed to bring transparency, traceability, and data integrity to forensic workflows using Cardano infrastructure. Through large-scale transaction activity, oracle integration, and cross-network deployment, the project demonstrates how enterprise and government use cases can generate measurable on-chain impact. Part of the 12-part On-Chain Impact Study, this case study examines how forensic data systems contribute to network growth, offering data-driven insight into the role of public sector adoption in expanding blockchain utility.
