Most dApps still host their frontends on centralized servers. Raymond Khalife from DFINITY Foundation explains how the Internet Computer serves web frontends directly from smart contracts using: - HTTP gateways - Certified data - The Asset Canister Apps like OpenChat ∞ and ICP Ninja already run fully onchain.

Internet Computer the industry's fastest blockchain this week. DFINITY Foundation's Internet Computer recorded an insane 2,637 transactions per second this week. This makes $ICP the fastest blockchain across the seven-day period according to Chainspect data. Is Internet Computer due for a resurgence this year...?

What is HTTP Downgrading, why use it, and how does it work? HTTP/2 is default for most web apps these days, however, it's not uncommon for backend servers to still use HTTP/1.1 causing parsing mismatches between frontend and backend. And that's where HTTP downgrading comes in! But what is it? HTTP downgrading is the process of forcing a request to be processed under HTTP/1.1 instead of HTTP/2. This allows you to manipulate how the frontend and backend servers interpret requests and exploit vulnerabilities unique to HTTP/1.1 parsing such as Content-Length Transfer-Encoding (CL.TE) attacks. How to downgrade HTTP/2 to HTTP/1.1 using Burp Suite 1️⃣ Open Burp Suite and Navigate to Proxy → HTTP History 2️⃣ Locate the request that is currently using HTTP/2. 3️⃣ Send the Request to Repeater 4️⃣ In the Repeater tab, open the "Inspector" panel → Request Attributes → Protocol 5️⃣ Change HTTP Version to HTTP/1.1 6️⃣ Click "Send" in Repeater. If successful, you should receive a valid response, confirming the server accepts HTTP/1.1. And that's it! You've just downgraded the HTTP protocol and confirmed that the frontend server accepts HTTP/1.1! 🥳 You are now ready to smuggle requests! If you want to learn how to exploit this, we've got a Web Academy Lab you need to check out: Thanks for reading! #requestsmuggling #cybersecurity #BurpSuite #hacking #infosec

How email recovery is verified on the network: A new SMTP gateway forwards an email to a canister, which checks the DKIM signature that email servers already attach. To get the public key it uses a root of trust: DNSSEC where supported, or DNS over HTTP via an HTTPS outcall. The gateway is not trusted. The canister does the verification. Set it up at

Blockchain data quality used to be about consensus. Multiple providers, same output, trust the agreement. That's evolving. The future is verification: cryptographic proof of data from the block level up, with a full audit trail built in. BK joined the Crypto's Toughest Data Problems (and how to solve them) panel discussion at the Blockworks Digital Asset Summit to talk about where that's heading.

Your blockchain can't talk to the outside world. But the outside world needs to talk to it. One provider goes down = your urgent transaction is stuck. One API error = is that really $1M USDC or just $1? This is fine for your $10 memecoin. But customer funds? The Internet Computer solves this problem, watch the full episode here:

AI Mode is our most powerful AI Search but... how does it work? 🔍 Using a "query fan out" technique, Search calls on Gemini to break a query into subtopics. Then it issues multiple, concurrent searches and taps into real-time data to generate the most helpful response.

💾 Vibe coded an entire dial-up TCP/IP stack for my TUI OS to get to the internet so it can now too browse the web It uses the same ISP as does which is (a real dial up provider) and then the browser routes you to my HTTP-proxy (because it doesn't support HTTPS yet) so you can open modern websites with it WebSocket → HDLC framing → PPP → LCP/EAP/IPCP → IPv4 → UDP → DNS (one round trip) → IPv4 → TCP (3-way handshake) → HTTP/1.0 → HTTP reverse proxy → HTML parse → render in OS browser -> render in your browser Also we have some techno in the music player now (not good yet) VERY GEEKY 🤓
