Your ideas are your most valuable assets. Defend them with spArxx.io. Musician, writer, inventor, artist, designer, photographer, filmmaker ... if you made it, it's worth protecting. spArxx.io timestamps your work in seconds, creating permanent "Proof of Existence": the evidence you need to defend what's yours. How We Protect You: Private Digital "Fingerprinting": We capture the unique DNA of your idea using advanced cryptographic hashing. Your original files never leave your device, ensuring absolute "Zero-Knowledge" privacy. "Zero-Knowledge" means that we don't know the contents of your file(s) ... our secure hashing only lifts a unique digital "fingerprint" from your electronic file locally, without requiring an upload. Immutable Proof of Existence: We take your digitized idea's "fingerprint" hash, and permanently anchor it to the blockchain. This creates an unalterable, time-stamped record proving exactly when your original creative work was born. Ironclad Certification: Instantly generate an immutable PDF certificate, and a hosted transaction Receipt, that serve as tangible, portable proof of your creative work. No Subscriptions. PAYG (Pay As You Go): To keep your costs low and your convenience high, we use a Vending Machine business model. You only pay for spArks credits as you need them, and your timestamps are generated for you in real time, as you wait. Frictionless Onboarding: Start immediately. No email, no password, and no credit card required to begin. Download the app and receive 50 free "spArks" to generate your first timestamps instantly. Once you are ready, easily claim your anonymous account to securely sync your Digital Evidence Locker across all your devices, by providing only an email address and password. No credit card required.

About

OpenPacketLoss

Features
Read full description

OpenPacketLoss-Server is a lightweight utility that transforms your computer into a dedicated network testing endpoint. By hosting the server on your own hardware, you can measure the precise quality of the connection between two points on your network, eliminating the unpredictable variables of the public internet. How to Use It Run the Server: Launch the app on a stable PC or laptop—this becomes your "target" device. Connect the Client: Use any OpenPacketLoss client on a different device (such as a phone, tablet, or another PC). Troubleshoot: Start the test to view real-time packet loss, jitter, and latency. Why Run Your Own Server? Testing against a server you control allows you to isolate your hardware. You can instantly determine if connection drops are caused by faulty cables, weak Wi-Fi, or router congestion, or if the issue is actually with your Internet Service Provider (ISP).
