Most online compression tools work on Server-Side processing. This means:

1. You upload your image to their server

2. Their backend processes it

3. They send the optimized version back

4. Your file may stay on their infrastructure (temporarily or longer)

But technically speaking:

• Your file leaves your machine

• It touches someone else s server

• It may be logged, cached, or stored

• You usually don t see what happens behind the scenes

VeilChain is a Zig-based blockchain node. Today it already includes a functional Proof-of-Work loop (Blake3-backed header hashing), an ASERT-like difficulty retargeting hook, chain append/validation checks, and a local multi-node testnet runner you can launch from the CLI (status, mine, testnet). It also ships early ledger primitives (note commitment, nullifier derivation + nullifier set, and a commitment tree) as foundations for the later shielded transaction + proof system work.

What s implemented right now:

• Consensus foundation (prototype): PoW header hashing + meetsTarget() and a working mining loop

• Chain logic: genesis + sequential append validation (prev_hash, height, pow target)

• Difficulty retargeting (prototype): ASERT-like target adjustment utility used by the chain

• Testnet runner: local multi-node simulation that mines blocks across nodes

• Ledger primitives (foundation): note commitments, nullifier derivation/set, simple commitment tree root

Why this matters:
If you re building toward post-quantum and shielded-chain designs, you need an execution layer that s deterministic and testable. VeilChain provides a real, runnable base in Zig so the next milestones (p2p connectivity, persistence, shielded transaction circuit/proofs, full RPC surface) can be added incrementally without losing correctness.

Hey everyone Andrew here, founder of Koalr. We just launched.

Koalr scores every pull request 0 100 for production risk before it ships. It uses 36 research based signals things like file change blast radius, author expertise drift, CODEOWNERS violations, CI history, and time-of-week patterns to flag risky deploys before they become 2am incidents.

It connects to GitHub in minutes, no code access needed we only read metadata.

Hey everyone, I m one of the founders behind @Synvolv

Wanted to post this here a bit more openly, not really as a promo thing, but because this problem has been sitting with me for a while.

I'm a solo female traveler who's been exploring India for 5+ years. Every time I planned a trip, the safety advice was always the same: "Be careful." "Trust your gut." "Delhi is dangerous for women."

Last year I was planning a solo trip and got so frustrated with vague warnings that I almost canceled. Then I realized - these articles aren't written by people who've actually solo traveled there recently. They're just recycling generic advice.

Hey Hunters! We re tired of "Managed WP" being a synonym for "Slow WP." Meet SyndockEngine.

Click "Deploy" and in 90 seconds you get a production-ready site with an "A" grade on GTmetrix. No plugins required.

Hello fellow managers and developers,

We have built and launched kibbar.com for the productivity of launched and in-development products.

• We help in tracking the reviews and sentiments of the users on the Play Store and App Store.

• And for development, we provide the distribution platform for the android and iOS development so that testing apps can be distributed without any hassle of store setup.

• There is a Short URL service that provides detailed analytics of the Short URL created.

  

We re getting close to launching Provoke on Product Hunt.

Over the last week I ve shared a bit about the problem, the workspace, the marketplace, and recording.

Over the next two weeks I ll start sharing more of the ecosystem:

• calendar

• email workflows

• media generation

• project management

• and how all of it fits together
