OpenSig

Introducing OpenSig. Privacy-first IP protection for the digital age. Timestamp your creative work on blockchain before you share it. Files never leave your device. Beta is live now on iOS & Android. First 3 timestamps free. → opensig.net

Copyright protects ownership. It doesn't protect priority. Those are two completely different things and almost nobody knows the difference until they're in a room with a lawyer.

A photographer licenses an image to a brand. The brand uses it beyond the agreed scope. The photographer complains. The brand says the license was broader, and points to a version of the contract they claim is correct. The photographer has emails, the brand has a different set of emails. Without a timestamped record of exactly which version of the agreement existed at exactly which moment, there is no clean resolution. This happens every week. Most of the time nobody talks about it.

We're genuinely trying to understand how different professionals handle this: 1. If you're a lawyer, how do you advise clients to document digital IP before a dispute? 2. If you're a researcher, what's your current protocol for proving when a finding was first documented? 3. If you're a creator, what does your paper trail actually look like? Sharing what actually works, not what should work.

The most important decision we made building OpenSig is that: Your file never touches our servers. Before anything reaches the blockchain, your file is hashed locally on your device. What we receive is a fingerprint mathematically unique to your file. We cannot read your file. We cannot share it. We cannot lose it. Most "secure" tools ask you to trust them with your data. We built it so you don't have to trust us at all.

The Anthropic source code leak exposed 1,900 typescript files through a forgotten source map. Trade secrecy failed in a single deployment mistake. This is why the only IP protection that survives human error is one that doesn't depend on secrecy at all. You timestamp the proof of existence. The work stays private. The proof is public and permanent. No deployment mistake can undo a blockchain timestamp.

@aakashgupta then what's the solution?

YouTube's copyright system is so broken that the people who steal your content can legally take YOUR video down. Here's what happened. La7, an Italian broadcaster, used footage from Nvidia's DLSS 5 announcement in their programming. Then Content ID scanned the internet and matched La7's upload as the "original." So when Nvidia's own video matched against La7's copy, YouTube's automated system sided with the copier over the creator. The system doesn't verify ownership. It verifies who uploaded first to the Content ID database. That's a completely different thing. Whoever registers the fingerprint first becomes the "rights holder" in YouTube's eyes, regardless of who actually made the content. This is the same architecture that lets music labels claim royalties on songs they don't own, lets random accounts claim game trailers they had nothing to do with, and lets bad actors weaponize takedowns against competitors. The cost of filing a false claim is near zero. The cost of fighting one is days of lost revenue and a channel in limbo. YouTube processes 500+ hours of video every minute. They built Content ID to automate copyright enforcement at that scale. But automation without verification creates a system where the incentives reward abuse. You can claim anything, face no penalty if you're wrong, and the burden of proof falls entirely on the actual creator. When your copyright system can be used to take down the original creator's own content, you haven't built copyright protection. You've built a weapon anyone can point in any direction.

What works is a cryptographic hash of your file anchored to a public blockchain. Tamper-proof. No platform controls it. Created in seconds. That's what we're building at OpenSig.

Cloud save timestamps are controlled by the platform. The platform can edit, delete, or lose them. You're trusting a corporation with your proof. 3. Social media post. Somehow better at least it's public. But the platform controls it. X has has suspended millions of posts. Instagram has lost metadata. Still not yours.

4 ways people try to prove they created something first and why 3 of them fail: 1. Email to yourself. Editable. No independent verification. A judge will not care. Your email provider controls that record, not you. 2. Cloud save timestamps (Google Drive, Dropbox, iCloud).🧵

Truly, taste is the one thing AI can't replicate. But here's the adjacent problem: When AI can generate a near-identical version of your original work within hours, taste alone doesn't protect you. You need prove of when the version of that your taste existed. That's exactly what we are building on @0xPolygon.

@oliviamccabe72 @ScriptShield This is the oldest and the common way most people do it. But the truth is: your email provider controls that record

@ScriptShield I email it to myself at the end of every day,

I've been thinking a lot recently about interacting with authors on here who write in very different genres to my own. I will be honest, I usually steer well clear of horror and erotica. They are not genres I like to read. But that doesn't mean I don't have a lot to learn from the horror and erotica writers of this world. My current WIP is contemporary women's fiction, but that doesn't mean I only want to speak to people who write in this genre. I love to read historic fiction, mysteries, romance, fantasy and adventure. If you write in any of these genres, I may well be interested in reading your books. Regardless of genre, I am interested in connecting with you as a writer, because at the end of the day, as we all stare at a blank page, wondering what words will topple out, there is a whole lot more that unites us than divides us. If you are a writer, then I would love to hear about your day. #writingcommunity #amwriting #writerslife

This doesn't mean IP protection is useless. It shows secrecy alone doesn't work anymore. In the current ai world, anything can be leaked, replicated, or rebuilt faster than ever. The advantage is no longer in trying to hide your work, it's being able to prove it. > who created it > when it existed > and what came first You can’t stop copying, but you can make authorship undeniable.

@yourealazyfvck Happy Easter, David

Wishing you, your family, and those you love a Happy Easter. Whatever you’re doing today, I hope you’re somewhere good, with people you love. For those who don’t know, I believe in God, and when I was younger, I had gone back and forth with my faith until about 5-6 years ago. And I believe that Easter is a very powerful reminder of that as we come into the second quarter of the year. No matter how far you’ve fallen, no matter how dark things have gotten, renewal & your own version of a “rebirth” is always available. The slate can always be wiped clean. I always say that in order to become the person you want to be, you have to rise from the ashes like a phoenix. I think about that a lot and I’ve needed that reminder more times than I can count. There have been many seasons and times in my life where I should have been broken and defeated. Where most people would have walked away with their tail between their legs and condemned themselves to that. And that’s something to be grateful for that holidays like Easter remind you of, which is that something bigger than you kept you standing when you had no business still being on your feet and making it through. Easter Sunday is a reminder of the unshakeable belief that God gives you when you walk with him in your corner. So however you’re spending today, enjoy it. Happy Easter my friends. - David

Before digital tools, writers used to mail themselves manuscripts. The sealed, postmarked envelope unopened, became informal proof that the work existed by that date. It wasn't legally bulletproof. But it was better than nothing, and it was self-sovereign: No third party controlled the record. The instinct was right. The infrastructure was the limitation. A cryptographic timestamp on a public blockchain is the same instinct, with infrastructure that actually holds.

Provable priority is a harder problem than most people realize, not technically, but socially. Technology can create a tamper-proof timestamp. What technology can't do is make that timestamp legible to the person on the other side of a dispute. The gap between someone has a verifiable record and "that record is accepted as evidence" depends on context, legal jurisdiction, the nature of the dispute, who's interpreting the record. The tool exists. But the job it solves best depends on who's holding it and what they're trying to prove.

How cryptographic timestamping works: You take a file. Before uploading it anywhere, the file is converted into a unique fingerprint on your device. The fingerprint, not the file, is recorded on a public blockchain. In our case, we are using @0xPolygon. So you end up with a verifiable record that a file with that exact content existed at that exact moment. What you don't end up with is your file on someone else's server, not even on ours. The privacy property here is as important as the timestamp. Your content never leaves your device. Only the proof does.

The most expensive four words in professional life: > "That's not what we agreed." Most disputes don't involve fraud. They involve two people who genuinely remember the same conversation differently, and no record either of them can point to. The gap between what was agreed and what can be proven is where professional relationships break down.

@devjoshstevens @Polymarket x.com/OpenSigLabs/st… this is the missing link

Excited to join @Polymarket as VP of Engineering. I haven’t seen a hungrier team in my career, the talent density here is insane. We’re building the future of how people understand the world. What should we build next? What’s broken? What’s missing? Drop it below. P.s we are hiring world class people in NYC DMs open

The blockchain use case that gets the least attention is: - Timestamping The oldest and simplest thing you can do with an immutable ledger is record that a piece of data existed at a specific point in time, in a way no single party controls. > No platform can edit > No company can revoke The record exists independent of whoever created it. For anyone who needs to prove they made something first, that property is genuinely useful. And this is what we are bringing on @0xPolygon.
