Concerned about your hardware wallet after the recent Coldcard attack?
My new Manual BIP39 Seed Generation Kit guides you through the process of creating a BIP39 seed phrase using coin flips, dice rolls, or other physical forms of entropy.

One of the holy grails of crypto is building dApps ready for the mainstream.
Private-key management and the complexity of crypto have kept everyday users away, limiting adoption to custodial exchanges and people sufficiently motivated to endure the UX.

The user experiences an ordinary mobile application.
Underneath, they control their own account, authorise their own transactions and interact directly with an open network.

OpenSig demonstrates an architecture in which ordinary users can directly own and operate an on-chain account without first becoming “crypto users.”
That, to me, is what mainstream crypto adoption is likely to look like.

Beautifully and sensitively made, and very compelling. Well worth a watch.
Finding Satoshi is one of the most well-produced Bitcoin documentaries I've had the pleasure of watching.
I learned a few things and so will you... it's available today at findingsatoshi.com/

All of this is live! it's early and slow. many of the demos above are sped up/edited, but we can't wait to see what you think. Try it yourself at flipbook.page (5/5)
On-chain decentralised accounts fix this:
❝Google and Microsoft effectively felt they were forced to completely disable all [the head of the ICCs] accounts and all his access to everything, leaving Europeans thinking: 'Well could this happen to us?'❞

Timestamping your work on the blockchain as a regular part of the creative workflow provides an undeniable record of your intellectual property.
How do investigative journalists prove their photos are not AI generated?
Or record an audit trail of notes that demonstrate a timeline of evidence?
The blockchain is a constant timestamped record on which to anchor events and documents.
OpenSig is the app with which to do it
I've been using TheGraph for probably 3 years now, first for Seedling and now for OpenSig. It's a quality service for querying blockchain event data with GQL.
Sometimes it can fall behind the blockchain by 10 minutes or so, but hopefully that will improve as usage picks up.
OpenSig took a lot of effort behind the scenes to get right. Biconomy’s discord support was fast, reliable, and thoughtful throughout. A credit to the team.
Huge respect to the @OpenSigLabs team for shipping this.
They delivered a real, mass‑market signing app where users get gasless, self‑custodial proofs without ever dealing with wallets or crypto concepts directly, which is incredibly hard to execute.
We’re proud that Nexus smart accounts and our bundler infrastructure could support this, and grateful for the trust. 🙏

Tomorrow's World was one of my favourite programmes as a kid. It reviewed the cutting edge of home technology.
Astonishing how much tech has changed in 40 years yet the cutting edge seems just as scrappy and frustratingly slow now as it did then.

Verifying a file on OpenSig takes just a few seconds.
Immutable proof of possession.

Copyright, as the name suggests, gives you the right of ownership over your work. That's all well and good, but how do you prove you created it?
OpenSig anchors your work to your identity on a specific date using cryptographic proof. No bullshit, just math.
Don't trust, verify.
People often treat I created this and I own the copyright as the same claim.
They aren’t.
Copyright is a legal right that arises automatically when you create an original work.
But proving when you created it or that a specific file existed in a specific form is a separate question.
That’s where proof of creation matters.
OpenSig doesn’t replace copyright.
It gives you independently verifiable evidence of:
- when a file existed
- what its exact contents were
- who held it at that point in time
This strengthens authorship claims, clarifies timelines, and reduces ambiguity in disputes.
Copyright is the right.
Proof of creation is the evidence.
