…Deleting the .pem alone won't hold, since --fresh regenerates it

Mozilla says it isn’t removing emSign Root CA - G1 for now, so G1 will still show up

[Irene @_RulesPlayer]

Mozilla has blocked the compromised eMudhra intermediates through OneCRL and removed the emSign ECC Root CA - G3 from NSS, after the intermediate keys turned out to be trivially recoverable. The bug is here: https://t.co/nlDxoPXEA2

[International Cyber Digest @IntCyberDigest]

‼️ BREAKING: The private keys of 8 certificates from Indian certificate authority eMudhra were compromised, Mozilla says. Firefox blocked them within 3 hours.

Each key should be a 116-digit number, but one was just 4.

Anyone can guess them and forge HTTPS certs for any website.

[Irene @_RulesPlayer]

…To fix it, rebuild on a base image that has removed G3, or exclude it yourself

On Alpine I used
sed -i 's#^mozilla/emSign_ECC_Root_CA_-_G3.crt#!&#' /etc/ca-certificates.conf && update-ca-certificates --fresh

then re-ran the grep to confirm

One of the things we explored was raw transactions.

We worked with:

Transaction IDs
UTXOs
Transaction inputs
Transaction outputs
Bitcoin addresses
BTC amounts

Seeing these pieces come together makes Bitcoin transactions much easier to understand.

The end of a program is not always the end of the story.

Months after the 2026 ₿OSS Challenge, @abeeujah, @jolah99, Winterrdog, @tech_lateef, @JunaidAaliyah, @dev_useee, @chukwuxdike, @Su_Githaiga, @Its_nkathake, @_RulesPlayer and @_ceceji are still finding different ways to contribute to Bitcoin open source.

Some are reviewing PRs and contributing to established projects. Others are building new applications, improving developer tools, exploring Lightning infrastructure, mentoring the next generation of developers and deepening their understanding of Bitcoin’s technology.

[BitDevs Uyo @BitDevsUyo]

Most people use Bitcoin.

Few understand how it actually works.

At BitDevs Uyo, we're here to bridge that gap.

Every meetup is an opportunity to explore the technical side of Bitcoin—from cryptography and consensus to scripts, wallets, and the Lightning Network.

In 2026, @tando_me makes it possible to live on Bitcoin Kenya. They are now combining M-Pesa and Bitcoin's Lightning Addresses to unlock that for 40 million Kenyans 🔥

Emceed the @Bitnob_official Developers Meetup @the_buidl last week 🥹

A few months ago during the @SatSisterCircle mentorship program, I told @_RulesPlayer I wanted to improve my public speaking skills.

Now we’re here 😌
I’m open to more speaking and hosting opportunities.
