The SSL certificate for electrum.emzy.de:50002 has expired and has been replaced with a new X.509 v3 certificate using RSA 4096-bit.
If you use Sparrow Wallet, you may be asked to accept the new certificate on the next connection — just click OK. 😅
New cert, same Electrum server. 🧡⚡

Everyone contributes to Bitcoin in their own way.
Wiz & Associates has contributed for years as a network operator, providing DNS and other critical infrastructure for the community. We now propose to extend that operational role to the top-level of the Domain Name System 🚀
Today, ICANN just published the 2026 new gTLD applications! Wiz & Associates filed a community priority application for the .bitcoin TLD, on behalf of the people and organizations that run, build, and provide the infrastructure, software, and services of the Bitcoin network. 🧵

After 7 years leading Foundry, I have decided to step down as CEO. Building this company from an idea into the operator of the world's largest Bitcoin mining pool has been a true honor, and I did not do it alone. I have had the privilege of working alongside an incredible group of individuals over the years who built a world-class company. I will remain with Foundry for the next six months as a strategic advisor to support the transition and CEO search.
Thank you to everyone @FoundryServices and our partners for the trust and support over the years. I am looking forward taking a break and spending time with my family.
Today we announced that @colyermike is stepping down as CEO of Foundry after 7 years. Mike built Foundry from 1 employee into the operator of the world's largest Bitcoin mining pool. He will remain with Foundry for six months as a strategic advisor to support the transition.

Opus 5.5 (released 1 hour ago) is so outdated, everyone is using GPT6.0 Sol (releases 5 minutes ago) and you’ll be part of the permanent underclass if you haven’t already pivoted by the time you’re reading this tweet.

I used to try to convince people to hold Bitcoin for reasons outside of number go up.
Freedom, personal responsibility. Things like that.
Turns out a lot of people don't want freedom, and they hate being responsible for their actions.
But they all love making more money. 😂

Dear BitMEX Users,
Today, we share with a very heavy heart that BitMEX exchange will shut down its operations, effective 23 September 2026 at 04:00:00 UTC.
The owner and operator of BitMEX, HDR Global Trading Limited, has made the difficult decision to close operations following a strategic review of the business.
It may not look the same today, but we are proud of our 11+ year legacy and the role we played in shaping the crypto industry. We invented the 100x leverage perpetual swap, which for most of you, was the first step to your crypto trading journey. It is now the most traded financial product in the crypto industry, adopted by thousands of users and exchanges. And we remain proud of our robust security infrastructure, which has allowed us to maintain a flawless track record of 0 customer funds lost to hacks in our entire operating history.
We want to reassure you that your assets remain fully safe and under your control during this transition period. This announcement is just to give enough time to ensure a smooth withdrawal process for everyone.
From today we strongly encourage all users to close their positions and withdraw their funds as soon as convenient. For more details on the full process, please read our blog: bitmex.com/blog/bitmex-closu…
BitMEX was once home to some of the greatest traders today. Our team has dedicated tremendous effort and passion into building the platform into what it is, and we are glad to have reached some of you during your time with us. To everyone who has traded, supported, and grown alongside us - thank you for your trust over the last 11 years.
The BitMEX Team
