Ghostty is now indisputably the fastest terminal emulator at IO throughput, by a very large margin. On ASCII, Unicode, and CSI tests, Ghostty is more than 2x (double!) faster than any other leading "fast" terminal. These changes are directly in libghostty, too, so everyone wins.
`time cat 150MB_ascii.txt`:
- Ghostty nightly: 575ms
- Ghostty 1.3.2: 1.5sec
- Alacritty: 1.2sec
- Kitty: 1.7sec
- Warp: 3.8sec
- iTerm2, Terminal: stopped after 60s
`time cat 150MB_unicode.txt` (mixed languages):
- Ghostty nightly: 536ms
- Ghostty 1.3.2: 1.22sec
- Alacritty: 1.05s
- Kitty: 1.35s
- Warp: 3.4s
- iTerm2, Terminal: stopped after 60s
`DOOM-Fire-Zig` (an IO test):
- Ghostty nightly: 842fps
- Ghostty 1.3.2: 532fps
- Kitty: 485fps
- Alacritty: 593fps
- Warp: 577fps
- iTerm2, Terminal: 60fps (yes, 60)
To quickly address the "cat speed doesn't matter" naysayers: this is a direct test of how many bytes/second you can push through a terminal. It doesn't cover just "read big file" but also "how much can a TUI do". The tests above test various shapes of inputs (plain ascii, unicode/wide chars, csi-heavy loads, etc.). IO throughput is incredibly important.
Most of these improvements apply to libghostty-vt consumers too, so any libghostty-based terminals will instantly see huge throughput improvements by simply upgrading (ABI compatible).
I'll cover the exact improvements in a blog post in the future. These results are the result of 6 separate optimizations.

I strongly believe there are entire companies right now under heavy AI psychosis and its impossible to have rational conversations about it with them. I can't name any specific people because they include personal friends I deeply respect, but I worry about how this plays out.
I lived through the great MTBF vs MTTR (mean-time-between-failure vs. mean-time-to-recovery) reckoning of infrastructure during the transition to cloud and cloud automation. All those arguments are rearing their ugly heads again but now its... the whole software development industry (maybe the whole world, really).
It's frightening, because the psychosis folks operate under an almost absolute "MTTR is all you need" mentality: "its fine to ship bugs because the agents will fix them so quickly and at a scale humans can't do!" We learned in infrastructure that MTTR is great but you can't yeet resilient systems entirely.
The main issue is I don't even know how to bring this up to people I know personally, because bringing this topic up leads to immediately dismissals like "no no, it has full test coverage" or "bug reports are going down" or something, which just don't paint the whole picture.
We already learned this lesson once in infrastructure: you can automate yourself into a very resilient catastrophe machine. Systems can appear healthy by local metrics while globally becoming incomprehensible. Bug reports can go down while latent risk explodes. Test coverage can rise while semantic understanding falls. Changes happens so fast that nobody notices the underlying architecture decaying.
I worry.

Când 200 de magistrați spun că este o problemă de integritate în sistemul de justiție, lucrurile sunt foarte serioase.
Invit toți magistrații care vor să reclame probleme în sistemul de justiție la o discuție fără limită de timp luni, 22 decembrie, începând cu ora 10:00. Aștept înscrieri la adresa [email protected].
Până joi, 18 decembrie, ora 24:00, vă invit să îmi trimiteți materiale, asumate nominal sau neasumate nominal, la adresa [email protected].
În zilele de vineri, sâmbătă și duminică vom avea timp să citim toate materialele pe care ni le trimiteți.
(În toată săptămâna 15–19 decembrie sunt plecat din țară pentru formate multilaterale și vizite bilaterale confirmate cu mult timp înainte.)

Am văzut cap-coadă documentarul Recorder despre justiție. Cel mai simplu este să ne revoltăm, încă o dată, și să aruncăm vina generic. Mai greu este chiar să rezolvăm problemele din justiție.
În primul rând, felicitări realizatorilor, care aduc în dezbaterea publică, într-un mod accesibil publicului, probleme importante.
În al doilea rând, nu vreau să scuz în vreun fel politicul. Faptul că lupta anticorupție s-a redus dramatic are influență politică. Numirile procurorilor-șefi au fost politice. Societatea vorbește de mult de probleme în justiție fără să vedem, la nivelul Ministerului Justiției, voință de a intra cu adevărat în ele.
Dar soluția la problemele ridicate este tot în interiorul sistemului de justiție. Cazurile prezentate trebuie investigate și trebuie investigată mai ales recurența acestor cazuri. Iar persoanele vinovate trebuie pedepsite, însă tot de sistemul de justiție, și pe bază de probe. Pentru că materialul Recorder prezintă și fapte, care sunt clare, dar și opinii, care trebuie probate.
Cine strânge probele și cine face sesizările?
De ce nu avem încă un raport din interiorul sistemului de justiție, deși se vorbește de lucrurile astea de mult timp?
Câte sesizări s-au făcut din interiorul sistemului de justiție pe faptele de care vorbim?
Câte acțiuni în justiție s-au făcut pe faptele de care vorbim?
De ce sunt doar trei magistrați în activitate care au acceptat să vorbească deschis cu reporterii?
De ce nu a contracandidat-o nimeni pe Lia Savonea la conducerea Înaltei Curți?
Așa cum am spus, am început să lucrăm la un raport cu date despre problemele din sistemul de justiție. Discutăm cu magistrați. Îi invit pe toți magistrații să îmi scrie direct despre problemele pe care le întâmpină și îi asigur că voi citi personal ce îmi transmit.
Dar trebuie și o asumare în interiorul profesiei. Sunt convins că marea majoritate a magistraților sunt oameni serioși, de bună-credință.
E responsabilitatea lor, dincolo de dosarele curente, să se implice în rezolvarea problemelor profesiei lor. Și îi asigur, la rândul meu, de implicare și bună-credință pentru a aduce justiția acolo unde și-o doresc românii.

To our knowledge, this is a world premiere: integrating blockchain directly into day-to-day payment receipts.
Every purchase, tax breakdown, and transaction hash is transparently tracked on the blockchain—accessible via QR code, right on your receipt.
This level of detail—seamlessly linking real-world purchases with verifiable blockchain data—isn't just innovation; it's a revolution in payments.
From your burger to your taxes, every step is clear, accountable, and future-ready. Proud to bridge blockchain with mainstream commerce on @MultiversX !

Over 90% of validators have already upgraded and are ready for mainnet activation of the first implementation of the new economics, bringing higher APRs for users and validators.

The first milestone of the new economics model has now been fully shipped, and is going to be activated on the 2nd December.
After one month of public dialogue, an open governance phase with an overwhelmingly positive vote, the team has taken the time to implement and fully test the first economics module - staking v5
The mainnet release has now been announced publicly on Monday, with the activation to be done on 2nd of December.
This an important ralying milestone for the network.
But why does this matter, and for whom?
First, this is a direct call to activation for users and investors. The staking rewards for securing and investing in the network have nearly doubled. All things being equal, this is a great moment to take a stake in the network, and become an active participant.
Second, this is a direct call to participation for validators. The new competitive staking rewards, mean that validators can renew their offering for users they are serving all over the world. Competitive rewards, enables users to be served much better.
Third, this is a prep for builders. With the new rewards, there are two buckets being soon enabled. A first one for simple staking rewards, and a second one for new DEFI yield strategies. Thinking about how those can be used effectively, and how they can be employed to serve the network and users better, is a good starting point.
The work on the first economics module is now done, and the release is in full motion.
A great effort put in by the team, while working heavily on Supernova stabilization.
Users, investors, validators and builders get a fresh incentive to deploy capital.
For people that see the value of the network, this is a good moment to engage, fructify the opportunity, and become an active part of the economy.

This is a Big Turning Point.
Something which was never achieved, changing the engine in a running car on a sharded network.
Such scalability, finality, decentralisation and effectiveness was never achieved.
Running sub second finality and 100K TPS on low specification machines, which can run off grid as well.
This is MultiversX.
Battle of Nodes: The EGLD Turning Point
Today marks a fundamental shift.
It's a convergence point where every core participant of the MultiversX ecosystem steps into a new era together.
-----
Until now, our Battles were focused:
- Battle of Nodes sharpened protocol security.
- Battle of Yields validated application logic under real economic pressure.
But today’s launch is different, because Supernova brings all four pillars of the ecosystem onto the same field, at the same time, for the same mission.
-----
1. Protocol Team - Rewriting the Rules of Time
We are releasing the most groundbreaking upgrade in the history of MultiversX.
A re-engineered chronology. A redesigned consensus.
A leap from 6 seconds to 600 milliseconds, with a clear path toward 400ms and 200ms.
This is an entirely new foundation.
-----
2. Validators - Fortifying a New Battlefield
Supernova reshapes the core primitives, metrics, and behaviors validators rely on.
It requires new monitoring, new configs, new intuition.
Your role: ensure the chain can breathe, scale, and self-heal under unprecedented speed.
-----
3. Builders - Engineering the 10x Experience Layer
A new internal clock means a new execution rhythm.
Smart contracts, backends, and tools all must adapt
so users can feel the upgrade where it matters: UX, responsiveness, and trust.
This is your moment to future-proof your apps before mainnet hits hyperspeed.
-----
4. Ecosystem Users - The Force Multiplier
When protocol, validators, and builders synchronize, users receive the compounding value:
- smoother interactions
- faster confirmations
- richer applications
- and a network that feels alive.
Supernova becomes real only when all three groups work in harmony.
-----
Why This Battle Matters?
Supernova is not just an upgrade.
For me, it’s a network-wide coordination event, a clock reset for the entire ecosystem.
A shadow fork stress-tested by every actor.
A battlefield where assumptions break, where resilience is forged, and where the future mainnet takes its final shape.
-----
Each track plays a critical role:
- Protocol Integrity teams hunting vulnerabilities at the architecture level
- Infrastructure teams proving reliability under explosive load
- Validators benchmarking real-world finality under extreme conditions
- Builders migrating, debugging, and validating the new execution paradigm
- Guilds stress testing the network with the creativity and chaos only users can unleash
-----
This is where everything converges.
This is where Supernova becomes unstoppable.
An Open Call to All Stakeholders
If you are part of this ecosystem, this Battle needs you.
Your expertise. Your tools. Your creativity. Your pressure.
-----
Join your track. Rally your guild.
Coordinate with teams across the world.
Let’s break things. Fix them. Improve them.
And together prepare the Supernova mainnet for the moment it explodes into production.
-----
This is the most ambitious milestone MultiversX has ever attempted.
Let the Battle of Nodes begin.
Stronger. Faster. Together.
