The write-ahead log (WAL) is both how databases commit fast and how they safely recover from crashes.

Outside of B-trees, it's probably the most important structure in Postgres and MySQL.

(it's called the "redo log" in MySQL-land)

Me and @M3talDrag0n decided to compete against each other this time instead of joining up as a team and we accidentally tied for the 1st place 😅. Looking forward to seeing our names much more often in top places on @cantinaxyz as a team 🚀.

Good job everyone who participated!

That’s it, @xyz_remedy CTF has ended. Absolutely enjoyed every minute of a competition with around 2,000 teams from which 600+ active, this is insane.

@ChainLight_io proved once again they’re absolutely brilliant at this game.

Huge thanks to everyone involved, the contributors for the awesome challenges and all the participants who made it so competitive 🫡

The biggest web3 @xyz_remedy CTF 2025 is over.

Congrats to @ChainLight_io, A-Team, and @Web3Kimchi for getting to the very top.

1800+ teams
600+ active participants
60+ teams to solve at least 2 tasks

Numbers are truly inspiring, it was thrilling and makes you constantly monitor the scoreboard.. thank you all for participating!

Lessons learned:
It was the first year we did this “discovery” CTF, there were a lot of variables and unknowns before we started.
Now that we have more information expect RCTF 2026 to be much more fun and refined.

Community contribution:
Is crucial... I want to thank everyone who contributed to this event: @osec_io @DecurityHQ @m4k2_0x and @TokemakXYZ @wintermute_t
All of this goes to you the web3 security community.
Hope we will see more contributions next year also.

Finally, we all can go to sleep.
