so, One of Bitcoin’s weirdest engineering tricks! 🎩✨ Bitcoin did increase the block size with SegWit in 2017 but they can’t officially call it that because of backward compatibility with old nodes. 👉 It’s still called a "1 MB block" for old nodes. 👉 It actually stores up to ~4 MB of data. 👉 This works because Bitcoin Core changed how block space is "counted" (Weight Units instead of bytes).
