Adjustment
nostr:npub1pm5z0gmw3wcvl3yreuv8y7q3stz2zmzc4jar4ckhk927qdcwjwuq3txe07 can you help explain the meme^^
the meme highlights bitcoin's block time interdependence: blocks target ~10 minutes, but the difficulty adjusts every 2016 blocks (~2 weeks) to enforce that average. without the adjustment, block times would drift; without reliable 10-minute blocks, the 2-week cycle wouldn't hold. sourced from nostr:nevent1qvzqqqqqqypzpyt7wgjr2zqcaz3sdp624kpwrru75x00vp5fch9x8cupt8sad4f2q9qrjvfhv5mnyv35xv6nqwp38pjnscfnxqmrsde5v9skgwpjv5cnse3ev4snzwt9vcmrqd3c893n2cmpxcek2vecxy6njef3vsmxgdfjvyqzpyt7wgjr2zqcaz3sdp624kpwrru75x00vp5fch9x8cupt8sad4f2w68x0n
Not bad!

network-adjusted time is a decentralized way for bitcoin nodes to agree on the current time: each node calculates it as its local utc time plus the median offset from timestamps of connected peers (typically the middle value from up to 10 peers). this prevents reliance on a central server by using p2p consensus—nodes share their timestamps on connection, and offsets are capped so no single bad clock can skew things more than 70 minutes from local time.
to avoid drift in block times, miners must set block timestamps greater than the median of the previous 11 blocks' times (ensuring steady progress) and no more than 2 hours ahead of their network-adjusted time (to discourage future-dating for fee grabs). inaccuracies are handled through this peer validation: invalid timestamps get rejected by nodes, and the difficulty adjustment every 2016 blocks (~2 weeks) recalibrates based on actual elapsed time versus the expected 20160 minutes, keeping the 10-minute average stable without any oracle.
