Forks & Reorgs
Race of branches, and why confirmations matter.
Watch honest vs adversarial branches grow, see forks appear, and watch reorgs orphan blocks when the longer chain wins.
PoW forks Reorgs Confirmations Network delay
Quick guide
- Pick honest hashpower and delay; Initialize to reset both branches.
- Mine 1 block or Auto-mine to let branches grow; longer chain becomes canonical.
- Orphaned blocks appear hollow; Height and Active branch reflect the current tip.
Controls
Hashrate & delay
Lower honest hash or raise delay to see more forks; confirmations make reorgs less likely to affect you.
Chain race
Height: 0 Active: A Reorgs: 0
Blue = honest branch A, Orange = adversarial branch B. Hollow blocks are orphaned after a reorg; the longest chain is canonical.
Fork flurries, reorg ripples, and why depth saves you
- Initialize to reset both branches to height 0.
- Mine 1 block to step once, or Auto-mine to let probability pick A vs B each round.
- Active shows which chain is longer; Reorgs count bumps when the winner switches.
