FastBreak

FastBreak cuts block-breaking time: a block that takes an honest player seconds vanishes in a fraction of one. And that time is strictly defined in Minecraft — by the tool and its material, Efficiency, Haste and Mining Fatigue, whether the player stands on the ground and whether they're underwater.

The payoff is direct: ore, obsidian, stone and wood come in several times faster. On survival that's extra resources, money in the economy and spots on the leaderboards; in BedWars it's end stone or obsidian bed defence chewed through in seconds; on anarchy it's a quick tunnel under someone's base. An honest player with the same pickaxe loses the race without knowing why.

• Cracks on the block don't get through all their stages — the block just disappears
• Obsidian and end stone break faster than for others with the same pickaxe and enchantments
• Underwater without Aqua Affinity, or mid-jump, the player mines as fast as standing on the ground
• A tunnel advances at a steady high speed with no gaps between blocks

The server sees when a player started digging a block and when they finished, and knows how long it should take: block hardness, tool, Efficiency, Haste, Mining Fatigue, water, ground underfoot. A block broken noticeably early is evidence. FastBreak also often removes the short pause the vanilla client keeps after every broken block.

Ping blurs the line: the start packet is delayed, the finish arrives on time, and an honest block looks broken faster. So the check needs a tolerance and dozens of blocks. Instant breaking alone is normal: grass and flowers break at once, and with Efficiency V plus Haste II even stone is instamined.
