Selfish Mining

Definition

Selfish mining is an attack strategy where miners withhold discovered blocks, releasing them strategically to waste honest miners' work. By timing releases carefully, selfish miners can earn disproportionate rewards—more than their fair share of hashrate would earn.

Technical Explanation

Normal mining: find block, broadcast immediately. Selfish mining: find block, keep secret, continue mining. When honest miners find a block, release your hidden block to create a race. With network advantage, your chain wins; honest work is wasted.

Profitability depends on: attacker hashrate fraction (works with less than 50%), network connectivity (fast propagation helps attackers), and blockchain tie-breaking rules. Mitigations include timestamp requirements and randomized tie-breaking.

SynX Relevance

SynX's consensus design includes considerations for selfish mining resistance. Decentralized mining through CPU-friendly algorithms makes selfish mining harder—no entity easily accumulates sufficient hashrate to profit from the strategy.

Frequently Asked Questions

Is selfish mining common?
Rarely observed—requires significant hashrate and risks detection/reputation damage.
Can selfish mining steal funds?
No—it earns extra mining rewards, not others' coins. Still harmful to network fairness.
How is selfish mining detected?
Unusual orphan block patterns, timing analysis, and statistical deviation from expected rewards.
