Same story if you control 1% of hash power. Anyone can ignore any block, but you can't completely block a transaction unless you prevent it from being included

Same story if you control 1% of hash power. Anyone can ignore any block, but you can't completely block a transaction unless you prevent it from being included in ANY block. Even if 90% of the hash power is blocking your transactions it just means it takes 10x longer for your transaction to go through.
- Dylan16807 9y agoThis is not ignoring transactions, this is ignoring any block that contains those transactions. You make your own pure chain that's longer, and everyone else uses it too because it's longer. If someone else mines a block then such a transaction can temporarily get a confirmation or two, but the 90% steamroller will come by and quickly reduce it back to 0 confirmations on the longest chain. If someone with 1% hash power ignores certain blocks, they make a chain that's totally irrelevant in their own corner. If someone with 60% hash power does it, they win.
