blockchain – Compelled fork of older, low issue blocks

0
42


Let’s assume most important chain (A) top is 1000 and the issue adjustment is 50 blocks. At top 450, the issue could be very small. By modifying timestamp of blocks 450-500, I mine a fork (B) such that at top 500 to 600 the chainWork is increased than A on the similar top.

A brand new peer needs to sync with me. I ship B. At top 500 to 600, the peer chooses B and saves A as a fork. Given an extended sufficient pressured forking of A, is it potential for the peer to surrender on A?

If the consumer by no means offers up on a fork, does this open it to fork chain spam assaults?
