The estimated operating costs were high, so that the network fork not only reduced the power of the protocol, but also generated losses on both sides who are debating the true "vision" of Satoshi Nakamoto, creator of Bitcoin (BTC).
Given the hostilities of Bitcoin SV, developers of Bitcoin ABC have introduced changes to introduce checkpoints every 10 blocks created in the chain, to check the status of transactions and the size of their blocks.
The goal is to prevent block reorganization attacks (reorgs), after constant threats that the BCH network received after the bifurcation. However, and also according to BitMEX, although this reduces the risk of rewriting the chain by attackers, introduces a new vector of attack that malicious miners can exploit.
In this case, the attacker could extract a hidden parallel string from this point. Entering your chain after the tenth block, Some minors on BCH's main network could start by undermining the malicious block, while others would exploit the honest block, which would make sure that the malicious chain is considered valid because it is the longest.
Although the price of both currencies is currently rising, it should be remembered that before the division, each BCH had a price of $ 422, while it now stands at 210 and the BCHSV at $ 119.
