Ledger Warns BIP-110 Has No Fork and No Replay Protection
Ledger has alerted users about the BIP-110 fork, stating that this soft fork lacks replay protection, which may result in the same number of coins existing on the new chain.
Ledger devices automatically support the relevant signatures, but it is advised not to claim coins on the BIP-110 chain before adding a replay protection mechanism, as signing on the BIP-110 chain may jeopardize the security of the main chain BTC.
The lack of replay protection in the fork increases the risk of double spending, and users should operate their assets cautiously under event-driven circumstances. Those who follow security advice will benefit, while reckless operators will face pressure.

BIP-110, as a temporary data-limiting soft fork, triggers node forks when there is insufficient hash power. Due to its design lacking built-in replay protection, signed transactions may be valid on both chains simultaneously, shifting the focus from consensus changes to actual asset security risks.
The resources and security advice are concentrated on clear warnings from hardware wallet manufacturers, aimed at preventing users from inadvertently exposing their main chain private keys or triggering replays by claiming a few chain coins, leading to potential financial losses.
This is similar to the replay protection controversies in historical forks like Bitcoin Cash; currently, we are in the early stages of chain splits following the opening of the BIP-110 mandatory signaling window, with user operation security being the primary concern.
Essentially, this represents the security cost of a technical alternative: if a soft fork evolves into an actual fork without replay protection, the mechanism relies on shared history and UTXOs, allowing the same signature to be utilized by both chains, amplifying asset risks.

Forks without replay protection are breeding grounds for asset double spending.
Security advice from hardware wallets is often more reliable than on-chain narratives.
Before claiming new chain coins, one must first confirm the protection mechanism.
