Introduction
As Bitcoin approaches critical network updates, users often wonder: What happens to my bitcoins during a chain-split? If your bitcoins are secured by a hardware wallet like TREZOR, rest assured—they remain safe even in the event of a chain-split. This article explores potential scenarios, precautions, and TREZOR’s role in safeguarding your assets.
Key Scenarios During a Chain-Split
1. BIP91 Activation
- Outcome: SegWit activates smoothly without a network split.
- Window: July 21–29 historically.
- User Action: None required.
2. BIP148 UASF Activation (Partial Network Support)
- Outcome: Bitcoin splits into two parallel chains—BIP148 Bitcoin and Legacy Bitcoin.
- Cause: BIP148 nodes reject non-SegWit blocks.
- User Impact: Balances may appear differently depending on the node you connect to.
3. BIP148 UASF Activation (Full Network Support)
- Outcome: BIP148 becomes the longest chain; Legacy chain discards.
- Result: No split—all nodes update to SegWit.
4. SegWit2x Activation Without BIP148
- Outcome: Network fractures into two incompatible chains (SegWit2x and Legacy Bitcoin).
- Risk: Prolonged uncertainty and potential loss of transaction reversibility.
TREZOR Users: Why You’re Protected
- Coin-Agnostic Design: TREZOR interacts with any blockchain node (Legacy, BIP148, SegWit2x).
Precautions:
- Avoid sending/receiving bitcoins during network instability.
- Ignore "coin-splitting" services—private keys automatically cover forked coins.
- Flexibility: Switch between node types in TREZOR Beta Wallet.
FAQs
Q1: Will my bitcoins disappear if the chain splits?
A: No. You’ll own balances on both chains if the split is permanent.
Q2: Should I move my bitcoins before August 1st?
A: No. Transactions during instability risk being invalidated.
Q3: How does TREZOR handle multiple chains?
A: It signs transactions for whichever blockchain your connected node supports.
