On August 1st, a group of users and some businesses are planning to implement a non-compatible upgrade to the network, raising the blocksize limit to 8MB and removing SegWit. As this upgrade does not have a wide backing of the network, this “hard fork” would split the Bitcoin network in two. As a result, we will be left with the Bitcoin with activated SegWit (through BIP91/BIP141) and its clone, dubbed Bitcoin Cash (Bcash/BCH).
As this is a chain-split, Bitcoin Cash (Bcash) will share its entire transaction history with Bitcoin up until the point of the split, with the history diverging after the split. This means that for whatever amount of bitcoins you had before the split, you will end up having that same amount of Bcash. Moreover, as Bitcoin and Bcash essentially become two separate currencies, they will be independent of each other. You will be able to spend your Bcash coins without spending bitcoin.This article assumes you own your private keys. With TREZOR, your private keys are in the safest place possible — in your device and nowhere else.
So what do you have to do to gain access to your Bitcoin Cash (Bcash) coins? Right now, nothing. Your action will be required after August 1st, and only if you want Bcash.What do I need to do to claim my Bitcoin Cash (Bcash)?
Bitcoin Cash (BCH) has implemented the necessary protection against replay attacks, meaning TREZOR can support the currency safely.
We will provide an interface, accessible from TREZOR Wallet, where you can access and safely claim your Bcash coins. You will be prompted by TREZOR Wallet once you select “Bitcoin Cash (BCH)” in the currency selector.
