Bitcoin Cash will undergo a scheduled protocol upgrade on 15 November 2018.
However, since this upgrade is expected to be contentious, please take careful note of our recommendations below.
Prior to 15 November:
- Ensure you have the latest Bitcoin Cash wallet software on your server.
- On or before 14 November, remove BCH from your admin's 'Machine Settings > Setup' panel, thereby ceasing Bitcoin Cash transactions.
- Make a backup of your BCH wallet.
Following 15 November:
- Watch relevant cryptocurrency outlets for news relating to the hard fork.
- If there is not a fork resulting in two coins, and the BCH network is stable, you may safely re-enable BCH in your admin.
- If there is a persistent fork which results in a second coin which you also wish to preserve, do not yet re-enable BCH. (Please read the rest of this article.)
- Watch @LamassuSupport on Twitter for any further recommendations.
Since the introduction of Bitcoin Cash as an option on our cryptomats, Bitcoin ABC node software has been the default installed for the BCH wallet. (As our software is open source, operators are free to run a different wallet implementation if they wish.)
However, a recent competing implementation, Bitcoin SV, is incompatible with the ruleset of Bitcoin ABC and other BCH node software. The scheduled Bitcoin ABC upgrade has been considered contentious by some, and may end in a chain split with two resulting coins.
As no replay protection would be present, cryptomats sending BCH transactions after the potential chain split would be sending both BCH-ABC and BCH-SV coins to customers (and receiving both or only one of the coins for incoming cash-out deposits).
As operators are in full control of their wallet and keys, should there be a persistent fork of the network resulting in two coins, it will be up to an operator to take necessary steps to split and claim any resulting coins, as Lamassu is not in custody of wallet funds.
As we continue to monitor the situation, we will provide updates on our @LamassuSupport feed.
