Thanks to everyone’s dedication and quick actions, the rewind of the chain to block 694,858 has been a success! The new chain has reached the same hash rate as before, and is still increasing.

Let’s outline some of the next steps :
-All MWC network nodes (including but not limited to the Exchanges, Mining pools, etc) are expected to update their nodes to the latest 4.3.0 version, and to switch to using the new chain. Miners should not mine on the old chain (for the nodes which have a version lower than 4.3.0) any more. https://github.com/mwcproject/mwc-node/releases/tag/4.3.0. IMPORTANT for EXCHANGES: after upgrading, the old chain data will NOT be kept. To keep the old chain data for the purpose of cleaning up your transactions, you will need to backup your old chain data together with your old binary (chain_data and wallet_data respectively).

1 Before the new chain height catches up to the inflated chain height, it is strongly advised to NOT make deposit/withdraw/trading or any transactions, just continue to HODL! We will make an announcement once the new chain height passes the old (inflated) chain height.
2 If you previously received “inflated” coins they will vanish on the new chain as if they never existed. Exchanges and mining pools may have their own strategy to handle their user’s account balance.
3 AVOID making transactions with any MWC Wallet (all implementations, including but not limited to mwc-wallet, mwc-qt-wallet, mwc-713, etc.) We strongly advise that you wait until we announce that the new chain has passed the old chain height.

Current wallets will show wrong balance for next 7 days or so, avoid using them, new wallets will be released soon.

We want to thank you for your patience in advance and will continue to keep you up to date.
