Wallet v0.7.5 Release Notes

Since Beijing time 3.15 11AM ~ 3.16 8PM, MVS mainnet was under future blocktime attack, MVS mainnet got separated.
Attacker wrote future blocktime into each block, that caused mining difficulty drop down, then he/she controled MVS mainnet through selfish-mining.
So we decided to hard-fork at height 1030000.

MVS mainnet hard-fork already actived successfully on the safty longest chain.
explorer.mvs.org, lightwallet works well.
Please download wallet v0.7.5 to support this hard-fork to defend potential future blocktime attack.

After upgrade to v0.7.5, your wallet may be in 2 cases.

CASE 1 - current height under 1030000

open v0.7.5 wallet, check current height.
Then leave it alone, waiting for may 1 hour, see whether wallet height close to the height of https://explorer.mvs.org.

CASE 2 - current height over 1030000

That means you may in attacker’s chain. need re-sync by below tools.

  1. Stop mvsd, if running.

    $ pkill -9 mvsd
  2. Download fix-tool from here, Linux only.
