2ACoin Core v1.1.8 SoftFork Success
The two soft forks scheduled to go into effect at block 390,000 & block 391,000 were implemented without any issues!
As per the GitHub Release notes for 2ACoin Core v1.18 release there were 2 soft fork implementations scheduled @ block 390,000 and block 391,000. We are happy to announce that both soft forks were implemented successfully!
Both of these soft forks were implemented in the 2ACoinD daemon software. A quick summary of the soft forks follows.
2ACoind Updates – Soft Fork Summary
- BugFix: Block Transactions Blob Shuffle
- Implemented in scheduled network upgrade at block 390,000
Fixed the order that cached transactions are extracted from the transaction blob by the daemon. As different daemons can have different orders, the cache gets a slightly different state. This is then abused to create transactions that are only compatible on chains with a given state by an attacker. This step can then be repeated until most daemons get out of sync with different local information about transactions, mining blocks that are not valid for the others.
- BugFix: Timestamp Locked Input Transactions
- Implemented in scheduled network upgrade at block 391,000
Fixed transactions with timestamp encoded unlock can be abused to force block creation that is only valid for a partial group of the chain based on their local timestamp. If a block contains transactions with inputs locked on timestamp base the unlock is validated against the local timestamp. But this timestamp is not necessarily the same on all daemons, thus if chosen toxic you can let people mine blocks that are only partially valid in the blockchain.
We want to Thank the entire 2ACoin Community for upgrading their 2ACoin Core software to v1.1.8 thus ensuring the success of these soft forks.
2ACoin is designed and developed to support the American Right to “Keep and Bear Arms” as set forth in the 2nd Amendment to the Bill of Rights established on December 15, 1791. To meet this goal, 2ACoin includes a pre-mine of 10% of the total available coins (1.791 million ARMS) that will be donated to the Firearm Community over the next 10 years.
The 2ACoin team is constantly working to provide commitment and value to the 2ACoin community. We want to Thank the 2ACoin Team for implementation of these 2 soft forks to ensure the security of the 2ACoin Network.
