Latest Release Information
2ACoin v2.0.1 is now available for download from our GitHub Software Repository.
This release of the core 2ACoin software includes the following General Updates, please refer to the complete list of of updates on the download page.
- Added an additional EU (Amsterdam) seed node
- Scheduled network upgrade at block 585,000 that will no longer permit transaction outputs in excess of 4,477,500.00000000 ARMS to mitigate creating unmixable outputs
- 4,477,500 * 4 (current ring size) is equal to the total supply
- Wallets will refrain from creating outputs larger than 1,000,000.00000000 ARMS to mitigate the risk of creating unmixable outputs.
- This value is 1/17th of the total supply
- Limit fusion transactions in mempool to 50
- Removed unused code and other general code cleanup
- Removed some Boost dependencies throughout the code base
- Now builds consistently with boost >= 1.70
- Bugfix: OSX compilation errors in some environments
- Bugfix: resolved a bug when deserializing data in some edge cases

Special Notes About this Release
Network Soft Fork
Upgrade to this release is Mandatory by block 585,000!
Please update your software before block 585,000 to ensure you remain synced with the network (see details below).
End of Life (EOL) Notice
This release is last release to contain legacy zedwallet. Any releases of the core suite after v2.0.1 will replace the legacy zedwallet with zedwallet++ and all legacy zedwallet code will be removed. Please make sure that you have backed up your keys from legacy wallets, upgraded them to the new format by using zedwallet-beta, wallet-api, or wallet-upgrader and that you can access your wallets using the above tools.
Clarification: 2acoin-service is not being deprecated as part of this process. It will still be available until further notice specifically regarding that binary.
End of Support (EOS) Notice
Support will be provided for legacy zedwallet through August 31, 2020. After that date, legacy zedwallet will no longer be supported.
Full Node Resync May Be Required
This release contains 2 fixes to the way that data is serialized/deserialzed. The fixes are necessary for the proper operation of 2ACoind; however, the fix may reveal data corruption in your local copy of the blockchain (both the database and underlying local cache). Unfortunately, the only way to resolve the data corruption is to purge the corrupted data and resync from that point or perform a full resync.
If you encounter a message stating that your local blockchain cache is corrupted, please try the directions given (be patient, it may take a while). Or, you may resync your node from scratch.
To help speed up your sync, you may use checkpoints to help speed things up. (Review the steps on how to sync quickly from here)
This release contains a network consensus update at block 585,000 which will not permit an output of a transaction to exceed 1/4th of the total supply (4,477,500.00000000 ARMS). Due to the static mixin size requirement of 3 mixins and thus a ring size of 4, it is impossible to have enough mixins available to spend an output larger than 4.477 Million ARMS.
With 2ACoin v2.0.1 we have implemented a restriction on the number of fusion transactions allowed in the mempool. The limit is set at 50 going forward to reduce the possibility of transaction flooding of the mempool.
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.
2ACoin v2.0.1 provides new features/functionality which are designed to stabilize the ARMS network against transaction flooding. This release reflects the outstanding effort by our team whom are constantly working to ensure the stability and security of the 2ACoin network.
If you have any comments or suggestions, we would like to hear them.
