2ACoin - Production Release.

v2.1.5

Special Notes

End of Life (EOL) Notice
Please note that v2.1.x are the last releases to contain 2acoin-service. Releases after v2.1.x will no longer contain the 2acoin-service binaries and the code will be removed. The next release will not contain 2acoin-service or any legacy WalletGreen dependencies. If you have not converted your wallet(s) and or services over to Proton, zedwallet, or wallet-api you are encouraged to do so soon. The next release will remove all legacy support for older wallets and the daemon API will be changed thus rendering 2acoin-service inoperable. Should you experience any issues working with wallet-api, please make sure that you open an issue so that the issue may be resolved as quickly as possible.

This also establishes the timeline for the End of Support (EOS) of 2acoin-service being the next release (v3.0.0). With the release of v3.0.0, 2acoin-service will no longer be supported or work with the core software.This release includes the replacement for legacy zedwallet. Legacy zedwallet has been replaced with zedwallet++ and all legacy zedwallet code has been removed. Please make sure that you have backed up your keys from legacy wallets, then upgrade them to the new format by using zedwallet, wallet-api, or wallet-upgrader in this release and ensure 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.

Full Node Resync May Be Required
The new version of 2acoin-service will require a full re-sync. If you are using 2acoin-service you will be required to re-sync your node or create a new wallet for v2.1.5.

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.

Checkpoints
To help speed up your sync, you may use checkpoints to help speed things up. (Review the steps on how to sync quickly below)

v2.0.1

Special Notes

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 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.

Checkpoints
To help speed up your sync, you may use checkpoints to help speed things up. (Review the steps on how to sync quickly below)

SoftFork
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.

Release Notes

General Updates

Added an additional EU (Amsterdam) seed nodes
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

2ACoin - Production Release.

v2.0.0

Special Notes

Network Soft Fork
Upgrade to this release is Mandatory by block 455,000!
Please update your software before block 455,000 to ensure you remain synced with the network (see details below).

Features/Enhancements
2ACoin v2.0.0 release of the core 2ACoin software suite activates a network upgrade at block 455,000 that implements block major version 6. Block Major Version 6 changes the Proof-of-Work (PoW) algorithm to Argon2/Chukwa for 2ACoin.

Miners currently mining 2ACoin/ARMS will be required to switch their miners from Cryptonight-Litev7 to Argon2/Chukwa upon upgrade of the network at Block 455,000. Please refer to our block for additional information as it is released.

In addition to our blog, we urge users to join the 2ACoin Discord and follow the #announcements channel to be notififed of the latest 2ACoin updates.

2ACoin pools, miners, and services can do their part by upgrading their daemons as soon as possible.

Known Mining Software With Argon2/Chukwa Support

xmrigCC (xmrig fork)
- xmrigcc-donation-proxy (xmrig-proxy fork)
xmrig
- xmrig-proxymore
Team Red Miner (closed source)
CryptoDredge (closed source)
Crypto Webminer source code behind 2ACoin WebMiner https://miner.2acoin.org)
more coming soon...

Please review your selected mining software's documentation for how to activate the proper algorithm for mining Argon2/Chukwa after the network ugprade.

If your preferred mining software is not listed above, please contact the developer/maintainer of the package and let them know you want Argon2/Chukwa support!

Known Mining Pool Software With Argon2/Chukwa Support (For Pool Operators)

2ACoin-Nodejs-Pool
more coming soon...

The changes for supporting Argon2/Chukwa in most pool software packages is minimal. If your pool software uses the Node8-Multi-Hashing Node.js module then we have a modified version (node8-multi-hashing) for you to use. However, if you need assistance adding support to your pool, please feel free to ask for assistance in the 2ACoin Discord in the #dev_pool channel.

2ACoind Default Settings Change
The default database write buffer size, read buffer size, maximum open files, and background threads have increased to help with daemon stability. The increases are as follows:

Write Buffer Size: 256MB -> 256MB
Read Buffer Size: 10MB -> 256MB
Maximum Open Files: 100 -> 125
Background Threads: 2 -> 4

These values may need adjusted based on your system resources, configured limits, etc. Please review the 2ACoind --help for changing these values at runtime.

Release Notes

General Updates

Removed unused code from the project.

2ACoind Updates

Bugfix: QueryBlocksDetailed does not populate transaction extra "raw" property in response
Bugfix: Return better error messages via the node /sendrawtransaction method
- This now returns an informative error message in the error property of the response on why a submitted transaction failed to be broadcast to the network
P2P version increased to version 6 to assist with the upcoming network upgrade
- Minimum version now set to 5
Increased the default DB write buffer size, read buffer size, max open files, and number of background threads to improve daemon performance.
Clarified the error message generated when a submitted transaction contains already spent input key images
Removed all references to testnet as that has not been supported in production code for quite some time.

zedwallet Updates

Bugfix: Zedwallet crashing when parsing extra)
Bugfix: Resolved issue in edge cases where parsing of the public key from tx_extra would fail.

zedwallet-beta Updates

Bugfix: Resolved an issue in handling inputs during chain reorganization events
Bugfix: Resolved issue in edge cases where parsing of the public key from tx_extra would fail.
Added support for skipCoinbaseTransactions that is enabled by default that skips scanning coinbase transactions as the large majority of users do not directly receive block rewards.

2ACoin - Production Release.

v1.1.7

Special Notes

Network Soft Fork
Upgrade to this release is Mandatory by block 365,000!
Please update your software before block 365,000 to ensure you remain synced with the network (see details below).

Features/Enhancements
2ACoin v1.1.7 release of the core 2ACoin software suite activates a network upgrade at block 365,000 that restricts transaction extra to a maximum of 5,120 bytes to prevent chain storage bloat. This release also activates logic immediately that stops transactions exceeding this size limit from entering the transaction pool or being selected during the getblocktemplate calls; however, until block 365,000 transactions included in a block may still have transaction extra data exceeding the 5,120 byte limit.

This release also includes a network upgrade at block 365,500 that forces the verification of the signature counts on transactions sent throughout the network. This upgrade helps reduce the risk of blockchain bloat from malformed transactions.

Pools, miners, and services can do their part by upgrading their daemons as soon as possible.

Release Notes

General Updates

Resolved a few edge case bugs whereby block synchronization may fall-through to different code paths.

How To Sync Quickly

In 2ACoin v1.1.0 we introduced the ability to sync a fresh chain from block 0 much quicker by loading "checkpoints" with your 2ACoind daemon.

Here are the steps to sync via checkpoints;

download the latest checkpoints.csv (https://github.com/2acoin/2acoin-checkpoints)
place checkpoints.csv in the same folder as your 2ACoind daemon
run 2ACoind with checkpoints added like this:
Linux, Apple ./2ACoind --load-checkpoints checkpoints.csv
Windows 2ACoind.exe --load-checkpoints checkpoints.csv

How To Upgrade from an Older Version

(windows, mac, linux)

Run the old 2ACoind to fully sync your chain
with the old 2ACoind fully synced, open zedwallet
With zedwallet open, export_keys your SPEND and VIEW keys, this is important.
- If you are in windows, right click the titlebar of the CMD window and select EDIT then MARK so be able to copy and paste your keys.
Unzip the new 2acoin files into a NEW FOLDER outside of the old version folder
Close the old version folder 2ACoind and zedwallet by typing exit into each window
Run the new 2ACoind
Run the new zedwallet
Press I for IMPORT in zedwallet
Enter your spend_key and your view_key from step 3
Use any filename for the wallet name, it does not have to be the same
Use any password for wallet password, it does not have to be the same as the last
Your wallet is now updated

RPC API Changes

Developers seeking to integrate the 2acoin-service daemon into their applications should note this crucial change.

Mandatory authentication has been added to the JSON RPC API interface for 2acoin-service. To maintain backwards compatibility with old services, the --rpc-legacy-security flag has been introduced to allow password-less access to the RPC.

However, all new applications going forward should make use of the --rpc-password flag to enable authentication of JSON RPC queries.

To pass the password to the RPC interface, add an additional field password to the JSON object:

{
	"jsonrpc": "2.0",
	"method": "transfer",
	"params": {},
	"password": "<the password>"
}
