Dear mining and seed node operators,

We have released a new optional fix version v8.0.7. This version addresses an issue where node processing large contract states during syncing may run out of memory. This usually happens to nodes running with 4 GB of memory or less. If you encounter this issue, you are advised to use the new version. For nodes who are not experiencing this, you may still continue to use v8.0.6.

:exclamation:️ Please remember to save your mykey.txt as usual before carrying out any upgrade. :exclamation:️

Please make sure to use the v8.0.7 docker image or native build, and use the new v8.0.7 configuration files to join the Zilliqa mainnet.

Dear Zilliqa ecosystem,

We have noticed shard nodes have failed to join the network in epoch 1315200. We received about 426 PoW solutions instead of the expected > 1800 PoW solutions (shard level). As a safety precaution, transaction processing was temporarily disabled between blocks 1315219 and 1315326.

The shards node has since rejoined successfully on block 1315300 with > 1800 PoW solutions (shard level) received this round.

All transaction processing has resumed starting block 1315326 and the network is progressing well.

Regards,
Zilliqa team

Dear Zilliqa ecosystem,

We are observing an issue with the network where several nodes are currently out of sync and the network is currently unable to process any transactions. The likely cause of the issue is likely to be due to node memory issues.

We will be performing a network recovery and will keep you posted.

For exchanges, we will recommend closing deposit and withdrawal till the network is recovered and transaction processing is resumed.

Regards,
Zilliqa team

Dear All,

We will be conducting a network upgrade to version v8.1.0 on Monday 30th August 2021 from UTC 03:30 to 10:00 hrs.

This release will introduce important new features to enable ZilBridge such as:
- Merkle Patricia tree data structure for contract storage
- Contract proof API

It will include several stability, maintenance and bug fixes such as:
- Several memory clean up improvements
- Improve network stability for JSONRPC API service
- Improve PoW submission handling
- Node syncing improvement

The recommended hardware specifications for our mining nodes have not changed since the launch of the Zilliqa mainnet. However, with the network processing more and more contracts, we will be updating the mining node’s minimal recommended specifications to the following:
- 4 GB memory --> 8 GB memory
- At least 50 GB SSD disk storage

For more information on this upgrade, please refer to
1. Zilliqa v8.1.0 release notes: https://github.com/Zilliqa/Zilliqa/releases/tag/v8.1.0
2. Scilla v0.11.0 release notes: https://github.com/Zilliqa/scilla/releases/tag/v0.11.0

❗️Attention: miners on the Zilliqa Mainnet❗️
Please note that all nodes will have to rejoin the network to perform this upgrade. The new configuration files for v8.1.0 are expected to be ready for download by Monday 30th August 2021 10:00 hrs.

Please remember to save your mykey.txt as usual before carrying out any upgrade. When you have successfully upgraded your node, you will be welcomed with the message:
"Copyright (C) Zilliqa. Version v8.1.0." in the zilliqa-log text file.

❗️Attention: exchanges hosting seed nodes❗️
The new seed node configuration files for v8.1.0 are expected to be ready for download by Monday 30th August 2021 10:00 hrs.

❗️Attention: Staked seed node operators participating in staking❗️
Please ensure that you upgrade your node within 48 hours after the completion of the mainnet upgrade to`v8.1.0`. The staking verifier will resume checks after 48 hours, and if your node is not upgraded by then, your delegators may lose stake rewards.

Do note that during the upgrade period no transactions will be processed by the network.
As such, we recommend that mainnet deposit and withdrawal services be temporarily suspended during the network upgrade.

We will notify you once the network upgrade is completed. Thank you for your continued support!

Dear exchanges and ecosystem,

We noticed an issue with the recent upgrade. We are pausing the processing of the transactions while we investigate the issue.

We will keep you posted

Regards,
Zilliqa team

Dear everyone,

The mainnet recovery of v8.1.0 has been completed (31 Aug 2021, 11:30 UTC). Please download and use the new configuration for v8.1.0.

This recovery addresses an issue observed with the most recent network upgrade. For more information, please refer to the following blog post: https://blog.zilliqa.com/post-mortem-report-for-mainnet-upgrade-v8-1-0-94d00ce23ff2

If you are an exchange provider, then do note that the network was rolled back to block number 1,394,088. This was the block number when the last network upgrade happened (on Aug 30, 2021). If you had not opened the ZIL deposit/withdrawal after the last upgrade, then you do not need to take any action. However, if you had opened the ZIL deposit/withdrawal, do note that all the transactions were replayed back to counter the effect of the network rollback.

:exclamation:️ Please remember to save your mykey.txt as usual before carrying out any upgrade. :exclamation:️

Please make sure to use the v8.1.0 docker image or native build, and use the new v8.1.0 configuration files to join the recovered Zilliqa mainnet.

Dear Zilliqa community,

We are making a small update to the Zilliqa ZRC-6 NFT standard. We will be adding “token_owner” to the events emitted in the following transitions
- SetSpender
- AddOperator
- RemoveOperator

https://github.com/Zilliqa/ZRC/blob/master/zrcs/zrc-6.md

This update will provide more verbose information for events emitted. It will useful for use cases like NFT indexer and frontend interacting with ZRC-6 contracts. We have also updated the ZRC-6 reference contract on Neo-savant IDE.

Thanks SpardaWallet for the suggestion.
