Curious about what’s the optimal restaking period for you to maximise your returns on staked $ZIL?

Check out this article by our community member Kamran on our LearnBlockchain.org educational portal!

Here are some key takeaways from the article
- If you stake less than 3,662 $ZIL claiming more than once a year results in a loss (due to fees)

- Claiming in random intervals (i.e. 7 or 30days) vs optimised periods (i.e. daily) results in a huge difference w large amounts(16mil in the example)

- For around 1M $ZIL the optimum claim and restake cycle is at 7 days giving you the max returns

- Optimise your claiming schedules if your goal is to accumulate more $gZIL
This is just the condensed version of what the article states, to get a better understanding of how these calculations come about and the assumptions made, we suggest you read the article. The article is definitely insightful and will help you in deciding on when to compound for you to optimise your $ZIL and $gZIL gains!

Dear Community,

The network is currently down. Our team is quickly working to resolve the issue.

We will update you once the issue is solved. We apologise for any inconvenience caused!

As always, your funds remain SAFU.

The Zilliqa Team

Dear community,

We have noticed that several nodes in the network have gone out of memory after we introduced a new memory limit management in the network recovery that occurred an hour ago. We are 1) conducting a re-recovery of the network 2) removing the management limit and 3) increasing the node memory to mitigate this issue.

We sincerely apologize for the inconvenience caused.

Dear community members,

We have noticed memory management with regards to processing very large smart contracts. We are temporarily disabling transaction processing within the mainnet. Blocks will be produced with 0 transaction.

We will implement the fix and upgrade the mainnet in the next 24 hours to resolve the issue.

For the more technical folks, this issue is a result of memory fragmentation, which in turn unable to return memory to the kernel. If you are interested, here is a good blog article we found to explain the issue.
https://www.algolia.com/blog/engineering/when-allocators-are-hoarding-your-precious-memory/

Dear everyone,

Thank you for your patience while transactions processing is disabled on Zilliqa mainnet.

As part of the fix to resolve the large memory consumption on the mining nodes for DS Committee, we will be conducting a network upgrade to version tag v8.0.5 at block number 1283088. This upgrade is likely to take place around 14 July 6.45 AM UTC. For more information on this urgent upgrade, please refer to the release note at Zilliqa v8.0.5 release notes (https://github.com/Zilliqa/Zilliqa/releases/tag/v8.0.5)

Do note that during the upgrade period no transactions will be processed by the network and blockchain API may not be accessible.

Thank you for your continued support!

Dear community members,

The mainnet urgent upgrade of v8.0.6 has been completed (14 July 2021 11:20 UTC). As part of this urgent upgrade, we fixed an issue that can cause mining node to go out of memory. Release note is at https://github.com/Zilliqa/Zilliqa/releases/tag/v8.0.6

We apologize for the inconvenience caused.

4 YEARS. 5 THEMES. INFINITE POSSIBILITIES: DISCOVER MORE ON 30 JULY! 4️⃣🥳🎉🎉

The countdown for our 4th B'day celebrations begins! Join us live on Youtube, 30 July, 10PM SGT to learn how the Zilliqa ecosystem is BUIDLing and thriving.

We'll talk about our milestones and vision across 5 core segments, all of which come under the #ZIL4ALL umbrella theme.

Can't wait to celebrate with you all!

Dear all,


The last major upgrade v8.0 (https://github.com/Zilliqa/Zilliqa/releases/tag/v8.0.0) was feature packed. It reduced the block time, revised the consensus protocol, introduced remote state reads for Scilla, adjusted priorities for new miners, and included several other core optimizations and bug fixes. However, since that upgrade, the network has at times become unstable. This has required the core team to intervene on several occasions to introduce patches, resulting in unwanted network downtime.

We understand the frustration and inconvenience that the upgrade has caused to token holders, exchanges, wallet providers, miners and other relevant parties. The intention of this post is to share details around this topic, our general development and testing process to bring transparency to you all and steps we plan to take to reduce the chances of such events as we move forward.

As you already know, the underlying tech at Zilliqa is cutting-edge and we are constantly innovating and adding new features to the protocol. Our approach to introducing these new features follows established industry-standards of writing unit tests and running correctness and stress tests. Once the changes and unit tests are fully ready, we run these new changes on a private small-scale network for a period of time, followed by a large-scale integration at the mainnet-scale and then deploy the changes on a public testnet open for all to interact with. If a bug is found during testing on any of the networks, the bug is fixed and we start from the first step, by writing a unit test to capture the bug, deploying the fixes on a private network and so on.

Many of these cutting-edge innovations in engineering and development however present a key challenge. Until these changes go live on a production mainnet system, it is impossible to be certain that the introduced changes are free of bugs. While we discourage testing anything in production, sometimes it is clear that the real test is always in production.

We would also like to highlight that some issues are beyond our codebase and control as there could be dependencies on external systems, libraries and infrastructures. The most recent memory issue is a good example of this (https://www.algolia.com/blog/engineering/when-allocators-are-hoarding-your-precious-memory/). In many cases, we are forced to push a fix upstream to well known open source packages or have a workaround if there is no viable solution.

Guaranteeing that a given piece of software is free of bugs is close to impossible but we certainly try to ensure that. Despite these challenges, we are committed to constantly innovate and add new features to the chain with minimal disruption and bugs.

To this end and given the recent downtime, we are also taking our testing process a step further, by using formal verification tools to model the system and formally verify the generated model and whenever possible the implementation. Even though formal verification tools require extensive man hours, they are extremely helpful in verifying correctness, reliability and dependability of mission critical software systems. The goal is to combine unit testing and formal verification which complement each other in detecting any design or implementation issues with critical parts of the codebase. In order to mitigate the issues further, we are planning to reduce the frequency of the network upgrade that contains new features which will give more time for the network to test features in the wild. We will also reduce the number of features that will go in a given release to minimize the size of the new code that gets exposed.

Part 2)

On a separate but somewhat (un)related note, while troubleshooting the latest bug, we happened to notice a couple of smart contracts deployed on the mainnet where the implemented logic makes the contract state grow with new transactions. As a fix, we are going to fine tune some of the parameters which are currently set that allows the underlying design patterns to go unnoticed during development and testing. Better static and dynamic analysis tools will also help warn developers in this regard.

Do note that such contracts may work fine for now but may sooner or later hit the block gas limit, rendering these contracts uncallable. We encourage developers to be mindful of this and other similar design patterns. For example, if a contract is using a list and if that list grows with every single transaction, this may create issues in the future for the contract. Also, contracts should avoid loops whenever possible as loops on a very large list or map will hit the block gas limit at some point. Similarly, it’s advised to adopt a pull model instead of a push model, i.e., instead of a contract computing and distributing rewards to several users (push model), the contract should be designed in a way that each user could claim his own reward himself (pull model). Some relevant and useful tips on this and other design patterns around smart contract development can be found here: https://scilla.readthedocs.io/en/latest/scilla-tips-and-tricks.html# and https://docs.soliditylang.org/en/v0.4.24/common-patterns.html

Thank you for your understanding and your support. We will keep pushing ourselves to make Zilliqa a better and robust platform for all to use.

Sincerely,

The Zilliqa Team
