On behalf of the Shardeum engineering team, we are excited to gradually unveil a series of blog posts that reveal the behind-the-scenes efforts to build the world’s first auto-scalable smart contract platform that scales horizontally. Through these revelations, our goal is to inspire both the community and the broader Web3 ecosystem and foster future innovations. Many of the features we’re introducing with Shardeum are groundbreaking, setting new standards in blockchain technology. Achieving a feature-complete status for Shardeum isn’t just about checking off items on a list—it’s about tackling the industry’s biggest challenges, making blockchain accessible and affordable, and bringing it into the mainstream. Stay tuned—you won’t want to miss these updates!
In this blog post, we will focus on one of the latest breakthroughs on Shardeum – as we completed the implementation of network modes, notably the “Safety Mode” in late 2023. Much like a biological immune response, safety mode ensures that application transactions can be paused temporarily if suboptimal network conditions arise and that Shardeum will continue to thrive and pulse with life, processing transactions, and syncing data as long as we have active nodes. This milestone marks another significant step in our journey to bring decentralization to the masses, underscoring the advanced technology and thorough preparedness that make it possible.
We recently published an article about the network modes with a focus on "Recovery Mode" that allowed Shardeum to easily overcome a major betanet crash making it the first sharded blockchain network to self-restore all its data. Check it out now here!
With this Shardeum upgrade, network modes (of which safety mode is a key one) are now successfully integrated into the Shardus network. Network modes, in essence, are the different network states that collectively ensure that the network can manage its lifecycle effectively, from formation and operation through potential crises and even into a recovery mode, thus ensuring network stability in the case suboptimal network circumstances arise.
It is important to stress that even with the benefits that network modes bring, some of the modes such as restart or shutdown mode, may never actually arise on Shardeum. For instance, it would take all (or nearly all) validators to be lost to trigger restart mode. But Shardeum has modes like restart in order to prepare for even the most unlikely of scenarios.
Similar to traffic signals directing vehicular flow, these modes guide our network’s behavior in response to the number of active validators and other key thresholds. From a technical perspective, network modes on Shardeum are designed to respond dynamically to the needs and conditions of the network. They guide how validators interact, ensuring both performance and resilience. Let’s break down what each mode means for Shardeum:
Each mode has its time and place, even in the event of suboptimal network conditions, and the modes in their entirety ensures the network is resilient, strong and can always live on. Firstly, let’s explore the safety mode, before turning our attention to the general benefits of having this level of preparedness in the context of distributed and decentralized technology. Note, we will explore the remaining modes in detail in the upcoming posts.
Safety Mode guarantees that if there’s a significant drop in active validators, Shardeum will pivot into a protective state, prioritizing data synchronization over application transaction processing.
Safety mode is designed to maintain the network’s stability when the number of active nodes fall below a certain threshold. By limiting the network to processing only protocol transactions, it reduces the load and complexity of operations, helping to ensure that the core functions of the network remain intact and secure.
In shard-based systems, losing a significant number of nodes can risk data integrity, especially if these nodes are responsible for specific shards. By entering safety mode, the system can prevent scenarios where transactions might be incorrectly processed or where data could be lost due to insufficient node coverage.
Safety mode acts as an automatic response mechanism to sudden drops in node participation. This automated switch can be crucial in preventing cascading failures that could occur if the network continued to operate under normal conditions despite a significant reduction in active nodes.
By focusing only on protocol transactions, safety mode allows the network to operate in a reduced capacity, which is easier to maintain and manage. This simplified operation makes it easier for new or recovering nodes to sync and participate in the network, aiding in the overall recovery process.
In decentralized systems, maintaining consensus is vital. Safety mode helps preserve the integrity of the consensus process by reducing the network’s operational complexity and ensuring that remaining nodes can continue to agree on the state of the network.
In some scenarios, a sudden drop in active nodes could be due to a coordinated attack. By switching to safety mode, the network reduces its vulnerability, as only essential protocol transactions are processed, leaving less room for malicious activities to exploit a weakened network state.
Even in a reduced capacity, safety mode ensures that essential network operations continue. This means that critical updates, necessary maintenance tasks, and basic network functionalities are preserved, ensuring that the network doesn’t completely halt.
In summary, safety mode in a system like Sharduem provides a critical safety net that ensures network stability, prevents data loss, aids in recovery, and maintains the integrity of consensus mechanisms during periods of stress or reduced node activity. This mode is essential for the resilience and long-term sustainability of a decentralized, shard-based network.
So now that we have a comprehensive understanding of the benefits of safety mode, what benefits do the other major modes bring to Shardeum?
