Today we're tackling an issue that every blockchain developer has faced at least once: the dreaded mempool congestion. Imagine it's rush hour, and every transaction is a car trying to get to its destination. But, there's a twist – some cars have a VIP pass, while others seem to be invisible to the traffic lights. This is what happens when the mempool gets congested; some transactions get through quickly, while others are left hanging indefinitely.

At Starton, we understand the importance of every transaction reaching its destination efficiently. That's why we've developed a robust Relayer that acts like the ultimate traffic controller, ensuring a smooth flow in the busiest of times. Here's how we solve the mempool conundrum.

The Mempool Dilemma

A blockchain mempool is like a waiting room for transactions before they're added to the block. It's essential, yet it can get so crowded that some transactions are forgotten – like paperwork on a busy desk.

When the mempool gets congested, nonces (those unique identifiers for transactions) can be overlooked, leading to unprocessed transactions.

Starton's relayer consistently monitors the mempool, ensuring that no transaction is neglected, effectively managing the queue, and addressing the risk of forgotten transactions.

Each Network, Its Own Mempool

Decentralization isn't just a buzzword; it's the backbone of blockchain technology. Each network node has its mempool, each as unique as a fingerprint.

Why focus on the first 64 transactions? Well, for many wallets across different networks, this is a boundary that signifies the mempool limit.

If a network only looks at the first 64 transactions, any beyond that could be in limbo.

Our goal is to ensure no transaction, regardless of its number, gets left behind.

Transaction Presence Issues

In blockchain ecosystems, transactions can occasionally become "invisible" if the network prematurely considers them known.

Invisible transactions can mean lost opportunities and time. In blockchain terms, this leads to transactions being neither processed nor acknowledged, causing potential disruptions in the sequence and overall network performance.

To tackle this, Starton's relayer is designed to detect these phantom transactions. It cross-references the mempool against its internal log, flagging and re-submitting any transaction that has not been confirmed. This ensures that every transaction is accounted for and given the attention it requires to be validated and executed.

The Art of Rebroadcasting

When transactions are broadcast again, it's not always smooth sailing. There are various errors that could pop up, complicating the process.

Common errors such as "not enough funds" or "replacement transaction underpriced" are not just simple roadblocks; they indicate deeper issues within transaction queuing or fee estimation processes that could hinder the flow of operations within the network.

Starton's relayer is equipped to navigate these complexities. It performs an in-depth analysis of each error message, tweaking transaction parameters such as gas fees or nonce values, and ensures that each transaction is successfully re-submitted. This meticulous approach ensures a higher success rate for transaction completions, maintaining the network's reliability and efficiency.

The Nonce Challenge

Managing nonces is crucial but tricky. There's no easy way to get all transactions sorted by nonce from the network. Without an easy way to order transactions by nonce, the blockchain can get confused. That’s why, we’ve built a system that keeps track of nonces in a dedicated database, ensuring each transaction is processed in the correct order.

Forgotten transactions can lead to nonce nightmares, but not on our watch. A lost transaction could mean a nonce mismatch, leading to further issues down the line. We've engineered our system to anticipate and resolve these issues, keeping our users' experiences error-free.

Nonces are a critical aspect of maintaining the integrity of blockchain transactions. Efficient nonce management preserves the sequence and order of operations. In this article, we want to share what we’ve discovered on the complexities of nonces and explain how Starton Relayer solves nonce-related issues.

Understanding Nonces

A nonce is a unique number assigned sequentially to each transaction to ensure it is processed once and in the correct order. It is fundamental in preventing double-spending and discrepancies in the transaction sequence.

Poor nonce management can lead to lost or duplicate transactions, thereby increasing network fees and execution delays.

Is it really that complex?

Each blockchain wallet has a nonce count that must remain unique and accurate. This presents a significant technical challenge, especially when multiple transactions are sent in rapid succession or simultaneously.

When blockchain applications scale up, managing the sequence of transaction nonces becomes increasingly complex because each user's transaction requires a sequentially ordered nonce. As more transactions occur simultaneously and across different servers, there's a risk that two machines might assign the same nonce to different transactions, causing a conflict known as nonce duplication.

Scaling challenges include ensuring concurrent transactions receive unique nonces, maintaining consistent nonce information across all network nodes, managing the queue of pending transactions, handling errors and conflicts efficiently, and optimizing resources to cope with the increased demand without compromising performance. Overcoming these hurdles typically involves the use of synchronized databases, queuing systems, and robust algorithms capable of managing a distributed network's complexities.

When can the nonce go wrong?

Improperly managed nonces can block the transaction queue, waiting for the correct nonce to be processed. This is particularly problematic for sequential transactions where each depends on the previous one's success.

A server crash can lose track of nonces, leading to sequencing errors once back online. Recovery from a crash, therefore, demands special attention to nonce management.

The role of Starton Nonce Manager

The relayer is a key component in the blockchain infrastructure, tasked with the critical role of managing nonces:

Pending Transactions: The relayer stays vigilant, monitoring the transaction pool for pending transactions. It manages nonce assignment for subsequent transactions to prevent any clogging in the transaction pipeline.

Duplicate Transactions: To avoid the repercussions of nonce repetition, the relayer scrutinizes each transaction for nonce uniqueness. This step is essential in preventing the extra costs and network congestion that come with duplicate transactions.

Blocked Transactions: When transactions get stuck due to nonce mismanagement, the Relayer has a strategy in place. It deploys a dummy transaction with a proper nonce to free up the transaction queue, ensuring a smooth flow for subsequent transactions.

Server Crashes: In the event of a server crash, the relayer's use of persistent storage like Redis becomes invaluable. It allows for a swift recovery of nonce states, guaranteeing a seamless continuation of transaction processing with no data loss.

Nonce Synchronization: The Relayer also plays a critical role in environments with distributed transaction origins. It harmonizes nonce distribution across different nodes, maintaining a consistent transaction order and preventing nonce conflicts.

Through these mechanisms, the relayer effectively addresses the complexities of nonce management, promoting an efficient and orderly processing of blockchain transactions.

Using Redis for Nonce Management

Redis is pivotal for Starton's relayer in managing nonces, offering a reliable database that tracks and updates nonce states persistently. This ensures transaction order is unaffected by server crashes, as Redis can quickly restore the last known state, allowing transactions to resume without disruption. Its ability to handle high transaction throughputs with low latency, coupled with real-time synchronization across systems, helps the relayer maintain transaction continuity across different nodes. Moreover, Redis's redundancy and failover mechanisms provide an additional layer of reliability, ensuring that nonce management remains robust against system failures.

Strategies for Managing a Stuck Nonce

To manage a stuck nonce, Starton's relayer adopts several tactics. It can passively wait for an outside transaction to naturally clear the blockage, effectively unjamming the nonce sequence without intervention. Alternatively, for a more proactive approach, the relayer can inject a dummy transaction specifically crafted to unstick the nonce. This dummy transaction acts as a catalyst, restoring the smooth flow of subsequent transactions and ensuring the integrity of the transaction queue.

Effective nonce management is vital for the smooth operation of the blockchain. Starton's relayer plays a key role by ensuring each nonce is allocated and utilized properly, thus avoiding additional costs and delays. With Starton, users can focus on their core business while leaving the complexity of nonce management in the hands of experts.

In the dynamic world of blockchain, managing transactions efficiently is crucial. A key aspect of this is dealing with the volatile nature of gas prices, which can significantly impact the success and cost of transactions on the blockchain network.

What’s the deal with gas price ?

In blockchain transactions, gas refers to the computational effort required to execute operations. This cost, paid in the network's native currency, is akin to fuel for a vehicle – necessary for the transaction's journey through the blockchain.

The total cost of a blockchain transaction is analogous to a car trip, where the total expenditure is the product of the amount of gas (gas limit) and the price per unit of gas (gas price).

Gas prices are notoriously unstable, changing rapidly based on network demand and activity. This volatility can leave transactions pending for extended periods, especially if the gas price set by the user is too low during times of high demand.

The fluctuating gas prices lead to user frustration due to unexpected delays or increased transaction costs, impacting the overall user experience.

Challenges Associated with Gas Prices

Risks of Low Gas Price:

Transactions with insufficient gas prices face longer processing times or maybe outright rejected during periods of high network congestion. This can be particularly problematic during unexpected spikes in network activity. Transactions risk being stranded if the gas price offered is significantly lower than the prevailing market rate, leading to inefficiencies and possible transaction failures.

Complexity in Adjusting Gas Prices:

Blockchain networks typically require a minimum increase (often 10%) for transaction replacement. This rule poses a challenge in quickly adapting to rapidly changing network conditions. Users frequently encounter errors like "replacement underpriced," which occur when attempting to accelerate a pending transaction by replacing it with one that offers a higher gas price but fails to meet the network's minimum increment threshold.

Starton’s Intelligent Gas Estimation

Starton’s Relayer utilizes advanced algorithms to offer an accurate gas price estimation, thereby ensuring that transactions are neither delayed due to low gas prices nor become exorbitantly costly. This approach, akin to planning a car trip with optimal fuel efficiency and cost-effectiveness in mind, ensures that transactions are processed in a timely and cost-effective manner. The Relayer strategically increases the gas price by 15% at regular intervals until a fixed limit is reached to ensure transactions are processed efficiently, especially during times of network congestion, without breaking the bank. This proactive measure, slightly exceeding the typical minimum increment required by blockchains, is designed to avoid transaction delays and ensure a smoother transaction experience.

Smart error management

The Relayer adeptly manages transaction errors, such as "replacement underpriced," by dynamically adjusting gas prices and other transaction parameters. This ensures transactions are less likely to be stuck or failed. This responsive approach to error management significantly enhances the reliability and efficiency of blockchain transactions for Starton users.

Flexible Transaction Parameters:

Starton's Relayer provides users with the flexibility to customize transaction parameters, catering to both novice users seeking simplicity and expert users requiring detailed control over their transactions.The potential for future enhancements, including customizable gas price increments, reflects Starton's commitment to evolving with user needs and blockchain technology advancements.

In the fluctuating realm of blockchain, managing gas prices effectively is vital for seamless transaction processing. Starton’s Relayer addresses this challenge head-on, providing a robust and user-friendly solution.
