From the ground up, Vanar was built with usability, scalability, and security as core principles. One of the most common weaknesses in low-cost blockchain networks is their exposure to spam and block-filling attacks. In these scenarios, attackers flood the network with massive numbers of cheap transactions, clogging blocks and degrading performance for legitimate users. Vanar addresses this risk through a carefully engineered fixed-fee model combined with tiered pricing, refined through extensive testing.
Why Ultra-Low and Variable Fees Create Risk
On many blockchains, transaction fees fluctuate based on demand or are intentionally kept extremely low to attract users. While this may seem user-friendly, it opens the door to abuse. Malicious actors can submit thousands of low-cost, high-gas transactions to monopolize block space, delaying or preventing genuine transactions from being processed. The outcome is congestion, unreliable performance, and potential denial-of-service conditions.
Vanar’s Fixed-Fee Model
Vanar takes a different path by pricing transactions with fixed USD-denominated fees rather than relying on volatile gas-token markets or automated fee auctions. This approach gives users predictable, transparent costs while removing the uncertainty attackers often exploit. Even during sharp token price swings, transaction fees remain stable and are determined by the real computational resources required to execute each transaction.
Tiered Pricing Based on Resource Usage
Security is further reinforced through a tiered fee structure tied directly to gas consumption. Simple actions, such as standard transfers, remain inexpensive and accessible. More complex, resource-intensive transactions incur higher fees. This proportional pricing makes large-scale spam economically unviable, as the cost of consuming block space rises in line with resource usage.
Protecting Blocks from Saturation
To prevent deliberate block-filling attempts, Vanar assigns higher costs to transactions that consume excessive gas. If someone attempts to push large volumes of heavy transactions into the network, the expense escalates rapidly. This economic pressure discourages block saturation and ensures that legitimate users retain fair access to block space.
Accessibility Without Compromising Security
Vanar strikes a balance between openness and protection. Everyday users and developers can execute small to medium transactions without facing excessive costs, supporting frequent usage and real-world adoption. At the same time, the fee model aligns costs with actual network impact, safeguarding the system from abuse.
A Long-Term, Economic Defense
Instead of relying on reactive fixes, Vanar embeds security directly into its economic design. Its modular, fixed-fee framework discourages malicious behavior by making attacks financially inefficient. This results in consistent throughput, predictable performance, and long-term reliability for honest participants, even during periods of high demand.
By combining fixed transaction pricing with gas-based fee tiers, Vanar transforms transaction costs into a built-in defense against spam and block saturation—while remaining affordable, predictable, and scalable for real-world, high-volume applications.
