Vanar implements a First-In, First-Out (FIFO) transaction ordering model to deliver fairness, clarity, and operational efficiency at the protocol level. Every transaction enters the mempool and is queued strictly by arrival time. When a block is produced, transactions are included sequentially from the front of the queue until the block’s fixed gas limit is reached. Any transactions that do not fit are preserved in order and carried forward to the next blocks, rather than being dropped or reshuffled. This disciplined approach mirrors real-world queue systems and makes network behavior transparent and easy to reason about.
FIFO ordering fundamentally improves fairness. On many blockchains, transaction priority is determined by fees, leading to bidding wars that favor large players and expose users to front-running and manipulation. Vanar removes this dynamic by treating all transactions equally, regardless of fee size. If a transaction is submitted earlier, it is processed earlier. This clear rule reduces MEV-style exploits and creates a more level playing field for DeFi, NFTs, gaming, and consumer applications.
From a user experience standpoint, FIFO is critical for adoption. Mainstream users and brands expect predictable outcomes, not execution that feels arbitrary or pay-to-win. Strict ordering allows applications on Vanar to provide reliable confirmation timelines and consistent behavior, making blockchain interactions feel closer to familiar digital systems where queues are respected.
FIFO also supports scalability without instability. During periods of heavy activity, excess transactions are smoothly deferred to future blocks instead of triggering reordering, fee spikes, or chaotic execution. This preserves network stability under load and gives developers confidence that transaction flow will remain consistent as usage grows.
By combining FIFO transaction ordering with low fees, optimized block parameters, and a secure architecture, Vanar delivers a blockchain designed for real-world use. Transactions are not auctions—they are entries in a well-managed queue. This simplicity and predictability make Vanar more transparent, trustworthy, and well-suited to onboarding the next wave of Web3 users.
