Aptos’ Latest Breakthrough: Faster Than Ever at Scale

Most chains get slower as they scale. Aptos keeps getting faster. Introducing Consensus Observer: Cutting End-to-End Latency by Half at 10k+ TPS. What you need to know about the latest latency breakthrough to arrive on Mainnet.

TLDR; Sub-second isn’t a claim — it’s a commitment.

Traditionally, fullnodes wait until validators execute and commit a block before syncing it. That delay can add hundreds of milliseconds — or more at high TPS.

Consensus Observer (CO) changes that by allowing blocks to be shared immediately after ordering, before execution or commitment. CO is the answer to a key question: What’s the fastest way to get fullnodes access to block data—so they can process in parallel with validators?

With CO, fullnodes now:
• Receive blocks in real-time
• Execute alongside validators
• Commit once consensus finalizes

The result? Massive latency gains.

Since its deployment, CO has cut end-to-end latency by ~50% at higher loads (8.5k+ TPS). And unlike most systems, CO improves both average (P50) and tail (P90) latencies — making performance more predictable, too.

Why it matters: Consensus Observer is live on Mainnet, unlocking use cases that require ultra-low latency and low-cost transactions: • Micropayments (e.g., per-second content billing) • Streaming payments • Autonomous payments triggered by real-world events These demand speed, predictability, and scale. Aptos delivers all three.

absolutely the best blockchain, but there is nothing interesting in ecosystem projects (emoji only) Сan this be fixed somehow? As for me, it is much easier to pump an ecosystem than to achieve current values ​​in Aptos chain
