The SUI blockchain has burst into the headlines with a truly impressive result. During a public stress test conducted on July 4 directly on the mainnet, the network demonstrated a peak throughput of 6,086,766 transactions per second (TPS). This figure is nearly 100 times higher than the peak performance of payment giant Visa, which stands at around 65,000 TPS. The event was open to all participants, adding to its transparency.
However, behind these astronomical numbers lies an important technological nuance. As analysts rightly note, the achieved figure is not the result of processing 6 million "native" transactions directly on the blockchain. In normal operation, the SUI mainnet functions at a level of several hundred TPS.
The secret lies in the Sui Tunnels technology — programmable state channels using zero-knowledge proofs (ZK). A user opens such a channel with a single on-chain transaction, after which millions of interactions (in the test, these were actions of AI agents, gaming processes, and micropayments) occur off-chain — instantly and without fees. The final state of the channel is then returned to the blockchain, and the ZK proof confirms its correctness.
Critics rightly point out the inaccuracy of directly comparing off-chain TPS with native TPS. But, as experts emphasize, the very idea of scaling through channels, reminiscent of the Lightning Network for Bitcoin but much more powerful and versatile, is aimed at solving real-world problems. No one needs 6 million TPS today, but users need applications that feel instantaneous: AI agent operations at machine speed, real-time gaming, and micropayments.
Technical View on SUI Price
Against the backdrop of these fundamental news, the price of the SUI token itself is testing a key descending trend resistance around $0.74. A breakout above this level could open the path to the $0.85–0.93 range. In case of a pullback, the support zone to watch is the $0.68–0.70 area.
It is important to note that SUI has already surpassed the 2.5 million TPS mark on the mainnet using these channels. The "agent race" at the speed of light has begun, and the coming days could be decisive for the asset's price.
Cryptalist Analytical Conclusion: Demonstrating 6 million TPS is a powerful foundation for the future, but for an investor, it is more important to assess how quickly the so-called "killer applications" (AI agents, complex games) that can utilize this throughput will emerge. Without them, this remains an impressive but still theoretical achievement.
