A few days ago, I attended a blockchain technology salon, and during the tea break, an old trader named Zheng complained: “Last week, I used a certain public chain for cross-chain arbitrage, and it took 17 minutes just to confirm the transaction. By the time it was my turn to execute, the arbitrage opportunity had already been eaten up, and I even had to pay a Gas fee.”
This reminded me of a set of data I came across while researching Layer 2 solutions: a certain mainstream public chain has a peak TPS of only 14. When there is market volatility, it becomes congested like a red sea, and the confirmation time for a single transaction often exceeds half an hour. The on-chain congestion fees can even surpass the amount of the transaction itself.
Later, I talked to Zheng about ERA, and with a mindset of verification, he tested a cross-chain transfer. From the Ethereum mainnet to the ERA chain, and then completing an asset exchange with another public chain, the whole process only took 1 minute and 12 seconds, with Gas fees amounting to less than $0.3. “This Optimistic Rollup mechanism is really efficient,” he said while looking at the on-chain data, “it moves a large amount of computation off-chain, only putting critical data on-chain, inheriting the security of the mainnet while increasing the throughput to over 3000 per second, and keeping the slippage within 0.1%.” #Caldera
Now, Zheng's arbitrage strategy runs entirely on ERA. During last week's drastic market fluctuations, he relied on the rapid confirmations and low fees on-chain, achieving nearly three times the daily returns compared to when he used other public chains. “I used to worry about missing opportunities due to on-chain congestion; now the execution speed is faster than market changes.”
In fact, cryptocurrency users want very simple things: professional technology hidden beneath the surface, and users only need an experience that is “fast, economical, and stable.” ERA hasn’t hyped any concepts; it simply uses a mature Layer 2 scaling solution to achieve a real balance of “high performance + high security.” The solid implementation of this technology is more persuasive than any promotion. #以太坊Layer2 $ERA
