The 'old problems' of blockchain are just a few: slow, expensive, cross-chain difficulties, and complex development. However, the chains under Caldera have cumulatively processed 750 million transactions, and behind this number, these 'problems' are being gradually resolved.

First, let's talk about 'speed'. A transaction on the Ethereum mainnet takes an average of 15 seconds, and during peak times, it can be delayed for hours. In contrast, Caldera's chains optimize the Rollup mechanism, allowing for an average confirmation time of 3 seconds, and some payment chains even achieve 1-second settlement, which is almost as fast as swiping a credit card.

Now let's look at 'cost'. Last year, Ethereum transfer fees peaked at dozens of dollars, but now Caldera's chains average only $0.1, and some chains even offer free transfers during promotions (subsidized with ERA tokens). Regular users are finally willing to make frequent transactions, leading to the 750 million transaction volume.

No more worries about 'cross-chain difficulties'. Previously, transferring coins from Chain A to Chain B involved remembering 5 steps and paying 3 transaction fees. Now, with the metal layer, it can be done with just a click, and the cost is reduced by 60%. Data shows that chains integrated with the metal layer have cross-chain transaction volumes 3 times higher than those that are not.

Complex development? Not at all. A certain team built a DeFi chain from scratch using Caldera's toolkit; 3 technical personnel completed it in 2 weeks. In the past, it would have required at least a 10-person team working for 3 months.

These changes are the significance behind the 750 million transactions—blockchain is finally starting to become 'user-friendly'.
