Uncle Wang, who runs a second-hand bookstore in the community, has recently been troubled by tracing the origins of old books. 'Many customers want to buy rare books but are afraid of buying pirated copies. I want to put the transaction records of each book on the blockchain, but I've tried several chains, and either the information uploaded is hard to check, or the records from different years have to be looked up separately; or every time I update the owner information, the transaction fees are higher than the profit margin,' he said while stroking a yellowing poetry collection. 'How can a small bookstore endure such hassle?' @Caldera Official

This reminds me of ERA's 'on-chain archive' logic — it doesn’t store data in a 'scattered' manner like traditional public chains; instead, it uses a unified cross-chain protocol to integrate information from different periods and sources into 'coherent archives.' Just like Uncle Wang's old books, from the first edition printing, through various transfers to restoration records, no matter which chain they were originally on, they can be retrieved with a complete timeline in ERA with just one click. #Caldera

What’s more reassuring is that when updating information, there’s no need to pay extra for cross-chain operations. ERA automatically completes the 'seamless connection' between different chains, reducing transaction fees by nearly half compared to maintaining several separate chains. 'Just had an old customer check a 2003 essay collection, and with one click on ERA, he saw the notes from the previous two owners and bought it on the spot,' Uncle Wang said with a big smile. 'This technology truly helps small businesses retain customers.'

Those engaged in physical businesses understand that the quality of technology boils down to whether it can reassure old customers and make new customers feel at ease. ERA's ability to string together 'fragmented information' into 'trustworthy stories' precisely hits the pain points of small businesses: there’s no need to understand complex chains, as long as customers can consume with clarity, it is the best technology. $ERA
