Beyond technical architecture challenges, the Web3 ecosystem faces serious user experience problems, which have become one of the biggest obstacles to mass adoption. Compared to the simple and intuitive interfaces refined over twenty years in the traditional Web2 ecosystem, Web3 introduces numerous concepts that are unfamiliar and complex to ordinary users, creating a steep learning curve that keeps hundreds of millions of potential users at bay.First, while the gas fee mechanism is technically reasonable and necessary (preventing the network from being flooded with spam transactions and providing economic incentives for miners/validators),it is counterintuitive for ordinary users. In the Web2 world, operating costs are borne by service providers and indirectly recovered through advertising, subscriptions, or data monetization, with users enjoying an apparently ”free” experience. In Web3, users need to pay directly for each operation and must understand the subtle difference between gas limit (upper limit of computational steps)and gas price (cost per computational step). More confusing still, even when transactions fail for various reasons (possibly due to excessive slippage, contract execution errors, or improper gas limit
settings), users still need to pay the consumed gas fees. This experience of ”paying for failure” is difficult for users accustomed to Web2 services to understand and accept.Second, while the concept of self-custody wallets grants users true asset sovereignty (”Not your keys, not your coins”), it also brings enormous responsibility and risk. Unlike the centralized account systems managed by service providers in Web2, Web3 requires users to understand the cryptographic relationship between public and private keys, properly safeguard mnemonic phrases consisting of 12 to 24 words, and deeply understand that once private keys are lost or leaked, funds will be permanently lost with no recovery possible. There is no ”forgot password” reset option, no customer support to appeal to, and the irreversibility of transactions means that misoperations can cause huge losses. While these characteristics embody the essence of decentralization and autonomy, they represent enormous psychological burden and actual risk for ordinary users.Furthermore, the complexity of the multi-chain ecosystem further exacerbates user confusion.Different blockchains adopt different address formats (Ethereum’s 0x-prefixed addresses, Bitcoin’s various address formats, Solana’s Base58 encoding, etc.), different fee structures (Ethereum’s gas,Solana’s rent, Cosmos’s multi-token fees, etc.), and different interaction methods. Users need to manage multiple wallets, remember multiple sets of mnemonic phrases, understand the characteristics of each chain, and master how cross-chain bridges work and their potential risks. When users want to transfer assets from one chain to another, they need to find reliable cross-chain bridges, pay double fees, wait for long confirmation times, and bear technical risks in the bridging process. This fragmented experience contrasts sharply with Web2’s unified account system—where one Google or Facebook account can log into thousands of applications—severely hindering mainstream user entry.
