TON's Challenges and Limits: A Critical Analysis of Scalability, UX, and Adoption

The TON blockchain system may require managing dozens of asynchronous messages with manual error handling at every step, which complicates achieving atomicity in transactions. HotStuff and its derivatives enable a deterministic, linear ordering of blocks at high finalization speeds, providing a clear foundation for optimistic parallel execution techniques like Block-STM. The virtual machine detects conflicts during execution and replays only necessary parts, allowing developers to write code as they would for a monolith, with the system extracting parallelism safely. In contrast, every decentralized application on TON must explicitly manage state, messages, and errors amid the chaos of asynchronous operations. Practically, complex protocols—such as those involving liquidity pools—hit a single shard capacity limit, which currently leads to putting entire protocols or tokens into one shard. This challenges the original scalability idea, marking a bitter irony. The value of DeFi lies in composability, yet on TON, this becomes nearly impossible without bespoke vertical integrations. Features like flash loans are either unfeasible or require immense effort, resulting in centralized intermediaries that undermine blockchain trust. TON aims to be a blockchain for mass adoption, competing with Solana, Aptos, Sui, Hyperliquid, MegaETH, and Arbitrum—boosted by speed, low cost, and seamless UX. However, TON falls short in every respect: transaction speeds are slow (minutes for complex operations), costs are significantly higher than competitors, and the user experience is convoluted—exemplified by the perplexing "wallet-in-wallet" design. While slower and pricier, TON could find a niche among institutional users if it shifted to a different positioning with higher decentralization. The narrative that TON’s strength lies in Telegram integration and its vast user base oversimplifies reality. The Telegram native traffic is toxic and unconvertible into meaningful DeFi activity, with a core access point through @wallet for only select projects, limiting exposure. The real on-chain audience is small and limited, mostly engaging in off-chain activities like tap-to-earn promotions and Telegram gifts, but struggling to convert this activity into on-chain assets or liquidity. Successful adoption thus relies on off-chain engagement rather than on-chain infrastructural growth. Support and grants reveal a challenging economy where projects often pay to bring users into someone else’s ecosystem, building infrastructural "roads" that lead to centralized platforms instead of community trust. Once users arrive, they seek out centralized exchanges, meme coins, and games—focused on central hubs, not the open decentralized ecosystem—thus diminishing the promise of a truly open blockchain.
