While other chains have cleverly navigated around the limitations of distributed ledgers, [Solana](https://www.gate.io/learn/articles/vanecks-base-bear-bull-case-solana-valuation-by-2030/1111 "Solana") chooses to push the limits of technological feasibility and explore from there. In the Bitcoin realm, [Mint Cash](https://www.gate.io/learn/articles/what-is-mint-cash/1127 "Mint Cash") proposes a decentralized payment and savings system collateralized by Bitcoin, redesigning the Terra protocol through an innovative currency stability model based on a trusted economic system.
