A soft fork is a backward-compatible update to a blockchain protocol. This means that nodes that haven’t updated the software can still process transactions, but may not be able to fully participate in the new features of the network. Soft forks are typically used for minor improvements, like reducing block size or adding new features without disrupting the network. A hard fork, on the other hand, is a permanent and incompatible change that results in a split into two separate blockchains. For example, Bitcoin Cash was created after a hard fork from Bitcoin, as it implemented a larger block size limit that Bitcoin’s network did not adopt.

The rise of algorithmic stablecoins like TerraUSD challenges traditional fiat-backed stablecoins by offering decentralized alternatives that rely on algorithms rather than asset reserves. Unlike fiat-backed stablecoins such as Tether, which depend on centralized custodians and face transparency issues, algorithmic stablecoins aim for stability through supply adjustments, reducing reliance on traditional financial systems. However, their rewards—decentralization and capital efficiency—come with significant risks. TerraUSD’s 2022 collapse, erasing over $40 billion, exposed vulnerabilities to speculative attacks and market instability when under-collateralized. While fiat-backed stablecoins risk centralization and regulatory scrutiny, algorithmic stablecoins’ fragility fuels market volatility, prompting calls for stricter regulations and hybrid models blending stability with innovation.
