Bitcoin's Evolution: From Digital Gold to Financial Instrument

According to Cointelegraph, Bitcoin (BTC) has long been regarded as "digital gold," held securely in wallets and rarely utilized. However, this perception may be shifting, as discussed by StarkWare’s Bitcoin lead, Ilia Volokh, on a recent episode of The Clear Crypto Podcast. Hosts Nathan Jeffay and Gareth Jenkinson explored the potential transformation of Bitcoin from a static store of value to a dynamic financial instrument. The discussion highlighted how innovations such as wrapped Bitcoin and trustless bridges could unlock new applications for the cryptocurrency. Volokh compared the traditional view of storing gold under a mattress to the current use of Bitcoin, suggesting that while gold cannot multiply in such a scenario, Bitcoin's potential is less clear-cut. The primary challenge lies in Bitcoin's base protocol, which was designed with limited functionality, unlike Ethereum (ETH) or Solana (SOL), which support smart contracts and decentralized finance (DeFi) applications. Despite this, there is a growing demand for Bitcoin to offer similar functionalities. Jenkinson noted that while people are eager to utilize Bitcoin in new ways, the current limitations prevent extensive use. Volokh, however, is optimistic about the near future, where technological advancements may enable diverse applications for Bitcoin. One such innovation is "wrapped Bitcoin," which allows users to deposit BTC with a trusted entity that issues a tokenized version on another blockchain, such as Ethereum. This method, however, involves relinquishing custody, a concept that many Bitcoin enthusiasts oppose. To address these concerns, the development of trustless or low-trust bridges is underway. These tools enable Bitcoin holders to engage with DeFi protocols without losing control of their assets. Although truly trustless solutions would necessitate protocol changes, such as implementing the OP_CAT opcode, Volokh acknowledges the cultural resistance within the Bitcoin core community that makes such changes unlikely. Nonetheless, hybrid approaches are gaining popularity, particularly for real-world applications like borrowing dollars against Bitcoin and generating yield through BTC "vaults" managed by third parties. These methods are already being utilized on a large scale, connecting Bitcoin's substantial capital to broader financial systems.
