Crypto was born from an open-source ethos, where code was shared publicly, accessible for review and shaped by community contributions. Transparency and verifiability are foundational principles that enable trust in Bitcoin.
But as the space matured, some disadvantages of open source surfaced. Innovative smart contract platforms and decentralized finance (DeFi) applications were forked to create direct competitors — from the wave of Uniswap clones to Ethereum forks — which prioritized speed and lower fees over decentralization.
As a result, some projects opted for closed-source development to protect proprietary designs and reduce the risk of exploits, hoping to delay or deter malicious actors by making the code harder to analyze. This approach is often criticized as “security through obscurity,” where hiding vulnerabilities instead of fixing them becomes a line of defense.
Closed-source systems run counter to crypto’s original vision of decentralization and transparency. What started as a grassroots movement among cypherpunks and hackers is now increasingly mainstream and integrating with the very institutional system it once sought to disrupt.
Solana Loopscale exploit shows why open source can still be more secure
An exploit on Solana’s Loopscale protocol shows that closed source is not a one-size-fits-all solution for keeping malicious actors out. On April 26, just weeks after launching, the closed-source DeFi lending platform suffered a $5.8-million exploit.
