However, these passwords often lacked complexity and the wallets themselves were vulnerable to malware and spyware attacks that could easily extract those credentials.

To combat this vulnerability, encrypted wallets were introduced. Encryption involved securing the wallet with a cryptographic key, making it considerably harder for unauthorized users to gain access if they did not possess the key. This was a significant step forward in protecting users’ private keys, the strings of data that prove ownership of the digital coins.

First Exchange Security Practices

As cryptocurrencies began to gain traction, the need for exchanges where users could buy, sell, or trade cryptocurrencies became apparent. Early exchanges, however, were often makeshift and lacked robust security protocols, making them prime targets for hackers.

One of the first security practices implemented by exchanges was two-factor authentication (2FA). This system required users not only to enter a password but also to verify their identity through a second method, typically a text message or email containing a code. This added an extra layer of security, as accessing an account would require both the password and access to the second authentication factor.

Another critical security measure adopted early on was the use of cold storage for the bulk of the assets managed by exchanges. Cold storage refers to keeping cryptocurrencies offline, away from any internet connection, thereby insulating them from online hacking attempts. Only a small percentage of assets would be kept in “hot wallets” for daily transactions, minimizing potential losses if security breaches occurred.
