Blockchain Security

Independence Is Essential


With disintermediation comes reduced support and increased risks of personal compromise. In a public context, there is no backup plan or password reset. If you drop your wallet on the sidewalk, you lose your money. Similarly, if you don’t look after your house keys or private keys, it could result in being irrevocably locked out.

Especially in public environments, proper key management is incredibly important. If your project is running on a public blockchain, a compromised key could mean having your funds hijacked, or smart contracts compromised. Currently, there is little in the way of “undo” functionality for these types of scenarios. In private blockchains, an ecosystem where there may be a greater degree of control, it’s still very important to ensure that information can still be securely added and stored on the chain. In the same way that it’s important for users to secure their passwords for personal accounts, they should ensure that their keys are stored securely and backed up to minimize risks of being lost or inaccessible.

In the case of decentralized applications, this means that there is always a risk that your organization could lose control of a smart contract or other assets if the keys are lost, and there is no recourse. As a result, it is always recommended to consult with technical experts prior to engaging in any on-chain business or when dealing with large amounts of cryptocurrency. They can help ensure that proper recovery techniques are in place including multi-signature shared control.
