Bithumb Applies Multi-Sig Technology to Its System


Bithumb is applying Multi-sig technology that is adopted by major companies to prevent security weaknesses in advance and to tighten up its security to protect its customers’ assets.
According to industry, Bithumb is applying Multi-sig technology that applies multiple encrypted keys that are necessary for cryptocurrency transactions.
Current cryptocurrency security method provides only one encrypted key. As a result, encrypted keys that are stored within accounts are vulnerable to being stolen when a cryptocurrency exchange faces an outside attack. On the other hand, Multi-sig technology requires two keys out of three personal keys to open a cryptocurrency wallet and it can prevent an access on assets from an outside attack even when an exchange is going under bankruptcy or has its server hacked.
Multi-sig technology, which is the most certain method for protecting cryptocurrencies, is also highly recommended by information protection authorities to relevant industries.
Because Multi-sig system requires application of difficult IT security technologies and large investments, there are only but few global cryptocurrency exchanges that have adopted such system.
Bithumb recently started providing technical support regarding Smart Contract deposit process to those exchanges that are having difficult times with Multi-sig technology.
Methods that utilize Smart Contracts to send cryptocurrencies are currently generalized. However, some cryptocurrency exchanges are having difficult times with handling assets due to lack of internal programs for sending Smart Contracts.
By applying Multi-sig technology, Bithumb has been able to take preemptive actions against AML (Anti-Money Laundering) issue as well.
