In the wake of a Cold Card vulnerability that TRM Labs put losses from at 1,816 BTC, or more than $100 million, multi-signature wallets have taken on new importance as a means of protection for Bitcoin users. The subject of the most recent Crypto Tips is how such a wallet can be a bulwark against the kind of ruinous loss that hardware flaws can bring about.<\/p>\n
The numbers are telling: TRM Labs, one of the leading blockchain analytics firms, has put the figure at 1,816 BTC lost in the Cold Card firmware incident, well over $100 million by today\u2019s reckoning. It was a sobering reminder to those who use hardware wallets that exploitable defects can be found even in devices one trusts. Those who made the Cold Card their only repository for private keys left all their funds open to a single point of compromise.<\/p>\n
Crypto Tips\u2019 host makes clear that the whole point of a multisig is to have several independent keys sign off before a transaction goes through. A single key or device being compromised will not suffice to access the assets, and so the danger of losing them altogether is much diminished. With the Cold Card problem, having two of its keys in your multisig would not have been enough if both were rendered vulnerable. What gives a multi-signature wallet its strength is the ability to have keys in the hands of different people or on other devices; should one fall, the rest hold the line.<\/p>\n
A multisig can be set up in a number of ways. One might have all three keys oneself, or cede a third to someone trusted while keeping two. Some go for something more elaborate like a \u2018three-of-five\u2019 with a key on a smartphone or given to a company. But the host of Crypto Tips suggests that the prudent course is to have each key with a separate individual or on a distinct device to preclude any chance of them being compromised at once.<\/p>\n
It is not without its demands; putting in place a multi-signature wallet entails an extra measure of management and the secure storage of the various keys so as not to be without the necessary threshold to act on them. Yet the complexity is offset by the resilience it affords where single points of failure are concerned, no small thing when one has considerable cryptocurrency to look after.<\/p>\n
And as was made plain in the Crypto Tips conversation, a multisig lets a user be their own custodian without the need for a third party, in keeping with the decentralization that is crypto\u2019s ethos. By diffusing the authority to sign, one is better shielded from misfortune or an outside attack, which is why it is fast becoming the standard for any serious holder of Bitcoin.<\/p>\n
