Vitalik Buterin's Emphasis on Multisig for Asset Protection
On May 1, 2024, Ethereum co-founder Vitalik Buterin revealed that he manages over 90% of his personal assets using a multisignature system.
Multisig requires multiple signatures for cryptocurrency transactions and disperses control among several parties, which prevents theft even if one private key is compromised.
This statement was made during a discussion about the use of hardware wallets for storing cryptocurrencies. Buterin supports the view that "using a hardware wallet makes yourself a risk" and suggests that "using multisig is essential to decentralize one's own security."
Understanding "M-of-N" in Multisig
Buterin's mention of "M-of-N" refers to a system where, out of "N" total keys, "M" keys are required to perform a transaction.
For example, a "3-of-5" setup means that while there are five different keys, at least three are needed to authorize a transaction.
This arrangement is particularly valuable in cryptocurrency exchanges and foundations that manage significant assets, as it requires at least two private keys to attempt theft, thereby substantially reducing the risk.
Multisig not only mitigates the risks associated with the loss of a private key—by allowing other keyholders to access the assets—but also addresses various risks associated with self-management.
However, choosing truly trustworthy members is crucial, as the effectiveness of multisig depends on the reliability of the keyholders. While multisig might not be suitable for everyone, it is worth considering for those seeking a more secure asset management method.
