Nunchaku, the Bitcoin-only wallet, announced version 2.0, an update that introduces “autonomous inheritance.”
The feature is described as “the first Bitcoin-backed inheritance solution with an on-chain backup system, designed to outlast the company that created it.”
In other words, with the new system published on November 12th, Establish an automated mechanism to transfer funds In case of death of a user, loss of access or disappearance of the developer.
This proposal aims to solve a historical problem in the ecosystem: what happens to Bitcoin (BTC) if its owner loses access to it.
How can I automate Bitcoin transactions?
Nunchuk combines two Bitcoin technologies to implement automatic inheritance. mini script and time lock In chains.
on the one hand, mini script A language that allows structuring in a safe and flexible way Conditions for using Bitcoin,on the other hand, time lock These set temporary deadlines that must be met before a transaction is valid.
By integrating both tools, Nunchuk allows you to pre-program what will happen with your funds. If a certain period of time passes without any operation from the ownerthese can be automatically forwarded to the address designated as the heir.
However, access to the auto-inheritance feature is paid for in nunchaku, with a current value of $480.
Bitcoin wallet that causes multiple innovations
Additionally, Nunchuk 2.0 introduces other features within the Bitcoin ecosystem, as explained by the founder known as Hugomofn at X.
Among them, according to the founders, Nunchaku will be the first multi-signature wallet (multisig) and multi-user, i.e. Multiple people can share the same wallet Under multiple signature schemes.
This type of configuration requires the following Multiple private keys validate transactionsincreasing security against theft and unauthorized access.
Meanwhile, a signature was also added to the wallet using a technology called NFC (near field communication). Transactions can be approved by bringing a compatible device closer togethersimilar to the TAPSIGNER card.
Finally, Nunchuk 2.0 also adds unique end-to-end encryption. This means that the data is encrypted on the user’s device and It will only be decrypted in the recipient’s environment.Even intermediate servers will not be able to access plain text content. The founders explained that they rule out external solutions like Matrix.
