For inheritances, Nunchuk uses two native Bitcoin technologies: miniscript and timelocks.
The update also introduces NFC signing, coin control and end-to-end encryption.
Nunchuk, an exclusive wallet for Bitcoin, presented its version 2.0, an update that introduces “autonomous inheritances.”
This feature is described as “the first Bitcoin assisted inheritance solution with an on-chain backup system, designed to outlive the company that created it.”
In other words, the new system, published on November 12, allows establish an automatic mechanism to transfer funds of a user in the event of death, loss of access or disappearance of the development company.
The proposal aims to solve a historical problem of the ecosystem: what happens to bitcoins (BTC) when their owner can no longer access them.
How is it possible to automate transactions in Bitcoin?
Nunchuk manages to implement automatic inheritance by combining two Bitcoin technologies: miniscript and the timelocks in chain.
On the one hand, miniscript It is a language that allows structuring in a secure and flexible way the conditions under which bitcoins can be spentwhile the timelocks They establish temporary deadlines that must be met before a transaction is valid.
By integrating both tools, Nunchuk allows plan in advance what will happen with the funds if a certain amount of time passes without any activity from the ownerallowing these to be automatically transferred to the addresses designated as heirs.
However, access to the automatic inheritance function is paid in Nunchuk, with a worth current $480.
A Bitcoin wallet that inaugurates multiple innovations
In addition, according to explained Its founder, known on X as Hugomofn, Nunchuk 2.0 introduces other features within the Bitcoin ecosystem.
Among them, according to the founder, Nunchuk would be the first multi-signature wallet (multisig) and multi-user, which means that several people can share the same wallet under a multiple signature scheme.
That type of configuration requires that more than one private key validate a transactionwhich increases security against theft or unauthorized access.
On the other hand, the wallet also added signatures using NFC (near field communication), a technology that allows you to authorize transactions by bringing compatible devices closerlike the TAPSIGNER card.
Finally, Nunchuk 2.0 also added its own end-to-end encryption, that is, data is encrypted on the user’s device and They are only decrypted in the recipient’swithout even the intermediate server being able to access the plain text content. The founder explained that they ruled out external solutions like Matrix.
