Block's Bitkey: A Solution to Bitcoin's Inheritance Dilemma

Bitcoin, the world's first decentralized digital currency, has revolutionized the financial landscape. However, one persistent challenge remains: what happens to your bitcoin when you die? Block, the company behind the popular Cash App and Square, has introduced Bitkey, a self-custody bitcoin wallet, and now it's rolling out an inheritance feature to address this 'ultibillion-dollar problem waiting to happen.'



Bitkey's inheritance feature allows users to designate a beneficiary for their bitcoin holdings, ensuring a seamless transition of digital wealth to loved ones. This innovative solution addresses several pain points in bitcoin estate planning, making it simpler, more secure, and accessible for users.

Simplifying Legacy Transfers

Bitkey's inheritance feature simplifies the process of passing bitcoin to beneficiaries. Users can invite a designated beneficiary via the Bitkey app, creating an inheritance plan with a single invite link. Beneficiaries don't need to remember passwords or use complex instructions, making the process accessible to anyone, even those not technically savvy.



| | Bitkey Inheritance | Traditional Solutions |
|---|---|---|
| Setup | Simple invite link | Complex instructions or legal documents |
| Accessibility | Accessible to anyone | Requires technical knowledge |
| Control | Benefactor maintains control | Beneficiary may have access to wallet |
| Security | 6-month waiting period, multi-sig architecture | May lack robust security measures |

Key Security Measures

Bitkey's inheritance feature implements several key security measures to protect against accidental or fraudulent claims while balancing user control with beneficiary access. These measures include:

1. Six-Month Waiting Period: After a beneficiary initiates an inheritance claim, there is a six-month waiting period before the funds are made available for transfer. This waiting period allows the benefactor to cancel any accidental or fraudulent claims during this time.
2. Beneficiary Access Restrictions: Beneficiaries are not able to view or access their benefactor's Bitkey wallet, ensuring that the benefactor maintains control over their wallet and keys until the very end.
3. Multi-Signature Architecture: Bitkey's multi-signature architecture splits custody among three keys, ensuring users retain control—even if Block were to go out of business. This architecture extends to the inheritance feature, providing an additional layer of security.

Advantages for Users

Bitkey's inheritance feature offers several advantages over existing solutions provided by other self-custody wallets and traditional financial institutions. These advantages include:

1. Simplicity and ease of use: Inheritance is set up through the Bitkey app by designating a beneficiary, who receives an invite link. No complicated legal documents or lengthy seed phrases are required.
2. Control and privacy: Beneficiaries cannot view or access their benefactor's Bitkey wallet, ensuring control and privacy for customers until the very end. Wallet owners can change their beneficiary at any time.
3. Security: Bitkey's multi-signature architecture ensures that funds are secure and can only be accessed with the correct keys. The 6-month waiting period and regular notifications to the wallet owner provide an additional layer of protection against accidental or fraudulent claims.

Bitkey's inheritance feature is a significant step forward in addressing the challenges faced by bitcoin holders when it comes to estate planning. By offering a simple, secure, and accessible solution, Bitkey is making it easier for users to pass their bitcoin to loved ones, ensuring that their digital wealth continues into future generations.
