三星申请智能合约数字资产钱包专利：设备无需私钥即可发起加密交易

三星电子已在美国提交了一项关于数字资产钱包系统的专利申请。该系统利用智能合约，允许设备在无需直接存储或使用私钥的情况下发起加密货币交易。

核心机制：智能合约接管部分交易流程

根据该专利申请，三星提出了一种新的系统架构，旨在将钱包的部分功能从单一设备转移到区块链网络上的智能合约中。这一设计旨在降低用户直接在各个设备上管理敏感信息（如私钥）的需求。

在处理数字资产交易之前，系统会通过智能合约验证设备的指定地址和认证信息。虽然私钥并未完全从系统中消失——最终的加密货币交易仍可能依赖于智能合约的区块链地址和私钥——但发起交易的设备本身无需持有或使用该私钥。这种机制使得设备能够在不提供区块链地址及由私钥生成的签名的情况下发起交易。

多设备协同管理同一钱包

三星的这项专利不仅限于单设备交易。其提出的结构允许智能手机、计算机、可穿戴设备以及家用电器等多种电子设备共同参与管理同一个数字资产钱包。

In the system, multiple electronic devices can collaborate to create, change, or restore addresses used for cryptocurrency transactions. For example, one device can request to initiate a transaction, while another device supports functions such as registering a new device or restoring an address. The newly generated address and its authentication information are then registered into the smart contract.

Technical background and integration with existing ecosystems

Traditional self-managed wallets usually require users to strictly protect private keys, because losing the private key will make funds inaccessible, and leaking the private key may lead to assets being controlled by others. Samsung points out in its patent that managing such secure information is one of the limitations of the existing wallet structure. At the same time, delegating information to service providers carries separate risks, such as if the service provider is hacked or ceases to operate.

The multi-device structure proposed this time is based on Samsung's early results in connecting blockchain functions with consumer hardware. For years, its Galaxy smartphones have supported "Samsung Blockchain Wallet" and "Blockchain Keystore". Previously, by integrating Ledger wallets, users could already manage assets stored in hardware wallets that support the service through Galaxy devices.

Samsung continues to add digital asset services to its mobile ecosystem. In 2025, the company will connect Coinbase to Samsung Wallet in the United States, providing approximately 75 million Galaxy users with access to cryptocurrency services through their wallets.

Stability coin support and future outlook

随着三星致力于扩展三星钱包中的数字资产功能，该专利的申请恰逢其时。此前报道指出，三星于今年7月宣布计划为钱包添加稳定币支持。公司在Galaxy Unpacked发布会上表示，该服务最终将在现有的支付、奖励和数字资产功能之外，支持稳定币。

然而，三星尚未透露将支持哪些稳定币或区块链网络，也未提供具体的发布日期或技术合作伙伴信息。此外，三星证券、三星SDS和三星卡等关联公司近期在韩国探索相关基础设施，曾同意以约6128亿韩元（约合4.08亿美元）的价格收购Upbit加密交易所运营商Dunamu合计4%的股份。三星SDS随后将稳定币基础设施确定为与Dunamu合作的初始领域，讨论内容涵盖区块链基础设施、基于人工智能的支付以及涉及虚拟资产的金融系统。
