German Bitcoin developer says that due to concerns about private key management and the security risks of self-hosting, he was unable to hold more BTC. This statement came after a new round of discussions about self-hosting was sparked by a vulnerability in Coldcard.

比特币研究员、闪电网络开发者 René Pickhardt 表示,自己一直认可比特币的长期前景,但始终没有大量买入,主要原因不是看空,而是担心自托管过程中的安全和私钥管理问题。

开发者谈未重仓原因

Pickhardt 在 X 上表示,自己过去一直不太愿意公开真正原因。按他的说法,即便私钥生成本身没有问题,后续存储方式、软件缺陷,以及未来技术变化,都可能让资产保管面临风险。

这番表态引发不少用户共鸣。对普通持币者而言,自行保管比特币意味着更高控制权,但也需要独自承担密钥丢失、设备故障和操作失误等后果。

Coldcard 漏洞导致被盗

相关讨论出现在硬件钱包安全事件持续发酵之际。近期,Coldcard 被曝出随机数生成实现存在漏洞。研究人员称,在特定条件下生成的钱包助记词可能变得可预测,攻击者因此有机会重建私钥并转走资产。

安全研究人员表示,这一问题与生成助记词时使用的随机数生成器实现有关。相关实现从设备序列号等可预测信息中提取熵,降低了密钥随机性。

  • 被盗规模超过 1,755 枚 BTC
  • 文中估值超过 1 亿美元
  • 个别受害者损失约 160 万美元

自托管门槛再受关注

事件曝光后,围绕是否应自行保管比特币的讨论再次升温。支持者认为,自托管仍是比特币去中心化理念的重要部分,但前提是用户具备足够的安全意识和操作能力。

Blockstream 首席执行官 Adam Back 回应称,持有这类资产意味着更高责任,关键在于不要丢失私钥。也有观点认为,Pickhardt 对密码学本身的担忧并不完全准确,但这并未削弱市场对自托管门槛的关注。

这起事件再次显示,影响比特币采用的不只是价格波动,资产保管体验和安全工具的可靠性,同样会左右用户是否愿意长期持有。
