Nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it
It is typical for a cryptographic technology to be useful in its primary goal and applications, yet to exhibit also a dark side, namely to allow abuses in some other situations.Learn more about Dark Side of Threshold Cryptography
Bitcoin — the world’s most popular cryptocurrency. In fact, the popularity of this digital currency is one of its biggest advantages against other players in the market.
As long as Bitcoin continues to dominate the cryptocurrency market, investors will always benefit from high liquidity levels. Even during periods of market uncertainty. Over the years, Bitcoin has shown a volatile yet consistent growth.
It is typical for a cryptographic technology to be useful in its primary goal and applications, yet to exhibit also a dark side, namely to allow abuses in some other situations. Examples are subliminal channels in strong (randomized) signature schemes, employing authentication for encryption, kleptography exploiting strong randomness, etc. Threshold cryptography was introduced to realize better security and availability. However, its “dark side” has never been addressed seriously. The result from users not possessing the entire private key due to threshold splitting is a deficiency which can hurt de-commitment in procedures like “contract signing” and nullify non-transferability properties.
To attempt solving the problem, one may suggest to assure that the user has full control of his private key via a zero-knowledge confirmation. However, advances in cryptography itself defeat this, since the Completeness Theorem for secure computations implies that servers in possession of shares of a key can answer on behalf of the “virtual holder” of the entire private key, without compromising the secrecy of their shares.
