The encryption process generates cryptographic keys that are used to lock (encrypt) and unlock (decrypt) data. There are two forms of encryption keys: symmetric and asymmetric. Key management providers, examples While many exchanges or custodians still operate a multisig cold wallet approach, there are now several key management providers on the market. Unbound Tech is…

Privacy on Ethereum is now possible through Aztec, a project using zero knowledge cryptography derived from Zcash to hide amounts for private tokens. The Aztec privacy network has officially launched on the Ethereum blockchain on Feb. 1. Using Zcash-based technology, it introduces confidential tokens where all amounts are cryptographically hidden. The network is currently in…

Triptych is a new ring signatures construction that could increase Monero’s anonymity set more than tenfold, though live implementations are still far off. The Monero Research Lab (MRL) has released Triptych in a Jan. 6 paper proposing trustless logarithmic-size ring signatures. As Monero’s core anonymity mechanism, research aimed at decreasing their size could improve the…
