Zakura said its new cryptography library for Zcash has improved proof-generation performance on mobile devices by more than 14 times, reducing wallet transaction creation from more than 3 seconds to under 200 milliseconds in some cases, according to information shared by @CoinMarketCap on X.

The reported improvement targets one of the computational processes involved in creating Zcash transactions. By reducing the time required to generate cryptographic proofs, the library could make transaction creation substantially faster on mobile devices in cases where the stated performance gains are achieved. The development focuses on the underlying cryptographic software used to support Zcash-related wallet operations rather than on changes to the Zcash network itself.

Zakura Reports Faster Mobile Zcash Proof Generation

Zakura said its new library significantly accelerates proof generation on mobile hardware. In some cases, the time required to create a wallet transaction has fallen from more than 3 seconds to less than 200 milliseconds — a reduction of more than 14 times based on the figures provided in the update.

Proof generation is an important component of privacy-oriented cryptocurrency transactions. Cryptographic proofs allow a transaction system to verify that required conditions have been satisfied without necessarily revealing all of the underlying information. Zcash's shielded transactions rely on zero-knowledge proof constructions, and the network's proof systems have evolved across major protocol upgrades — most recently with the Halo 2 proving system introduced in the Network Upgrade 5 (Nu5) upgrade. The computational requirements associated with these operations can be particularly relevant on mobile devices, where processing resources and battery efficiency can differ from those available on desktop computers or dedicated infrastructure.

Faster Transaction Creation Could Improve Mobile Wallet Performance

The reported performance gains are focused on transaction creation within wallets. Reducing the time required for cryptographic processing can shorten the period between a user initiating a transaction and the wallet completing the necessary calculations. Zakura said the improvement brings transaction creation below 200 milliseconds in some cases, compared with more than 3 seconds previously.

The figures provided do not indicate that every mobile device or every transaction would experience the same performance improvement. Instead, the claim applies to some cases described in the update. Performance can vary depending on factors such as device hardware, software implementation, and the computational requirements of individual cryptographic operations. The available information does not provide additional testing conditions or technical benchmarks. Independent verification of the claimed figures has not been reported; the numbers reflect Zakura's own statements as relayed by CoinMarketCap.

Zcash Cryptography Remains Central to Privacy Features

Zcash is a cryptocurrency designed with privacy features that rely on advanced cryptographic techniques. Its transaction system uses zero-knowledge proof technology to enable certain transactions to be verified while protecting selected transaction information. The project is backed by the Electric Coin Company, the original developer of the Zcash protocol, and has a history of cryptography research feeding into its wallet software.

Cryptographic proof generation can require significant computational resources, making optimization an important area for software developers working on Zcash wallets and related applications. A dedicated cryptography library can provide developers with optimized implementations of these calculations. In the case of Zakura's latest release, the stated objective is to make proof generation substantially faster on mobile devices.

The reported change from more than 3 seconds to under 200 milliseconds represents a shift in processing time that could be particularly relevant to applications where users expect transactions to be prepared quickly. Sub-200-millisecond transaction creation approaches the responsiveness users typically expect from conventional payment applications, which has historically been a difficult bar for privacy-preserving cryptocurrency wallets to meet on mobile hardware.

Mobile Optimization Becomes Increasingly Important

As cryptocurrency wallets are increasingly used on smartphones and other mobile devices, software performance can influence how efficiently transactions are created and processed. Computationally intensive cryptographic operations can create bottlenecks when performed on devices with limited resources, and optimizing those operations can reduce the time required for applications to complete transaction-related calculations.

Zakura's reported results therefore focus on a specific technical challenge within the Zcash ecosystem: improving the speed of cryptographic proof generation on mobile hardware. A next step for observers would be independent benchmarking or adoption of the library by Zcash wallet developers, which would provide outside confirmation of the reported gains.

According to @CoinMarketCap, Zakura's new Zcash cryptography library makes mobile proof generation more than 14 times faster, with wallet transaction creation falling from over 3 seconds to under 200 milliseconds in some cases. The reported performance improvement represents a software-level optimization aimed at reducing transaction creation times and improving the efficiency of cryptographic operations on mobile devices.
