Blockchain security solutions
As the world gradually realizes that cryptocurrencies, tokenized assets and smart contracts are the new Wild West of financial instruments, new threats emerge. Regulatory pressure and cybersecurity risks are harder to mitigate when your technological stack is novel and based on new cryptography-based technologies. Our solutions facilitate compliance with regulations such as the GDPR, CCPA and the completion of Privacy Impact Assessment (PIA), Data Protection Impact Assessment (DPIA).
Cryptocurrencies require combining novel cryptography with traditional data, application and product security expertise to address blockchain security issues.
Blockchain security challenges
Blockchain security is hard
With only a little more than a decade in the making, the cryptocurrency industry still lacks foundations of "acceptable security" and people with considerable experience in both traditional security and "cutting edge" developments.
Poorly implemented crypto and appsec
Components of cryptocurrency systems, in particular, non-custodial wallets and blockchain nodes, require appsec and datasec measures to protect stored data, prevent unauthorized transactions, and stop malicious users.
Transaction and smart-contract privacy
Building cryptographic protocols that enable efficient transaction and smart-contract privacy is hard and requires specialized technical knowledge and an expert team.
Scalability
To make the current generation of blockchain systems scalable and fast, novel cryptographic solutions that balance security with understanding how the system will run globally under millions of transactions are required.
Modern blockchain security solutions
ZKPs: SNARKs, SNORKs, STARKs
Non-interactive zero knowledge protocols enable many essential properties in blockchains. Designing instrumentation around them is complicated but crucial.
Traditional security
Blockchain systems often need to combine novel cryptography and traditional application security measures.
Custom cryptosystems and primitives
Blockchains rely on a number of custom cryptosystems and crypto-primitives, which enable scalability and integrity.

How we make a difference
Cryptographic expertise
We employ experts with a traditional academic and practical background in cryptography. We maintain open-source cryptographic libraries and share our applied research in whitepapers.
Experience with typical constructions
We have developed production-ready zk-SNARKs implementations, private transactions, multi-signature schemes, and other blockchain-specific cryptosystems.
Real-world crypto
Along with our good niche expertise in blockchain, we have also implemented and secured cryptographic controls in many instances, from building end-to-end encrypted applications to DRM-like ML protections.
Our mission is simple.
We help you focus on serving your customers better, while relieving your team of security engineering burdens and giving your users confidence that their data is safe with you.
