BLOCKY APIs offer several benefits when compared to other blockchain-based approaches to securing data.


  • Because BLOCKY signs data onto the Ethereum blockchain, your signatures complete in under 30 seconds with timestamps that are precise to 10 seconds. BLOCKY achieves these efficiencies because of Ethereum’s shorter block times which minimize the duration of writes and keep timestamps accurate. This is significantly faster and more precise than signatures on the Bitcoin network, where signatures can take more than an hour with timestamp precision of 10 minutes.

  • Most similar systems are exclusively cloud-based; however, our API backend can be deployed in the cloud or on your premises, allowing us to white label our API so you can seamlessly integrate BLOCKY’s products into your own.

  • We charge for file signatures but allow our clients to perform verification for free, making it easy to share signed data with your partners, who can verify data without having a contract with BLOCKY. And client-based verification means that you can continue to verify your data in perpetuity.

  • We protect your data with secure SHA3 hashes, while most similar systems use the less secure SHA256 hashes.
