A decentralized ledger, also known as a “blockchain”, is a relatively new type of cryptographically protected database. Each entry in the database is called a “block”. Each block is run through a cryptographic algorithm to produce a string of data called a hash. The hash of each block is placed in the following block, creating a chain of blocks. If any data is changed in a block, then the hash of the block and every subsequent block changes too, breaking the chain and exposing the change. This ensures that the database is append-only, tamper-proof, and auditable with a high degree of confidence.

Let’s explore some of the advantages decentralized ledgers have over a centralized databases.

Central authority: all participants trust a single central authority to manage and convey information accurately

No audit trail: can be altered without detection

Single point of failure: if the clearing house goes down everyone loses access to the data

Required to be online 24/7: forces a high-availability guarantee and increases ecosystem costs


No central authority: participants rely on consensus to make decisions, each preserving their own authority

Tamper-proof and auditable: cryptographic ledgers are immutable; they provide high-integrity, robust, dependable data

Lower maintenance cost: decentralization and cryptography increases cost sharing and resiliency in the face of failure

Offline access: cryptography ensures the accuracy of data, allowing it to be accessed from anywhere, not just the original source; can circumvent Internet outages

Veres is developing fit-for-purpose blockchain technology that addresses digital credentialing problems in areas such as first responder identification, verifiable prescription writing, retail fraud, and hazardous material information sharing. Fit-for-purpose blockchains augment Issuers, Wallets, and Verifiers to increase the availability and auditability of digital credentials.


Veres Ledger’s design and use of open standards enables it to be seamlessly combined with Veres’s credentialing software or with other custom built applications.
