Blockchain / DLT
A blockchain is a distributed ledger: an append-only record replicated across nodes, where transactions are batched into cryptographically linked blocks and consensus rules — not a central operator — decide the shared state.
Public vs permissioned
Public networks (Bitcoin, Ethereum, Stellar) let anyone run a node and validate; consensus is economic (proof-of-work, proof-of-stake, federated voting). Permissioned networks restrict who validates — better suited to consortia and regulated data exchange, which is why infrastructures like EBSI chose that model. The trade-off is decentralization and censorship resistance versus throughput, privacy, and known validators.
Either way, the enterprise value is the same: a shared, tamper-evident state that all parties trust without trusting each other — useful wherever multiple organizations need one version of the truth: payments, credentials, provenance, settlement.
Enterprise adoption and standards
Adoption moved from pilots to infrastructure: payment settlement on Stellar, EU-wide credential registries on EBSI, and tokenized assets under MiCA. International standards are catching up — ISO/TC 307 publishes DLT vocabulary and architecture standards, W3C standardized DIDs and verifiable credentials, and ISO 20022 mapping lets DLT systems interoperate with bank rails. Our publications on cross-border payment standardization cover this space.
