Transactional Integrity Guarantees in Oracle Blockchain Table Implementations

Abstract

Oracle Blockchain Tables introduce a cryptographically verifiable append-only ledger model within
the Oracle Database environment, providing tamper-evident transactional integrity while maintaining
full SQL operability. This article evaluates the behavior of Blockchain Tables under controlled
workloads, concurrent insertion patterns, rollback conditions, failure simulations, and full-stack
application workflows. Results show that Blockchain Tables reliably prevent unauthorized
modifications and ensure historical traceability through hash-chain linkage. However, concurrency
performance is influenced by commit ordering, and correction workflows require compensating
transactions to maintain interpretability. When integrated into application frameworks such as Oracle
APEX, transactional robustness depends on careful alignment of session state and commit boundaries.
The study concludes that Blockchain Tables offer strong integrity guarantees well-suited for audit
sensitive domains, provided that system design accounts for the operational implications of
immutability.
