Our ultimate goal with Reeve is to create a financial landscape that is completely transparent for all. To accomplish this, we log financial records directly onto the Cardano blockchain in the form of signed and permanent entries. The moment this information is secured on Cardano, it becomes impossible for anyone to alter it. Consequently, you can trust that each individual record is thoroughly tamper-proof and always available for independent verification.
