> What exact counter party risk is eliminated by blockchain technology?
Some specific examples currently available:
• Atomic swaps, where traded assets are immediately moved between accounts upon execution of the trade, eliminate the possibility that settlement will not complete.
• Real-time commerce, where merchants accept payments in a format that can immediately be turned around and spent, without waiting for reimbursement from third-party networks.
• Loans backed by on-chain collateral, such that default triggers immediate transfer of collateral, eliminates the risk that collateral may not be obtainable upon default, or that the value of collateral may fall too far before the loan is liquidated.

Open databases can be digested and analyzed by open-source tools, and by trusted independent third-parties. Closed databases cannot be analyzed by anyone except for the database owner and government authorities. Some government authorities are trustworthy, others are under-resourced, incompetent or corrupt. Even if you personally won't read the full history, you benefit from other people being able to do so.

Problems can have multiple good solutions! Still, open API access is different from open access to underlying data and algorithms. Open APIs and blockchains can co-exist and benefit from each other.
> What about fraud?
Fraud is a complex topic. The traditional financial system has seen lots of fraud over the years (think about what we witnessed in 2008). Credit card fraud is also a rampant problem that is only managed by large financial firms heavily surveilling payment networks.
There are fraud vectors that blockchain networks are more susceptible to—just like there are other fraud vectors that blockchain networks are less susceptible to than traditional financial systems.
In my view, the greatest fraud risk in crypto comes from the issuance of tokens that are questionable in some way—a risk that I think can be eliminated if strong controls are implemented regarding the issuance of tokens on-chain.
