Problems solved by technology

[0002] Some early attempts have been made to enable the procurement of goods and services through blockchain-based smart contracts secured by trusted or neutral third parties, but these have been limited to individuals or companies that may be colluding with one party in the transaction groups, or programs that are equally subject to subversion or manipulation of insufficient information to make credible judgments
[0003] Existing reputation systems fail to track individuals across multiple providers of goods and services, making it possible for individuals to provide inauthentic positive or negative feedback that affects provider reputation without affecting their own

example 1

[0075] Party 1 (302) is an anonymous individual, such as a user. The participant 1 ( 302 ) has a reputation amount 1232 . Party 1 (302) wishes to rent movie M for 24 hours to play on an authenticated multimedia content player using a nearby cached copy.

[0076] Participant 2 (304) is an anonymous content delivery network (CDN) service. The participant 2 (304) has a reputation of 140,000. Party 2 (304) has a cached copy of movie M located close to Party 1 (302).

[0077] Party 3 ( 306 ) is the named content owner 306 . The reputation of the party 3 (306) is greater than 1 million. Party 3 (306) owns the content and provides rental services, but requires a guarantor of over 100,000 reputation backed by escrow of over 100,000 bitcoins or other cryptocurrency (BTC).

[0078]Participant 4 (308) is referred to as the transaction guarantor. The reputation of the party 4 (308) is >200,000. Participant 4 (308) uses 2000 BTC in custody as a "partial reservation" guarantee to pre...

Crowdfunding funds will accumulate multi-party intelligence. Contracts are formulated as verifiable open-source zero-knowledge schemes or traditional cryptocurrency-based smart contracts. It pays money based on knowledge in the reputation knowledge space, and possibly based on fulfillment of the goals of the prediction market associated with the reputation.
