This document discusses several real-world applications of blockchain technology beyond cryptocurrencies like Bitcoin. These include using blockchain for bank guarantees, food supply chains, shipping insurance, charity distributions, voting, decentralized justice, storage, content monetization, and providing anonymity and privacy. For each application, the document identifies key pain points in current solutions and how blockchain addresses these through responses like transparency, trust, speed, efficiency, security, and decentralization.
Blockchain: some examples
- 1. Blockchain Real examples of application beyond Bitcoin Gianluca De Maria Feb 2018
- 2. Fideiussione bancaria | Distributed Ledger Technology Speed ::: Scalability ::: Privacy ::: Security Responses: Tokenisation of Bank Guarantees Shared ledger viewable and maintainable by the Network A catalyst for simplification and standardization Painpoints Physical Document Management Track and reporting Lack of standardization
- 3. Food Supply Chain Blockchain Collaboration to Address Food Safety Worldwide Blockchain Food Safety Alliance in China Responses: Blockchain is naturally suited to traceback to the source of contamination Blockchain can provide trusted information on the origin and state of food Traceability prevent accountability to be diluted amongst different actors of the supply chain Safety & Quality :::Trust ::: Traceability ::: Transparency ::: Accountability Painpoints Food contamination Trust Lack of accountability
- 4. Shipping Insurance Maersk, EY, Microsoft, Willis Towers watson Blockchain to securely share shipping data Responses: From copies to distributed shared ledger Creation and maintenance of asset data from multiple parties Linkage of data to policy contracts Pricing or business process change based on information received Enable many different parties to settle upon the terms of premiums in a more timely fashion Transparency ::: Certainty ::: Efficiency ::: Better compliance ::: Secure audit trail Painpoints Multiple parties involved Complex paper chains Duplications, inefficiency, lack of data Changes needs to be declared Errors and fraud Tamper-resistance Insurance transactions are tedious and frictional Capital allocation
- 5. Charity WFP $1.4 million in food vouchers to 10,500 Syrian in 2017 Responses: No needs for third-party intermediaries Ledger records transactions in a secure manner that cannot be changed Speed-up transaction and reconciliation Biometrics for authentication Richer refugees profiles that collect data from different agencies Transparency ::: Speed ::: Efficiency ::: Security Painpoints Payment costs Vouchers handling Fraud
- 6. Voting Painpoints Slow Expensive 15$ Vs 0.5$ Ineffective No trust in the outcome Horizon State | MiVote.org.au Responses: constituencies can be engaged with immediacy design systems that directly engage and empower constituencies vote smartly and efficiently results can never be tampered with. System cannot be hacked, results can never be altered; voter identities are protected Blockchain is an immutable public ledger, trustless, and inspectable by all. Transparency ::: Integrity ::: Efficiency ::: Security ::: Privacy
- 7. Decentralized-justice Painpoints Slow Expensive Bribing No trust in the outcome Kleros P (VERDICT IS TRUE) = F (JURY, EVIDENCE, PROCEDURE) Responses: Transparency (evidence not tampered) Trust (selection of jurors not biased) Incentives (coins) to tell the truth Impartial and Incorruptible 1) Contract, 2) Securing Evidence, 3) Jury Selection, 4) Analysis, 5) Voting, 6) Appeal, 7) Token Redistribution Speed :::Transparency ::: Impartial ::: Incorruptible
- 8. Storage Painpoints Trust Cost Storj | Sia.Tech Responses: Encryption enables to verify the ownership of something digital, even if there are identical copies Encrypted Distributed Availability Trust ::: Efficiency ::: Security ::: Privacy
- 9. Content Monetization Painpoints Trust Barrier Mainstream: no real choice Ujo Music | Voise Trust ::: Efficiency ::: Security ::: Privacy Responses No needs for intermediaries Control over licensing User votes with tokens at stake
