This presentation proves a general introduction to the API Economy, to the Blockchain network Alastria, and to the open source WSO2 API Manager. It also includes a demo on how to use API Manager for API consumption management and its integration with a Smart Contract deployed in blockchain for the automatic pricing of this consumption.

[WSO2Con EU 2018] Blockchain in the Business API Ecosystem - API Consumption Pricing Using Smart Contracts
- 1. IT R&D & Innovation / Blockchain Manager Blockchain in the Business API Ecosystem: API Consumption Pricing Using Smart Contracts Sergio G. Miranda
- 3. PHASES OF BLOCKCHAIN ADOPTION Identify the potential of blockchain Identify opportunities Testing and tech evangelism Production-ready Be aware of implications Not everything is cryptocurrency Implies collaboration based on transparency – decentralization of data Internal promotion of PoCs Identify processes, activities, producst that can be optimized with blockchain Blockchain technology is adopted Source: https://www.atsistemas.com/es/blog/
- 4. BLOCKCHAIN? WHY? NETWORK GOVERNANCE INTEGRATION WITH LEGACY SYSTEMS SCALABILITY INTEROPERABILITY DATA PRIVACY AND SECURITY TRACEABILITY COMPLIANCE WITH LEGAL AND REGULATORY ISSUES 1 High level of trust and risk reduction 2 - Reduced – operating costs 3 Potential to identify inefficient processes
- 11. API Economy
- 12. Term related to the use of “business APIs” to positively affect the company. Frequently related to monetary benefits. Main business drivers: ○ Accelerate time to market ○ Reaching new markets/customers ○ Innovation (at a low cost/risk) ○ Improved sharing of assets across the enterprise (domains) are all very valuable scenarios for the use of APIs ○ APIs + Cloud = Scalability without limits API Economy
- 13. API Business Models Partner-Only API Model “Closed Model”, where only partners of the API’s owner can access and consume the AP “Public” Model where anyone in the general public can access and consume the API, usually for a fixed number of transactions Internal APIs Model which are maintained privately within an organization and aimed at accelerating and integrating internal units and processes
- 14. 5 Steps to Monetize Your APIs 1. Establish your business case and roadmap 2. Ensure you have the right funding and organizational model 3. Treat APIs as products with an Agile API product lifecycle and governance 4. Ensure you have the right technology platform to build and manage your APIs 5. Measure and monitor API KPIs (run-time performance, financials and developer feedback)
- 15. Use cases 1/2 Stubhub Sales of tickets for events (stubhub.es / developer.stubhub.com) Success case with WSO2: https://wso2.com/casestudies/how-apis-are-driving-stubhubs-business/
- 16. Use cases 2/2 APIs Mashup When different APIs from different suppliers are completely necessary to provide a common service. e.g.: Mobile payment App for booking parking lots (cameras, IoT, geopositioning, commercial agreements ...)
- 17. Summary - API Economy 7 For example, with the use of an API Manager, that allows the management and publication of data for its use by third parties. We have more and more data obtained by the interaction of our users with our website, mobile applications, sensors and connected devices. It is possible to monetize the value from this data and its processing. But for this it is necessary to integrate in a satisfactory way the mechanisms of interaction with this data. Allowing control of the use for adequate pricing and monetization.
- 18. Business API – Motivation and requirements 8 Use of the Blockchain technology as a trusted mechanism for the transparent charging of data consumption. Trust must be established between the provider and the consumer of the data It’s required the use of an API Manager and Smart Contracts deployed on a blockchain
- 20. Implementation strategy of API Economy Definition of Throttling Policies (Client, App ...) Service Levels (Requests / sq) API Analytics Information (Authentication, Backend ...) Management of Subscriptions and Billing Plans. Definition of data structures (Data Management) Documentation based on Swagger, RAML To provide EndPoints for Integrators (Prototypes). Security Policies (OAuth2, JWT ...)Creation of Backend Services Tokens Emission Versions Management APIs Planning & Design Integration and Management of Consumption Publication and Consumption Exploitation and Monitoring of APIs
- 21. API Governance 1/2 Monitoring Resources and APIs definition Standardization for APIs development API documentation Testing
- 22. API Governance 2/2 Security policies Monetization CI and CD strategies Version policies
- 23. Market solutions
- 24. Technology stack
- 25. WSO2 API Manager 5 It facilitates the development of APIs by abstracting the security layer. It can be integrated into the CI/CD Company and being deployed in Cloud, On Premise or Hybrid infrastructure 100% Open Source under Apache 2.0 license It ensures the availability of backends and facilitates the APIs publication and their consumption by development teams. The WSO2 suite provides a complete management of the available APIs (resources) for customer and supplier systems as well as internal systems of the company. It allows analysis and monitoring of theresources and design of dashboards and gadgets
- 26. WSO2 API Manager - Components 6 Data Analytics: Statistics for published and consumed resources Key Manager: Security layer for accessing resources with OAuth 2.0. Portal Publisher: Website for publishing APIs - Swagger or WSDL contracts -. API Gateway: Management of requests between clients and backends. Portal Store: It offers a resources catalog and facilitate the consumption / testing of the APIs. Traffic Manager: Rules definition to manage traffic between customers and backends using throttling rules.
- 27. Blockchain solution 7 Not depending on the infrastructure Smart Contracts • Development in Solidity • OpenZeppelin patterns API Rest Integration DApps Frontend -> Events Explorer Explorer of Smart Contract Transactions and events Using API JSON-RPC with web3js to connect to the working node Direct filter to the blockchain network (there’s no processing in frontend nor backend) Interaction with Smart Contracts using java (web3j), js(web3js) and golang Decoupled Architectures Blockchain network • Nodes • Consensus
- 28. Blockchain trilemma RELEVANT CONSIDERATIONS Scalability/Speed Security Decentralization Distribution of nodes; participant involvement Ability to handle a number of transactions by a number of users on the network Immutability of the ledger; resistance to attacks such as 51% attacks
- 29. Blockchain network 9 Based on IBFT algorithm, instead of “Proof of work”->better features (approx 1000 tx/s), without “forks” in the chain It adds constellation to geth, a way to store and run private Smart contracts Designed to build permissioned networks, where all the participants are well known and have a solid reputation A “lightweight” get fork -> fully compatible with EthereumBased on QUORUM Alastria
- 30. Permissioned blockchain network. ALASTRIA Ease of collaboration and integration of participants RELEVANT CONSIDERATIONS Other participants Multi-industry national blockchain network… … to support transactions with full legal validity… Physical location of ALASTRIA nodes
- 31. Permissioned blockchain network. ALASTRIA Ease of collaboration and integration of participants RELEVANT CONSIDERATIONS Other participants Private transaction among participants Multi-industry national blockchain network… … with appropriate levels of privacy: … to support transactions with full legal validity…
