The web application redirects to the web front-end of the identity provider via a sign-in button. 2 The user leaves the web application and is presented with the login screen of the identity provider. 3 The user id and password along with user claim and scope grants are sent to the identity provider’s backend server and validated. If validation succeeds, the user is redirected back to the web application along with either a token that will allow the web application to request an id and access token from the identity provider or it receives those tokens directly with the redirect. 4 Back in the web application, the user identity is now known via information encoded in the id token. Authorization for API calls is obtained by including the access token with every request to the web API. The web API will have to access the identity server at least once in order to validate the access token presented by the web client, but it will not have to do that for every request. Authorization happens in the web API, i.e. the web API decides what resources are available based on information contained in the access token. In addition to user id, the access token can contain user claims such as age, country of residence etc. https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1594684431337-5XYQH3WTJNDYGDH2EFPO/Key1.png Blog - Protecting APIs and Users with OAuth and Asymmetric Authentication https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1594684748738-GM87LJ5VPQFLOJ1MMGVP/Asymmetric+Flow.png Blog - Protecting APIs and Users with OAuth and Asymmetric Authentication - Asymmetric Authentication with Authorization Token 1 With asymmetric authentication, there is no need to redirect to a login screen because users are authenticated from the very first interaction with the web application. 2 Id and access tokens are requested automatically without user interaction from the identity server using a cryptographically signed message that proves the user’s identity. 3 User id and access token are obtained by the web application and used for claims-based authorization only (user claims are encoded in the tokens). When making an API request, a cryptographic signature is included along with the access token. The signature is unique for each request and therefore the web API is able to authenticate every request. Once authenticated, access to API resources is authorized based on the provided access token. https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1594685198587-OULJZI85RLQSZV7IXRHH/Key2.png Blog - Protecting APIs and Users with OAuth and Asymmetric Authentication https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1594685402915-8D134SH4I2I6PY42H0VX/Simplified+Asymmetric+Flow.png Blog - Protecting APIs and Users with OAuth and Asymmetric Authentication - Asymmetric Authentication without Authorization Token 1 If the web API does not depend on user claims included in the JWT access token then there is no need to obtain one from the identity server. The cryptographically signed request must include the public key in order for the web API to validate the signature. Therefore, the authenticated user's identity (public key) is provided to the web API with every request. In many scenarios this will be enough for managing authorization, for example if the user profile has to be loaded anyway in order to determine the user's registration status. https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1594685749277-YTFXBSDQKQ0NRDHXJXV3/API+Asymmetric+Flow.png Blog - Protecting APIs and Users with OAuth and Asymmetric Authentication https://proderivatives.com/blog/2019/7/13/guaranteed-income-for-crypto-miners monthly 0.5 2026-04-04 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1563051773877-I84AEY3PAGNXAUJQGNVD/Screen+Shot+2019-07-13+at+2.00.55+PM.png Blog - Guaranteed income for crypto miners https://proderivatives.com/blog/2019/6/28/fixed-value-payments monthly 0.5 2026-04-03 https://proderivatives.com/blog/2019/6/18/a-dumb-way-to-test-a-smart-contract monthly 0.5 2026-04-03 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1560875864066-DZSVXNFLTIJ2948A9YQB/Screen+Shot+2019-06-15+at+8.39.36+PM.png Blog - A dumb way to test a smart contract https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1560875982041-W7FB2YDVSUZADL5Z4QTX/Screen+Shot+2019-06-15+at+9.29.33+PM.png Blog - A dumb way to test a smart contract https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1560876087287-AZKVGQDG41SJ6LMMMT6K/Screen+Shot+2019-06-17+at+1.21.35+PM.png Blog - A dumb way to test a smart contract https://proderivatives.com/blog/2019/6/5/ww0w1rgtke9sogo79352d6l5vayg11 monthly 0.5 2026-04-03 https://proderivatives.com/blog/2019/6/5/time-and-volume-weighted-price-index monthly 0.5 2026-04-04 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1559771618739-WWTPMHW4XBIUGOQJHLA5/Screen+Shot+2019-06-05+at+2.53.00+PM.png Blog - Time and Volume Weighted Price Index https://proderivatives.com/blog/2019/5/10/minimizing-data-storage-cost-on-the-ethereum-network monthly 0.5 2026-04-04 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1557693375085-8YAIFV6ENEFIWE9QI107/Total+Gas+Usage.jpg Blog - Minimizing Data Storage Cost on the Ethereum Network https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1557693247081-PB4T7XHGFDYFXOMKIRCS/Average+Gas+Usage.jpg Blog - Minimizing Data Storage Cost on the Ethereum Network https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1607801420391-7UMS6A3Y7B582H3MAJCO/Chart.png Blog - Minimizing Data Storage Cost on the Ethereum Network https://proderivatives.com/blog/2019/5/8/blockchain-networks-as-technical-infrastructure monthly 0.5 2026-04-03 https://proderivatives.com/home daily 1.0 2026-04-05 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1557365382771-9SEF7KJQHXT0WT5KRM0W/ProDerivativesSplash.jpg ProDerivatives https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1557364384106-Z58YQPZ00JUA67O4DD7M/DSC04292.JPG https://proderivatives.com/prod daily 0.75 2026-04-03 https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1555364922625-T9QA7ZBREWOKXS0X1Z9X/Screen+Shot+2019-04-15+at+2.47.54+PM.png ProD Environment https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1555379061599-XSCMAPRH3HX0ENGFKLTN/Screen%2BShot%2B2019-04-15%2Bat%2B6.34.31%2BPM.jpg https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1555377156925-0OKIBKQHRCFYDP6TJX0V/Screen+Shot+2019-04-15+at+6.12.09+PM.png https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1555380173192-Z6SN1MT1GLX8V06N93CP/Screen+Shot+2019-04-15+at+7.02.20+PM.png https://images.squarespace-cdn.com/content/v1/5497b184e4b07cc94e3163a1/1555379061599-XSCMAPRH3HX0ENGFKLTN/Screen%2BShot%2B2019-04-15%2Bat%2B6.34.31%2BPM.jpg ProD Environment - Launch the application select network ETH in the main menu.
