Capability-based security — enabling secure access control in the decentralized cloudWhen the tech industry began the transition to cloud-based resource provisioning, the attack/security vectors in which DevOps and CISOs focus to protect their resources, shifted along with it. Suddenly, protecting users’ data required a fundamentally new approach to containing resources. Rather than simply ‘defending the perimeter’ (through ownership of network infrastructure, firewalls, NICs etc.) the model ...

**Mineable Oracle Contract **(MOC) is an oracle schema that implements a mineable proof of work (POW) competiton. Once aggregated, validated, and processed into a consumable output — these oracle data entries will be internally referred to as ‘truthpoints’. This project draws high-level inspiration from the EIP918 Mineable Token as an abstract standard that uses a challenge-driven keccak256 Proof of Work algorithm for token minting and distribution. MOC leverages a proven game-theoretical com...

Bitcoin is a better solution for decentralized finance than most think. With the highest and most distributed proof-of-work base, Bitcoin is a natural fit for decentralized financial applications where security through immutability (or determinism) is imperative. **Mining hashrate **is a key security metric. The more hashing (computing) power in the network, the greater its security and its overall resistance to attack. Although Bitcoin’s exact hashing power is unknown, it is possible to esti...

We will leverage PowerBi to allow you to visualize the contract attributes, transactional data, etc. within the context of Azure Blockchain Workbench. We will finish the walkthrough by hosting this dashboard in a Microsoft Teams channel for easy a...
