Paying attention I learned that Jorge Lopez CTO at Gravity is building on Dr. SES Smart Contracts
Gravity is a resilient distributed application runtime that empowers/induces safe computational semantics, cryptographically secure protocols and orthogonally persistent state. The Gravity protocol is a language based on lambda calculus, prototypes, object capabilities and message passing to create distributed applications. Gravity nodes are isolated runtime processes connected through cryptographic capabilities. They jointly create a distributed runtime and implement the following protocols:
- A distributed ordered message queue to share an event loop and timeline. - A distributed relative address space / scope, to refer to and access objects in the network securely. - A distributed development environment, to collaboratively create, debug and share objects.
Gravity Applications are executed on top of this runtime, and selectively share protocols, state and computation. Gravity applications are: # Persistent: The state of the node and its data structures are durable. The state of the node can be recovered after failure, reboot of the Gravity node or moving across nodes. # Private: Gravity nodes can create an isolated shared state and event timeline. # Verifiable: The integrity of the state, protocol, and execution of a Gravity node is verifiable. # Transactional: State transitions are isolated and atomically consistent across Gravity nodes. # Distributed: Application state is selectively stored across multiple nodes and doesn’t rely on single global mutable state. Applications are networked and only optionally share state, making them inherently scalable. # Secure: A Gravity node can keep secrets. All state is stored and transmitted in an encrypted form. # Safe: Gravity applications follow a secure computation model based on object capabilities and the principle of least authority. # Redundant: Gravity applications may use multiple nodes to execute/verify code, to send messages through, or to store state. Gravity provides constructs that enable high availability and fault recovery. # Portable: Gravity applications and data structures may move across gravity nodes, further improving resilience and adaptability. # Reflective: Protocols, state, and computation may be defined, accessed, analyzed and updated from within Gravity itself.
