UltraSONIC is a state machine with capability-based memory access. In simple words, this means
state machine with cryptographically-protected memory cells
.
What is capability-based memory access (or capability-addressable memory, CAM)? The computers we all used to are random memory access machines (RAM), where a software accesses freely-addressable global memory. This had opened a door for the all the vulnerabilities and hacks happening in computer systems across the world for the past decades... CAM model instead, divides all memory into parts (called words) addressable only with some access token (called capability). You may think of this as of a memory where each part is "owned" by certain party, and can be accessed or modified only given a proof of ownership.
UltraSONIC leverages zk-AluVM, so it is (1) zk-STARK-compatible and (2) exception-less, made with category theory in mind.
SONARE is a part of a larger ecosystem used to build safe distributed software, which includes:
- Strict types: strong type system made with generalized algebraic data types (GADT) and dependent types;
- AluVM: a functional register-based virtual machine with a reduced instruction set (RISC); UltraSONIC uses a zk-STARK-compatible subset of its instruction set architecture (called zk-AluVM);
- [SONIC]: toolchain for building SONIC contracts;
- SONARE: runtime environment for running SONIC contracts;
- Cation: a general-purpose high-level programming language made with category theory, which features strict types, termination analysis and can be formally verified;
- Contractum: a domain-specific version of Cation for writing programs for UltraSONIC.
