A JS utility library (w/ typescript bindings!) to make calls to the Torus network
The Torus network assumes that n/4 of nodes may be malicious, and n/2 + 1 of the nodes are required for key reconstruction. Given these threshold assumptions, all API calls to the Torus nodes need to be checked for consistency while still allowing for early exits in optimistic scenarios where the first n/2 + 1 responses are from honest nodes.
Also, in order to prevent front-running by nodes, a commit-reveal process is also necessary for share retrieval.
This library handles these checks and allows you to query the Torus network easily through these APIs:
- retrieveShares
- getPublicAddress
- Typescript compatible. Includes Type definitions
- All API's return
Promises
This module is distributed in 4 formats
esmbuilddist/torusUtils.esm.jsin es6 formatcommonjsbuilddist/torusUtils.cjs.jsin es5 formatumdbuilddist/torusUtils.umd.min.jsin es5 format without polyfilling corejs minified
By default, the appropriate format is used for your specified usecase You can use a different format (if you know what you're doing eg. node) by referencing the correct file
The cjs build is not polyfilled with core-js. It is upto the user to polyfill based on the browserlist they target
CDN's serve the non-core-js polyfilled version by default. You can use a different
