Javascript library for BLS (Boneh-Lynn-Shacham) signatures and signature aggregation, tailored for use in Eth2.
@ -19,10 +19,10 @@ To use native bindings you must install peer dependency `@chainsafe/blst`
yarn add @chainsafe/bls @chainsafe/blst
```
You must initialize the library once in your application before using it. The result is cached and use across all your imports
By default, native bindings will be used if in NodeJS and they are installed. A WASM implementation ("herumi") is used as a fallback in case any error occurs.
```ts
import {init, SecretKey, secretKeyToPublicKey, sign, verify} from "@chainsafe/bls";
import {SecretKey, secretKeyToPublicKey, sign, verify} from "@chainsafe/bls";
(async () => {
await init("herumi");
@ -45,48 +45,52 @@ import {init, SecretKey, secretKeyToPublicKey, sign, verify} from "@chainsafe/bl
### Browser
If you are in the browser, import from `/browser` to import directly the WASM version
If you are in the browser, import from `/herumi` to explicitly import the WASM version
```ts
import bls from "@chainsafe/bls/browser";
import bls from "@chainsafe/bls/herumi";
```
### Native bindings only
If you are in NodeJS, import from `/node` to skip browser specific code. Also install peer dependency `@chainsafe/blst` which has the native bindings
If you are in NodeJS, import from `/blst-native` to explicitly import the native bindings. Also install peer dependency `@chainsafe/blst` which has the native bindings
```bash
yarn add @chainsafe/bls @chainsafe/blst
```
```ts
import bls from "@chainsafe/bls/node";
import bls from "@chainsafe/bls/blst-native";
```
### Native bindings + WASM fallback
### Get implementation at runtime
If you want to offer a fallback in NodeJS, first try to load native bindings and then fallback to WASM. Also install peer dependency `@chainsafe/blst` which has the native bindings
```bash
yarn add @chainsafe/bls @chainsafe/blst
```
If you need to get a bls implementation at runtime, import from `/getImplementation`.
```ts
import {init} from "@chainsafe/bls";
import {getImplementation} from "@chainsafe/bls/getImplementation";
try {
await init("blst-native");
} catch (e) {
const bls = await getImplementation("herumi");
```
### Switchable singleton
If you need a singleton that is switchable at runtime (the default behavior in <=v6), import from `/switchable`.
```ts
import bls, {init} from "@chainsafe/bls/switchable";
// here `bls` is uninitialized
await init("herumi");
console.warn("Using WASM");
}
// here `bls` is initialized
// now other modules can `import bls from "@chainsafe/bls/switchable"` and it will be initialized
```
The API is identical for all implementations.
## Benchmarks
- `blst`: [src/blst](src/blst) (node.js-only, bindings to C via node-gyp)
- `blst`: [src/blst-native](src/blst-native) (node.js-only, bindings to C via node-gyp)
- `herumi`: [src/herumi](src/herumi) (node.js & browser, wasm)
- `noble`: [noble-bls12-381](https://github.com/paulmillr/noble-bls12-381) (node.js & browser, pure JS)
