Great report from Multichain audit partner @Verichains
It makes MPC + TSS more secure, all funds are SAFE.

[Multichain (Previously Anyswap) @MultichainOrg]

Wow 👀👀👀
#zkRouter testnet coming soon!

POC - the first cross-chain txn (Eth2 ->Fantom) using #zkRouter succeeded a few minutes ago👉 https://t.co/eBG44QTnPL

Huge progress achieved!🚀🚀
Stay tuned👀👀

[Multichain (Previously Anyswap) @MultichainOrg]

👋#zkRouter Launched
It's a new start!
Here we are inviting two ZKP masters to share some insights!
@XChang_SH - #zkRouter Lead at Multichain
@ChaoticBeautys - ZKP Research & Development at @BNBCHAIN

💕Shout-out to @myhopefulfuture for being host

What is MPC? by @multichaindao https://t.co/QyKDk26sxD

[Zhaojun @zhaojun_sh]

Multichain fastMPC support SR25519 signature which used by #Polkadot

Keep building.🐾

2) In its distributed implementation, the private key is divided into N copies, and then each of the N individuals in the group holds one copy. The public key is calculated through the distributed algorithm.

[三四南北 @HaijunCai]

1) In the digital signature algorithm, a private key is generated and then the corresponding public key is obtained. In this process, it is a centralized algorithm for a single private key.

[三四南北 @HaijunCai]

Distributed key technology is a comprehensive cryptography project, which is mainly based on secure multiparty computing (SMPC), including the distributed implementation of digital signature and asymmetric encryption and decryption technology.

[三四南北 @HaijunCai]

Compared with multisig solution, the transactions generated by FastMPC protect the privacy of signers by not disclosing T + 1 participants participating in the signature.

[三四南北 @HaijunCai]

FastMPC algorithm adopts ECDSA / EDDSA threshold signature, zero knowledge proof, Paillier homomorphic encryption and decryption, non extensible trap commitment protocol, verifiable secret sharing protocol, share transformation protocol and other technologies.

[三四南北 @HaijunCai]

The architecture between FastMPC and external applications (bridge / router) is shown below:

[三四南北 @HaijunCai]

FastMPC includes three main functions:
1.Key generation is used to create secret sharing ("keygen") without trusted dealers.
2.Use secret sharing, Paillier encryption and decryption to generate a signature ("signing").
3.Preprocessing data before generating signature.(“pre-sign”)
