# Unbiasable Randomness with VDF
The one you use for a billion dollars lottery. Not for some tiny dice games.
## Biasability of Distributed RNGs
# Stablecoin Protocol
After the CoLoa hardfork, 3 new consensus contracts are deployed:
* [**NewSD**](https://explorer.nexty.io/address/0x0000000000000000000000000000000000045678) - the stablecoin ERC20 token, initialized with zero supply.
* [**MNTY**](https://explorer.nexty.io/address/0x0000000000000000000000000000000000034567) - the ERC20 wrapper of a million of NTY. Anyone can deposit NTY to get the token, and withdraw back to NTY anytime. This token is convenient for dapp usage including the Seigniorage DEX. The DEX will only interact with MNTY, and never NTY.
# r<sup>2</sup>PoS - A Relay-friendly Proof of Stake
**r<sup>2</sup>PoS** is a **R**elay-friendly, unbiasedly **R**andomized **P**roof **o**f **S**take consensus, developed for the next upgrade of Nexty platform.
* Sealers can be registered by staking [NTF](https://explorer.nexty.io/address/0x2c783ad80ff980ec75468477e3dd9f86123ecbda) token and interact with the governance contract.
