Mainnet Launched






Petrachor is a comprehensive monetary system and blockchain application platform, empowering a decentralized Internet experience.

Our light-weight architecture blockchain can run from a phone, tablet, or desktop - never trust a third-party again.

Petrachor uses 100% original code for the Ariel Protocol - a resource efficient and censorship resistant Proof of Stake consensus.

All Petrachor wallets can mine - earn rewards, reduce inflation, and strengthen security.


Overview

Petrachor uses the Ariel PoS protocol, which is our custom implementation of the original iChing Proof-of-Stake consensus, a secure and eco-friendly Satoshi-style protocol. iChing is a natural mimic of Bitcoin consensus; as a result, scalability solutions for Bitcoin can be immediately used in Petrachor. By applying this blockchain protocol to a fork of the Ethereum source code, we deliver a powerful new dApp platform combining the energy-efficiency of PoS with the power and versatility of Ethereum.



Proof of Stake

Keeping in the spirit of naming consensi after ghosts, Ariel incarnates an academic protocol that was proven to satisfy important formal chain properties including common prefix, chain quality, chain growth, and chain soundness.


BLS Signature Scheme

The Boneh-Lynn-Shacham unique signature scheme is used for the core random beacon of Ariel. By also securing accounts with BLS, we pave the road towards interesting future extensions, such as multisignatures, threshold signatures and aggregate signatures.


BLS12-381 Elliptic Curve

The elliptic curve used by our signature scheme is BLS12-381, a Barreto-Lynn-Scott curve. This curve was introduced in Sapling, the latest upgrade to the ZCash protocol, with the aim to improve efficiency and security while reducing memory intensivity.

Petrachor Mainnet was launched on March 13, 2019. A total of 1 billion Petra (PTA) were created in the genesis block. 0.2% of remaining Petra are auction daily. To participate in the auction, visit https://petrachor.com

The token you're referring to is a smart contract, deployed on the Ethereum blockchain.

Petrachor is a Proof of Stake blockchain, not a smart contract. You can deploy your smart contract on Petrachor, or any other EVM compatible chain.

Is this built on Ethereum or does it have it's own mainnet?

Petrachor has its own mainnet. It is not built on Ethereum.

Petrachor uses a new Proof of Stake consensus, instead of Proof of Work, so you don't need to consume large amounts of electricity to earn block rewards.

Petrachor is fully compatible with Ethereum Virtual Machine smart contracts, and dApps.

Thanks! We are glad to hear you like the project.

100% of the initial supply is distributed in the public auction. No presale, no private sale, and also no marketing, like Bitcoin.

The auction distributes 0.2% of the remaining Petra per day, so about 90% remain to be distributed, and about 50% will be distributed after the first year. Plenty of time left to grab some coins from the genesis balance.

In order to participate in the auction, you will need to generate a Petrachor address, which is different from an Ethereum address (BLS instead of ECDSA).

Petrachor is not yet listed on any exchange (to our knowledge).

Currently, the easiest way to get Petra, and start using the Petrachor blockchain is by participating in the daily auction.

Compiling the source code and running a node is easy. This ensures authenticity of the code, and allows you to generate a Petrachor address, which you can then use to get Petra from the daily auction.

We are developing a GUI wallet to simplify the process of installing the Petrachor wallet, and interacting with the blockchain. In the mean time, please feel free to respond to my PM, and we will do our best to get up and running with the CLI client.

Ok. Thanks for fast response. Will stick to auction for now. Please update when exchange listing happens.

Petrachor has been designed to enable every user to run a full node, verify transactions, and remove dependence on third-parties.

It looks like you have successfully created a Petrachor address.

When using your address to send or receive funds, you will want to include the prefix "0x" to indicate that it is hexadecimal.

In your case you will use: 0xf18297504f21b91d7c3d160d66d7c43e9cc5cbef

You can now use your Petrachor address to participate in the auction or receive Petra from another account. Once you have Petra, you can begin interacting with the Petrachor blockchain.
