1. In order to broadcast your transaction, you must be running the Petrachor node, and it must be synced with the network. If your Petrachor node is not running, or you have not turned on the json RPC, then you cannot broadcast a transaction. Make sure your json RPC port is listening on the default port 8545 ./petrachor -j -v 8

2. Once your node is running and has imported all blocks, you can now broadcast a transaction. Make sure you do not close the terminal window that is running the Petrachor node, or else it will kill the program. One option for doing this is running the application "screen" (you can find instructions here). Another option is to open a second terminal window, so that you have the Petrachor node in one terminal and the command line in the second terminal. I would suggest using two terminal windows because if you are not mining, you will need to enter the master passphrase for your wallet, and your key passphrase if you created one, after you enter the sendTransaction command.

3. Make sure all values are in hexadecimal format. Your "value" must be converted to hexadecimal, so for sending 100 PTA you will use 0x56BC75E2D63100000

Your command should look like this:

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendTransaction","params":[{"from": "0xf1714d1d16087b379a317b32019236337fa18661", "to": "0x7a9ee17c2221296adad0b4a1337d0d18b935f46c", "value": "0x56BC75E2D63100000"}],"id":1}' 127.0.0.1:8545

We agree with you. Merchant adoption and payroll services are key to the integration of a currency, eliminating the need for an exchange.

We plan to use a series of proof of concepts, to demonstrate the benefits of Petra, utility tokens, and low transaction fees.

These free apps will help demonstrate many benefits of using Petra over fiat, while also providing an immediate benefit to those using the app.

By releasing proof of concepts, we hope to show off the advanced functionality and usability of Petrachor, and work with other app developers to help integrate the same payment system.

Please be advised that an exchange listing has been announced for Petrachor.

Petrachor has been developed over the past 2 years, and the mainnet was launched on March 13. Everything in the description has been implemented.

Petrachor does use a Proof-of-Stake consensus, the Ariel Protocol. This works differently from other Proof-of-Stake smart contract platforms like EOS or TRON, because it does not use delegates. Every Petrachor node is an equal peer, and eligible to earn block rewards for contributing to the security of the network.

Bitcoin's Proof-of-Work consensus is similar to the Ariel Protocol. With Bitcoin, your hashrate determines your probability of finding a block, while with Petrachor your wallet balance determines this probability. The main innovation here is that computers are bad at creating randomness, but by using BLS cryptography, we are able to provide a secure truly random beacon to mimic the hashrate war that Proof-of-Work is famous for, but in an energy-efficient manner.


Petrachor and Ethereum have identical address lengths and both are hexadecimal, but otherwise they are completely different. Ethereum uses ECDSA cryptography to generate a public and private key, while Petrachor uses BLS cryptography. The two are not compatible, so if you generate an Ethereum address, and send Petra to that address on the Petrachor blockchain, those coins are gone forever.

Why did we replace the signature scheme with BLS?
Many reasons, but I won't go into all of them. One cool thing about BLS signatures is that you can aggregate an unlimited number of them into one single signature. This will allow us to compact the chain data, saving space, and opening up new possibilities for light-clients running on mobile and other storage restricted devices.


You can probably see by now that our main focus is minimizing hardware requirements, bandwidth, and energy, which enables more people to maintain a copy of the blockchain, and ultimately maximizes censorship resistance. With this in mind, we have also changed the target block time from 13 seconds (ETH) to 30 minutes. That may seem like a long time, but again this choice is to reduce storage requirements, in particular block headers, which over many years can cause a large amount of blockchain bloat. But don't fear, we will be adding a payment layer for instant and confidential transactions, so you can use Petrachor with the same speed, reliability, and privacy as cash.

Petrachor also has designs to replace the Ethereum Virtual Machine with a new smart contract platform that will simplify and improve our ability to run decentralized applications. We will let you know when the new upgrade has been deployed.

If you run into any problems compiling the source code and connecting to the Petrachor network, please reach out to us on our Telegram Group. We will be happy to answer any questions you may have.

Petrachor will not have masternodes.

The Petrachor team is working on layer 2 solutions that enable instant, low-fee transactions.

The Petrachor Telegram group is now open for general discussion:

https://t.me/petrachor

Right now we have a small team of developers working full-time.

We are currently focused on designing and implementing upgrades to the core chain, so that we can more easily extend functionality and usability in the future.

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.

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

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.

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.

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 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.
