# Quickstart Planetmint is a metadata blockchain. This introduction gives an overview about how to attest data to Planetmint. First, simple transaction creation and sending is shown. Thereafter, an introdcution about how to set up a single node or a cluster is given. ## The IPDB Testnet - sending transactions The IPDB foundation hosts a testnet server that is reset every night at 4am UTC. The following sequence shows a simple asset notarization / attestion on that testnet: Create a file named notarize.py ``` from planetmint_driver import Planetmint from planetmint_driver.crypto import generate_keypair plntmnt = Planetmint('https://test.ipdb.io') alice = generate_keypair() tx = plntmnt.transactions.prepare( operation='CREATE', signers=alice.public_key, asset={'data': {'message': 'Blockchain all the things!'}}) signed_tx = plntmnt.transactions.fulfill( tx, private_keys=alice.private_key) plntmnt.transactions.send_commit(signed_tx) ``` install dependencies and execute it ``` $ pip install planetmint-driver $ python notarize.py ``` # Install Planetmint ## Local Node Planemtint is a Tendermint applicatoin with an attached database. A basic installation installs the database, Tendermint and therafter Planetmint. Planetmint currently supports Tarantool and MongoDB database. The installation is as follows: ``` # Tarantool $ curl -L https://tarantool.io/release/2/installer.sh | bash $ sudo apt-get -y install tarantool ``` *Caveat:* Tarantool versions before [2.4.2](https://www.tarantool.io/en/doc/latest/release/2.4.2/) automatically enable and start a demonstration instance that listens on port `3301` by default. Refer to the [Tarantool documentation](https://www.tarantool.io/en/doc/latest/getting_started/getting_started_db/#creating-db-locally) for more information. ``` # MongoDB $ sudo apt install mongodb ``` Tendermint can be installed and started as follows ``` $ wget https://github.com/tendermint/tendermint/releases/download/v0.34.15/tendermint_0.34.15_linux_amd64.tar.gz $ tar zxf tendermint_0.34.15_linux_amd64.tar.gz $ ./tendermint init $ ./tendermint node --proxy_app=tcp://localhost:26658 ``` Planetmint installs and starts as described below ``` $ pip install planetmint $ planetmint configure $ planetmint start ``` ## Cluster of nodes Setting up a cluster of nodes comes down to set up a cluster of tendermint nodes as documented at [Tendermint](https://docs.tendermint.com/v0.35/introduction/quick-start.html#cluster-of-nodes). In addition to that, the database and Planetmint need to be installed on the servers as described above. ## Setup Instructions for Various Cases - Quickstart link below - [Set up a local Planetmint node for development, experimenting and testing](../node-setup/index) - [Set up and run a Planetmint network](../network-setup/index) ## Develop an App Test To develop an app that talks to a Planetmint network, you'll want a test network to test it against. You have a few options: 1. The IPDB Test Network (or "Testnet") is a free-to-use, publicly-available test network that you can test against. It is available at [IPDB testnet](https://test.ipdb.io/). 1. You could also run a Planetmint node on you local machine. One way is to use this node setup guide with a one-node "network" by using the all-in-one docker solution, or manual installation and configuration of the components. Another way is to use one of the deployment methods listed in the [network setup guide](../network-setup/index) or in the [the docs about contributing to Planetmint](../contributing/index).
