Metadium Testnet
will build logrot (log rotator) and metadium.tar.gz in build directory, in addtion. Vitalizing the concept of self-sovereign identity enables individuals to exercise total control of their own identity - managing, securing, and utilizing personal data only under the owner’s consent. Keepin will continue to be updated to offer better experience for users in managing data and authentication. Metadium will connect to various services and application to vitalize and enlarge Meta ID network. Updated version of Keepin will support users to create and manage Meta ID, decentralized identifier (DID) of Metadium blockchain.
Set up the data directory and copy the genesis file as follows. If this shows nodes as configured in config.json, it's time to initialize etcd. Metadium is an identity project based on the Self-Sovereign Identity (SSI) model.
To aid this, Geth has built-in support for a JSON-RPC based APIs (standard APIs andGeth specific APIs). These can be exposed via HTTP, WebSockets and IPC (unix sockets on unix based platforms, and named pipes on Windows). This will start geth in fast-sync mode with a DB memory allowance of 1GB just as the above command does.
Build with LevelDB instead of Rocksdb
You can further tune the mining by changing the default gas limit blocks converge to (--targetgaslimit) and the price transactions are accepted at (--gasprice). The IPC interface is enabled by default and exposes all the APIs supported by Geth, whereas the HTTP and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons. These can be turned on/off and configured as you'd expect.
Account files are in keystore directory, and geth/nodekey is the node key / id file. Or one can use gmet to create accounts and node keys, and copy them to data directory. Once initial members / accounts and nodes are determined (at least one member / account and node are required), create a configuration file using conf/config.json.example as a template, say config.json.
Metadium Basics
The go-ethereum library (i.e. all code outside of the cmd directory) is licensed under theGNU Lesser General Public License v3.0, also included in our repository in the COPYING.LESSER file. Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you almost certainly would like to do that without any real money involved until you get the hang of the entire system.
- Instead of connecting the main Ethereum network, the client will connect to the test network, which uses different P2P bootnodes, different network IDs and genesis states.
- Updated version of Keepin will support users to create and manage Meta ID, decentralized identifier (DID) of Metadium blockchain.
- Only that account can create the governance contracts, and only that node is allowed to generate blocks before governance contracts are established.
- Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you almost certainly would like to do that without any real money involved until you get the hang of the entire system.
- As a developer, sooner rather than later you'll want to start interacting with Geth and the Ethereum network via your own programs and not manually through the console.
Building
In other words, instead of attaching to the main network, you want to join the testnetwork with your node, which is fully equivalent to the main network, but with play-Ether only. Start up Geth's built-in interactive JavaScript console, (via the trailing console subcommand) through which you can invoke all official web3 methodsas well as Geth's own management APIs.
By using DLT it enables individuals to retain sole ownership over their online and offline identities, and control just how their personal data is shared and distributed.
A member designated as bootnode has a special meaning. Only that account can create the governance contracts, and only that node is allowed to generate blocks before governance contracts are established. These are recorded in the genesis block as the coinbase and the last 64 bytes of the extraData. One can use the following command lines to join the Metadium networks. Note that the default RPC port for gmet is 8588, and p2p port is 8589.
It will also create a persistent volume in your home directory for saving your blockchain as well as map the default ports. There is also an alpine tag available for a slim version of the image. Instead of connecting the main Ethereum network, the client will connect to the test network, which uses different P2P bootnodes, different network IDs and genesis states. If you are to use existing or pre-created node key, copy the file to geth directory. First create data directory in /opt/, say /opt/meta.
With registered Meta ID, users will be able to sign-in to multiple services in highly secure and convenient way. In addition, Keepin enables users to securely store everyday data and easily manage META via wallet. The forthcoming everyday life Metadium aims to present is the absolute liberty and optimal convenience in the use of identity in everyday life. The go-ethereum binaries (i.e. all code inside of the cmd directory) is licensed under theGNU General Public License v3.0, also included in our repository in the COPYING file.
Upcoming Events
This tool is optional and if you leave it out you can always attach to an already running Geth instance with geth attach. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Metadium is an ecosystem built on a public identity blockchain. Metadium’s vision is to create a free world through self-sovereign identity. Which will start mining blocks and transactions on a single CPU thread, crediting all proceedings to the account specified by --etherbase.
As with geth, if --datadir is missing, ~/.metadium is the data directory. As a developer, sooner rather than later you'll want to start interacting with Geth and the Ethereum network via your own programs and not manually through the console.
