As such, it provides features somewhat similar in scope to those found in Fabric. However, it is special-purposed for use in an identity system, whereas Fabric is general purpose. ## Technical Overview of Indy Please find the general overview of the system in [Overview of the system](docs/main.md). More documentation can be found in [docs](docs). ## Other Documentation - Details about the protocol, including a great tutorial, can be found on the [wiki](https://github.com/hyperledger/indy-plenum/wiki). - Please have a look at aggregated documentation at [indy-node-documentation](https://github.com/hyperledger/indy-node/blob/master/README.md) which describes workflows and setup scripts common for both projects. ## Indy Plenum Repository Structure - plenum: - the main codebase for plenum including Byzantine Fault Tolerant Protocol based on [RBFT](https://pakupaku.me/plaublin/rbft/5000a297.pdf) - common: - common and utility code - crypto: - basic crypto-related code (in particular, [indy-crypto](https://github.com/hyperledger/indy-crypto) wrappers) - ledger: - Provides a simple, python-based, immutable, ordered log of transactions backed by a merkle tree. - This is an efficient way to generate verifiable proofs of presence and data consistency. - The scope of concerns here is fairly narrow; it is not a full-blown distributed ledger technology like Fabric, but simply the persistence mechanism that Plenum needs. - state: - state storage using python 3 version of Ethereum's Patricia Trie - stp: - secure transport abstraction - it has [ZeroMQ](http://zeromq.org/) implementations - storage: - key-value storage abstractions - contains [leveldb](http://leveldb.org/) implementation as the main key-valued storage used in Plenum (for ledger, state, etc.) ## Dependencies - Plenum makes extensive use of coroutines and the async/await keywords in Python, and as such, requires Python version 3.5.0 or later. - Plenum also depends on [libsodium](https://download.libsodium.org/doc/), an awesome crypto library. These need to be installed separately. - Plenum uses [ZeroMQ](http://zeromq.org/) as a secure transport - [indy-crypto](https://github.com/hyperledger/indy-crypto) - A shared crypto library - It's based on [AMCL](https://github.com/milagro-crypto/amcl) - In particular, it contains BLS multi-signature crypto needed for state proofs support in Indy. ## Contact Us - Bugs, stories, and backlog for this codebase are managed in [Hyperledger's Jira](https://jira.hyperledger.org). Use project name `INDY`. - Join us on [Jira's Rocket.Chat](https://chat.hyperledger.org/channel/indy) at `#indy` and/or `#indy-node` channels to discuss. ## How to Contribute - We'd love your help; see these [instructions on how to contribute](http://bit.ly/2ugd0bq). - You may also want to read this info about [maintainers](https://github.com/hyperledger/indy-node/blob/stable/MAINTAINERS.md). ## How to Start Working with the Code Please have a look at [Dev Setup](https://github.com/hyperledger/indy-node/blob/master/docs/setup-dev.md) in indy-node repo. It contains common setup for both indy-plenum and indy-node. ## Try Plenum Locally #### Install from pypi ``` pip install indy-plenum ``` From here, you can play with the command-line interface (see the [tutorial](https://github.com/hyperledger/indy-plenum/wiki)). Note: For Windows, we recommended using either [cmder](http://cmder.net/) or [conemu](https://conemu.github.io/). ``` plenum ``` ...or run the tests. ``` git clone https://github.com/hyperledger/indy-plenum.git cd indy-plenum python -m plenum.test ``` #### Initializing Keys Each Node needs to have keys initialized - ed25519 transport keys (used by ZMQ for Node-to-Node and Node-to-Client communication) - BLS keys for BLS multi-signature and state proofs support ``` init_plenum_keys --name Alpha --seeds 000000000000000000000000000Alpha Alpha000000000000000000000000000 --force ``` ``` init_plenum_keys --name Beta --seeds 0000000000000000000000000000Beta Beta0000000000000000000000000000 --force ``` ``` init_plenum_keys --name Gamma --seeds 000000000000000000000000000Gamma Gamma000000000000000000000000000 --force ``` ``` init_plenum_keys --name Delta --seeds 000000000000000000000000000Delta Delta000000000000000000000000000 --force ``` Note: Seed can be any randomly chosen 32 byte value. It does not have to be in the format `00..<name of the node>`. #### Seeds used for generating clients 1. Seed used for steward Bob's signing key pair ```11111111111111111111111111111111``` 2. Seed used for steward Bob's public private key pair ```33333333333333333333333333333333``` 3. Seed used for client Alice's signing key pair ```22222222222222222222222222222222``` 4. Seed used for client Alice's public private key pair ```44444444444444444444444444444444``` #### Running Node ``` start_plenum_node Alpha ``` #### Updating configuration To update any configuration parameters, you need to update the `indy_config.py` in `.plenum/YOUR_NETWORK_NAME` directory inside your home directory. eg. To update the node registry to use `127.0.0.1` as host put these in your `indy_config.py`. ```python from collections import OrderedDict nodeReg = OrderedDict([ ('Alpha', (('127.0.0.1', 9701), '0490a246940fa636235c664b8e767f2a79e48899324c607d73241e11e558bbd7', 'ea95ae1c913b59b7470443d79a6578c1b0d6e1cad0471d10cee783dbf9fda655')), ('Beta', (('127.0.0.1', 9703), 'b628de8ac1198031bd1dba3ab38077690ca9a65aa18aec615865578af309b3fb', '18833482f6625d9bc788310fe390d44dd268427003f9fd91534e7c382501cd3c')), ('Gamma', (('127.0.0.1', 9705), '92d820f5eb394cfaa8d6e462f14708ddecbd4dbe0a388fbc7b5da1d85ce1c25a', 'b7e161743144814552e90dc3e1c11d37ee5a488f9b669de9b8617c4af69d566c')), ('Delta', (('127.0.0.1', 9707), '3af81a541097e3e042cacbe8761c0f9e54326049e1ceda38017c95c432312f6f', '8b112025d525c47e9df81a6de2966e1b4ee1ac239766e769f19d831175a04264')) ]) cliNodeReg = OrderedDict([ ('AlphaC', (('127.0.0.1', 9702), '0490a246940fa636235c664b8e767f2a79e48899324c607d73241e11e558bbd7', 'ea95ae1c913b59b7470443d79a6578c1b0d6e1cad0471d10cee783dbf9fda655')), ('BetaC', (('127.0.0.1', 9704), 'b628de8ac1198031bd1dba3ab38077690ca9a65aa18aec615865578af309b3fb', '18833482f6625d9bc788310fe390d44dd268427003f9fd91534e7c382501cd3c')), ('GammaC', (('127.0.0.1', 9706), '92d820f5eb394cfaa8d6e462f14708ddecbd4dbe0a388fbc7b5da1d85ce1c25a', 'b7e161743144814552e90dc3e1c11d37ee5a488f9b669de9b8617c4af69d566c')), ('DeltaC', (('127.0.0.1', 9708), '3af81a541097e3e042cacbe8761c0f9e54326049e1ceda38017c95c432312f6f', '8b112025d525c47e9df81a6de2966e1b4ee1ac239766e769f19d831175a04264')) ]) ```
