ResselChain
2+
===
3+
4+
This is an implementation of a private permissioned blockchain in Java.
5+
6+
Dependencies
7+
---
8+
ResselChain depends on the following software:
9+
- Java8
10+
- Sqlite Jdbc 3.19.3
11+
- Xom 1.2.10
12+
13+
How to run
14+
---
15+
16+
1. Download the necessary dependencies and store them in ./lib.
17+
2. Invoke the *init*, *unjar_dependencies*, *jars*, *compile* Ant Build targets in this order.
18+
3. To implement your own consensus algorithm and state storage, see file *./src/statetable/AssetStateTable.java*.
19+
4. Place the configuration for all nodes in ./conf (see nodeExample.xml and all.xml). You may use *GenerateKeyPair.java* in ./src/main to generate key pairs.
20+
5. Run *RC.jar* from the build directory. (`java -jar RC.jar conf/nodeExample.xml conf/all.xml`)
21+
22+
a) Use *UtilityTxSender.jar* to determine a default distribution of assets.
23+
24+
b) Use *TxSender.jar* to send assets to other participants.
25+
26+
c) Use *Status.jar* to observe the status of a node.
27+
28+
d) Use *Amount.jar* to see the distribution of assets.
29+
30+
e) Optionally use *BlockList.jar* and *XMLSender.jar* for debugging.
