master	develop

Cocos-BCX is the next generation gaming digital economy platform. The project aims to provide game developers with an easy-to-use, comprehensive blockchain gaming infrastructure. Provide gamers with a transparent, fair, and open game environment. The underlying chain system is based on graphene for the optimization of consensus mechanisms and the addition of intelligent contract systems. And provide a lot of game features, such as random number, contract session mechanism, timer, and heartbeat.

Getting Started

Preparation

We recommend building on Ubuntu 16.04 LTS (64-bit)

sudo apt-get update
sudo apt-get install autoconf cmake git vim libbz2-dev libdb++-dev libdb-dev
libssl-dev openssl libreadline-dev libtool libcurl4-openssl-dev libboost-all-dev

Building the source

cmake -DBUILD_PROCESS_ENCRYPTION=NO .  
make  

After Building, the witness_node can be launched with:

./programs/witness_node/witness_node  

The node will automatically create a data directory including a config file. It may take several hours to fully synchronize the blockchain. After syncing, you can exit the node using Ctrl+C and setup the command-line wallet by editing witness_node_data_dir/config.ini as follows:

rpc-endpoint = 127.0.0.1:8090  

notice：Please note that currently(2019-11-19) a full node will need more than 16GB of RAM to operate and required memory is growing fast. Consider the following table as minimal requirements before running a node:

Default	Full	Minimal	ElasticSearch
100G HDD, 16G RAM	640G SSD, 64G RAM *	80G HDD, 4G RAM	500G SSD, 32G RAM

After starting the witness node again, in a separate terminal you can run:

./programs/cli_wallet/cli_wallet  

Set your inital password:

>>> set_password <PASSWORD>  
>>> unlock <PASSWORD>  

To import your initial balance:

>>> import_balance <ACCOUNT NAME> [<WIF_KEY>] true  

If you send private keys over this connection, rpc-endpoint should be bound to localhost for security.
Use help to see all available wallet commands. Source definition and listing of all commands is available here

Using the API

We provide several different API's. Each API has its own ID. When running witness_node, initially two API's are available: API 0 provides read-only access to the database, while API 1 is used to login and gain access to additional, restricted API's.

Here is an example using wscat package from npm for websockets:

$ npm install -g wscat
$ wscat -c ws://127.0.0.1:8090
> {"id":1, "method":"call", "params":[0,"get_accounts",[["1.2.0"]]]}
< {"id":1,"result":[{"id":"1.2.0","annotations":[],"membership_expiration_date":"1969-12-31T23:59:59","registrar":"1.2.0","referrer":"1.2.0","lifetime_referrer":"1.2.0","network_fee_percentage":2000,"lifetime_referrer_fee_percentage":8000,"referrer_rewards_percentage":0,"name":"committee-account","owner":{"weight_threshold":1,"account_auths":[],"key_auths":[],"address_auths":[]},"active":{"weight_threshold":6,"account_auths":[["1.2.5",1],["1.2.6",1],["1.2.7",1],["1.2.8",1],["1.2.9",1],["1.2.10",1],["1.2.11",1],["1.2.12",1],["1.2.13",1],["1.2.14",1]],"key_auths":[],"address_auths":[]},"options":{"memo_key":"GPH1111111111111111111111111111111114T1Anm","voting_account":"1.2.0","num_witness":0,"num_committee":0,"votes":[],"extensions":[]},"statistics":"2.7.0","whitelisting_accounts":[],"blacklisting_accounts":[]}]}

We can do the same thing using an HTTP client such as curl for API's which do not require login or other session state:

$ curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0, "get_accounts", [["1.2.0"]]], "id": 1}' http://127.0.0.1:8090/rpc
{"id":1,"result":[{"id":"1.2.0","annotations":[],"membership_expiration_date":"1969-12-31T23:59:59","registrar":"1.2.0","referrer":"1.2.0","lifetime_referrer":"1.2.0","network_fee_percentage":2000,"lifetime_referrer_fee_percentage":8000,"referrer_rewards_percentage":0,"name":"committee-account","owner":{"weight_threshold":1,"account_auths":[],"key_auths":[],"address_auths":[]},"active":{"weight_threshold":6,"account_auths":[["1.2.5",1],["1.2.6",1],["1.2.7",1],["1.2.8",1],["1.2.9",1],["1.2.10",1],["1.2.11",1],["1.2.12",1],["1.2.13",1],["1.2.14",1]],"key_auths":[],"address_auths":[]},"options":{"memo_key":"GPH1111111111111111111111111111111114T1Anm","voting_account":"1.2.0","num_witness":0,"num_committee":0,"votes":[],"extensions":[]},"statistics":"2.7.0","whitelisting_accounts":[],"blacklisting_accounts":[]}]}

API 0 is accessible using regular JSON-RPC:

$ curl --data '{"jsonrpc": "2.0", "method": "get_accounts", "params": [["1.2.0"]], "id": 1}' http://127.0.0.1:8090/rpc
