You have 5 steps to build application.
- Build blockchain and node
- Deploy contract
- Set up firestore
- Set up elasticsearch
- Set up frontend
git clone [email protected]:gaiax/fLibra.git
cd fLibra
Install ethereum
brew tap ethereum/ethereum
brew install ethereum
Make flibrachain
directory, and create a geth account for development.
$ mkdir flibrachain
$ geth account new --datadir ./flibrachain/node1
INFO [12-20|11:37:00.688] Maximum peer count ETH=25 LES=0 total=25
Your new account is locked with a password. Please give a password. Do not forget this password.
Passphrase:
Repeat passphrase:
Address: {57da1c524a3e762a8921983f52d3ce21672357f7}
$ cd flibrachain
$ puppeth
Set a network name. In this case, I named "flibrachain"
Please specify a network name to administer (no spaces, hyphens or capital letters please)
>flibrachain
Type "2" to generate new genecis block.
What would you like to do? (default = stats)
1. Show network stats
2. Configure new genesis
3. Track new remote server
4. Deploy network components
> 2
Type "1".
What would you like to do? (default = create)
1. Create new genesis from scratch
2. Import already existing genesis
> 1
Type "2" to choose PoA consensus algorithm.
Which consensus engine to use? (default = clique)
1. Ethash - proof-of-work
2. Clique - proof-of-authority
> 2
How many seconds should blocks take? (default = 15)
> 5
Type the address that you created before, and press enter twice.
Which accounts are allowed to seal? (mandatory at least one)
> 0x4d8c003c1dc28a28a323873752e2b07c2cf3d413
> 0x
Again
Which accounts should be pre-funded? (advisable at least one)
> 0x4d8c003c1dc28a28a323873752e2b07c2cf3d413
> 0x
Should the precompile-addresses (0x1 .. 0xff) be pre-funded with 1 wei? (advisable yes)
> yes
Type network id.
Specify your chain/network ID if you want an explicit one (default = random)
>1515
Next, type "2" to manage genecis block.
What would you like to do? (default = stats)
1. Show network stats
2. Manage existing genesis
3. Track new remote server
4. Deploy network components
> 2
Then, export information of genesis block
1. Modify existing fork rules
2. Export genesis configurations
3. Remove genesis configuration
> 2
If you don't mind where those will be save, press enter.
Which folder to save the genesis specs into? (default = current)
Will create flibrachain/.json, flibrachain/-aleth.json, flibrachain/-harmony.json, flibrachain/-parity.json

IINFO [12-20|22:54:03.661] Saved native genesis chain spec path=privateconsortium.json
ERROR[12-20|22:54:03.662] Failed to create Aleth chain spec err="unsupported consensus engine"

Initialize a node.
$ cd flibrachain
$ geth --datadir node1 init flibrachain.json
Start up geth
geth --datadir node1/ --syncmode 'full' --port 30311 --rpc --rpcaddr '0.0.0.0' --rpcport 8545 --rpccorsdomain "*" --rpcvhosts "*" --rpcapi 'personal,db,eth,net,web3,txpool,miner' --ws --wsapi 'eth,web3,net' --wsorigins='*' --wsaddr='0.0.0.0' --wsport 8546 --networkid 1515 --gasprice '0'
In another tab, start mining to build blockchain
$ cd flibrachain
$ geth attach ipc:node1/geth.ipc
Welcome to the Geth JavaScript console!
Unlock your account
> personal.unlockAccount(eth.coinbase,"Password",0)
true
Set default account
> eth.defaultAccount = eth.coinbase
0x4d8c003c1dc28a28a323873752e2b07c2cf3d413
Start mining
> miner.start()
null
You can see how many blocks blockchain has like this.
eth.blockNumber
cd flibrachain
geth --datadir node1/ --syncmode 'full' --port 30311 --rpc --rpcaddr '0.0.0.0' --rpcport 8545 --rpccorsdomain "*" --rpcvhosts "*" --rpcapi 'personal,db,eth,net,web3,txpool,miner' --ws --wsapi 'eth,web3,net' --wsorigins='*' --wsaddr='0.0.0.0' --wsport 8546 --networkid 1515 --gasprice '0'
geth attach ipc:node1/geth.ipc
> personal.unlockAccount(eth.coinbase,"Sample",0)
> miner.start()
Block gas limit is guradually increase, so you may have to wait until block gas limit reaaches at 8000000

Move on truffle directory and install dependencies.
$ cd truffle
$ npm i
MNEMONIC = "receive risk draw record wheel ... benefit broccoli cruel net present topic"
truffleEndpoint = http://0.0.0.0:8545
Please use your mnemonic phrase.
$ npm start
If you successfully deployed contract, you can find JSON file in "../frontend/abis/"
Please create a project on Firebase. https://firebase.google.com/docs/firestore/quickstart
Connect your repository with firebase project
npm install -g firebase-tools
// or
yarn add firebase-tools
firebase login
firebase init
If you already installed elasticsearch, you can skip this step.
Install elasticsearch https://www.elastic.co/guide/en/elasticsearch/reference/7.4/brew.html
Install kuromoji https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-kuromoji.html
cd /usr/local/var/homebrew/linked/elasticsearch-full //please find your path
curl -XPUT 'localhost:9200/flibra?pretty'
