Lightning Demo

1.Get the box

​ Build it yourself:

git clone https://github.com/ccyanxyz/lightning-testnet-box.git
cd lightning-testnet-box
docker build -t lightning-testnet-box .

​ OR pull the image from docker hub:

docker pull ccyanxyz/lightning-testnet-box:latest

2.Start everything

​ Start the container:

docker run -it lightning-testnet-box

​ Start bitcoind & lightningd:

make start-bitcoind
make start-lightningd

3.Generate some blocks

​ Make them rich:

b1 generate 100 # alias to bitcoin-cli -datadir=/root/lightning-testnet-box/node1, see .bashrc
b2 generate 100
b3 generate 100
b4 generate 101

4.State channel

​ Generate new address and send some bitcoin to the address:

l1 newaddr
b1 sendtoaddress <ADDRESS> <AMOUNT IN BITCOIN>
b1 generate 6 # make sure the tx is confirmed
l1 listfunds # list the output, if empty, just wait a minute and try again

​ Connect to node2 and fund channel:

l2 getinfo # copy the id of lightning node2
l1 connect <PEER ID>@127.0.0.1:9736
l1 fundchannel <PEER ID> <AMOUNT IN SAT>
l1 listfunds # channels is open now

​ Assume that node1 have to pay node2 some btc, node2 has to generate an invoice:

l2 invoice <AMOUNT IN mSAT> <LABEL> <DESCRIPTION>

​ Now node1 can pay node2 use the serialized invoice ‘bolt11’:

l1 decodepay <BOLT11> # inspect the content of the serialized invoice
l1 getroute <PEER ID> <AMOUND IN mSAT> <RISK FACTOR>
l1 pay <BOLT11>
l2 listfunds # now node2 should have received the money, see 'channel_sat'

​ Close channel:

l1 close <PEER ID>
b1 generate 101
l1 listfunds # now the channel should be closed

5.Make a network of lightning nodes

​ Lazy… TBD…
