# BSP-spec
Goal: a Protobuf spec of https://code.briarproject.org/briar/briar-spec/blob/master/protocols/BSP.md
2019-01-14 04:06:51 +00:00
As well as some PoC around it.
Initial PoC report: https://notes.status.im/THYDMxSmSSiM5ASdl-syZg

## Setup
2018-12-18 03:47:59 +00:00
```
2019-02-25 03:37:39 +00:00
# ensure you have protobuf-compiler, python3, pip installed
# Using virtualenv
python3 -m pip install --user virtualenv
python3 -m virtualenv env
source env/bin/activate
pip install web3 protobuf
2018-12-18 03:47:59 +00:00
make
2019-02-25 03:37:39 +00:00
#make run # see sync.py
# or:
python3 app.py < a | b >

## Whisper
Run geth node:
```
geth --testnet --syncmode=light --ws --wsport=8546 --wsaddr=localhost --wsorigins=statusjs --rpc --maxpeers=25 --shh --shh.pow=0.002 --wsapi=eth,web3,net,shh,debug,admin,personal
```
geth --testnet --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8501
```
geth --testnet --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8500 --datadir=/tmp/foo --port=30000
geth --testnet --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8501 --datadir=/tmp/bar --port=30001
- add nodes to connect
- running whisper node on own nodes?

## Setup
This assumes:
```
cp static-nodes.json ~/.ethereum/node-a/
cp static-nodes.json ~/.ethereum/node-b/
```
FIXME: toml config?
```
WARN [02-21|03:27:02.567] Found deprecated node list file /tmp/node-b/static-nodes.json, please use the TOML config file instead.

TODO: Consider lowering PoW, but am I even connected to each other?
Can manually hack I guess - what is my enode?

Ok, not working. Trying to add peer but no luck
admin.addPeer("enode://01acca361b49bdf611a8ce3f39beaac712bdfefa0d552f25fc7c54217a9e678a9233f0b1622d0c489ff022f7a6ad7387203d45edc000edbf066ff246d35d5e1a@127.0.0.1:30000")

ok, so this works.
Problem: even with detailed logs very little feedback
If I cal lwith al lthis sync node etc no worky
geth --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8501 --datadir=~/.ethereum/node-b --port=30001 --vmodule eth/*=2,p2p=4,shh=5,whisper=5 & > node-b.log
ANd addpeer
## Gethy
How to start:
```
geth --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8501 --datadir=~/.ethereum/node-b --port=30001 --vmodule eth/*=2,p2p=4,shh=5,whisper=5 & > node-b.log
```
or use scripts, look in folder.
```
./scripts/start-node-b.sh & > node-b.log &
```
How to attach:
```
geth --rpc --maxpeers=25 --shh --shh.pow=0.002 --rpcport=8501 --datadir=~/.ethereum/node-b --port=30001 attach
```
admin.addPeer("enode://421a707a09d9ff08028fd9e47df876bd4cfbd873ce12cfe00702b068acf077518c5c065fb94b61782287695e276973dfa0361c81227d2e7c0570deedfbe7dbb@127.0.0.1:30001");
admin.addPeer("enode://421a707a09d9ff08028fd9e47df876bd4cfbd873ce12cfe00702b068acf077518c5c065fb94b61782287695e276973edfa0361c81227d2e7c0570deedfbe7dbb@127.0.0.1:30001");

And if I restart node it disconnects previous ones...
Why?

## Next steps
- End to end add several notes
- Sanity check wrt adding peers manually etc
2019-02-25 03:37:39 +00:00
- Figure out latency smaller
