Road Test notepad: Infineon Blockchain Starter Kit

Jan Cumps
Jan Cumps
14 Mar 2022

This document is a scrapbook for the Infineon Blockchain Starter Kit road test.

 

 

 

1 (YES) see if it is possible to run a blockchain ledger on a Raspberry Pi

 

Before applying (check this thread that shows several people moving from not interested to interested) we floated some balloons on how to use the kit to show a real world case, and how we could learn from it.

The project will try using hyperledger and blockchain to create a record of trusted transactions.

 

 

install hyperledger burrow https://wiki.hyperledger.org/display/burrow

dependency for docker: python 3.6. I don't know if docker is needed , because you can also install from binary and source...

 

Not needed with latest raspbian. It has version 3.7.

 

Install python 3.6

 

 

https://gist.github.com/dschep/24aa61672a2092246eaca2824400d37f

dependency for hyperledger

 

Install docker and docker-compose

 

Not needed if build from source.

 

 

 

https://withblue.ink/2019/07/13/yes-you-can-run-docker-on-raspbian.html

 

 

 

docker-compose --version

If Java is a prereq (yes for the SDK, no for Burrow, I believe):

 

sudo apt-get install -y openjdk-11-jdk

If building from source

 

 

needed if build from source.

 

sudo apt install git

 

 

get go https://golang.org/doc/install

 

nano ~/.bashrc

 

#20200203 jc added  $GOPATH
export GOPATH=$HOME/go

source ~/.bashrc

For deploying contracts you will need a local installation of Solidity

 

https://solidity.readthedocs.io/en/v0.6.2/installing-solidity.html

 

failed with ubuntu and docker image

 

snap: install of snap worked but then the instal of solc not

sudo apt-get install snap

Ah, needs snapd:

 

sudo apt-get install snapd


sudo snap install solc

 

 

 

2020-02-03T19:44:25+01:00 INFO Waiting for restart...
solc v0.5.2 from Ethereum Build Automation (builds-c) installed

 

There's an error message.

pi@raspberrypi:~ $ snap run solc
ERROR: ld.so: object '/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object '/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
solc, the Solidity commandline compiler.

 

 

 

I may have a different version than latest raspberry now because I ran sudo raspi-update, as advised by

https://stackoverflow.com/questions/42443273/raspberry-pi-libarmmem-so-cannot-open-shared-object-file-error

 

sudo mv /etc/ld.so.preload /etc/ld.so.preloadbak

Now Burrow

from source: https://github.com/hyperledger/burrow/tree/master/docs#source

 

 

go get github.com/hyperledger/burrow
cd $GOPATH/src/github.com/hyperledger/burrow
make build

To install in ~/go/bin:

 

make install

 

 

Yay

 

pi@raspberrypi:~/go/bin $ ./burrow --version

 

0.29.7+commit.v0.29.7-2-gbfa9180e+2020-02-03

Start a session; for test only

 

The genesys is lost after doing this , so you can't restart burrow. Delete the .burrow subfolder for a fresh start

 

pi@raspberrypi:~/go/bin $ ./burrow spec -v1 | ./burrow configure -s- | ./burrow start -c-

A test:

 

pi@raspberrypi:~/go/bin $ ./burrow accounts
Account: 0000000000000000000000000000000000000000
  Sequence: 0


Account: 13B9648F4115CBB6E8671AD12012877952B5A995
  Sequence: 0

 

A reusable (not tested in any way for safety!!!) run seed

cd ~/go/bin

 

Creating a reusable Genesis config file

./burrow spec -v1 | ./burrow configure -s- > startup.cfg

 

Running and rerunning that burrow , restoring the database:

cat startup.cfg | ./burrow start -c-

 

If you'd rather want to run that as a background process:

cat startup.cfg | ./burrow start -c-  > ./burrow.log &

 

You can then check the log by executing

tail -f ./burrow.log

 

 

Get info, from browser (replace with your Pi's IP). If you use chrome, install JSON viewer plugin. FF has a default viewer.

http://192.168.1.10:26658

 

or from the linux prompt

curl localhost:26658/status

 

Web3: Ethereum interface

http://192.168.1.10:26660/

Tutorial: https://hyperledger.github.io/burrow/#/

 

Prereq: JSON processor:

sudo apt-get install jq

 

When doing the Bonding example, check the errata in https://github.com/hyperledger/burrow/issues/1316

instead of

burrow tx --config burrow001.toml formulate bond --amount 10000 | burrow tx commit

 

do this:

burrow tx --config burrow001.toml formulate bond --amount 10000 > tx.json
burrow tx --config burrow001.toml commit --file tx.json

 

 

Trying to link 2, with a seeds node: https://github.com/silasdavis/burrow/blob/develop/docs/tutorials/6-seed-nodes.md

 

 

todo: show content

 

Restart with the 3 files after the seed substitution has been done once:

killall burrow
rm -rf .burrow_node0 .burrow_node1 .burrow_node2 .burrow_seed_0
OLD_URL=$SEED_URL
burrow start --address=`basename .keys_seed/data/* .json` --config=.burrow_seed.toml  > .burrow_seed.log 2>&1 &
SEED_URL=`curl -s 127.0.0.1:10001/network | jq -r '.result.ThisNode | [.ID, .ListenAddress] | join("@") | ascii_downcase'`
sed -i s%${OLD_URL}%${SEED_URL}% .burrow_val0.toml

sed -i s%${OLD_URL}%${SEED_URL}% .burrow_val1.toml

sed -i s%${OLD_URL}%${SEED_URL}% .burrow_val2.toml

burrow start -v=0 --config=.burrow_val0.toml  > .burrow_val0.log 2>&1 &
burrow start -v=1 --config=.burrow_val1.toml  > .burrow_val1.log 2>&1 &
burrow start -v=2 --config=.burrow_val2.toml  > .burrow_val2.log 2>&1 &

curl -s 127.0.0.1:40001/network | jq -r '.result.peers[].node_info.moniker'
curl -s 127.0.0.1:10001/network | jq -r '.result.peers[].node_info.moniker'
curl -s 127.0.0.1:10001/consensus | jq -r '.result.round_state.height'

 

 

2. to see if I can write to my cardreader in linux

Readers advised by Infineon: https://ccid.apdu.fr/select_readers/?features=contactless

 

This will need rework because the reader I have will not do in its current form

 

3 SC/PC setup on Linux

 

The Infinione examples use a python library based on SC/PC.

This is a set of libraries and a service that support accessing card readers and talking to cards.

I have not been able to run this with a smart RFC card reader yet. It works with the ID card reader for Belgian id cards

 

Tested on Ubuntu VM on my windows 10 laptop

 

Software needed:

 

Instructions: https://github.com/Infineon/BlockchainSecurity2Go-Python-Library

 

sudo apt-get install swig
pip3 install blocksec2go

install PCSC-lite.

service pcscd (start as sudo)

4a. (NO) See if hyperledger fabric can run on a raspberry pi

 

Prereqs: https://hyperledger-fabric.readthedocs.io/en/release-2.0/prereqs.html

(I had everything from installing Burrow, except the golang version. I had 1.11x and 1.13 or higher is needed

nano ~/.profile

 

# 20200229 jc: set PATH so it includes GO
PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

 

NPM and node.js needed

 

sudo apt-get install npm

 

pi@raspberrypi:~/go/bin $ node -v
v10.15.2
pi@raspberrypi:~/go/bin $ npm -v
5.8.0

 

Proceed with Fabric: https://hyperledger-fabric.readthedocs.io/en/release-2.0/getting_started.html

 

 

clone the fabric_samples, then follow instructions in the readme https://github.com/hyperledger/fabric-samples

git clone https://github.com/hyperledger/fabric-samples.git

 

 

https://medium.com/swlh/hyperledger-chapter-7-installing-hyperledger-fabric-89430e61b7bb

git clone -b master https://github.com/hyperledger/fabric-samples.git

cd fabric-samples

git checkout 1.3.0-rc1

 

then stuck at the next command because the dowload folder is gone https://github.com/hyperledger/fabric/releases/download/

 

The best step guide I found is this one:

https://www.joemotacek.com/hyperledger-fabric-v1-0-on-a-raspberry-pi-docker-swarm-part-1/

 

unfortunately, hyperledger has just sunset their maven repos on nexus, and the scripts depend on them, so stuck. (https://www.joemotacek.com/hyperledger-fabric-v1-0-on-a-raspberry-pi-docker-swarm-part-2/#comment-16765 , under moderation)

 

4b. (YES) on a ubuntu VM

 

prereqs: git, wget, docker, docker-compose, go

 

I followed the instructions for version 2: https://hyperledger-fabric.readthedocs.io/en/release-2.0/getting_started.html

both prereqs and getting started
