Crypto-Wills

Crypto-Wills use blockchain: technology that stores information in a decentralized form where information is parceled up in blocks. This decentralized distributed ledger is so attractive because of its transparency, security, and resistance to modification, transparency and security. If anyone tries to change an entry, the attempt is flagged by the system and the authenticity of the attempt is verified.

How to start

Running with Vagrant

1. Install VirtualBox

2. Install Vagrant

3. Download and start the Vagrant instance (note: running vagrant up takes approx 5 mins):

   cd quorum
   vagrant up
   vagrant ssh

4. To shutdown the Vagrant instance, run vagrant suspend. To delete it, run vagrant destroy. To start from scratch, run vagrant up after destroying the instance.

Starting the 7nodes sample network

1. Navigate to the 7nodes example directory, configure the Quorum nodes and initialize accounts & keystores:

   cd path/to/7nodes
   ./{consensus}-init.sh

2. Start the Quorum and privacy manager nodes (Constellation or Tessera):

   • If running in Vagrant:

     ./{consensus}-start.sh

     By default, Tessera will be used as the privacy manager. To use Constellation run the following:

     ./{consensus}-start.sh constellation
     

   • If running locally:

     ./{consensus}-start.sh tessera --tesseraOptions "--tesseraJar /path/to/tessera-app.jar"
     

     By default, {consensus}-start.sh will look in /home/vagrant/tessera/tessera-app/target/tessera-app-{version}-app.jar for the Tessera jar. --tesseraOptions must be provided so that the start script looks in the correct location for the Tessera jar:

     Alternatively, the Tessera jar location can be specified by setting the environment variable TESSERA_JAR.

3. You are now ready to start sending private/public transactions between the nodes Clone or download respository

##Add website and contracts

1. Clone my respository

   git clone https://github.com/MrRav3n/Crypto-Wills.git

2. Install dependencies

   yarn install or npm install

3. Use yarn start to open your development server

   yarn start or npm start

4. With Metamask connect to proper node (first is http://127.0.0.1:22000 second http://127.0.0.1:22001 eth.)

5. Truffle migrate project

   truffle migrate --compile-all --reset
