4. Deploy TL.md

Create national Trusted List

This tutorial describes the steps to deploy a regional Public Key Directory (PKD) smart contract in order to build a Root of Trust using the SSI API.

Pre-requisites

• ssi-api: to see how to install and run the REST API go to the official repository: https://github.com/lacchain/ssi-api

Note: This tutorial assumes that you have the API running at http://localhost:8080.

Deploy a new TL

To deploy a new Trusted List smart contract you need to specify the parent TL or PKD address and the new TL name, if you don't have or don't want to specify a parent element just use the Ethereum zero address (0x0000000000000000000000000000000000000000). To create the TL execute the next command:

curl -X POST -H "Content-Type: application/json" -d '{"parent":"0x723a4739588c49476D3AEFEB6562d2f2DB50b314", "name":"National TL 1"}' http://localhost:8080/pki/tl/deploy

This command will return the TL address and blockchain transaction hash, as it is show in the next image:

Now that you have deployed the TL and linked to another TL or PKD by it parent property, it is necessary to link reversely in the parent element by Register a TL in a PKD.

List deployed TLs

To view the list of all TLs deployed, execute the next command:

curl -X GET http://localhost:8080/pki/tl

This command will return an array of TL with: name, address and parent TL or PKD address, as it is show in the next image:
