Registry

Registry is a custom blockchain built using the Cosmos SDK. It currently houses SDK modules and CLI toolchain for Registry and Payments.

Setup & install

Install golang 1.11+ for your platform.

$ go version
go version go1.11 darwin/amd64

Clone the repo.

$ mkdir -p $GOPATH/src/github.com/wirelineio
$ cd $GOPATH/src/github.com/wirelineio
$ git clone git@github.com:wirelineio/registry.git

Initialize dep and install dependencies.

$ cd registry
$ make get_tools && make get_vendor_deps

Install the app into your $GOBIN.

$ make install

Test that the commands are installed.

$ registryd help
$ regcli help

Initialize & start blockchain

Delete existing blockchain and config.

$ rm -rf ~/.registryd/ ~/.regcli

Initialize the chain.

$ registryd init --chain-id wireline

Setup accounts/keys for Alice & Bob. Enter a passphrase for the key when prompted.

$ regcli keys add alice

$ regcli keys add bob

Add initial funds to the accounts.

$ registryd add-genesis-account $(regcli keys show alice --address) 1000000wire

Start the blockchain. You should see blocks being created every few seconds.

$ registryd start --gql-server --gql-playground

Run the following commands in another terminal.

Registry module

Get Bob's address and public key.

$ regcli query registry key bob
Address   : 002aee66c9908426658a39d7e95a48646d172d0f
PubKey    : 61rphyED+i6I7SuuyeuX9Zgsww9WnXi3BOpxhyEWpnI4kZEfNGY=

Sign the resource with Bob's credentials.

$ regcli tx registry set service1.yml --from bob --sign-only
Password to sign with 'bob':
Address   : 002aee66c9908426658a39d7e95a48646d172d0f
PubKey    : 61rphyED+i6I7SuuyeuX9Zgsww9WnXi3BOpxhyEWpnI4kZEfNGY=
Signature : iYlLCgiqNL1vsm+3u7alGFNzZJD+u/vlM/YwdJfYAfZAwtChAOUQK3pWlIBIDsmqqwuqV5tK5pDrDcA5zT0swQ==

Update the resource payload (e.g. service1.yml) with Bob's address, public key and signature.

• Set resource/owner to Bob's address.
• Set signature pubKey and sig using output from the previous command.

# service1.yml
record:
  id: wrn:record:05013527-30ef-4aee-85d5-a71e1722f255
  type: wrn:registry-type:service
  owner: 02e840ed2d4c3e0b4e068f0d4be811b095ec78d5
  attributes:
    label: Weather

signatures:
  -
    pubKey: 61rphyEDI/Iy96OBr9fn11ADRfDPUgAiEW5MdETVuK9PohsxWMU=
    sig: r3J9Hi+1nyO86Gbdo0jRuxzU1zHRzEvtK3EqH2x9owQ9NNvzQp7BeBLyInASgwEDHu4Iec21fzRR8klHbDN5Sw==

Publish resource record.

$ regcli tx registry set service1.yml --from alice

Get resource record by ID.

$ regcli query registry get wrn:record:05013527-30ef-4aee-85d5-a71e1722f255

List resource records.

$ regcli query registry list

Generate resource graph.

$ regcli query registry graph | dot -Tpng  > test.png && eog test.png

Generate graph, starting from a particular resource.

$ regcli query registry graph wrn:record:05013527-30ef-4aee-85d5-a71e1722f255 | dot -Tpng  > test.png && eog test.png

Delete resource record.

$ regcli tx registry delete service1.yml --from alice

Clear all resource records (Warning: This bypasses all access checks and is for local testing purposes only).

$ regcli tx registry clear --from alice

GQL Server API

The GQL server is controlled using the following registryd flags:

• --gql-server - Enable GQL server.
• --gql-playground - Enable GQL playground app (Available at http://localhost:8080/).
• --gql-port - Port to run the GQL server on (default 8080).

See registryd/x/registry/gql/schema.graphql for the GQL schema.

Testnets

Development

Endpoints

• GQL: https://registry-testnet.dev.wireline.ninja/query
• GQL Playground: https://registry-testnet.dev.wireline.ninja/
• RPC: tcp://registry-testnet.dev.wireline.ninja:26657

Production

Endpoints

• GQL: https://registry-testnet.wireline.ninja/query
• GQL Playground: https://registry-testnet.wireline.ninja/
• RPC: tcp://registry-testnet.wireline.ninja:26657

Note: The regcli command accepts a --node flag for the RPC endpoint.

Faucet

The testnets come with a seed account (alice) that can be used to transfer funds to a new account. Run these commands locally to restore Alice's keys on your own machine to transfer funds.

$ regcli keys add alice --recover

# Use the following mnemonic for recovery:
# salad portion potato insect unknown exile lion soft layer evolve flavor hollow emerge celery ankle sponsor easy effort flush furnace life maximum rotate apple

$ regcli tx send --amount 1000wire --to cosmos1lpzffjhasv5qhn7rn6lks9u4dvpzpuj922tdmy --from alice --chain-id=wireline --node tcp://registry-testnet.wireline.ninja:26657

# Replace cosmos1lpzffjhasv5qhn7rn6lks9u4dvpzpuj922tdmy with the address you want to transfer funds to.
