TESTS

rm -rf ~/.nsd/config/genesis.json
nsd init syzer --chain-id buildings
nscli keys add jack < .secret_password
nscli keys add alice < .secret_password
nsd add-genesis-account (nscli keys show jack -a) 1000nametoken,100000000stake

nsd start

check if jack/alice have funds

nscli query account (nscli keys show jack -a) nscli query account (nscli keys show alice -a)

nscli tx nameservice buy-location AlexPlatz1 5nametoken 52.521918 13.413215 --from jack
nscli tx nameservice buy-location BrandenburgerTor1 5nametoken 52.516275 13.377704 --from jack

SET DAG

nscli tx nameservice set-dag AlexPlatz1 (cat ./data/dag.json) --from jack --gas 20000000000 nscli tx nameservice set-dag BrandenburgerTor1 (cat ./data/dag.json) --from jack --gas 20000000000 nscli query nameservice resolve AlexPlatz1

nscli query nameservice whois AlexPlatz1

bid/buy buildings

nscli tx nameservice buy-location AlexPlatz1 10nametoken 52.521918 13.413215 --from alice

REST

nscli rest-server --chain-id buildings --trust-node

Tests

npm test
bash test.sh

Adding peers to chain

Edit config file in:

ls ~/.nsd/config/config.toml

TODO

resolver for whois

• FIX set-dag of AlexPlatz... maybe its resets lat lon

msg := types.NewMsgSetDAG(args[0], args[1], cliCtx.GetFromAddress())

• validate DAG valid JSON.
• add push to dag (now its replace)

TODO discuss things

• Branding internet of Buildings
• Purchasing buildings
  • split ownership as CrowdHouse
  • should it be in DAG.. maybe in the chain ?
  • this in DAG OWNERHISTORY/ApplicationIdentifier
    • should go to to ownership chain
  • is it enough to remove notarial office
• TDD approach to buildings with smart contracts
  • automatically recalculate stress tests,
  • automatically recreate energy norms
  • automatically recreate ISO-Norms
• Forking buildings, and paying for DAG to clone
  • should DAG be private
    • maybe a private chain for it ?
  • how enforce payments of for DAG's
  • how to encrypt DAG's
    • DAG can be private
  • is IPFS good place to handle DAG?
    • maybe just use private chain
