How Inflation Works

Scenario

1. make network
2. make transactions
3. collect all the balances of accounts
4. occur inflation
5. collect all the balances of accounts again
6. compare the collected balances

Preparation

• composed UNSAFE_QUORUM=true network with one validator(tokennet-core:v0.6.2-01fe1e8-20171011195049)
• one horizon(boscoin/tokennet-horizon:tokennet-bc69b65-20171011120646)

INFLATION_FREQUENCY=(60 * 10)

Make Transaction

$ time tokennet-body-maker -apply -verbose -horizon http://192.168.99.110:8080 -concurrency 10 SBQKVXRWIN7DM36PKOH73YFS5EC44H3QUPDULXJJZOSXOU7FB4V62IHZ ./saved/account-balances-100.txt

Collecting Balances

$ PGPASSWORD=bos psql -h 192.168.99.110 -U bos n0 -c 'select accountid, balance from accounts' --pset pager=off -t -F ',' -A > saved/local/inflation/previous-balances-0.txt

Occurring Inflation

$ cd token-infra/src/tokennet-infra/contrib/tokennet-utils/tokennet-inflation
$ go run main.go

Collecting Balances After Inflation

$ PGPASSWORD=bos psql -h 192.168.99.110 -U bos n0 -c 'select accountid, balance from accounts' --pset pager=off -t -F ',' -A > saved/local/inflation/after-balances-0.txt
