supply

cmd/supply

This is the app that calculates ETH supply for each block and stores it into the db bucket.

Later you can use cmd/rpc to query the database or the daemon itself.

It has the supply calculation as a sync stage, so while you run this app not only does your node get synced, but supply numbers for the new blocks are calculated too.

So you can think of this app as TurboGeth but whith one additional feature.

Usage

> go run ./cmd/supply --datadir <path-to-your-tg-datadir> --private.api.addr=localhost:8787

The you wait for the sync to complete (it will include ETH supply calculation).

DataDir

You can point this app to the existing tg datadir and it will use it just fine. It is compatible with v2020.09.04 and v2020.09.03 versions of turbo-geth.

Performance

On my machine ETH supply stage takes about 4 hours.

You should see this log message.

INFO [09-29|09:42:09.093] ETH supply calculation... DONE. use `tg_getSupply` to get values

Requesting the supply via RPC

If you still have the ./cmd/supply node running, you can run the RPC daemon too.

> go run ./cmd/rpc --private.api.addr=localhost:8787 --http.api=eth,debug,net,tg

Make sure that --private.api.addr value matches for both cmd/supply and cmd/rpc.

Note that tg namespace is added to http.api parameter!

Then you can use curl to request supply for any block.

For genesis:

curl --request POST \
  --url http://localhost:8545/ \
  --header 'content-type: application/json' \
  --data '{
	"jsonrpc": "2.0",
	"id": 88888,
	"method": "tg_getSupply",
	"params": [0]
}'

For the latest block:

curl --request POST \
  --url http://localhost:8545/ \
  --header 'content-type: application/json' \
  --data '{
	"jsonrpc": "2.0",
	"id": 88888,
	"method": "tg_getSupply",
	"params": ["latest"]
}'

For any block number:

curl --request POST \
  --url http://localhost:8545/ \
  --header 'content-type: application/json' \
  --data '{
	"jsonrpc": "2.0",
	"id": 88888,
	"method": "tg_getSupply",
	"params": [10000]
}'

You will receive a response like that

{
  "jsonrpc": "2.0",
  "id": 88888,
  "result": {
    "block_number": 0,
    "supply": "72009990499480000000000000"
  }
}
