GetBlock

Task description

Develop a service which provide to get top 5 addresses by Activity metric for 100 last blocks.
Metric increases per each transaction between addresses.

Example

Alice has sent 100 USDC Alice received 5 DAI

Alice's Activity metric equal 2

Setting up

clone repo

  git clone git@github.com:ur-os/getBockStd.git  
  cd getBockStd

for the next step you need to have an installed docker https://docs.docker.com/engine/install/ubuntu/ (if you using ubuntu)

    sudo docker build -t get-block .

This service have a configs. So next you can config service in .env file, or set all env's on docker run

With config by file:

sudo docker run --rm -it -p 127.0.0.1:8080:8080 --env-file .env.example get-block:latest

By console (don't forget change ports in -p if different):

sudo docker run --rm -it -p 127.0.0.1:8080:8080 -e GET_BLOCK_ENDPOINT=go.getblock.io -e GET_BLOCK_PORT=8080 get-block:latest

Your service ready to serve.

Try to get a mEtRiC (for example):

curl http://localhost:8080/getTopFiveUserActivity

#output: {"status":"ok","code":200,"payload":["0x83c41363cbee0081dab75cb841fa24f3db46627e = 533","0xf89d7b9c864f589bbf53a82105107622b35eaa40 = 124","0x58edf78281334335effa23101bbe3371b6a36a51 = 66","0x28c6c06298d514db089934071355e5743bf21d60 = 62","0x75e89d5979e4f6fba9f97c104c2f0afb3f1dcb88 = 61"]}

Configs

• GET_BLOCK_API_KEY - can be passed. if your rpc node use path param for api key, put it here (example: 1234567890abcde000000000000000000)
• GET_BLOCK_DEPTH - by default it sets 100. Indicates how many blocks you will use for metric
• GET_BLOCK_ENDPOINT - necessary to be set. Hostname of your node (example : go.getblock.io)
• GET_BLOCK_PORT - by default sets 8080. Port for your application
• GET_BLOCK_PULLING_STEP - by default sets 50. Degree of parallel processing. For 50 - 100 block in 2 batches
• GET_BLOCK_TIMEOUT - by default 300s. How long you can await metric response
• GET_BLOCK_RPS_LIMIT - by default 50ms. Delay between 2 threads request node

you can find example of .env in .env.example
