파이선 beem 모듈을 이용해서 블러트 계정의 트랜잭션(transaction) 이력을 조회할 수 있습니다. Account 객체의 get_history_reverse()를 사용합니다.

from beem import Blurt
from beem.account import Account

blurt_node = ["https://rpc.blurt.world"]
blurt = Blurt(node=blurt_node)

account = Account('joviansummer', blockchain_instance=blurt)

# 계정의 최근 트랜잭션을 가져오기 위한 제네레이터
r_hist = account.history_reverse(raw_output=True)

# 최근 5개의 트랜잭션 출력
for i in range(5):
    hist_item = next(r_hist)
    print(hist_item)

위의 예시에서 출력 결과는 딕셔너리(dict) 형식이며, 아래의 예시와 같은 형태로 가져옵니다.

[1487, {'trx_id': '0000000000000000000000000000000000000000', 'block': 15167787, 'trx_in_block': 4294967295, 'op_in_trx': 0, 'virtual_op': 1, 'timestamp': '2021-12-23T05:37:27', 'op': {'type': 'producer_reward_operation', 'value': {'producer': 'joviansummer', 'vesting_shares': {'amount': '1567350', 'precision': 6, 'nai': '@@000000037'}}}}]

필요한 항목을 가져와서 활용하면 됩니다.

# 블럭 번호 출력
print(hist_item[1]['block'])

# operation 식별자 출력
print(hist_item[1]['op']['type'])

GentBG will continue to burn STEEM, with reduced posting frequency

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/gentbg-will-continue-to-burn-steem-with-reduced-posting-frequency Hello, this is @joviansummer(witness: @jswit). GentBG project has been going on for a few month. For more information about this project, check the following posts: GentBG - a new experiment to burn STEEM GentBG - why bother to burn STEEM? I'm making some changes to GentBG project's configurations. Unfortunately, this project haven't gained enough traction, but considering that burning STEEM is necessary(because STEEM supply has no limit) I'm going to continue this project as long as possible. The problem is that AI technology is not cheap. So I'm planning to change configuration to reduce the number of images per week from 2 to 1. Also, I don't think I can guarantee that image will be available every week. There might be a week without image. The current batch of images will be exhausted on September 18th. Configur...

GentBG - why bother to burn STEEM?

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/gentbg-why-bother-to-burn-steem GentBG - a new experiment to burn STEEM Hello, this is @joviansummer(witness: @jswit). I'd like to briefly explain why I bothered to start @gentbg experiment. Unlike bitcoin, STEEM has no supply limit. As long as STEEM exists, newly minted STEEM will be added to total supply. If we can't maintain corresponding demand or reduce supply, downward pressure on STEEM price can be a big challenge. @gentbg project is an experiment to reduce STEEM supply by burning. @gentbg will burn liquid author reward and delegate SP reward to @jsup to get amplified upvotes. The main purpose is to create a perpetual STEEM burning loop. I added a bit of fun factor via AI-generated images, to incentivize giving upvotes to @gentbg's posts. If you have some spare voting power, you can contribute to burning STEEM by giving upvotes to @gentbg's posts. Initial run of this experiment wil...

Making a table format on Discord

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/making-a-table-format-on-discord Hello, this is @joviansummer. My code revision of the automated missed-block reporter for witness Discord channel continues. After implementing mentioning(pinging) capability , I'm trying to convert reporting format to tabular form. It was requested by witness @steemchiller). On Steemit, creating a table is easy thanks to markdown table support. On Discord, unfortunately, table is not supported. Discord only supports a limited subset of markdown and table is not available. Thus, it seems the only way to make something similar is to use code block. In code block, text alignment possible because every character occupies the same width. You can see the difference from the screenshot below: Now, I need to make sure each field occupies pre-determined length. Thankfully, python provides a really useful capability called f-string. Here is an example. name = '@joviansumm...
