그러나 나는 심지어 제 2의 시간 생각을 blockchain 다운로드 9.</p> <p>블록의 거래를 읽을 수 없다, 내가 파이썬 librairy 'bitcoinrpc'와 비트 코인 코어를 사용하여 blochain 놀고 있었는데 특정 블록 거래

Question

을 읽을 수 없습니다 광산은 다른 데이터 디렉토리를 가리키는 bitcoin-core의 두 번째 설치에 문제가 있었고 여전히 블록 9를 읽을 수 없습니다.

이 문제를 재현 할 수 있습니까? 왜 그런가?

스크립트를 읽고 표시 블록 7, 8, 9, 10 :

from bitcoinrpc.authproxy import AuthServiceProxy 
import traceback 

RPC_ADDRESS="127.0.0.1:8332" 
RPC_USER="u" 
RPC_PASSWORD="p" 

def display_block_info(rpc, block_number): 
    print "-------- block {} start -------".format(block_number) 
    block_hash = rpc.getblockhash(block_number) 
    print "Block hash : " + block_hash 
    block = rpc.getblock(block_hash) 
    for tx in block[u'tx']: 
     print "processing transaction " + tx 
     print rpc.getrawtransaction(tx, True) 
    print "-------- block {} end -------".format(block_number) 
    print "" 

if __name__ == "__main__": 
    rpc = AuthServiceProxy("http://%s:%s@%s"%(RPC_USER, RPC_PASSWORD, RPC_ADDRESS)) 
    block_numbers = [7, 8, 9, 10] 
    for block_number in block_numbers: 
     try: 
      display_block_info(rpc, block_number) 
     except Exception as e: 
      traceback.print_exc() 
      print "-------- block {} end -------".format(block_number) 
      print "" 

결과 : 당신이 거래 '0437cd7f8525ceed2324359c2d0ba26006d92d856a9c20fa0241106ee5a597c9'을 볼 수 있듯이

사용하여 읽을 수 없습니다 rpc.getrawtransaction(tx, True)

Answer 1

없이 bitcoind을 실행하고 있기 때문에 문제가 발생할 가능성이 큽니다.명령 행 플래그. 그것 없이는 bitcoind은 사용되지 않은 트랜잭션 출력과 트랜잭션을 추적합니다. 처음 몇 개의 블록이 작동하는 이유는 이들이 단지 사용되지 않은 기원 출력 즉, 새로 생성 된 동전만을 포함하기 때문입니다. 당신이 파싱에 실패한 거래는 Satoshi에서 Hal Finney까지의 첫 번째 거래입니다.이 트랜잭션은 더 이상 색인에 쓰이지 않습니다.

시도 중 -txindex 이상 사용 getblock(block_hash, 0) 실행하면 진수 직렬화 블록을 얻을하고 대신 모든 단일 트랜잭션을 검색 할 수 bitcoind를 사용하는 (예를 들어, bitcoinlib에) 로컬로 구문 분석합니다. 이런 식으로 훨씬 더 빠를 것입니다.
