[英]How to simply implement a mempool for a blockchain in Python?
我目前正在关注一些关于如何使用 python 构建自己的区块链的教程,但我一直在尝试在将它们添加到块之前创建一个内存池(或者,只是在某个地方存储交易),但我意识到我的方法会发送太多请求并使我的服务器运行缓慢。
有什么办法可以实现“内存池”吗? 谢谢!
当您创建 class
class Blockchain:
def __init__(self, public_key, node_id):
# evey blockchain starts with a genesis block
self.__chain=[genesis_block]
# this is called transactions_pool
self.mem_pool=[]
# set other data
def add_transaction(self):
# create a transaction
transaction = Transaction() # whatever args it takes
# verify the transaction
# then add it to mem_pool
self.mem_pool.append(transaction)
def mine_block(self):
copied_transactions = self.mem_pool[:]
# then run the logic to mine block
# after successfully mined the block, set mem_pool as empty
self.mem_pool = []
