三、研究院前沿探索

1. 区块链支付结算

上海金融与区块链研究院在区块链支付结算领域进行了深入探索。通过研发基于区块链的支付系统，实现了跨境支付、跨境汇款等场景的高效、低成本处理。以下是一个简单的区块链支付结算示例代码：

# 区块链支付结算示例代码
class Transaction:
    def __init__(self, sender, receiver, amount):
        self.sender = sender
        self.receiver = receiver
        self.amount = amount

class Block:
    def __init__(self, index, transactions, timestamp, previous_hash):
        self.index = index
        self.transactions = transactions
        self.timestamp = timestamp
        self.previous_hash = previous_hash
        self.hash = self.compute_hash()

    def compute_hash(self):
        block_string = f"{self.index}{self.transactions}{self.timestamp}{self.previous_hash}"
        return hashlib.sha256(block_string.encode()).hexdigest()

class Blockchain:
    def __init__(self):
        self.unconfirmed_transactions = []
        self.chain = []
        self.create_genesis_block()

    def create_genesis_block(self):
        genesis_block = Block(0, [], datetime.now(), "0")
        genesis_block.hash = genesis_block.compute_hash()
        self.chain.append(genesis_block)

    def add_new_transaction(self, transaction):
        self.unconfirmed_transactions.append(transaction)

    def mine(self):
        if not self.unconfirmed_transactions:
            return False
        last_block = self.chain[-1]
        new_block = Block(index=last_block.index + 1,
                          transactions=self.unconfirmed_transactions,
                          timestamp=datetime.now(),
                          previous_hash=last_block.hash)
        new_block.hash = new_block.compute_hash()
        self.chain.append(new_block)
        self.unconfirmed_transactions = []
        return new_block

# 创建区块链实例
blockchain = Blockchain()

# 添加交易
blockchain.add_new_transaction(Transaction("Alice", "Bob", 50))

# 矿工挖矿
blockchain.mine()

2. 资产交易

在资产交易领域，上海金融与区块链研究院通过区块链技术实现了资产登记、交易、清算等环节的自动化处理。以下是一个基于区块链的资产交易示例代码：

# 基于区块链的资产交易示例代码

        self.owner = owner
        self.value = value

class AssetTransaction:
    def __init__(self, sender, receiver, asset, amount):
        self.sender = sender
        self.receiver = receiver
        self.asset = asset
        self.amount = amount

class AssetBlockchain:
    def __init__(self):
        self.unconfirmed_transactions = []
        self.chain = []
        self.create_genesis_block()

    def create_genesis_block(self):
        genesis_block = Block(0, [], datetime.now(), "0")
        genesis_block.hash = genesis_block.compute_hash()
        self.chain.append(genesis_block)

    def add_new_transaction(self, transaction):
        self.unconfirmed_transactions.append(transaction)

    def mine(self):
        if not self.unconfirmed_transactions:
            return False
        last_block = self.chain[-1]
        new_block = Block(index=last_block.index + 1,
                          transactions=self.unconfirmed_transactions,
                          timestamp=datetime.now(),
                          previous_hash=last_block.hash)
        new_block.hash = new_block.compute_hash()
        self.chain.append(new_block)
        self.unconfirmed_transactions = []
        return new_block

# 创建资产区块链实例
asset_blockchain = AssetBlockchain()

# 创建资产
asset = Asset("Alice", 100)

# 创建交易

        last_block = self.chain[-1]
        new_block = Block(index=last_block.index + 1,
                          transactions=self.unconfirmed_transactions,
                          timestamp=datetime.now(),
                          previous_hash=last_block.hash)
        new_block.hash = new_block.compute_hash()
        self.chain.append(new_block)
        self.unconfirmed_transactions = []
        return new_block

# 创建供应链金融区块链实例

        self.total_supply = total_supply
        self.balance = {}

    def issue(self, address, amount):
        if amount <= self.total_supply:
            self.balance[address] = self.balance.get(address, 0) + amount
            return True
        return False

    def transfer(self, from_address, to_address, amount):
        if self.balance.get(from_address, 0) >= amount:
            self.balance[from_address] -= amount
            self.balance[to_address] = self.balance.get(to_address, 0) + amount
            return True
        return False

# 创建数字货币实例
digital_currency = DigitalCurrency("DCoin", 1000000)

# 发行数字货币
digital_currency.issue("Alice", 5000)

# 转账
digital_currency.transfer("Alice", "Bob", 1000)
