1. ETHS铭文

ETHS铭文是以太坊铭文协议Ethscriptions的代币名称。Ethscriptions是一个基于以太坊的铭文协议，允许用户在以太坊主网上刻入不同类型的文件，并将其记录到区块中。ETHS作为Ethscriptions的第一个"概念币"，引起了人们的关注和热议。

以太坊铭文协议Ethscriptions的特点包括：

1. 使用交易调用数据在以太坊上创建和共享数字藏品的新协议[1]。
2. 利用以太坊calldata进行铭文创作，相比使用合约储存更便宜、去中心化，并且能够保证所有有效内容的全球唯一性。
3. 铭文的大小不能超过96KB。

ETHS铭文的铸造方式相对简单，以下是一个示例的铸造步骤：

1. 复制代码：data:，{“p”:“erc-20”，“op”:“mint”，“tick”:“eths”，“id”:“21000以内的任意数字”，“amt”:“1000”}。
2. 将这串代码进行转码，转为16进制。
3. 打开钱包，向自己的地址转入0ETH，并将转码获得的16进制填写。
4. 确认付款，完成代币的铸造。

需要注意的是，ETHS铭文的共识承认只限于编号在21000以内的铭文，而且对于重复被打的编号，只有最先被打的那张ETHS铭文会被承认。

2.批量查询是否被mint

首先安装包：

pip install requests

import hashlib
import jsonimport requests
import threadingdef query_content(content):content1 = "data:," + contentsha256_hash = hashlib.sha256(content1.encode()).hexdigest()url = f"https://eth-script-indexer-eca25c4cf43b.herokuapp.com/api/ethscriptions/exists/{sha256_hash}"try:response = requests.get(url)if response.status_code == 200:result = response.json()if result['result']:# owner = result['ethscription']['current_owner']# creator = result['ethscription']['creator']# creation_timestamp = result['ethscription']['creation_timestamp']## # 转换时间格式为易读形式# creation_timestamp = datetime.datetime.strptime(#     creation_timestamp, "%Y-%m-%dT%H:%M:%S.%fZ")#return -1else:# hex_content = binascii.hexlify(content.encode()).decode()# print(f"\n'{content}'的铭文内容尚未被铭刻。")# print(f"该铭文文本（含data:,）的16进制输出为：{hex_content}")return json.loads(content)["id"]else:print(f"\n获取'{content}'的数据失败，请检查你的输入是否正确。")except requests.exceptions.RequestException as e:print(f"\n发送请求时遇到错误: {e}")def main(name, id_min, id_max):ids = []lock = threading.Lock()def process_content(name, id):content = '{"p":"erc-20","op":"mint","tick":"' + name + '","id":"' + str(number) + '","amt":"1000"}'id = query_content(content)with lock:ids.append(id)# 创建线程列表threads = []for number in range(id_min, id_max):thread = threading.Thread(target=process_content, args=(name, number,))threads.append(thread)thread.start()# 限制线程数量为20if len(threads) >= 20:# 等待前面的线程完成for t in threads:t.join()threads = []# 等待剩余线程完成for thread in threads:thread.join()# 过滤掉值为-1的元素ids = list(filter(lambda x: x != -1, ids))print("未打铭文列表:",ids)if __name__ == '__main__':id_min = int(input("请输入查询id范围下限："))id_max = int(input("请输入查询id范围上限："))name = input("输入铭文名称:")main(name, id_min, id_max)

3. 批量mint

安装web3包

pip install web3 eth_account

import hashlib
import threading
import timefrom web3 import Web3, HTTPProvider
from eth_account import Account
import concurrent.futures
import requests
from eth_account.signers.local import LocalAccount
import binasciidef string_to_hex(string):return '0x' + binascii.hexlify(string.encode()).decode()def query_domain(content):content_ = "data:," + contentsha256_hash = hashlib.sha256(content_.encode()).hexdigest()url = f"https://eth-script-indexer-eca25c4cf43b.herokuapp.com/api/ethscriptions/exists/{sha256_hash}"try:response = requests.get(url)if response.status_code == 200:result = response.json()if result['result']:print(content, "不能被mint")return Falseelse:print(content, "可以mint")return Trueelse:print(f"\n获取'{content}'的数据失败，请检查你的输入是否正确。")except requests.exceptions.RequestException as e:print(f"\n发送请求时遇到错误: {e}")def mint_ethscriptions(w3, wallet, to_address, private_key, content):nonce = w3.eth.get_transaction_count(wallet.address)# 获取当前燃气价格gas_price = w3.eth.gas_pricehex_data_URI = string_to_hex("data:," + content)tx = {'to': to_address,'value': w3.to_wei(0, 'ether'),  # 发送的以太币数量'data': hex_data_URI,'nonce': nonce,'gas': 30000,  # 估算的燃气量'gasPrice': gas_price,'chainId': 1,  # 主网的链ID}# 使用私钥进行交易签名# signed_transaction = w3.eth.account.sign_transaction(tx, private_key)# tx_hash = w3.eth.send_raw_transaction(signed_transaction.rawTransaction)# print(f'Transaction hash: {tx_hash.hex()}')## tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)# print(f'Transaction was confirmed in block {tx_receipt["blockNumber"]}')print('Done')def main(private_key, name, id_min, id_max):w3 = Web3(HTTPProvider("https://rpc.ankr.com/eth"))wallet: LocalAccount = Account.from_key(private_key)count = 0  # 计数器count_lock = threading.Lock()  # 创建锁对象def process_id(name, number):global countcontent = '{"p":"erc-20","op":"mint","tick":"' + name + '","id":"' + str(number) + '","amt":"1000"}'flag = query_domain(content)if flag:with count_lock:if count < 100:mint_ethscriptions(w3, wallet, wallet.address, private_key, content)count += 1with concurrent.futures.ThreadPoolExecutor() as executor:ids = range(id_min, id_max)names = [name] * len(ids)for i in range(0, len(ids), 20):batch_ids = ids[i:i + 20]batch_names = names[i:i + 20]executor.map(process_id, batch_names, batch_ids)time.sleep(10)  # 休息60秒if __name__ == '__main__':private_key = input("请输入钱包私钥：")name = input("请输入要mint的铭文名字：")id_min = int(input("请输入铭文编号下限："))id_max = int(input("请输入铭文编号上限："))main(private_key, name, id_min, id_max)
