新的交易模板可以按需添加。用不了几天，就会有大量 GPU 算力接受并处理它。网络支持会早在有足够多客户端懂得接收和解读新交易之前就完善。
时间戳哈希现在其实已经能做：
txin: 0.01
txout: 0.00 <appid, hash> OP_CHECKSIG
fee: 0.01
如果真有像 BitDNS 这样的实际应用准备开始往链里插哈希，我们随时可以加一个专门的时间戳交易模板。
我喜欢 Hal Finney 的用户友好时间戳想法。把文件的哈希转成比特币地址，往它发 0.01：
引用自 Hal（2010 年 12 月 5 日 11:43:56 PM）（https://bitcointalk.org/index.php?topic=2077.msg27173#msg27173）：我想到了个简单办法实现上面说的时间戳概念。对你想加时间戳的文件跑 sha1sum。把结果转成比特币地址，比如用 http://blockexplorer.com/q/hashtoaddress 。然后往那个地址打一小笔款。
这笔钱会永远丢失，因为没法再花出去，但时间戳比特币地址会作为文件存在过的记录留在区块链里。
我知道这可以说不是比特币分布式数据库的好用法，但没人能阻止人们这么干，所以我们得知道它可能发生。

New transaction templates can be added as needed. Within a few days, there will be plenty of GPU power that accepts and works on it. Network support will be thorough long before there'll be enough clients who understand how to receive and interpret the new transaction.
Timestamp hashes are still already possible:
txin: 0.01
txout: 0.00 <appid, hash> OP_CHECKSIG
fee: 0.01
If there's an actual application like BitDNS getting ready to actually start inserting hashes, we can always add a specific transaction template for timestamps.
I like Hal Finney's idea for user-friendly timestamping. Convert the hash of a file to a bitcoin address and send 0.01 to it:
Quote from: Hal on December 05, 2010, 11:43:56 PM（https://bitcointalk.org/index.php?topic=2077.msg27173#msg27173）I thought of a simple way to implement the timestamp concept I mentioned above. Run sha1sum on the file you want to timestamp. Convert the result to a Bitcoin address, such as via http://blockexplorer.com/q/hashtoaddress . Then send a small payment to that address.
The money will be lost forever, as there is no way to spend it further, but the timestamp Bitcoin address will remain in the block chain as a record of the file's existence.
I understand that this is arguably not a good use of the Bitcoin distributed database, but nothing stops people from doing this so we should be aware that it may be done.
