Data is permanently stored in the Bitcoin Bitcoin network through blocks (Blocks). Each block contains information on all recent transactions, a Nonce (nonce) and the hash of the previous block. When the SHA-256 hash of the entire block is lower than the current target, it is marked as "resolved" (published and verified by multiple nodes). Usually one hash is hard to reach the target, so the Nonce has to be increased and the block has to be re-hash millions of times to reach the target.
Bitcoin Bitcoin transactions are broadcast into the network by remitters, and all mining nodes (clients) collect Bitcoin and add it to the block they are working on. If the transaction volume is large and exceeds the average transaction volume, the network will deduct a small transaction fee.
The first transaction in each block is special: it creates new bitcoins for the first person to mine a valid block. Other nodes ( Bitcoin clients ) will only accept the block if the transaction amount is correct. The number of bitcoins produced per block is 50, halved every 210,000 blocks (approximately 4 years).
The network attempts to create 6 blocks per hour. Every 2016 blocks (approximately two weeks), all Bitcoin clients compare this target to the actual number of blocks created, and modify the difficulty percentage of block mining to maintain this target.
The client considers the "longest" blockchain to be valid. The "length" of the entire blockchain refers to the chain with the most additive difficulty, not the chain with the most blocks. This prevents someone from forging and creating lots of low-difficulty blocks, tricking the network into accepting them as the "longest" chain.
How many blocks have been mined so far?

What is the maximum number of blocks?
There is no maximum number. Blocks are continuously added to the end of the blockchain every 10 minutes
Even when all 21 million bitcoins have been mined, the blocks will still keep increasing?
Yes. Blocks are used to prove that a transaction existed at a specific time. Transactions still happen after all bitcoins have been mined. So as long as someone trades bitcoin, the block will still be created.
How long does it take to collect a valid block?
No one can tell exactly. There is a mining calculator that will tell you how long it might take.
如果我计算某个区块的进度增加了 1% 意味着什么?
没有进度增加 1% 的说法。每次运算并不会增加进度。计算 24 小时后您获得比特币的几率和您刚开始计算时是相等的。
这和您同时旋转 37 个硬币并使它们都正面朝上一样。每次您尝试，您成功的机会是相同的。
