1) The block element can contain both the block element and the inline element, but the inline element may contain only the inline element.

Storing extra data
Storing additional data on a block chain refers to data that exists on the block chain but has no impact on the transaction, and there are two main ways to store additional data: Op_return and Multi-signatures. Op_return
A new feature was introduced in the Bitcoin protocol in 2013, which was to create a transaction called Op_return that could embed 40 bytes of data (currently 80 bytes).
Recently the latest Linux kernel has been released to LINUX-3.19-RC6, according to Linus's release note, about once again after a RC7 version can be formally released. The biggest change to the Linux 3.19 kernel at the block level is the addition of a multi-queue block layer to better support devices like NVMe that support the multi-queue mechanism. The so-called multi-queue mechanism is that in the case of
What does Bumong do?
Bumong is a digital asset network built using block-chain technology, where any asset-owning institution/individual can distribute its digital assets (such as digital gold, credits, game equipment, etc.) on the network, and the assets can be freely convertible and circulated in the network.

Personally, I used to know that the so-called mining is about to find a random number, so that the hash value of the block is less than a certain number, but what is the specific. I don't know... And, of course, not only that, many other concepts like the structure of blocks, the s
