1. At present, Internet breeding software includes all people raising cattle, Lenong's home, Aishang raising pig, chicken housekeeper, ugly ckling farm, etc. all people raising cattle, falling in love with raising pig and chicken housekeeper are income oriented apps with little user interaction. They are investment income oriented apps. Ugly ckling farm is an app developed by Shenzhen ugly ckling Innovation Technology Co., Ltd., focusing on user breeding experience, Real time online breeding and offline breeding can be synchronized. Those who have children at home and need to raise their own cks to supplement their families can raise their own cks and eat by themselves through this platform, which is visible in real time, green and pollution-free, and recommended by the wall.

5. Generally speaking, Merkel tree is a way to hash a large number of "chunks" of data. It depends on splitting these data "chunks" into data chunks with smaller units (buckets). Each bucket block contains only a few data "chunks", and then takes each bucket unit data chunk for hashing again to repeat the same process, Until the remaining total number of hashes is only 1: root hash
the most common and simplest form of Merkel tree is binary mekle tree, in which the data block of a bucket unit always contains two adjacent blocks or hashes. Its description is as follows:
decent, bitcoin and Ethereum smart contract are all this structure
6. Merkle trees are the basic components of
blockchain. Theoretically speaking, it is possible to build a blockchain without a Merkel tree. You only need to create a huge block header that directly contains every transaction. However, this will undoubtedly bring scalability challenges. In the long run, only the most powerful computers will be available, To run these untrusted blockchains. It is because of the Merkel tree that Ethereum nodes can be built and run on all computers, laptops, smart phones, and even those IOT devices proced by slock.it. So, how do Merkel trees work, and what value can they provide, now and in the future< First of all, let's talk about some basic knowledge. Generally speaking, Merkel tree is a way to hash a large number of "chunks" of data. It depends on splitting these data "chunks" into data chunks with smaller units (buckets). Each bucket block contains only a few data "chunks", and then takes each bucket unit data chunk for hashing again to repeat the same process, Until the remaining total number of hashes is only 1: root hash.
