The difference between bitcoin signature and Ethereum signature
Publish: 2021-05-08 19:20:07
1. BTC: bitcoin LTC: lightcoin eth: Ethereum, Ethereum etc: Ethereum classic
2.
The user groups of Ethernet and bitcoin are different
3. Bitcoin and Ethereum are both digital currencies. Bitcoin ranks first in market value, followed by Ethereum. After registering with the bitnet exchange, you can invest in them.
4. The digital signature of bitcoin is an anti-counterfeiting string generated only by the transferor of bitcoin transfer. By verifying the digital string, on the one hand, it proves that the transaction is initiated by the transferor, on the other hand, it proves that the transaction information has not been changed in the transmission
digital signature shortens transaction information to a fixed length string through digital digest technology. For example, when Niuniu initiates a bitcoin transfer, it needs to first digest the transaction into a string, and then encrypt the digest with its own private key to form a digital signature. After the completion, Niuniu needs to broadcast the original (transaction information) and digital signature to the miner, and the miner uses Niuniu's public key for verification. If the verification is successful, it means that the transaction is indeed sent by Niuniu, and the information has not been changed
at the same time, the private key encrypted by digital signature is inconsistent with the public key decrypted by digital signature, so asymmetric encryption technology is adopted. It looks so complicated. In fact, you only need to input the private key to complete the transfer instantly!

5. The digital signature in bitcoin is generated by the initiator in the transaction. In order to ensure that this transaction is initiated by this person, and the data is not tampered with ring transmission. Digital signature is simply a complete transaction information, compressed into a fixed format string by digital digest technology, and then generated a private key by asymmetric encryption technology. The complete transaction information and digital signature are sent to the miner. The miner decrypts the digital signature with the public key of the transaction initiator. If the decryption is successful, the transaction data will be written into the block.
6. You can open the Matcha app to see that now Ethernet is the second highest cryptocurrency in market value, second only to bitcoin.
7. blockchain colloquialism:
mahjong is the earliest application of blockchain in China:
the idea that a wants to play mahjong is equivalent to creating a block:
a calls to inform B, C and D, which means "decentralization & quot; Point to point transmission of
ABCD has formed a consensus that the touch action is "mining", and four people are "miners"
mahjong is a hash value. The Hu card is to hit the correct hash value and get the corresponding chip reward, which is called bitcoin
each of the four recorded the first round of the game. In the whole blockchain, this is only one node. If 20 mahjong games were played that day, that is, 20 nodes (blocks), and 20 blocks were connected together to form a complete ledger, that is blockchain< According to historical records, China is the world's earliest application group in blockchain, so you can be proud to say that China is more than 1000 years ahead of the world in blockchain application
it's powerful. Our country is [strong] [strong] [strong]

8. 1) From the perspective of consensus mechanism, bed, BTC and eth are all POW consensus mechanisms
2) in terms of algorithm, the core algorithm sha256 adopted by bed and BTC has the same value attributes, but bed has established a new economic model through new technology development; Eth uses ethash algorithm
3) from the perspective of mining cost: BTC mining is becoming more and more difficult and has become an arena for mining equipment. At present, the latest 110t ant S19 Pro mining machine has adopted the latest 7Nm chip, and the price of the machine is nearly 20000 yuan. Some low computing power machines, such as the former king ant S9, can only be eliminated, resulting in a huge waste of resources; Eth uses graphics card GPU to mine, and the cost is also quite high; And bed can dig directly with the existing bitcoin miner or the obsolete bitcoin miner with low computing power, so the cost of miner is very low and the waste of resources is reced
4) from the perspective of total amount and upgrade space: the total amount of BTC is 21 million, and the current price is about ￥ 76000; The total amount of eth will reach 113 million, and the current price is about 2500 yuan; The total amount of bed and BTC is 21 million, and there is a huge space for upgrading.

9. They are both encrypted virtual digital currencies. The difference is that bitcoin was born early, has a large audience and is highly accepted (Dell and Microsoft both accept bitcoin payment). It is the representative and originator of cryptocurrency, and has a high market value. Bitcoin is also a small-scale social experience, Ethereum is the second generation of digital currency, and lutcoin is the follow-up currency.
10. Bitcoin is not only the main body of ether coin, but also the originator of digital currency. The relationship between ether coin and bitcoin is just like you cut a piece with green color from a sweet potato and then bury it. Later, it takes root and grows into a sweet potato. The original is still the original, but part of its body evolves into digital currency, just with different names
