On December 1, Ethereum developer Tim Beiko published an article explaining how the integration of Eth1 and Eth2 could affect the Ethereum application layer. 1. Block structure: The blocks in the tag chain have merged execution loads equal to the credentials blocks of the current operation. ExecutionPayloads is an interactive site with Ethereum. 2. Mining and Uncle Blocks: Several fields in the header of the Proof-of-Work block are obsolete and set to approximately 0. Because the proofs of stakes do not generate the uncle blocks like the proof of operation, the names of the uncle blocks are empty, and the hash of the names becomes an RLP encoded hash of the empty names. 3. Replace BLOCKHASH and DIFFICULTY opcodes: BLOCKHASH opcodes have low pseudo-randomness, DIFFICULTY opcodes have been modified and renamed to RANDOM. 4.Average block design time: about 13 seconds now, reduced to 12 seconds after sharing 5. Security header and final block: Rebuildable as proof of work. The final block is approved by more than 2/3 of the certificates. To create a collision, the attacker must break at least 1/3 of the total contract (currently around 2.5 million ETH, worth up to US $ 10 billion). A security header block is a block that must be placed in a specific directory in a network instance. Assuming the network latency is less than 4 seconds, the security header will not be an orphan block unless most validator nodes are fair and have no objection to the fork option. .

"Blockchain" technology has blessed the Changsha Wangcheng "Unlicensed City" online platform to try to operate.
On December 1, Changsha Wangqing City's "License-Free City" platform was put online. Wangcheng District Leifeng Government Department Store 9 departments have 127 government products, 10 kinds of certificates are "face scan" or "code scan" (certificate), citizens' tests should not contain physical data, they can scan their face to clear the job. . Wangcheng District "Unlicensed City" is the state's first "Unlicensed City" project with the federal emergency response system. It is the first state to introduce a “blockchain” for unlicensed urban electricity certifications. The technology-based 'tech' program is also the state's first 'blockchain' technology to be used for certain government and public services (Sina Finance).
