Justswap, the TRON version of Uniswap platform, is online. Currently, there are TRX, JST, USDT and other erc-20 tokens. However, there are a large number of "counterfeit coins" among them, and the trademark names of many projects have been "squashed".

The transfer of the giant whale address worth more than 243 million US dollars is actually an internal operation of Coinbase
The Beijing Chainsmap monitoring system found that the transfer of 19,721.59 BTC (worth more than 243 million US dollars), which was hotly discussed in the industry at 2:16 a.m. Beijing time on August 18, was actually an internal operation of Coinbase. This huge amount of bitcoin was transferred from the address starting with 12BZD75sb to the address starting with 1FRKZeipb, and then most of it was split into 100 UTXOs of the same amount. This is also a common operation of Coinbase, and there is no need to over-interpret it.
If the participation rate of Medalla verifiers on the Ethereum 2.0 testnet fails to pick up, it will consider redeploying the deposit contract
Prysmatic Labs, the execution team of the Ethereum 2.0 client, released an analysis report on the current clock bug of the testnet Medalla. Ethereum developer Ben Edgington concluded that within a few minutes on the evening of August 14, the number of active verifiers dropped from 22,000 to about 5,000, and about 80% of the verifiers in the network disappeared. The cause of the incident was a problem with clock sync . The Prysm client is configured to use Cloudflare's Roughtime to calculate time.
So far, the network is gradually recovering, and the new versions of Prysm and Lighthouse are continuing to build the beacon chain. In the future, Teku will continue to be optimized to reduce the resources required for synchronization. However, there is no consensus failure between clients. When the network is restored, all clients can reach a consensus on the state of the chain head. The beacon chain will not fail fundamentally, and no hard fork will be required.

Ethereum Classic (ETC) has suffered two cyber attacks recently. Some major crypto exchanges such as Huobi, Kraken, OKEx, OKCoin, and Poloniex are closely monitoring the ETC network and are holding a wait-and-see attitude towards delisting ETC tokens. OKEx stated that if the ETC community fails to formulate protective measures to prevent further attacks, ETC will be forcibly delisted; Binance founder Zhao Changpeng stated that Binance will first consider the number of users of the relevant token network before making a decision to list or delist And so on, and ETC still has a very large user base.

V God: Client verification is critical for all related work
On August 17, V God published an article "Philosophy of Blockchain Verification" on his personal website. First, if accepting the legitimacy of social coordination, and accepting the legitimacy of indirect verification involving a "1-of-N" trust model (i.e. assuming that there is an honest person somewhere in the network, this is not the same as assuming that a particular Participants are honest, such as Infura), then we can create a more scalable blockchain.
Second, client-side validation is critical for all related work. Only a few people run nodes, while everyone else truly trusts their network and thinks it can be easily taken over by special interests. To avoid situations like this, it is not necessary to have everyone verify everything. The system allows each individual block to be validated, so users only validate blocks when others sound the alarm, which is perfectly reasonable and achieves the same effect.
Third, if the normative definition includes time, it will improve the chain's ability to reject 51% attacks. For example, the user is required to log in within a certain time limit. If the time for not replying exceeds the time limit, necessary measures will be taken to increase the cost of the attack. The initiative can even refuse to restore the chain of completed code blocks, thereby protecting immutability and even preventing censorship.
