1. You can choose to trade in the digital currency exchange. At present, the mainstream digital currency exchanges in the market are coin security, fire currency and bitnet.
2.
transactions.forEach(function(tx){
vartxInfo=web3.eth.getTransaction(tx.transactionHash);
/ / at this time, the transaction information txinfo can be stored in the database
})< br />});
If you want to query the transaction records on the main network, you can use Etherscan. However, if you build your own private chain, how should you query the transaction records
the answer is that you need to listen to the logs on the chain, save them in the database, and then query them in the database. For example:
< pre t = "code" L = "Java" > varaddr = & quot& quot;< br />varfilter=web3.eth.filter({fromB lock:0 ,toBlock:' latest', address:addr });< br />filter.get(function(err,transactions){transactions.forEach(function(tx){
vartxInfo=web3.eth.getTransaction(tx.transactionHash);
/ / at this time, the transaction information txinfo can be stored in the database
})< br />});
Web3. Eth. Filter() is used to monitor the log on the chain, and Web3. Eth. Gettransaction() is used to extract the information of the specified transaction. Once the transaction information is obtained, it can be stored in the database for query

3. With bitpie wallet, this is the largest bitcoin wallet in China. It can buy and sell bitcoin with one click, which is much more convenient than the exchange.
4. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.
5. At present, Ethereum is still good. If you want to check real-time data, you can use two kinds of Ethereum, namely, fire coin and cell ETF. You go to see celletf.pro
6. Just focus:
you can't retrieve your assets through Ethereum block query
think too much
if you want to check the real estate,
you can go to the real estate transaction registration center.

7. Search Ethereum blockchain browser or bitcoin blockchain browser. If it is based on other chains, search other browsers to view
8. Many people are optimistic about the decentralized exchange. The private key is in their own hands and they enjoy complete control over the user's assets. However, e to the congestion of Ethereum's public chain, the trading experience of the decentralized exchange on Ethereum is not very good and slow. At present, the most promising is the X protocol, but if the problem of Ethereum is not solved, its application problems can not be started at all
in comparison, the decentralized exchange based on EOS is much better, because its TPS is fast enough to handle the decentralized application at the present stage, and its speed is much better than that on Ethereum. Whaleex, in particular, is very smooth in use, with fast transactions. It is not inferior to those centralized exchanges. Among all decentralized exchanges, whaleex is excellent
therefore, I think the decentralized exchange on EOS may break out faster than that on Ethereum, especially the whale exchange, which will be a dark horse. The smart contract of their home is also the only one that has passed the slow fog security audit. The security is particularly high and the use is assured.

9. Yesterday, Ethereum forgot the congestion and delayed more than 50000 transactions. Wait patiently. If not, please contact the trading platform.
10. You can check the market of Ethereum on non trumpet, but you can't trade it. If you want to invest, you can go to the digital currency exchange. At present, all the mainstream digital currency transactions in the market are coin security, fire coin network, bitnet, etc.
