How to realize the monitoring of large transaction changes in blockchain

< H2 > there is currently a monitoring block chain for large transactions in major currencies to remind subscribers of their needs. < / H2 >

need to support most major digital currencies

plans that I have thought about by myself

the first solution : through the api query provided by the existing blockchain browsers on the public network, we have found several typical blockchain browsers https://tokenview.com/cn/api-sharp., which provides websocket interface. But it only supports less than 10 currencies
https://blockexplorer.com/api., which seems to support only BTC.
the second option : build a blockchain browser on your local machine, and then get the latest transaction information (Xiaobai has just started to build a blockchain and doesn"t know the feasibility and workload)

the above is what I can think of at present.

ask Daniel to evaluate the feasibility. If you have a better plan, please give us some advice.

it takes a lot of work to build a browser locally.

I am the second type. After all, the API of other websites is unstable, but the cost of the second kind of server is relatively high. I only connected to the mainstream BTC, ETH, EOS

.

Previous: Synchronize problem of ETH nodes

Next: Canvas draws how the scale of the clock rotates individually instead of the whole canvas.
