Isnt walletexplorer anb blockchain trx info same? I didnt find any difference.if i paste my address in blockchain also i can see all of these same data
there is a difference... walletexplorer combines the information it gets from all transactions...
If you have 3 addresses in the same wallet that were funded with 1 or more unspent outputs, you have this initial situation:
Address A: unspent_output_A_1, unspent_output_A_2
Address B: unspent_output_B_1
Address C: unspent_output_C_1
Now, let's say you make 2 transactions:
transaction 1: uses unspent_output_A_1 and unspent_output_B_1 as input and funds address D en address E
transaction 2: uses unspent_output_A_2 and unspent_output_C_1 as input and funds address F
blockchain will tell you address A and B belong to the same wallet (because unspent outputs funding these addresses were used together in tx 1)
blockchain will tell you address A and C belong to the same wallet (because unspent outputs funding these addresses were used together in tx 2)
walletexplorer will combine this info, and tell you address A, B and C belong to the same wallet because it analyses tx 1 and tx 2 and combines the info.
walletexplorer will also use community info to link addresses to services. If wallet explorer knows address A belongs to service X, it'll indicate that also address B and C belong to service X
