+#### getblocktransfertx call
+
+`getblocktransfertx` provides a list of transactions that did some asset
+transfers in a block (either UTXO or NEP5). It gets a block number or hash as
+a single parameter and its output format is similar to `getalltransfertx`
+except for `events` where it doesn't use `address` and `type` fields, but
+rather provides `from` and `to` (meaning that the asset was moved from `from`
+to `to` address).
+
+Example request:
+
+```json
+{ "jsonrpc": "2.0", "id": 5, "method": "getblocktransfertx", "params": [6000003]}

+```
