#### Versions 4.x.x
|
||||
**Version 4.x.x**
|
||||
|
||||
As part of the changes in the BigchainDB 2.0 server, some endpoints were
|
||||
modified. In order to be consistent with them, the JS driver does not have
|
||||
anymore the `pollStatusAndFetchTransaction()` method as there are three
|
||||
different ways of posting a transaction:
|
||||
|
||||
- `async` using the `postTransaction`: the response will return immediately and not wait to see if the transaction is valid.
|
||||
- `sync` using the `postTransactionSync`: the response will return after the transaction is validated.
|
||||
- `commit` using the `postTransactionCommit`: the response will return after the transaction is committed to a block.
|
||||
|
||||
By default in the docs we will use the `postTransactionCommit` as is way of
|
||||
being sure that the transaction is validated and commited to a block, so
|
||||
there will not be any issue if you try to do any other action with the asset immediately.
