When subscribing to markets the callback will now receive something that
looks like this:
[ "REMOVED ID1", "REMOVED ID2", ...,
{ "id": "UPDATED ID3", data... },
{ "id": "UPDATED ID4", data... },
...
[ FILL_OPERATION_TYPE_ID, { fill order operation data } ],
[ FILL_OPERATION_TYPE_ID, { fill order operation data } ],
[ FILL_OPERATION_TYPE_ID, { fill order operation data } ],
[ FILL_OPERATION_TYPE_ID, { fill order operation data } ]
]
When ever an order is removed from the order book, its ID will be
included as a string. When an order is modified the new order data is included as
an object. And the operations describing how orders were matched and
what fees are paid will be included as an operation, aka array.
Also added means to unsubscribe from full account data (issue #166)
When subscribing to an account via the get_full_account API it will
start streaming any object relevant to the account that is added,
removed, or modified.
- when updating account there is no need to sign with the active key if
the owner has signed.
- when updating an account the active key is enough to update the
active key.
The blockchain now has a minimal participation requirement that can only
be overridden with checkpoints. Any time participation falls below a
minimal level no new blocks may be added.
Currently it requires 66% participation and tolerates short periods of
time below 66% participation with a maximum of 500 consecutive blocks
missed. For every two blocks produced 1 can be missed with a slack of
999 bias.
This is done to comply with the policy that transactions should be self
describing and not depend upon implied state. This makes things easier
for everyone to understand exactly when a transaction will be invalid
without having to refer to chain state.
1. Implement a TaPoS assert operation predicate that offers full block ID
validation for transactions that want the added security. This is only
required for transactions that are of high value and transfer control of
funds to a newly created identifier and where the witnesses cannot be
trusted.
2. Remove the full block ID from the transaction digest generation.
- added an option (on by default) to prevent a witness from signing two
blocks in a row because this most likely indicates they have been cut
off from the network.
- added an option where a witness will not produce a block if the
witness participation rate is below a configurable threshold (default
to 33%)
