v1.7.0

Changelog

Uplifted Substrate base version to polkadot-v0.9.43.

Client

Block height manipulation

Developers can forward blocks and revert blocks to requested block heights.

Forward blocks via RPC

Forwarding blocks to requested block height by calling engine_forwardBlocksTo.

$ curl http://127.0.0.1:9944 -H "Content-Type:application/json;charset=utf-8" -d   '{
     "jsonrpc":"2.0",
      "id":1,
      "method":"engine_forwardBlocksTo",
      "params": [120]  
    }'

Params

• Height
  height denotes an integral value that signifies the desired block height towards which the user intends to progress. If the value is lower than current height, RPC returns an error.

Revert blocks via RPC

Reverting blocks to requested block height by calling engine_revertBlocksTo.

Note that reverting finalized blocks only works when node is launched with archive mode --state-pruning archive (or --pruning archive) since reverting blocks requires past blocks' states.
When blocks' states are pruned, RPC won't revert finalized blocks.

$ curl http://127.0.0.1:9944 -H "Content-Type:application/json;charset=utf-8" -d   '{
     "jsonrpc":"2.0",
      "id":1,
      "method":"engine_revertBlocksTo",
      "params": [50]
    }'

Params

• Height
  height denotes an integral value that represents the desired block height which the user intends to revert to. If the value is higher than current height, RPC returns an error.

Runtimes

Account Balance manipulation

For local development purpose, developers can manipulate any users' account balance via RPC without requiring their accounts' signatures and transaction cost to pay.

Get Account Balance

Getting users' account balance by balance_getAccount method.

curl http://127.0.0.1:9944 -H "Content-Type:application/json;charset=utf-8" -d   '{
     "jsonrpc":"2.0",
      "id":1,
      "method":"balance_getAccount",
      "params": ["5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY", null]
    }'

Params

• Account ID
  account_id is AccountID whose balance information you would like to check.

Set Free Balance

Free balance is amount of unreserved token owner can freely spend. balance_setFreeBalance alters the amount of free token a specified account has.

curl http://127.0.0.1:9944 -H "Content-Type:application/json;charset=utf-8" -d   '{
     "jsonrpc":"2.0",
      "id":1,
      "method":"balance_setFreeBalance",
      "params": ["5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY", 120000000000000000000, null]
    }'

Params

• Account ID
  account_id is AccountID whose balance you would like to modify.

• Free Balance
  free_balance is new Balance value you would like to set to accounts.

v1.6.0

Changelog

Client

• Delayed finalize #61

By default, either manual or instant seal does not result in block finalization unless the engine_finalizeBlock RPC is executed. However, it is possible to configure the finalization of sealed blocks to occur after a certain amount of time by setting the --finalize-delay-sec option to a specific value, which specifies the number of seconds to delay before finalizing the blocks.

./target/release/swanky-node --finalize-delay-sec 5

In the above example, a setting of 5 seconds would result in the blocks being finalized five seconds after being sealed. In contrast, setting the value to 0 would lead to instant finalization, with the blocks being finalized immediately upon being sealed.
