Platform Parameters
These are parameters to configure IBAX. They are applicable to the blockchain network and all ecosystems within it.
Location to store platform parameters
Platform parameters are stored in the system_parameters table.
This table is located in the first (default) ecosystem created on the blockchain network.
Change of platform parameters
Change of platform parameters can only be made through voting. You can only use the UpdateSysParam contract to change any platform parameter, which is managed by definitions in the legal system of the platform.

Depreciated parameters:
Details of platform parameters
block_reward
The number of IBXC tokens granted to the honor node that generates the block.
The account that receives the reward is specified in the full_nodes parameter.
blockchain_url

commission_size
Percentage of the commission.
The amount of the commission is calculated as a percentage of the total cost of implement the contract. The unit of the commission token is IBXC.
The commission will be transferred to the account address specified in the commission_wallet parameter.

The account address to receive the commission.
The amount of commission is specified by the commission_size parameter.
default_ecosystem_contract
The source code of the default contract in the new ecosystem.
This contract provides access to the ecosystem creator.
default_ecosystem_menu
The source code of the default menu of the new ecosystem.
default_ecosystem_page
The source code of the default page of the new ecosystem.
fuel_rate
The exchange rates of different ecosystem tokens by fuel unit.
The format of this parameter: [["ecosystem_id", "token_to_fuel_rate"], ["ecosystem_id2", "token_to_fuel_rate2"], ...] * ecosystem_id
For example:
[["1","1000000000000"], ["2", "1000"]]
One token of Ecosystem 1 is exchanged for 1,000,000,000,000 fuel units. One token of Ecosystem 2 is exchanged for 1,000 fuel units.
price_create_rate
The fuel rate of a new element.
full_nodes
The list of honor nodes of the blockchain network.
The format of this parameter:
tcp_address
TCP address and port of the node host. Transactions and new blocks will be sent to this host address, which can also be used to obtain the complete blockchain from the first block.
api_address
API address and port of the node host. Through the API address, you can access any function of the platform without using Weaver. See details in RESTful API.
public_key
Public key of the node, which is used to verify the block signature.
gap_between_blocks

All nodes in the network use it to determine when to generate a new block. If the current node does not generate a new block within this time period, the turn passes to the next node in the list of honor nodes.
The minimum value of this parameter is 1 second.
incorrect_blocks_per_day
The number of bad blocks that a node is allowed to generate per day before being banned.
When more than half of the nodes in the network receive the same number of bad blocks from a node, the node will be banned from the network within a time period specified in node_ban_time.

The maximum total fuel fee of a single block.
max_fuel_tx
The maximum total fuel fee of a single transaction.

max_tx_block_per_user
The maximum number of transactions of an account in a block.
max_tx_size
The maximum size of a transaction in bytes.
node_ban_time
The global ban period of the node, in milliseconds.
When more than half of the nodes in the network receive bad blocks from a node up to the number of incorrect_blocks_per_day, the node will be banned in the network for this time period.
node_ban_time_local
The local ban period of the node, in milliseconds.
When a node receives an incorrect block from another node, it will locally ban the sender's node during this time period.
number_of_nodes
The maximum number of honor nodes in the full_nodes parameter.
