# 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.

# 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

Depreciated.

# 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.

# commission wallet

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

    Ecosystem ID.

  • token_to_fuel_rate

    Exchange rate of the token by fuel unit.

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:

[{"api_address":"https://apihost1:port1","public_key":"nodepub1","tcp_address":"tcphost1:port2"},{"api_address":"https://apihost2:port1","public_key":"nodepub2","tcp_address":"tcphost2:port2"}]

  • 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

The time interval (in seconds) of generating two blocks on a node.

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.

# max block generation time

The maximum time for generating a block, in milliseconds. If a block is not successfully generated within this time period, a timeout error will be reported.

# max block size

The maximum size of a block, in bytes.

# max columns

# max tx block

The maximum number of transactions in a single block.

# 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.
