Committee Member

committee_member_create_operation

Create a committee_member object, as a bid to hold a committee_member seat on the network.

Accounts which wish to become committee_members may use this operation to create a committee member object which stakeholders may vote on to approve its position as a committee_member. Field eth_address specifies the address in ethereum to be used in eth sidechain to approve deposits, withdrawals and etc. Field btc_public_key specifies pubkey of this committee member in bitcoin newtwork to be used in btc sidechain to approve deposits, withdrawals and etc.

committee_member_update_operation

Update a committee_member object.

This operation is used by the committee member to update his url, eth_address used in eth sidechain or btc pubkey used in btc sidechain.

committee_member_update_global_parameters_operation

Used by committee_members to update the global parameters of the blockchain. See chain_parameters to get info about parameters which can be modified by this operation.

This operation allows the committee_members to update the global parameters on the blockchain. These control various tunable aspects of the chain, including block and maintenance intervals, maximum data sizes, the fees charged by the network, etc.

This operation may only be used in a proposed transaction, and a proposed transaction which contains this operation must have a review period specified in the current global parameters before it may be accepted.

{
struct fee_parameters_type { uint64_t fee = ECHO_BLOCKCHAIN_PRECISION; };

committee_member_activate_operation

Used by active committee_members to propose activation of committee_member

This operation may only be used in a proposed transaction, and a proposed transaction which contains this operation must have a review period specified in the current global parameters before it may be accepted. To activate a committee member he needs a certain amount of frozen balance specified in global properties. See committee_frozen_balance_to_activate from chain_parameters to get the amount to be frozen.
