• Object verifiers_object.

Changed:

• Wallet api method create_vesting_linear_policy now receive one more argument.
• Type of consensus_assets_prices from std::map<asset_id_type, price> to std::set<price> in global_property_object.
• Type of field incentives in incentives_object from std::map<uint32_t, uint64_t> to std::map<asset_id_type, uint64_t>.

Removed

• Removed apply_new_config method in ethereum sidechain(it had empty body).

Fixed

• Fixed some bugs with stake btc and btc sidechains.

[0.23.0]

Updated Operations Order

Updated Objects Order

Added

• stake_asset flag to asset asset_issuer_permission_flags, that makes asset not transferable to anyone. Only issue and burn allowed.
• consensus_assets to chain_parameters and consensus_assets_prices to global_property_object.
• The ability to account for balances in other assets when selecting verifiers and producers.
• Ethereum stake sidechain feature:
  • stake ETH on Echo network to participate in consensus.
  • sidechain_stake_eth_update_operation, that allowed to send only by committee members when they gets some update from ETH stake sidechain.
  • stake_eth_update_object to store data about stake sidechain deposits
  • SETH asset to standard genesis files.
• Bitcoin stake sidechain feature:
  • stake BTC on Echo network to participate in consensus.
  • Wallet API methods:
    • create_btc_stake_address - create btc stake address for account.
    • get_btc_stake_address - get btc stake address.
  • Database API method get_btc_stake_address
  • Operations:
    • sidechain_stake_btc_create_script_operation, that creates btc stake address
    • sidechain_stake_btc_update_operation, that allowed to send only by committee members when they gets some update from BTC stake sidechain.
  • SBTC asset to standard genesis files.
• Database API method get_transaction_by_id
• Wallet methods get_transaction and get_transaction_by_id
• Fields std::set<asset_id_type> consensus_assets and stake_config stake_sidechain_config to chain_parameters
• Field payed_blocks_in_interval to dynamic_global_property_object needed for current incentives calculation.
• New objects stake_btc_script_object, stake_btc_vout_object, stake_eth_update_object needed for stake sidechain.

Changed

• Changed EETH asset precision to 8.
• Economy logic: increasing the reward and recording for missed blocks in the pool occurs every block
• Database API method get_incentives_info now returns incentives_object.
• --sidechain-btc-testnet flag moved from sidechain plugin to node command line options. That flag now changes logic of Bitcoin addresses generation(generate addresses to mainnet/testnet).
• Wallet methods that returned signed_transaction now returns [signed_transaction, transaction_id_type] pair
• Network Broadcast API methods broadcast_transaction и broadcast_transaction_with_callback now returns transaction_id_type

Removed

• Database API method get_recent_transaction_by_id

Fixed

• Database API methods get_incentives_info can't return one block bug fixed.
• Fixed bug with vm_root empty on zero block.
