Changed

• Time now isn't updating in dynamic_global_properties on empty blocks. That fixes set of expiration time during empty blocksвыпуска пустых блоков

• Field _cert in block is now of type signatures_t.(as _cert.signatures before)

Added

• Field delegate added to the block. New structure:

  struct block_header
  {
    block_id_type            previous;
    uint64_t                 round;
    fc::time_point_sec       timestamp;
    account_id_type          account;
    account_id_type          delegate;
    checksum_type            transaction_merkle_root;
    std::vector<std::string> vm_root;
    echo::rand::signatures_t prev_signatures;
  };
  struct signed_block_header : public block_header
  {
    eddsa::signature_t         ed_signature;
    echo::rand::rand_t         rand;
    echo::rand::signatures_t   cert;
  };
  struct signed_block : public signed_block_header
  {
    checksum_type calculate_merkle_root() const;
    vector<processed_transaction> transactions;
  };

• Changed sidechain::config. Fields erc20_withdraw_topic, gas_price. New structure:

  struct config
  {
    eth_address_type eth_contract_address;
    eth_method  eth_committee_update_method;
    eth_method  eth_gen_address_method;
    eth_method  eth_withdraw_method;
    eth_method  eth_update_addr_method;
    eth_method  eth_withdraw_token_method;
    eth_method  eth_collect_tokens_method;
    eth_topic_type eth_committee_updated_topic;
    eth_topic_type eth_gen_address_topic;
    eth_topic_type eth_deposit_topic;
    eth_topic_type eth_withdraw_topic;
    eth_topic_type erc20_deposit_topic;
    eth_topic_type erc20_withdraw_topic;
    asset_id_type ETH_asset_id;
    sidechain_fines fines;
    uint32_t waiting_blocks;
    gas_price_type gas_price;
  };
