Made a number of changes that were required to change the work in the blockchain explorer.
The following work has been done:
[+] Added getTxByHash function for ChainNet class. This function is a wrapper for the dap_chain_net_get_tx_by_hash function, and accordingly searches for a transaction in the network.
[+] Added pkeyHash attribute for the Sign class, which is essentially a wrapper for the dap_sign_get_pkey_hash function and is used to get the public key hash of the signature. Change moved from features-5386 branch.
[+] Added the ChainCommon class, which has the balanceToCoins function, this function is a wrapper for dap_chain_balance_to_coins and converts data into coins.
[*] Changed SDK version to 2.9-34.
