get single row as a map

GetAddresses returns an array of addresses stored in the wallet file

Return info about transaction settings

Call this when network operation with some node failed. It will analise error and do some actios to remember state of this node

Sets ogging to STDOUT

New transaction appeared in a pool. Block maker should try to do new block if no anough transactions it will just send this TX to all known nodes

Convert to string in format host:port

truncate table

deescape value , remove quotes. returns only value that is set for column

Read record from chain table.

Transaction operations and cache manager

check if this pubkey can execute this query

Read given amount of bytes from connection

Add new block to blockchain. It can be executed when new block was created locally or received from other node

Check if blockchain already exists. If no, we will not allow most of operations It is needed to create it first

Init SQL transactions manager

GetTransactionFromBlock finds a transaction by its ID in given block If block is known . It worsk much faster then FindTransaction

Info about a parsed query. Check if is update (insert, update, delete, create table, drop table)

build independed transaction from normal output

Creates new Blockchain Iterator . Can be used to do something with blockchain from outside

Send inventory. Blocks hashes or transactions IDs

* * New Block added * Input of all tranactions are removed from unspent * OUtput of all transactions are added to unspent * Update the UTXO set with t

This is executed when a block is canceled. All input transactions must be return to "unspent" And all output must be deleted from "unspent"

Create Network Client object. We do this when a node server is running and we need to send command to it (indtead of accessing database directly)

make SQL query manager

======================================================================================== this does all work. It checks query, decides if ll data are p

ReadLenEncodedInteger returns parsed length-encoded integer and it's offset. See https://mariadb.com/kb/en/mariadb/protocol-data-types/#length-encoded

Serialize. We need this to store data in DB in bytes

SkipPacketHeader rewinds reader to packet payload

Base58Encode encodes a byte array to Base58

Builds a command data. It prepares a slice of bytes from given data

Checks if a block exists in the chain. It will go over blocks list

Check if there were recent input connects

Receive ist of hashes and return a hash that is in the chain defined by top hash This function is used for transactions. to understand if a transactio

Clone node

returns list of transactions in prepared block

* * Createes node object. Node does all work related to acces to bockchain and DB */

* * Remove all transactions from this cache listed in a block. * Is used when new block added and transactions are approved now */

Deserialize list of hashes

Deserialize data from bytes loaded fom DB

Send command to block builder to start doing new block. It will check if there are eenough transactions if no anough it will just continue to wait

Lock signs the output

Init wallet client object. This will manage execution of tasks related to a wallet

Checks whether the transaction is currency transaction (sends money to somewhere)

LoadFromFile loads wallets from the file

Parse from string

MakeWallet creates Wallet. It generates new keys pair and assign to the object

NewProofOfWork builds and returns a ProofOfWork object The object can be used to find a hash for the block

open connection if it is not yet opened

prepare data to sign a transaction this return []bytes. it is bytes representation of a TX.

Received new transaction . This must verify and if all ok it adds to the pool

Send own version to all known node

get QueryManager object
