Bitcoin transaction is a section of data confirmed by a signature of Bitcoin. It costs nothing for dishonest full nodes to send unconfirmed fabricated transactions to an SPV wallet. However, they cannot verify whether or not the transaction is actually valid. Some bank wallets and many SPV wallets accepted this longer chain, putting their users bitcoins at risk. Checking his address doesn't seem to solve the problem because if customer uses wallets like Coinbase, Bitstamp etc. Real Example In July 2015, several large Bitcoin miners accidentally produced an invalid block chain several blocks longer than the correct block chain.
The alternative is to allow miners to do whatever they want. Its contents are completely ignored. Currently the best defense against fabricated transactions, besides using Bitcoin Core, is to wait for as many confirmations as possible. Once validated, miners will include this transaction along with others in a new block in the blockchain. Thus any user of group of users who find that block will gain both the reward for the block and the commission fees for every transaction included. When the network finds a new block it includes all information about transactions including their commission.
