All About Lightning Electrum
If you need to cancel a transaction on the spot, or if the cashier repeats the transaction, you can ask the store staff to cancel the transaction on the spot and restore the deposit amount of your account.
In a block, multiple transactions are merged and there is no way to see the details of each single transaction.
Therefore, the use of multi-signature wallets provides additional security. In the Bitcoin ecosystem, it is easy to put them in an Electrum wallet. Multi-signature wallets require confirmation of several private keys in order to sign a transaction.
B: Electrum server can customize messages to appear in the user's electrum light wallet software, giving hackers a chance to broadcast phishing messages.
DAG, there is a ringless graph, there is no concept of blocks in the ringless graph, the entire flowchart is composed of a transaction, each transaction unit records the transaction information of a single user, this way of operation saves the blockchain blocking and packaging process.
There are several Litecoin wallets to choose from! Such a good wallet - Electrum Litecoin wallet! View exclusive reviews on Electrum.
Hackers have launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials.

Electrum and MyEtherWalle users face phishing attacks.
It should be remembered that all BTC transactions are irreversible (therefore, all transaction information should be carefully checked). This is the case, because there is no unified central authority to manage Bitcoin transactions, it is impossible to cancel Bitcoin transactions
Why use Electrum? Here are a dozen of the benefits of electrum wallets.
Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.

One of the features of the ERC777 standard extension is to provide a "hook" mechanism that sends notifications to both parties before and after a transaction is completed and allows it to cancel the transaction, ensuring that the transaction is relatively objective and fair. Because the "hook" function notification takes time to operate, the hacker takes advantage of this to launch a re-entry attack and launch a new transaction when the user's transaction is not completed, disrupting the original trading rhythm.
Now, let's talk about the general business implementation thinking for the TCC model. First, the transaction service (the primary business service) registers with the transaction manager and starts the transaction. In fact, a transaction manager is a conceptual global transaction management mechanism that can be a business logic embedded in the primary business service, or a TCC framework that is drawn out. In fact, it generates a global transaction ID to record the entire transaction link and implements a set of processing logic for nested transactions. When the primary business service invokes all try operations from the business service, the transaction manager logs the related transactions using local transactions, in this case, it records the action record of the call to the inventory service, as well as the action record of the call to the payment service, and sets its status to a "pre-committed" state. Here, calling the Try operation from the business service is the core business code. So, how does the Try operation bind to the Confirm and Cancel operations that correspond to it? In fact, we can write profiles to establish binding relationships, or add both confirm and cancel parameters through Spring's annotations. When all from the business service is successful, the transaction manager performs the Confirm operation through the TCC transaction context slice, setting its state to a "successful" state, otherwise the Cancel operation sets its state to a "pre-committed" state and then retry. Therefore, the TCC model ensures its eventual consistency by compensating.
