The fact that not many people know is that Esplora is bundled with a based and optimized Electrum server. This Electrum server is derived from Electrs and is now maintained separately by the Blockstream engineering team. Over the past two years, Esplora has become one of the fastest and most scalable Electrum server solutions available for Bitcoin due to continuous updates and performance optimization. Esplora is also the only Electrum server that supports liquid networks.

As of press time, phishing attacks that forged Electrum upgrade notifications have stolen at least 1,450 BTC (the number stolen is officially counted by a user, anti-malware companies Malwarebytes and Electrum), with a total value of approximately $11.6 million. It is worth mentioning that Electrum versions lower than 3.3.4 are vulnerable to such phishing attacks. Users who use Electrum wallets should update to the latest version Electrum 3.3.8 through the official website (electrum.org). At present, v4.0.0 has not been officially released. Version, please do not use the link in the prompt message to update, so as to avoid loss of assets

In recent days, hackers or hacker groups have stolen more than 200 bitcoins worth about $750,000 by attacking the infrastructure of electrum Bitcoin wallets. The attacker is targeting Electrum.

Share Mempool: There are two main functions, one is to synchronize Transaction between different Mempool nodes through the Mempool protocol (mentioned on the first main line), and the other is to store and process Transaction.

The electrum and Electrum-LTC versions below 3.3.3 are vulnerable to phishing attacks in which a malicious server displays a message asking the user to download the fake Electrum. To prevent user exposure, versions older than 3.3 can no longer connect to public servers and must be upgraded. Do not download software updates from sources other than electrum.org and electrum-ltc.org.

Adjustments to gas and mempool have improved congestion.

Note: Electrum-XZC is derived from Electrum and uses different seed phrase criteria, so it cannot be imported.

Bitcoin wallet Electrum now supports Lightning online payments, according to Coindesk on July 11. It has previously been reported that Bitcoin Wallet Electrum has released a beta version of Electrum 4.0, adding support for the Bitcoin Lightning Network.

Mempool. Transactions checked through the admission control component are fed into the authenticater's Mempool, which holds transactions waiting to be executed in the memory buffer (3). Mempool may hold multiple transactions from the same address. Because Mempool can handle multiple transactions at once, it can perform checks, such as verifying that a series of operations at the same address can pay for gas that the access control system cannot pay for. With this shared Mempool protocol (4), a validator can share transactions with other validators in their own Mempool and place transactions received from other validators into their own Mempool.

As mentioned earlier, because electrum light wallets are different from Bitcoin light wallets such as MultiBit or Breadwallet, they cannot communicate directly with bitcoin full nodes and can only communicate with electrum.

Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
