TH/s, down 7.55% from yesterday. Bitcoin has 14,191 transactions pending confirmation, with a median transaction fee of $1.0649.

Long transaction confirmation cycle, low TPS

Why is there a problem with excessive fees, long confirmation times and low transaction throughput in the blockchain system?

Blockchain.info, Electrum Wallet.

Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support and a very broad user base, many of which like to use Electrum as a cold wallet or multi-signature wallet for Bitcoin or even USDT (Omni). Based on this usage scenario, Electrum is used less frequently on the user's computer. The current version of Electrum is 3.3.8, and previous versions of 3.3.4 are known to have "message defects" that allow an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing to the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more.

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.

The point is that there are important differences between "send" and "receive" transactions, both of which are broadcast to the network. "Send" transactions include a relatively large fee to ensure quick confirmation. "Received" transactions include relatively low fees, which means it may take some time to confirm.

How can I easily double-spend BTC's zero confirmation payment with BTC's REPLACEMENT By Fee feature? Someone posted a demo video on YouTube.

Support for expansion grew in the second half of 2016 because of congestion. The consequence is that the confirmation period is long, and the second is that the fee is high. In the second half of 2016, the transfer fee increased from the previous 3 or 4 cents to two or three yuan, so everyone is aware of this problem.

The transaction fee is low.

On February 6th BTC reached a low of 5920.72 (whichever is the K line of the exchange I track); on April 1st it reached a low of 6427.16, so why didn't I ever say that my wave of decline support looked at the 5920 line? Or the same as my personal experience I to the entity line to confirm the effective support, how long the shadow does not matter, the final line confirmation does not break on the line.

Goldman Sachs reports that blockchain currently has problems with low volumes of transactions, slow transfers, and high costs of formal friction. These problems are fatal in the retail sector because no one is willing to pay a $2-5 fee and more than 10 minutes of confirmation to buy a cup of coffee. But when we assume that the user is booking a hotel room for hundreds of dollars or more, the small fee and 20 minutes or so of confirmation time suddenly become less difficult to accept.

DeViable Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum 3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the link in the prompt to avoid asset losses.

If the trading time is too long (perhaps because you set the Gas fee too low), you can come back later to see if your address has been mapped on the home page.

That is, you understand the high throw low suction (short line), is how short, you understand how long the long line is, this is our first to be clear.

If the quantity of a single withdrawal is less than or equal to the account already has a low fee limit, the low fee withdrawal rule is preferred.

Performance issues are realized from the very beginning of blockchain, and the intuitive experience is speed, which is how long a transaction can be confirmed. The initial bottleneck is the consensus algorithm, with the Nakamoto consensus initially blocking out once in the first 10 minutes, with an average deal confirmation delay of 5 minutes. Ethereum then reduced the blocking interval to 15 seconds, expecting an average trading confirmation delay of 7 seconds. But is it really 7 seconds before it can be confirmed? Not really. At this point, the performance bottleneck becomes throughput, and although the deal confirmation delay is 7 seconds, most transactions are queued unless a high transaction fee is given to queue.

Electrum.

According to slow fog zone news, Electrum fake upgrade tips of the phishing attack has stolen at least 200 BTC, this attack by upgrading Electrum alone can not be avoided, the need for the entire ecological service to make corresponding changes (because Electrum this client is not a full node, and then on the transaction broadcast and the corresponding service side of the message communication, attackers can also deploy malicious server). Slow fog zones remind users that phishing attacks like Electrum require long-term vigilance. The slow fog zone has previously issued an alert for selectrum phishing updates, and hackers who attacked Electrum wallets used Electrum's software to unusually construct malicious software update prompts to induce users to update and download malware usage.

It's important to transfer the BTC from your original Electrum wallet (to a new Electrum wallet, a new wallet generated by a new monemone, and back it up), which is important to prevent possible BTC loss.

Bitcoin fees have been rising since April, when a transaction fee was 0.1 mbtc lower, and now the 0.5mbtc fee is widely available to get a quick confirmation.

What it means to set a fee, and it's harder to benefit from short-term operations. In the case of TPT, it takes up to 2 years to get a low transaction fee if you hold it long enough to get a 1% fee.

JoinMarket can interact with a Bitcoin Core full node to get the history of your wallet in a private way. You can also choose how to use the Electrum server, but you do not encourage regular users to use it. There are also plans to replace the Electrum interface with one that uses client block filtering.

The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding them to check the authenticity of the client's source before logging in. The team published its official website, and the Electrum clients downloaded elsewhere may be problematic.
