What is benefit to use Bech32 address?

What is benefit to use Bech32 address?

Today, I saw a release note that from new client which is Bitcoin Core 0.16.0

The note says "Full support for native segwit addresses (BIP173 / Bech32) has now been added."

I would like to know how it is different from P2SH?(I was able to use it through addwitnessaddress command in Bitcoin Core)

And is it acceptable to transfer BTCs to B3ch32 address from legacy address?(And is it also backward-compatible address?)

I would appreciate it if you could explain it for not-so-tech guy.

Thank you.

What exactly is a block?

What exactly is a block? I am trying to understand the Blockchain algorithm used in Bitcoin. I do not get the part how blocks are created. Let’s say transactions occur at some time. Then, if some nodes get these transactions, these verify the transactions are valid and then send it to other nodes. With this verify-send algorithm, almost every node verifies these newly occurred transactions in few seconds. Now, it is a time for a miner to do his job, which I do not understand. He needs to find a nonce which makes a lower value than hash values given in transactions. Question 1 How many transactions should a miner should verify in a single block? For example, if a miner A finds a nonce which gives a lower value than hash values given in 50 transactions, and if a miner B finds a nonce which gives a lower value than hash values given in 70 transacations, would a reward be given only to the miner B? So should a miner appropriately choose how many transacations he will work for? Ques...

Firmware With Unlocked Overclock for Bitmain Antminer Z9 Equihash ASIC Miners

Firmware With Unlocked Overclock for Bitmain Antminer Z9 Equihash ASIC Miners It seems that just like with the newer Antminer Z9 Mini the new faster Antminer Z9 Equihash ASIC miners from Bitmain are arriving with locked overclock functionality in the firmware. We already know that these ASIC miners are overclocking pretty well and you can easily get a nice performance boost over the stock hashrate the devices come with, so why is Bitmain limiting you… it is pretty clear, they want you to buy more units. Fortunately there are alternatives that allow you to overclock your Antminer Z9 miners and get a nice extra performance boost. Initially there was only a modified firmware released by user efudd on Bitcointalk that was sold to interested people, but now there is also a free version of a modified firmware available with unlocked frequencies by smartass111. Of course you are more than welcome to make a donation to the author of the modified firmware in order to support and motivate him....

How to use this nodejs script (by:Raghav Sood) that have been posted on the stackexchange I'm new to javascript I'm trying to use this script from this post (made by Raghav Sood) : Bruteforce bitcoin address - I know the words + public address but not the order var bip39 = require('bip39'); var bitcoin = require('bitcoinjs-lib') var lineReader = require('readline').createInterface({ input: require('fs').createReadStream('addresses.txt') }); var ctr = 1; lineReader.on('line', function (line) { if (ctr%100 == 0) { console.log("Processing #" + ctr); } if (bip39.validateMnemonic(line)) { var roothex = bip39.mnemonicToSeedHex(line); var rootnode = bitcoin.HDNode.fromSeedHex(roothex); var basechild = rootnode.deriveHardened(49) .deriveHardened(0) .deriveHardened(0) .derive(0); for (var i = 0; i < 3; i++) { v...
