281  Local / Bahasa Indonesia (Indonesian) / Re: BAGAIMANA NASIBMU JIKA FORUM BITCOINTALK TIDAK ADA ⁉️ on: February 17, 2024, 04:38:15 PM
Bagi saya, jika forum ini tidak ada, mungkin nasib saya tidak akan pernah berubah seperti sekarang dimana kini berkat dari forum ini yang dulunya saya sebagai pengangguran yang tidak berpenghasilan kini paling tidak saya sudah bisa membuka usaha sendiri walaupun tidak besar. Saya sangat berterima kasih dengan adanya forum ini karena bagi saya forum ini memiliki peran penting selain bisa mendapatkan penghasilan, di forum ini juga bisa mendapatkan berbagi informasi, dan memfasilitasi pembahasan tentang perkembangan dan isu-isu terkini dalam dunia kripto.
Ya jangan berpasrah diri Gan jika forum ini tidak ada, kesempatan untuk sukses pun masih akan tetap ada terbuka lebar gan, semisalnya sebelumnya forum ini terbentuk banyak koq orang mencapai suksesnya. Ini  tergantung bagaimana dari diri kita sendiri malas atau tidak nya dalam mengejar suatu impian di masa depan.  Ya saya pun berterimakasih banyak pada teman ku yang sudah mengenali forum ini ke saya, cuman sayang nya teman ku ini sudah (almarhum) Al-fatihah selalu buat teman ku ini, semoga apa yang ia ajarkan ilmu nya menjadi bekal di akhirat nanti. Banyak yang di ajarkan oleh beliau dari bounty dan mencapai ke penghasilan setiap minggunya dari signature. Bukan hanya itu saja interaksi antar member senior pun kita mendapatkan bimbingan pengetahuan tentang apa saja yang kita bahas membuat mainset saya berubah tentang apa itu investasi.

Membuat transaksi secara manual (Create Transaction from the Scratch)

Ini merupakan cara yang paling rumit dan bahkan bisa dibilang jarang sekali yang menggunakan cara ini untuk membuat sebuah transaksi. Namun dalam hal ini, saya akan menguraikan caranya, sehingga bisa diketahui bagaimana sebuah RAW Transaction dibuat, disusun, ditandangani dan dikirimkan ke Jaringan blockchain (ini juga merupakan penjelasan secara detail dari membuat transaksi menggunakan cara kedua).

◉ Membuat Transaksi Non-Segwit

  • Pertama-tama harus diketahui Struktur dan susunan dari Transaksi Non-Segwit

Code:
Version >> Input Count >> Inputs (TXID > Index UTXO > Scriptsig Size > Scriptsig > nSequence) >> Output Count >> Outputs (Value > ScriptPubKey Size > ScriptPubKey) >> Locktime

  • Menentukan Version
    Misal dipilih Versi 2, jika direpresentasikan dalam bentuk Hex (4 bytes) Little-endian Format maka akan seperti ini : 02000000

  • Menentukan Jumlah Input
    Untuk 1 Input jika direpresentasikan ke bentuk Hex : 01

  • Menentukan UTXO (TXID) yang akan digunakan pada Input
    Untuk mengetahui UTXO/TXID beserta value amount dan indeknya bisa menggunakan perintah listunspent

Code: (result of listunspent)
    "txid": "e9fa95bdb80bc780ed92bc865d9b6ec07ba0c42a06d34009d6d0bef84a1ad793",
    "vout": 1,
    "address": "n1sQo7UFrRD5KzjXCUyQCrjQs4zaXuFcgt",
    "label": "",
    "scriptPubKey": "76a914df40f4f3462b1e69902f921405e8f2e3bb12005888ac",
    "amount": 0.00045240,

  • In-case kita tidak memiliki Bitcoin Core atau software wallet lainnya, maka untuk mengetahui TXID dari UTXO yang akan digunakan beserta Indeksnya, maka kita bisa melihatnya melalui situs Block Explorer. Yang terpenting kita memiliki Private Key dari address yang related dengan UTXO/TXID tersebut.

tanpa private key apa bisa masih tetap jalan om variabel di console bitcoincore nya, saya heran koq private key saya tidak muncul padahal sudah null

285  Local / Bahasa Indonesia (Indonesian) / Re: [Challenge] Membuat "Message / Data" pada sebuah Transaksi Bitcoin on: February 16, 2024, 12:01:46 PM
Nah yang ini gan yang menjadi problem ane udah muter2 cari cara untuk bisa di mengerti di pikiran ini masih juga gak paham Grin entah lah mungkin otak ane kurang memahami jadi stuck di bagian sini.
Ane udah cari di Google, Youtube (yang ada hanya setup trezor bukan di Bitcoin core) terus nyari - nyari di forum bitcointalk apalagi di sini ane masih kurang memahami nya. Cheesy

Maklum lah gan pemula baru oprek Bitcoin Core Testnet. Cheesy

Sedikit hints mengenai Challenge ini :

* Untuk bisa menghasilkan OP_Return, Transaksi harus di lakukan menggunakan RPC Command createrawtransaction (bisa melalui console Bitcoin Core atau melalui Bitcoin-CLI)
* OP_Return merupakan bagian dari Output Transaksi

https://bitcoincore.org/en/doc/26.0.0/rpc/rawtransactions/createrawtransaction/

Berarti transaksi di kirim ke walllet eyang dulu atau langsung transaksi di console aplikasi Bitcoincore eyang? Jujur saya oleng ni. Kalau aku lihat di mesin pencarian, mereka sudah melakukannya transaksi apa benar begitu eyang

Kalau aku lihat yang versi eyang RPC Command createrawtransaction, setelah mendapatkan hex apakah ada penambahan kode lewat Asc. Saya melihat contohnya begitu si eyang, benar tidak y
Ilustrasi hex:
Hex Ori dari console: 0000......00000
hex tambahan Asc: 00..........(ujung hex)000Gaza13

Anggap saja Gaza13 itu huruf dan angka 8digit misalnya. Setelah itu send,get,decode ya eyang.

Saya juga menemukan versi lainnya dengan menggunakan private key apa benar eyang,  itu saya menghapus beberapa variabelnya.

Ilustrasi versi lain nya
var privateKey = new bitcore.PrivateKey('...');
var utxo = {
  "txId" : "...",
  "outputIndex" : 0,
  "address" : "...",
  "script" : "...",
  "satoshis" : 50000
};

Chelsea is a team that has strength but they can't maintain their consistency to be able to finish in the European zone. It's indeed difficult for Chelsea but that doesn't mean it's impossible for them. With the squad in the Chelsea team, they should be able to get that and the journey this season is still very long and Chelsea can still fight for it.
Even though the match is still quite long, Chelsea needs to improve if they want to finish in the European zone, because as we know in the English league, sometimes many small teams surprisingly beat big or mid-table teams. We saw in the Chelsea vs Wolves match, how Chelsea were unable to beat Wolves at their own home, resulting in Wolves winning the match. Indeed, the quality of Chelsea players is no longer in doubt in all lines of defense and attack. I think this is a valuable lesson to reflect on the problems in Chelsea squad.

We can't just rely on investment for everyday life. Of course, we also have to maintain our survival in any case, whether it's business or staying up late. In my personal opinion, investment is to fight for our money to continue working to make a profit and fight inflation. Indeed, the world of investment certainly has very big risks.

Indeed, many young people are reluctant to open businesses such as agriculture and animal husbandry because they do not want to take risks. If the younger generation does not take steps to take risks, then their lives will be wasted in old age and they will definitely continue to struggle to meet their living needs in old age.

Copenhagen - M.City game is tonight. M.City will win this game with a different score tonight. Copenhagen is the easy team for them.

RB Leipzig - Real Madrid, Real Madrid will win this game. It could be an exciting and enjoyable game, I will watch this game tonight.
Yes, of course many people see that the quality of Manchester City and Real Madrid players is far above the average of their opponents and these two teams are in extraordinary performance. Surely it will be very easy for them to win the match this time. But remember, don't underestimate your opponent too much, even if your opponent doesn't look strong, anything can happen in football. Even though RB Leipzig and Copenhagen are playing at their own headquarters, it certainly increases the enthusiasm or stamina of each player.
292  Economy / Economics / Re: Why we should prioritize investment over saving on: February 13, 2024, 03:41:08 PM
If we want to earn income many times over, of course investment is our choice. If they are already playing in the business world, they don't have any assets to save in the form of savings. On average, they invest in fields that can provide greater profits, so we Everyone must be clever in seeking profits, even though the risk of investing is greater than saving, the results we get from investing are sometimes beyond our predictions.
If someone is in business, they definitely have savings, but 70 or 80 percent of it is diverted to business. It is much better for the money we have to invest than to save. It is better to grow or develop our money than just in the bank.

In my opinion, investment is the same as doing business, even though investment and business both have very big risks and if they are successful then the profits are extraordinary, usually someone has to be patient in managing these two things if they want to be successful. in the future.

Looking the current line up of Inter Milan no doubt they will easily controlling the game, I think Hakan Çalhanoğlu and Henrikh Mkhitaryan will be good attacking and holding midfielder how to make Inter Milan get controlling the games.
For attacking line seems very danger with Inter Milan has duet Lautaro Martínez and Marcus Thuram, I don't think difficult how to score many goals against AS Roma if they are playing with offensive not defensive.
De Rossi must proof his capacity as new roma manager, how smart with his tactical against top team such as Inter Milan after getting three winning in last three matches.
In terms of players, both teams are certainly quite evenly matched in various lines, I was quite surprised by Inter Milan's 5-3-2 and Roma's 4-3-3 formation. Did Inter survive in this match, even though we all know that Inter Milan's performance has improved quite a bit? And As Roma is temporarily ahead with a score of 2-1. Of course As Roma don't want to lose face in front of their supporters, I think the tactics instructed by the coach were quite good in the first half this time.
