Semua bisa dilihat pergerakan aktivitas steemit, sangat canggih

Seingat saya, saya pernah membaca sebuah teori, bahwa semua transaksi di blockchain tercatat di dalam block-block dan tersedia untuk diakses kapan saja, tidak mudah untuk menghapus transaksi-transaksi ini karena mensyaratkan persetujuan mayoritas (kalau bukan seluruh) node (dalam blockchain Steem node-node ini dijalankan oleh orang-orang yang kepada mereka diberi title "Witness"). Begitu yang saya pahami sejauh ini, tapi mungkin @moecki, salah satu witness yang patut didukung di Steem, mungkin bisa menjelaskan ini dengan lebih lanjut, dan mungkin perlu mengoreksi. Thanks in advance.
Bang @hasinbadir, apakah Anda memiliki rasa ketertarikan terhadap teknologi blockchain dan khususnya Steem?

That's right!
Blocks that have already been confirmed by at least 16 witnesses can no longer be changed. As each block is linked to the previous and subsequent blocks (hence the name blockchain), the content of the blocks and the arrangement of the blocks can no longer be changed. Every witness who operates a node also has a copy of the blockchain and can restore it if necessary.

Thanks for answering, one question arises: what is hardfork used for? Is it like a new version of an operating system?

A hard fork is a new version of the chain that involves fundamental changes, especially changes that affect the data that is written to the blocks. Old nodes are then no longer compatible with the blockchain. In the broadest sense, you can use the comparison with the operating system.
The difference is a soft fork, which only makes minimal changes. For example, a new optional function. So perhaps a new app in the operating system.

Are Steem blogging interfaces like steemit.com or steempro.com also on the blockchain (or built with blockchain technology)? Likewise for example with the web application you built https://moecki.online/ or @steemchiller's SteemWorld.org.
Over time, I've seen changes to steemit and steempro (maybe also to SteemWorld and your search engine), if they're all on the blockchain, then it seems like any changes would have to be made via one of the forks?
I remember a fairly ‘hard’ fork in the past, Velicity (if I'm not mistaken it was when Steem introduced Resource Credit, among other things), everyone was aware of its presence because for a few days leading up to and after the hard fork, steemit was unusable, and on the first day after steemit could be used for blogging, the capabilities of users (especially those with low power were very limited compared to before).
Let me try to help with my understanding. A rough comparison of a blockchain is a database - only that steem isn't a typical databse as here each new block of it has a reference to its predecessor, forming a chain.
From an architectural perspective, the web applications have different layers, this is for better scalability, maintenance, development, support, etc.
Usually, the web apps have 3 layers
Those layers could be hosted on the same server or cloud, or not.
For instance, if you trace route any of the steem frontends (steemit.com, upvu.org, moecki's version, etc.) you will see they are located in different parts of the world ;) So those sites(apps) you mention are Business+Presentation layers that use the STEEM blockchain as a database. So they are all off-chain, to answer your question. ;)
In theory, it is possible to store an app on the blockchain but then to execute it, still some external service will be needed to do so, also the blocks are limited in size and a bigger app would be very fragmented.
It's like building a car with Lego parts - it's possible but how good such a car would be? ;)
Another limitation is the STEEM blockchain is text-only.
Long time ago, in the previous century, lol, I worked as a developer for about ten years, on all the three types of layers - now such roles are called a "full-stack developer" but back then there wasn't such a title :)
This has been exciting, Thanks for adding this information, @lightcaptured. =D
Harus lebih banyak yang mengajari, dan untuk waktu pun terkendala oleh hal lain.
Saya telah menggunakan cukup banyak waktu mempelajari Steem dalam waktu yang saya miliki sejak pertama kali saya bergabung pada 2017 lalu, saya memiliki ketertarikan pada teknologi blockchain dan khususnya Steem. Dan terutama sekali ketika saya giat mengikuti kursus-kursus di SEC (sekarang SLC) di masa lalu.
Terima kasih.
Semoga ilmunya bermanfaat untuk semua
Di masa lalu saya telah menulis tidak sedikit (walaupun tidak banyak juga) artikel tentang Steem, bahkan ada beberapa yang menjadi seri (rangkaian tulisan dalam topik yang sama).
Tidak ada tulisan yang bermanfaat untuk semua orang. Orang-orang memiliki kecenderungan mereka sendiri: ketertarikan, hobi, waktu, visi, tujuan. Tulisan jenis tertentu berguna bagi kelompok tertentu.
Dan karena saya menyukai hal-hal terkait blockchain, saya selalu menghargai artikel-artikel dalam topik tersebut, khususnya Steem.
Betul, orang akan tertarik pada hal yang dia sukai dan akan dia tekuni.
