Components of a Blockchain ⛓️ ✍️ The components of an open, public blockchain are (usually): 🔴 A peer-to-peer (P2P) network connecting participants and propagating transactions and blocks of verified transactions, based on a standardized "gossip" protocol…
Ethereum’s Components ⛓️
✍️ In Ethereum, the components of a blockchain system described in "Components of a Blockchain" are, more specifically:
🔴 P2P network
Ethereum runs on the Ethereum main network, which is addressable on TCP port 30303, and runs a protocol called ÐΞVp2p.
🔴 Consensus rules
Ethereum’s consensus rules are defined in the reference specification, the Yellow Paper (see Further Reading).
🔴 Transactions
Ethereum transactions are network messages that include (among other things) a sender, recipient, value, and data payload.
🔴 State machine
Ethereum state transitions are processed by the Ethereum Virtual Machine (EVM), a stack-based virtual machine that executes bytecode (machine-language instructions). EVM programs, called "smart contracts," are written in high-level languages (e.g., Solidity) and compiled to bytecode for execution on the EVM.
🔴 Data structures
Ethereum’s state is stored locally on each node as a database (usually Google’s LevelDB), which contains the transactions and system state in a serialized hashed data structure called a Merkle Patricia Tree.
🔴 Consensus algorithm
Ethereum uses Bitcoin’s consensus model, Nakamoto Consensus, which uses sequential single-signature blocks, weighted in importance by PoW to determine the longest chain and therefore the current state. However, there are plans to move to a PoS weighted voting system, codenamed Casper, in the near future.
🔴 Economic security
Ethereum currently uses a PoW algorithm called Ethash, but this will eventually be dropped with the move to PoS at some point in the future.
🔴 Clients
Ethereum has several interoperable implementations of the client software, the most prominent of which are Go-Ethereum (Geth) and Parity.

1. اول از همه، میتونی برای گرفتن رول Colony WL اقدام کنی. برای این کار پیشنهاد میشه محتوای ارزشمند درباره پروژه توی توییتر منتشر کنی. قوانین و مراحل این کار رو میتونی اینجا پیدا کنی: #「📋」how-to-get-wl.
وقتی محتوات رو منتشر کردی، لینک و یه اسکرینشات از اون رو اینجا به اشتراک بذار: #【📝】content-creators
2. علاوه بر این، میتونی شانس خودت رو با ساختن میمهای خلاقانه توی #【😆】meme-creators بیشتر کنی.
3. راستی، حتماً توی کمپین Zealy شرکت کن تا رول OG رو بگیری:
4. همچنین میتونی توی توییتر با صفحه رسمی Pudgy Seals تعامل داشته باشی و امتیاز دیسکورد دریافت کنی (تو رتبهبندی تاثیر داره). راهنماییها رو از این چنلها بخون: #💠│engage و #💠│how-to-engage
5. در نهایت، وقتی رول Colony WL رو گرفتی، میتونی آدرس کیف پول EVM خودت رو از طریق #「🤖」bot-command و با زدن دستور */wallet* ثبت کنی. برای اطلاعات بیشتر، این اطلاعیه رو بخون.
پ.ن: برای دسترسی راحتتر به لینکها و چنلها، اول وارد دیسکورد بشید و بعد این پیامی که اونجا نوشتم رو باز کنید.
باشد که رستگار شویم

اولین روز کاریش بود. احتمالا با ذوق داشت به خوابگاه برمیگشت تا شروع یک مسیر جدید رو جشن بگیره. به ضرب چاقوی سارقان کشته شد و دیگه در جمع ما نیست.
غمِ از دست رفتنش برای ما و روسیاهیش برای مسئولین بیکفایت کوی دانشگاه تهران که امنیت رو فقط در سرکوب اعتراضات دانشجویی تعریف میکنن.
قرار بود با امیرمحمد پادکستی درباره "کامیونیتی منجر بودن" بسازیم. رویداد پیتزا دی هم مهمان اتاق ما بود و راجع به ایردراپها گپ زدیم. مودب، فعال و باهوش و از همه مهمتر سرزنده بود.
امیرمحمد عزیزم دیشب سوگوار نبودنت شدیم و این سوگ با ما میمونه. به امید روزهای بهتر رفیق.
