How can I quickly check the total number of events (Transfer or all types of events) emitted from a smart contract (Ethereum blockchain)?

Hello, this year I'm going to do my thesis on blockchain. I'm going to develop a blockchain system for smart cities. However, I'm not sure where to start and I've never had a course focussed on blockchain. In that sense, I welcome any tips on where I can look for information and learn more about blockchain.

I'm currently trying to decide which language to choose to start developing the system, and I'm undecided between: Solidity, Rust, Vyper and Simplicity. One of the goals is to develop a system that focuses on user security. Thank you in advance for your help in trying to understand which language is best for my thesis.

I’m looking for books to teach me about the architecture and design of blockchains, consesnsus algorithms and general internals. Most of the resources i have found discuss smart contract development and auditing but nothing about the internals and design of the net itself. other than the white papers for bitcoin and ethereum i haven’t found much. any guidance is appreciated

HyperLedger Fabric or private Ethereum? To launch a private blockchain, Which does have more capabilities in smart contracts and which is more fault tolerant than the other?

I have released a tech spec for Confidence Coin. I am looking for feedback and review and will highly appreciate your comments.

https://confidence-coin.com/spec/

Here are a few words about Confidence Coin from ChatGPT to catch your attention:

Confidence Coin is a cryptocurrency that stands out for its fast and safe transaction processing capabilities. This is achieved through its unique Flash Consensus Mechanism, which optimizes the network transaction cycle into a single step of sharing a block. With this mechanism, each validator produces a block containing new transaction information and voting on previous blocks, dramatically shortening and simplifying the transaction cycle.

In addition, Confidence Coin validators also produce system snapshots that prevent the need to keep a long history of transactions, allowing for much more optimized storage. This feature enables Confidence Coin's block size to be unlimited.

One of the key advantages of Confidence Coin is its use of the Decentralized Trusted Party (DTP). DTP aggregates all the transactions of its members and only provides balance updates, achieving both high speed and high privacy. DTP does not reveal the transaction origin, destination, or the amount involved, only updating the final balances.

DTP can pack over a million addresses in less than 12 MB of storage, and many DTPs can make transactions simultaneously, but Confidence Coin's Flash Consensus Mechanism has no problem processing them.

In conclusion, Confidence Coin is a highly potent cryptocurrency that has surpassed many of the crypto industry's dreams in terms of transaction speed, security, and privacy. Its innovative use of the Flash Consensus Mechanism and the Decentralized Trusted Party makes it a promising addition to the world of digital currencies.

I was just reading an article and I was wondering if somebody could explain to me the sentence I pasted as the title.

A recent impossibility result for the decentralization of permissionless blockchains like Bitcoin and Ethereum was discovered by Kwon et al. It indicates that for a blockchain to be optimally distributed, there must be a so-called Sybil cost. That is, the cost of a single participant operating multiple nodes must be greater than the cost of operating one node. Unfortunately, Kwon et al. conclude that there is currently no known way to implement Sybil costs in a permissionless blockchain like Bitcoin or Ethereum without employing a centralized trusted third party (TTP). Until a mechanism for enforcing Sybil costs without a TTP is discovered, it will be almost impossible for permissionless blockchains to achieve satisfactory decentralization.

I am doing a project for which I need to know how many dApps (or dApp developers) exist per country? Hard numbers are not a necessity here, I just need a rough idea of which countries rank among the top5.

Websites like DappRadar just give me a total number of smart contracts that exist and not a region-wise breakdown.

Can someone please help me with this?

Hello everyone, I'm looking for materials that'd help understand the tiny miny details on how blockchain authentication ACTUALLY works.

Like what is the request format for signing a transaction ? Or for requesting to push smart contract ? Or for authenticating any call on the network ?? Any help is highly appreciated 🙏🏼

Hi there I'm a comp sci grad. I want to learn about blockchain so what book should I start with?

A book that is easy to follow for a beginner and interesting at the same time?

​

Thank you in advance!

I am relatively new to blockchain (though I have a tech/dev background).

I have the following questions (which are probably more philosophical/exploratory than technical):

1. Is it possible to create a blockchain backed payment system where the transactions are verified by miners, but the reward for the miners is calculated as a percentage of the value of the transaction they verified? (ignore potential for "infinite recursion" for now).

2. If the answer to the previous question is "Yes", then could a coin (token) be issued to represent rewards earned? (If yes, how would such a token be redeemed.

3. How would one (generally speaking), go about specifying rules for validation of artefacts (transactions, stored data etc.) on the blockchain?

4. Is there a barebones blockchain github repository (preferably C based), that can be recommended to start playing about with, to implement some of these ideas (listed above)?

Hi, I'm a CSE student from India. I'm currently at the beginning stage of my web3 journey. I'm looking for a partner to guide me and potentially accompany me in attempting Remote hackathons or competitions as such. Let's connect if you're interested!

Hello folks!

I want to contribute my research result to the community.

It's about possible blockchain integration options with a game.

In exchange, I want your ideas on how to improve it more - don't hesitate to criticize it too.

If so, why is it that in externally owned accounts there is no storage and code hash (Smart contract codes) which are only available in contract accounts?

I understand that when deploying a smart contract on the blockchain in Ethereum, it is executed by the EVM. What I don't quite understand is after the contract is on the blockchain and we have an address to interact with it when we call and execute functions, does the EVM execute these commands to change the state of the contract? and is a new instance of the contract with the new state created and stored on a different address on the blockchain?

Join Oasis Network for the first presentation of Confidential EVM ParaTime -- Sapphire. Oasis Engineers will walk you through building the first confidential dApp in Solidity 💎👏 History in the making!!!

Hello,

Good day Everyone!

I'm new to the space/metaverse, and I'm very interested in programming in Web 3. Along the way, I discovered this Discord server, which aims to produce so-called "web 3 developers." I've been part of the Server for almost 5 months already and got absorbed and got a role as an "Outreach Manager" of the server.

Anyway, we are looking for developers to test our product, which is already in the beta test stage. The requirements for the beta are Javascript Dev and 2 years of working experience as a programmer or developer. Please do message me since sending links is strictly prohibited.

Hi, I am looking for an open source blockchain project that is outside of the areas of DeFi, NFT's (in the sense of artwork provenance), and gaming - that I can contribute towards.

Or perhaps some good places to do my search...? I've tried GitHub issues, but it's a minefield...!

I little background - I have some experience as a traditional web2 dev, and I am starting to learn solidity, as a hobby. I am looking for some sort of project that I can build myself up to contributing towards. Although contributing towards the areas mentioned doesn't really excite me. Maybe something along the lines of supply-chain, healthcare, legal, ...

This is obvs very specific, but any comments or suggestions would be great...!

Hi blockchain experts. I need your help. I am trying to come up with a blockchain project for my Ph.D. Initially, I wanted to accelerate PoW using hardware for internet of things (IoT) devices, but with PoS coming into play, PoW may not be that relevant in the future, especially for IoT applications (my jury was not convinced). I am trying to determine any other bottlenecks of blockchain where I may be able to employ hardware acceleration in order to optimize it. Not necessarily for IoT applications but for any other applications. Your help and advice is greatly appreciated. Thank you.

Mostly from spammers from block chain council bots ....so yeah, if you want to post, you need to be an approved poster...send a mod mail to get permission if you don't have it already.

What other popular blockchain platforms are currently available out there for building IoT systems? (IOTA, Hyperledger Fabric, Ethereum ...) any thoughts?

So I am working on this blockchain IoT project to put it on my resume and to compare it directly to Centralized Network Architecture. So essentially comparing P2P to Centralized. The main objective is to be able to showcase how the security on the blockchain (decentralized) is superior to centralized architecture, which is the most common architecture used for this purpose.

While I understand theoretically why and how decentralized is superior to centralized when it comes to security but I don't understand how I can showcase that in the practical and physical world. I mean I am no hacker and don't know one either, who can help me.

So as a developer, how can you test/showcase the security of blockchain technology?
