Building on top of ethereum
But then thousands of dollars soon traded hands between businesses that were behind the times and those that were savvy enough to rush into the marketplace and gobble up the most popular names. As blockchain and crypto become ever more familiar parts of our collective lexicon, the outlines of Web 3. One potentially valuable contour of Web 3. Much like the old IP addresses of Web 2. For most people or businesses on the blockchain, identifying a wallet requires a long string of alphanumeric values. For example, a Coinbase Wallet, for use on the Ethereum blockchain, might look something like this:.

Building for the Blockchain
Even for those with an understanding of cryptocurrencies, Ethereum and other advanced open blockchain networks can be confusing, especially when people start talking about launching their new cryptocurrency or token on top of Ethereum. This backgrounder will answer that question, but first we need to cover a fair amount of background material.
Bitcoin is a peer-to-peer network. Bitcoin is a computer protocol for electronic cash. Bitcoin is a provably scarce token that will have a positive value if there is demand for it. All of these are true statements, which means that Bitcoin, the word, is used to describe three different things: 1 a group of networked computers on the Internet, 2 a set of rules and procedures for passing data between computers, and 3 valuable tokens that exist as a consequence of these networked computers running that Bitcoin protocol software.
Those valuable tokens, bitcoins, in turn perform at least three functions: 1 people who dedicate computing resources to making the network work i. Many people interested in open blockchain networks started with Bitcoin and never had this distinction entirely spelled-out for them. So, when it comes to a new network like Ethereum, things can become confusing. Ether is the name for the scarce token that emerges as a result of networked computers running the Ethereum protocol and it is also, like bitcoin: 1 a reward for participation, 2 a currency, and 3 a medium for paying fees.
It is a more generalized protocol. Recall that any blockchain technology does the following: it will allow connected computers to reach agreement over shared data.
For Bitcoin, that shared data is a list of bitcoin transactions. This is why the Bitcoin blockchain is commonly referred to as a ledger. We call it a ledger because that word is familiar to non-technical people, but really it is better described as a log or even better a logfile. In computer science, a logfile is just a record of events that occur as a piece of software i.
So the Bitcoin protocol generates this logfile, called the Bitcoin blockchain, and it reflects all the events that happen on the Bitcoin network. The types of events that the Bitcoin protocol allows to be recorded into that logfile are limited and simple—they are the transactions that we discussed earlier, transactions made either as payments between users, fees for use, or as rewards for people that help to make the network and protocol infrastructure work.
Some transactions can be a bit more complex. Here, the logfile is recording an event that is a bit more complicated. The usual event says: Alice sent to Bob. This multi-sig event said: Alice sent to Bob, Carol, and Doug and specified that two of those three people must agree in order to use the funds in the future. In Ethereum, the logfile i. Just like Bitcoin, it can contain a log of transaction-like events where one person sent ether to another, but it can also contain a log of the execution and the results from running any sort of computer program.
So, if I write a computer program like the old Windows game minesweeper, and then append the computer code that powers my game to the Ethereum blockchain, every event that happens in that game clicking a square to reveal either a mine or a free space, number of lives remaining, high scores, etc.
Whenever I or someone else on the Ethereum network plays the game, new game-related events are appended to the Ethereum blockchain e. Player One clicked on square A:4 and blew up.
Moreover, those game-related events are appended to the log simultaneously with any other events generated by any other computer programs currently running on the Ethereum network. The Ethereum blockchain really is like a proper computer logfile; it records every event that occurs while the computer is running.
The big difference is that it is actually logging events redundantly on every one of the computers connected to the Ethereum network. If it was free for anyone to run any type of application on the Ethereum Virtual Machine, the system would quickly become overloaded.
To stop this from happening, the Ethereum protocol makes every computation indeed every step within a computation require a small fee that goes to the particular computer on the network that recorded the official version of the log for that period. This is similar to fees in Bitcoin, where any fees attached to a bitcoin transaction go to the miner who mined the block that included the transaction. How do you pay the fees? With ether, of course. If anyone can run any sort of code for a fee and allow anyone else to interact with the code and trust the result, then Ethereum can be a very useful tool for all sorts of group computational problems.
One obvious use-case is making a token that has, like Bitcoin, a scarce supply. The scarcity of that token is guaranteed because a variable in the application corresponding to total available supply is explicitly declared e. Alternatively, a developer could create a token application that allows someone, or perhaps a group of people, to periodically adjust the total supply in an attempt to create a stable monetary policy.
Either way, the code—whether it specifies a permanent total supply or describes a mechanism for supply changes—is set in stone when it is added to the blockchain. To encourage best practices, there is an open source standard for coding token-issuing ethereum applications. You might ask, why would anyone want to do all of this when we already have bitcoin and ether; why create another new token?!
The simple answer is that even in the real world we often use all sorts of items rather like we use cash. We use tickets, coupons, stock and bond certificates, vouchers, food stamps, deeds, and a variety of other bearer instruments because they entitle the holder to different things.
Rather than do all that with various pieces of paper, or notations on a centralized database, why not make tokens that people can control with their smartphones and whose authenticity can be verified by on an open peer-to-peer network?
So, I might write an Ethereum application that allows anyone to create event tickets, sell them to audiences, and makes ticket-taking and anti-counterfeiting controls easier. People send ether to the application, specify which event they want to attend, and they get a ticket. When the final holder of the ticket arrives at the venue, they simply show the ticket to the organizer by showing them a QR code on their phone.
Events recorded publicly to the ethereum blockchain verify the unbroken chain of title from the ticket seller to its current bearer.
Some people are creating tokens that relate to Internet infrastructure, like a token that can be spent to automatically pay for the cheapest and lowest latency cloud storage on a decentralized network of storage providers. Others may develop an open social network, like Twitter or Facebook but without a company in control, where tokens are used to make small payments for messaging capacity and to prevent spam and robot accounts from ruining the quality of conversations on the network.
The particular value of any token will depend on a variety of factors described in the application code that created it e. Confusing the two is like confusing the gas you put in the car with groceries you put in the car and drive home. Education Cryptocurrency What are Bitcoin and cryptocurrencies?

Writing Smart Contracts in Ethereum Blockchain
Solana, Avalanche and others boast faster, cheaper crypto transactions. Is a technical edge enough, though? Ethereum's problems have left an opening for a number of upstart blockchains that offer faster and cheaper transactions. Ethereum has become the default blockchain for developers looking to build new crypto applications, from NFTs to decentralized finance products.

However, BSC developers have made significant changes in some key areas. The largest change is BSC's consensus mechanism, which allows for cheaper and faster transactions. Active addresses are also an important on-chain metric to consider. Despite being a newer blockchain, BSC recorded a high of 2,, addresses on June 7, — more than double Ethereum's all-time high of , addresses on May 9, So what's the reason behind BSC's sudden massive growth? A lot of it comes down to faster confirmation times and low fees.

What does it mean to issue a token “on top of” Ethereum?
Blockchain technology , the distributed ledger system that underpins the digital currency Bitcoin, is getting a lot of attention from Wall Street lately. With uses ranging from cross-border payments to settlements and clearing of over-the-counter derivatives to streamlining back-office processes, the potential for disruption in the financial industry and elsewhere is growing more real each day. Ethereum was developed to augment and improve on bitcoin, expanding its capabilities. Its blockchain is built with a turing-complete scripting language that can simultaneously run such smart contracts across all nodes and achieve verifiable consensus without the need for a trusted third party such as a court, judge or legal system. It can also be used to execute bets and wagers, to fulfill employment contracts, to act as a trusted escrow for the purchase of high-value items, and to maintain a legitimate decentralized gambling facility. This, however, is likely to change as the protocol is developed further.
