ICOs are said to be the new way to raise money. Against the money raised, the tokens they gave were created and sold on the Ethereum blockchain — meaning that all the trade that took place happened on the Ethereum blockchain and the tokens created are tracked on the Ethereum blockchain. But that is changing. You can think of smart contracts as a set of rules governing something, which cannot be modified ever in the future. They allow a developer to write anything in the form of a smart contract that gets executed by the network.
Both of them can submit their betting amounts to the smart contract. Depending on the weather, the total amount will be sent to either of the two. To fix the problem, Ethereum came up with its native programming language — Solidity. These two limitations have made Ethereum be perceived as merely an ICO platform, rather than a world computer.
Besides these Ethereum-specific disadvantages, it also faces the problems of the blockchain in general — slow speed and no native identity on the blockchain. But blockchains are evolving — we are living in the first few years when the internet was invented. As a huge advocate of blockchain in general, I am quite excited by the research and development happening in the space.
With recent developments, we are seeing new blockchains coming up in the industry that offer so much more: They make developers move to using these newer blockchains for building their decentralized apps and ICOs.
I am particularly excited by development in the blockchains that allow general computations to happen in a decentralized manner. The newer generation of such blockchains offers much more than the ability to write smart contracts. When it comes to writing a smart contract, the biggest obstacle that I hear from the Ethereum developer community is the requirement to learn a new programming language.
I agree that the syntax looks very similar to JavaScript, but it still is a different language and requires you to think of a problem with a different mindset. Tezos blockchain decided to go with a functional programming language for the smart contracts. Another blockchain, NEO , promises to offer support for. Net and Java to begin with, and eventually will allow programs written in Python and Go on its platform. With these four languages supported by NEO, it will already serve about 90 percent of the developer community from the get-go.
The sum of those transactions make up your balance. It is very efficient and lightweight to maintain these records as compared to accounts on an Ethereum-based model. Qtum thus allows for very lightweight smart contracts. Some are targeted toward consumers and some toward large enterprises. On the Ethereum blockchain, your identity is the public key whose private key you own. Every smart contract you deploy gets its own public address identity.
Unlike the pseudonymous model of Ethereum, blockchains like NEO offer users a native identity that can be used across the apps on the blockchain. Some say blockchain is the new internet. There are several mental models in which to fit blockchain, and I, too, believe considering it as the new internet is not a bad analogy. A native identity on the blockchain will have a native identity that can be used to access anything that gets built on the blockchain.
There are several teams working to solve the identity problem on blockchains. The current generation of blockchains gets criticized for how much energy it consumes to power the network. The costs are high because of the consensus method Bitcoin or Ethereum blockchain uses. In any blockchain, periodically all the nodes in the network will have to agree to the updated state of the system. Because the nodes are geographically distributed and are not always keeping track of every other node in the network, they would be required to sync themselves and agree upon the new state of the network.
Currently, the most popular consensus method is proof of work, where every node tries to claim the updated state of the network by solving a cryptographic puzzle. Whoever solves it first gets to tell the network what the updated state is. Everyone agrees to it and proceeds ahead. The disadvantages of this method are that it is slow and expensive. There are several solutions to this problem, with their own pros and cons. While Ethereum is on its way to move consensus to proof of stake, Qtum and Tezos launched with a version of a proof of stake consensus protocol from the start.
Interesting is that Tezos goes a step ahead and offers a decentralized way of governance to adopt any major upgrades to the protocol. Every major upgrade is proposed and voted upon, making the hard forks theoretically rare. On the other hand, NEO uses a delegated Byzantine Fault Tolerance dBFT consensus mechanism that makes it possible to sync up the network a lot quicker without spending a lot of energy. We might see a similar trend when it comes to the blockchain world.
Bitcoin and Ethereum have shown us something that we considered impossible before. But they are far from being perfect. While blockchain is the future, I do not believe the future is what we are living today. We are living among the experiments. What we see around us might be in ruins tomorrow.
What we get as our future might not have been invented yet. With hopes still high and a sharp eye on the industry, I am waiting for the ultimate blockchain. Will it be Ethereum? For now, I am excited to witness one of the largest shifts a human life can live through.
Even if the future does not appear to be near, the future is not far either. More posts by this contributor From barter to blockchain: A history of money.
