Chat Link

What is Chainlink?
Chainlink is a decentralized oracle service designed to connect blockchains with external data sources (such as APIs, data feeds, payment systems, etc.). It allows smart contracts to access off-chain data safely and reliably, making it possible to execute contracts based on these data. Chainlink’s goal is to solve the problem of information isolation between the blockchain and the real world, the so-called “rubber duck problem of smart contracts.”

What are the core principles?
1. Data request (smart contract sends request to Chainlink network)
2. Off-chain oracle nodes (when the oracle nodes receive data requests, they will go to the specified external data source to obtain the required information)
3. Data processing (filtering data)
4. On-chain aggregation (Chainlink uses on-chain aggregation contracts to collect and aggregate data provided by oracle nodes)
5. Incentive mechanism (in order to encourage oracle nodes to provide accurate data and punish nodes that provide incorrect data, Chainlink uses Link tokens as incentives. Data requesters need to pay Link tokens as service fees, while nodes providing data services These tokens can be obtained as rewards)

Why can't smart contracts directly access external requests?
Because smart contracts require certain execution results, the execution environment is closed, and the data obtained from external requests may not be certain. Think about it, can the interface you write yourself provide certain data at all times (idempotence)? It's hard. This requires a decentralized and deterministic data source, which is what the oracle does.

Is Chainlink worth investing in?
Depending on personal needs, I think it's worth it. Maybe Link is debatable, but the oracle is definitely indispensable. The transition from Web2.0 to Web3.0 must use oracles, which are the bridge.

Is there still room for Chainlink to rise?
The former leader in oracles may rise significantly. But we need a wind, a wind for the project to be implemented. It's still a bit far off at the moment, and there are very few people doing solid projects in the bull market. $LINK

Let’s talk about the bull market’s rise

In the bull market, the currency I hold does not rise but falls. Watching other currencies rise suddenly, my mentality collapses. I hesitated to chase the rise, but ended up getting stuck, and the gains I had made rose back. This kind of thing is common, otherwise who would lose money in the bull market?

Is the failure of the bull market to rise the original sin? What nonsense are you talking about? You are here to cut leeks and you are discussing whether it is a crime or not. We leeks are just testing like crazy on the edge of the sickle.

Will the coins I hold increase? The bull market is generally rising, just hold on. It is impossible for us to make all the money, and there is a high probability that if we think this way, we will end up with nothing.

How to choose currency? Technical aspects are given priority. Only when the technical aspects are in place will investors be willing to come. Even if this sponsor gives up halfway, there will still be another sponsor. It won’t return to zero.

What to do during a bull market correction? Just add positions crazily to those that you value, those that are technically better, and those that don’t rise much but fall. This bull market is a bit sudden, and we haven’t absorbed enough chips yet. It is a very happy thing to pick up chips while they are cheap.

Is it necessary to chase other currencies that have skyrocketed? Of course not. I always envy other people’s kids doing hammer work~~~Don’t earn the money you deserve. Other coin families have also worked it out bit by bit. If you want to pick peaches, you will most likely have to pay the price of being covered.

Changing positions back and forth, chasing the rise and killing the fall are all taboos in the bull market. Those who steadily make enough money within their own knowledge are the trendsetters in the bull market.

Chat $ARB

As an L2 project, ARB essentially reduces the burden on L1 projects. To put it bluntly, time-consuming operations such as calculations on Ethereum are outsourced.

ARB belongs to the Optimistic Rollups technology, which assumes that the trust calculator is honest and the participants of the protocol are responsible for their own calculation results and can withstand the inspection of others. If others discover that a participant has cheated, the participant's deposit will be deducted.

The technical details are a bit more complicated, but the general core principle is as described above. Correspondingly, there is L2 implemented by zero-knowledge proof technology, which involves some mathematical things, which will be discussed later.

Is ARB worth investing in right now? I think it's worth it. Two aspects: First, efficiency issues have always been criticized, but any TPS that can improve transactions is worth trying. Second, the projects, communities, and other aspects are all good, so it won’t be a dead end.

What impact does unlocking ARB have? It has some influence but not much. In fact, this is all a psychological influence. Just imagine, if you want to smash down so many unlocks, you have to pull them to a certain height no matter what. I estimate that the depth after ten times the price can almost cover the evacuation of large forces. We retail investors are small in size, so we can just run first.

Is it suitable to open a position now? There is no problem at all in opening a position. It is estimated that after this thing is unlocked, there will be a certain amount of panic to scare us, and then we will start to pull the market. Just a guess, personal judgment.

Talk about today’s plunge.

Bull markets tend to fall sharply, while bear markets tend to rise sharply. Bull market crashes are mostly liquidation of contracts or profit-taking selling, no big deal. Normal market behavior, some people buy and some sell, this is normal.

Is the bull market over? No, once a trend is formed, it doesn’t happen overnight.

What to do now? Add positions to those stocks that have not risen much and are now being affected by the plunge. Such as L2 series.

Will the L2 series really be the point of the hype? Otherwise, there wouldn’t be any other hype points. The performance issues in the Impossible Triangle have always been criticized by web2.0. If this isn't a gimmick, what else could it be? It can’t be just a meme. Stay away from this kind of junk coins. It has nothing to do with us if it spreads to the sky.

Let’s chat $CKB

I have CKB in my holdings. I remember that this coin used to have a name: Super Bitter Coin.

As a technician who has developed blockchain, from a technical point of view, the CKB project is top-notch and can almost be regarded as pursuing the ultimate. From the market analysis, after rising so much, it is normal for prices to fall.

As for whether there is a Dazhuang? Who knows, there is a high probability. But what you need to understand is that the easier it is for Dazhuang to be cheated, he also needs to protect his capital. But he is also one of the slowest and last ones. Now is definitely not the time to run, because the volume of his position will be smashed now, and CKB will directly return to zero.

Why can CKB take off in this bull market? Because I am riding on the east wind of Bitcoin L2.

Is Bitcoin’s L2 a hype gimmick? Yes, Bitcoin also needs an ecosystem, doesn’t it include Lightning Network, Inscription, etc.?

Why does Bitcoin need an ecosystem? If an asset has no liquidity, it is dead. Only through ecology can it be circulated. When the economy circulates, currency is currency.

Is CKB worth taking a position now? It's not worth it. I only opened a position after it rose so much. I can only blame myself for not knowing enough. But it’s worth holding on to now.

Is it worth adding to the position when CKB falls? It is worth it. It is worth adding some positions and playing with the profits you have made from other coins.
