What Are Oracles?
Oracles are entities that interface real-world data with decentralized systems. In the decentralized environment, oracles are prominent with blockchain-based products. They give blockchains the ability to interact with off-chain data.
With Ethereum and other decentralized platforms powering the use of smart contracts, accessing data outside these systems bridges the conventional and decentralized environment. Note that oracles are not data sources by themselves. Instead, they collect, query, verify and validate data from different sources and deliver them to smart contracts.
Transmitted data can range from price feeds, payments, temperature from a sensor, scores from a football game, etc. Mostly, oracles are classified based on where they draw their data (software/hardware), the flow of information between them and their sources (inbound/outbound), and whether they’re decentralized or centralized.
Software and hardware oracles fetch data from different sources. For example, software oracles get data from internet-based services such as servers and databases, while hardware oracles receive data from information-reading gadgets such as barcode scanners.
Inbound oracles deliver off-chain data to smart contracts while their outbound counterparts relay information from contracts to the real world. Oracles that rely on a single data provider are centralized while those that interact with multiple sources are considered decentralized.
Most crypto proponents would refer to Chainlink (LINK) and Band Protocol (BAND) as quintessential examples of decentralized oracle networks.
Although multiple contracts and decentralized systems can reference one oracle, there are contract-specific oracles built to serve a single smart contract. Note that individuals with unique subject knowledge can fetch, verify, and validate data for use by blockchain-based agreements. These are known as human oracles.
It is typical in prior Bitcoin cycles that an uptick in new demand tends to come alongside an elevated appetite for speculation. This tends to result in increasingly volatile markets, which is characteristic of macro up-trends in prior Bitcoin cycles.
90-day realized volatility has nearly doubled from 28% to 55% since October 2023, which marked the point where Realized Cap inflows started to accelerate higher.
#BTC made its way perfectly as anticipated for the intraday purpose, but now again making a correction back to zone as support and expected a bounce from there. Price looks like a having a reversal, which have might have a strong times, also weekend is about to kick-in so low volatility is expected too.

What Are Behavioral Biases and How Can We Avoid Them?
Behavioral biases, when left unchecked, can lead to poor crypto trading and investing decisions. In fact, there is an entire field of study called behavioral finance, which combines psychological theory with conventional financial economics. Biases are often unconscious, so you must pay close attention to your behavior to reduce bias-charged decision-making.
1. Overconfidence
The overconfidence bias applies to traders who are too sure of their trading ability, causing them to make risky market decisions or overly frequent trades. You can also be overconfident in assets you have already invested heavily in, leading to a portfolio lacking in diversification.
2. Limited Attention Span
There are countless crypto opportunities available. However, we only have a limited amount of attention to spare to properly understand each option before trading. Furthermore, there is often a lot of market noise surrounding different crypto opportunities. This could lead to trading decisions being made with incorrect or insufficient information.
3. Trend-Chasing
Due to the volatile nature of the crypto market, traders may be misled by a token’s exponential price increase and neglect studying the fundamentals that support this spike. Instead of jumping on the bandwagon, consider assets trading below what you feel is their intrinsic value instead of just focusing on tokens that have performed spectacularly well.
Difference Between ZK Rollup and Optimistic Rollup
The main downside to optimistic rollups compared to zero knowledge rollups is the time that it takes for layer 2 users to be able to withdraw their funds back to the underlying blockchain. As an optimistic rollup has to rely on external validators to check the merkle roots for ‘cheating’ before the state can be updated, there needs to be a sufficient amount of time for validators to check and challenge the activity that has happened on layer 2.
The main advantage to optimistic rollups compared to their zero knowledge equivalents is that they are more generalist and can support smart contracts in a similar way to the underlying smart contract-enabled blockchain. Native support for smart contracts within the rollup means that apps can be launched much easier, without the need for additional development.
Types of Optimistic Rollups
Optimistic rollups are not a single protocol but a class of protocols sharing common features and design choices, including:
—> Execution Model
EVM-compatible rollups use the Ethereum Virtual Machine (EVM) as the base layer, allowing them to run any smart contract that runs on Ethereum without modification. EVM-equivalent rollups use a functionally equivalent virtual machine, enabling them to run most Ethereum smart contracts with minor changes.
EVM-compatible rollups include Optimism and Arbitrum, while EVM-equivalent rollups include Boba Network and zkSync 2.0.
—> Data Availability Solution
Decentralized data availability solutions use a peer-to-peer network or a decentralized storage network (e.g., IPFS) to store and distribute full-block data. Centralized data availability solutions use a single server or a trusted third party to store and provide full-block data.
Decentralized solutions are more secure and censorship-resistant but more expensive and complex. Centralized solutions are cheaper and simpler but more vulnerable and trust-dependent.
Examples of rollups with decentralized data availability include Optimism and Arbitrum, while those with centralized data availability include Boba Network and zkSync 2.0.
—> Fraud Proof Mechanism
Interactive fraud-proof mechanisms require a challenge-response game between the sequencer and validators to verify a block's validity. Non-interactive fraud proof mechanisms utilize cryptographic proofs or witnesses to verify a block's validity without any interaction. Where interactive fraud-proof mechanisms are more flexible and general but more costly and time-consuming, non-interactive mechanisms are more efficient and fast but more restrictive and specialized.
Examples of rollups with interactive fraud-proof mechanisms are Optimism and Arbitrum, while non-interactive fraud-proof mechanisms can be found in Boba Network and zkSync 2.0.

What Is an Optimistic Rollup?
An optimistic rollup is a type layer 2 scaling solution that relies on off-chain computation to trustlessly record transactions that happen in layer 2. Periodically the system publishes a Merkle root of the transactions that happen within the rollup in order to update the "state" of the rollup on the main underlying blockchain. A network of external validators checks the Merkle roots to make sure that they are correct before the state is updated some time later. If an inconsistency arises, then the validator can publish a fraud proof during the dispute period, which can cause the state of the system to be rolled back to the previous valid state.
Optimistic Rollups Explained
An optimistic rollup is a layer-2 scaling solution designed to enhance Ethereum's throughput and latency by moving computation and data storage off-chain. These rollups reduce the load on the Ethereum mainnet and increase its scalability by processing transactions outside of it.
The three main components of an optimistic rollup are:
-> A smart contract on Ethereum
-> A sequencer
-> A set of validators
The smart contract governs the interaction between the layer-2 chain and Ethereum. The sequencer (a third party) collects, orders, and executes transactions on the layer-2 chain. Validators, comprising a group of nodes, monitor the layer-2 chain and submit fraud proofs to the smart contract if they identify any invalid transactions.
Using an optimistic rollup requires users to deposit funds into the Ethereum smart contract. The smart contract then locks the funds and emits an event signaling the deposit. The sequencer receives the event and credits the user with equivalent tokens on the layer-2 chain.
Users can transact freely on the layer-2 chain with other users who have also deposited funds into the smart contract. They sign transactions and submit them to the sequencer, who verifies and adds them to a queue.
Periodically, the sequencer batches thousands of queued transactions into a block and submits it to Ethereum as a single transaction. The block contains minimal data, such as the state root (a Merkle root of the layer-2 chain's state) and the transaction root (a Merkle root of the transactions in the block). The smart contract stores these roots and updates its state accordingly.
The sequencer publishes the full block data off-chain, either on a decentralized storage network (e.g., IPFS) or a centralized server. Validators can access this data and verify that it matches the roots submitted on-chain. If they find any discrepancies, they can submit a fraud proof to the smart contract, which reverts the invalid block and slashes the sequencer's bond.
When a user wants to withdraw funds from the layer-2 chain to Ethereum, they must initiate an exit request on the layer-2 chain. The sequencer includes this request in a block and submits it to Ethereum. The smart contract then unlocks the funds and transfers them to the user's address. However, there is a waiting period (typically one week) before the withdrawal is finalized, during which anyone can challenge the exit with a fraud proof if it is invalid.
Optimistic rollups' key feature is their assumption that all transactions are valid by default, and it only verifies them if a fraud proof is submitted. This enables high scalability without sacrificing security or decentralization.
#ENJ strongly reacted from the support zone and made a decent move. In Hourly TF, price making its structural shift. If you entered there, try to hodl it for a mid-term.

Here's the Analysis of #CELO :
#CELO is been moving down with the market correction and approaching towards the support zone of $0.97 - $1.00. A reaction is expected from the support but market need to slow down a bit, else we'll see a clean break below of the support. Shorting are less probable, buys will play better at some extent.
Our chart tracks supply clusters over time and by coin age, highlighting in blue previous breaks to new ATH prices, signaling a shift to 'red hot supply'. These warmer colors indicate older supply entering circulation, characterizing the 'Euphoria Phase' of Bitcoin bull markets. As prices rise, dormant supply becomes active, reflecting a wealth transfer from long-term holders to new demand. This pattern suggests continued market dynamics favoring higher prices.

#BTC made its rejection from the consolidation range, and made a heavy drop. Price broke through the support zone and tapped into next support zone of $64,800 - $66,050. Sells side is strongly to the downside, so have to wait for the dust to settle down, before entering fresh trades or make any directional bias.

What is (#PBFT) Proof of Byzantine Fault Tolerance ?
Proof of Byzantine Fault Tolerance (#PBFT) is a consensus algorithm used in distributed systems to achieve #consensus among a network of nodes even in the presence of faulty or malicious nodes. It is specifically designed to handle #Byzantine faults, which refer to arbitrary and #malicious behaviors exhibited by nodes in a distributed network.
In #PBFT, a network of nodes forms a consensus group, and each node takes turns acting as a #leader. The consensus process involves a series of rounds where the leader proposes a value or a set of #transactions, and other nodes in the network vote on the proposed value. #Nodes communicate with each other to reach a consensus on the agreed-upon value.
To achieve Byzantine fault tolerance, #PBFT requires a minimum number of correctly functioning #nodes in the network. As long as a two-thirds majority of the nodes are honest and follow the #protocol, PBFT guarantees that the network can agree on a consistent value, even if some nodes are faulty or malicious.
#PBFT is often used in permissioned blockchain networks, where the participants are known and trusted, and the network operates in a more controlled environment. It provides fast finality, low #latency, and high throughput compared to other consensus #algorithms like Proof of Work (PoW) or Proof of Stake (PoS). However, PBFT requires a higher degree of network communication and is less suitable for open and #decentralized networks.
So, now you're wondering, I've never see any coin using this, Which coin uses this Consensus?
—> This is only the Hot Coin in 2016 - 2017 Bull-Run, which is #NEO Coin.

Here's the Analysis of #DOT :
#DOT is been made a strong correction and reached the support zone/ strong flip area around $8.14 - $8.37. Price already reacting there and might building a support with a rejection too. If you're looking for the buys then you can look into here. One thing to note that, daily candle closing above $8.80 will kick-in solid momentum.
Why and When to Use Indicator
1. You can use indicator as a part of your strategy. Using Indicator in the part of entry and exit is the most common method.
2. Use indicator just to add confluence to you bias. You can have strong bias over your entries with the help of the indicator.
3. You can also use indicator to anticipate reversals in the market. But yes you should make sure its probability and should be done on long-term.
4. Though indicator are lagging and some are leading but still you can use it. But we suggest to use price action when it comes to decision.
5. Most importantly is don't fully rely on indicators as it can be totally leading or lagging as mentioned in previous points. So, the indication suggested can be useless or may be big failure for strategy.
#ROSe entered our 2nd buy zone and moved around 6% to 9% in profits. Well, looks like market is exhausted to move further lower and can expect this all to have a rise. Hodl the position with trailing stops and keep locking positions at resistances.

#BTC still moving over the support and consolidating and with that, price rejecting both side from the top and bottom to. Well, there's most chances of getting strong reversal from here and market start trending again. Ig you're holding any alts position, try to stay there as we can see a jump by this weekend.

Here's the Analysis of #SUI :
#SUI is been moving down the market conditions and near towards the trendline. Price is already above the major Resistance area, so a bounce is expected from trendline else we can see a move towards the support zone of $1.28 - $1.37 for the good buying opportunities.
If we segregate for coin-ages younger than 3 months, we can see a sharp increase over recent months, with these newer investors now owning ~44% of the aggregate network wealth. This uptick in younger coins is a direct result of Long-Term Holders spending their coins at higher prices to satisfy the wave of inflowing demand.

What Is an Optimistic Oracle?
An optimistic oracle is an oracle where real-world data is integrated with decentralized systems (e.g. blockchains), and the data is accepted as true if it is not disputed during a certain period. The “optimistic” design differs from a price-feed oracle, where prices are streamed on-chain but without any recourse or error protection.
Because of the unique design, optimistic oracles can be used in different ways than price-feed oracles. In addition to the price of an asset, they can serve arbitrary data, and “long-tail” information requests that might not be feasible for price-feed oracles to support.
The optimistic oracle also protects smart contracts and users against manipulation of the external data feed, since incorrect data can be disputed. This is a unique feature, as other oracle solutions are only as secure as their data feed.
#ENJ continued to push lower and making it way towards the support zone. Well, Price entering there, is our buy zone, but market is very volatile at the moment. A strong bounce is expected from the $0.40 area but take it accordingly.

Here's the Analysis of #FLM :
#FLM is been rejected hard from the Major Resistance Zone of $0.141 - $0.148. Price kept on flipping both side of the zone around $0.127 - $0.200 which is a flip level too. Currently, price broke the supporting trendline, which says bearish words. Market is but unstable so better wait for the opportunities.
We can also see the dominance of Long-Term Holders is increasing relative to all profit taking events. This behavior pattern is typical of all prior Bitcoin cycles. From this, analysts can start to consider LTHs as an increasingly important cohort when assessing the magnitude of sell-side supply pressure moving forwards.
