『一』 2. What is the difference between blockchain trust and traditional model trust?

The difference between blockchain trust and traditional model trust is as follows.
1. The most different thing about trust in the blockchain is that it uses mathematics, computer technology and encryption to make the record of information unchangeable, and writes the cooperation agreement on the blockchain through smart contracts, and finally in the conditions The contract is automatically executed after satisfaction. Blockchain eliminates trusted third parties. Through blockchain, people do not need to 100% trust each other or trust third-party institutions. It does not eliminate trust issues, nor does it completely eliminate the need to consider trust issues during the cooperation process. , people still need to trust, but the object of trust is changed from people and organizations to the blockchain network composed of consensus mechanism.
2. The traditional trust system mainly comes from two aspects: country and culture. The state uses its own credibility and public power to endorse the trust of both parties; culture refers to some implicit rules, such as the trust system of various regional customs and the possible emergence of private third-party institutions. The cost of state execution is too high, and it is impossible to rely on the state for everything. The cultivation of cultural trust takes too long and cannot meet everyone's needs. Society is very complex. It is impossible to sign a contract for everything, and it is impossible for the state to intervene in everything.

『二』The trust of blockchain is based on the consensus of a large number of participants. What kind of trust mechanism is it?

It is not a consensus mechanism, but a distributed accounting , recorded currency transaction records, these records are said to not change, a distributed accounting method written with technology

『三』What is blockchain technology, what are its benefits, and what is the establishment of Digital Trust

The recent surge in value of digital currencies since their first emergence in 2009 has sparked discussions in the security community about the benefits of blockchain. Blockchain is a technology that can facilitate the type of trust that is sorely lacking in certain digital transactions.

Today, people are exchanging cryptocurrencies at an increasing rate. But what makes cryptocurrencies so trustworthy? The answer is simple: everyone has their own blockchain.

What is blockchain technology, what are its benefits, and what is building digital trust?

Shifting the Burden of Trust

When we deposit money somewhere, we trust that it will not modify our account. Likewise, when we make a retail transaction, we expect to get enough goods in exchange for the money we spend. By adopting blockchain, cryptocurrency providers have removed the burden of trust from third-party financial institutions

Blockchain is a peer-to-peer network database that breaks each transaction into its own blocks. In addition to cryptocurrency transactions, these blocks can also contain other sensitive assets such as identity information, patents, land titles, medical data, and more.

What is blockchain technology, what are its benefits, and what is building digital trust?

Once transactions are grouped into a block, a hash is assigned to the block so users can easily detect changes to the data. A block may contain a hash of the previous block, creating a block of blocks. This allows security professionals to trace the blockchain back to the first block or the genesis block when an attacker attempts to modify a transaction. Any changes will alter the hash of the block, requiring a potential threat actor to modify all blocks in the chain to complete the attack. For this reason, most cybercriminals believe that attacking blockchains and targets is unrealistic.

More benefits of blockchain

The blockchain is distributed among all participating nodes in the network, so anyone who joins the network can access the entire blockchain . Participants can collectively assess the effectiveness of the entire chain, meaning a potential attacker would need to control more than half of the participants to alter the final blockchain.

The mechanism of this consensus varies depending on the blockchain implementation. For example, one of the most hyped coins uses proof of work, which is a mathematical challenge that participants must solve in order to add a block to the chain. Other methods include proof of stake, proof of activity, and selective endorsement, each with its own advantages and limitations.

By examining the blockchain’s audit trail, participants can see a complete record of who owns a given asset, coin or token throughout its lifecycle. In other words, they can trace an asset’s origins and past transactions. Public key encryption further ensures non-repudiation and confidentiality.

No Limitations

Today, blockchain is often used as a currency ledger to facilitate smart contracts and identity management. In addition, there are projects building database networks that use distributed technology to serve supply chains, real estate, voting systems, and more.

After all, a technology actually guarantees trust between participants and provides visibility into sensitive transactions. As encryption becomes more popular and the need for verification increases, blockchain technology will also get greater improvements

『四』Blockchain Principles

< p>Blockchain is a technology, but it is not a single technology, but the result of the integration of multiple technologies, including cryptography, mathematics, economics, network science, etc. You can think of it as a distributed shared accounting technology, or as a database, but this database is jointly maintained by all nodes on the chain, and each node has a ledger, because all nodes The ledgers are consistent, different nodes can trust each other, and there is no doubt about the data, so everyone says that the blockchain has technically achieved trust. For detailed professional technology, you can consult some professional technology companies. For example: Jinbo Technology, which focuses on developing blockchain-related products, has a professional R&D team and complete after-sales service. You can callCall for consultation.

『Wu』 Why is the blockchain a machine for creating trust?

In the blockchain system, bookkeepers and people participating in the competition are selected according to a set of competition rules. Everyone has a chance to win and be elected as bookkeeper. Let's assume that this rule is a Rubik's Cube competition. Whoever solves the Rubik's Cube first will get the accounting rights. This reflects a feature of blockchain accounting: decentralized accounting. The account keeper is randomly generated by playing the Rubik's Cube game to ensure that the account keeper is no longer a centralized organization.

『Lu』How blockchain will open the door to trust

According to reports, there were 58 blockchain investment events in my country in the first quarter of this year, with a total investment of 681 million yuan. Blockchain: Whether it can open the door to trust has once again triggered heated discussions.

Data from third-party research institutions say that according to incomplete statistics, investment institutions invested a total of 1.271 billion yuan in the blockchain field last year and made 100 investments. In the first quarter of 2018, there were 58 blockchain investment events, with a total investment of 681 million yuan. Capital also regards blockchain as another "window" after the sharing economy and artificial intelligence.

『撒』How to do blockchain

It is necessary to establish a data layer, a network layer, a consensus layer, an incentive layer, Contract layer and application layer.

1. The data layer encapsulates the underlying data blocks and related data encryption and timestamps and other basic data and basic algorithms;

2. The network layer includes distribution

3. The consensus layer mainly encapsulates various consensus algorithms of network nodes;

4. The incentive layer integrates economic factors Into the blockchain technology system, it mainly includes the issuance mechanism and distribution mechanism of economic incentives;

5. The contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the programmable feature of the blockchain The basis;

6. The application layer encapsulates various application scenarios and cases of the blockchain.

(7) How does blockchain build trust? Extended reading

General Secretary Xi Jinping emphasized at the 18th collective study session of the Political Bureau of the CPC Central Committee that “use blockchain as a core technology to independently "An important breakthrough for innovation" and "accelerating the development of blockchain technology and industrial innovation."

The forward-looking judgment of the Party Central Committee has brought "blockchain" into the public eye and has become a common concern for financial capital, the real economy and social public opinion.

From network power to big data, from media convergence to blockchain, the Political Bureau of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, demonstrating the direction, forward-looking judgment and future foresight of the Party Central Committee, leading It follows the pace of China's industrial reform and economic transformation. This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves mathematics, cryptography, the Internet and computer programming.Cheng and many other scientific and technical issues. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.
