The Consensus is the feature in the blockchain that acts as the gatekeeper and determines the validity of a transactions history or rather the coins origin. The Consensus verifies and validates if the coin came from the Proof of Work (the Miner) or the Proof of Stake (the Masternodes) nevertheless if its verified and valid then its based off of truth and accepted into the Blockchains Public ledger for transacting.

Consensus in a Decentralized database is really a process that disrupts the Centralized system by allowing the network of computers to connect and to validate cryptocurrency in a trustless platform by verifying and validating the currency or the transactions origin but the special feature about the Consensus is that its designed to incentivize those who participate in this Economic platform. In a Central Bank or Database their are numerous steps and extensive procedures that must be take to validate multiple ledgers of income or currency and expenses that take a very long time in auditing and validating its origin with no incentive at all.
1/ It means that all decitions are made together and being doble checked. They get to the truth by using maths protocol, cientific metods to verify any transacction. Using Provenance, you get to a consense.
2/ because they incentive , all computers have incentives ,so by telling the trutth, they get financial incentives…if not, tehy loose money
- What does it mean when we say that in blockchain, consensus determine the truth?
Because in blockchain, consensus is when the incentivize network universally agrees on a transaction to be accepted and proven mathematical truth. Which can be verified anytime by other interested parties. - How is this different from how truth is determined in a central database?
In a central database external parties have to trust the data, which can be changed and compromised by the central authority.
- it means that the truth is validated and agreed on collectively by the people
- in a central database there’s a central authority that decides on whats the truth
-
What does it mean when we say that in blockchain, consensus determines the truth?
It means that the colection of nodes validate the data entry using code and not trusting that the information is correct. -
How is this different from how truth is determined in a central database?
Central databases have a central authority and do not use code for truthful validation.
-
What does it mean when we say that in blockchain, consensus determine the truth?
A feature that allows agreement with what is true or un-truth in the database. -
How is this different from how truth is determined in a central database? In a central database you have a person or people controlling and manipulating the network.
1.with the incentive of making money users are tasked with fact checking past transactions to determine whether or not other users actually have the things they claim to own or be apart of. with Consensus, there is no need to trust as nodes determine the truth.
2.central databases can claim any truth they see fit.
- Agreement of network
- There arent multiple databases, single individual decides truth
-
That truth is not determined from a single source (which would mean we would have to trust that source) but from a network of computers all agreeing on what is true.
-
A central database could just posit anything. We would have to trust the maintainers of that database for the truthfulness of its transactions.
-
What’s public in blockchain is visible by everyone and trackable all the way to the roots of What we want to know further Informations about. Single data value can be proved by POW,POS,POC(Work,stake,capability)
-
Different it’s in the way that in the central Database is always someone who has the power to add,delete whatever it’s needed/wanted and we can’t really proove if those changes are appropriate,reliable and not just tailored to person’s/people’s needs.
-
What does it mean when we say that in blockchain, consensus determines the truth?
Transactions in blockchain will be verified by other nodes by comparing the newly added transaction to the blockchain data. In this way nodes can together decide, if the information is true or false. -
How is this different from how truth is determined in a central database?
Central database is single source of truth and the data can be modified, deleted or created without verification.
- Consensus determines truth because all parties have to agree
2.One party is saying something but no one can verify it we have to trust them to be honest.
-
What does it mean when we say that in blockchain, consensus determine the truth?
It means that when a new transaction comes to the network, the majority of the participating network (nodes) need to verify and agree or reject on that transaction. This is done in a very short period of time -
How is this different from how truth is determined in a central database?
In a database information are added by a key user, potentially verified by a controller and audited at the end of the year. This is a lot of room to “bend the truth”… that cannot be verified at the time of the transaction.
1.Consensus determines the truth by verifying information on all the nodes before accepting and adding it to the blockchain. All nodes must agree information is correct.
- A central database can determine its own truth, as its a single data base that can be manipulated and altered. Only the people who access that single database know it’s truth. Thats why blockchain offers a trustless database and all the nodes agree through consensus before information is added to the ledger.
-
What does it mean when we say that in blockchain, consensus determine the truth?
The nodes/miners on the blockchain is the one that verifies the transactions to detum if the transaction is truth at the same time. -
How is this different from how truth is determined in a central database?
In a central database it’s the master over the DB that decides the truth and every transaction.
-
What does it mean when we say that in blockchain, consensus determine the truth?
In BC we call the truth an infromation on which has been agreed on by the network participants. Which means if 51% agree on something, that is the truth. -
How is this different from how truth is determined in a central database?
Only one or a very limited amount of entities decide about the content of the DB. For example a Central Bank decides there will be more fiat in circulation, then it will be. Even if they rob the rest of the people with inflation.
What does it mean when we say that in blockchain, consensus determines the truth?
consensus is determined by verification of data on all components that run the blockchain. these components or nodes of the network used to verify are incentivized to be honest by getting paid. The truth is mathematical code verified by the decentralized system.
How is this different from how truth is determined in a central database?
it is completely different because the truth in current systems are based on minimal verification. The data can be changed by centralized systems to manipulate outcomes based on false truths. this is why these systems are failing as the lies come to truth with the use of blockchain and blockchain like systems. universal truth will always prevail.
Consensus is a big part of removing trust as all parts must agree on making any given decision. With that said, it is a way of creating a trustless network by decentralizing the network ( having no governing authority like you do in a network that is run on databases and is overseen by a person or a group of people like you do in a centralized system), be it the Blockchain or the Ethereum network, as all decisions as to what information is present or missing (funds from the buyer or stock from the seller for example) is reached by a consensus, the group of nodes connected to the network, e.g., if a purchase of a stock has been submitted then all other partakers of the work (miners) decide that all the elements are there, such as funds and stock, in order for the purchase to be completed (mined).
Contrary to a centralized network, if all conditions and criteria can not be verified, it is impossible for the transaction to be executed or mined if you will and by not achieving the execution of the transaction, then the ultimate goal will not be met, which is to ultimately make money. In other words, in a decentralized monetary system, consensus will not be reached if all information submitted is not verifiable again making provenance transparent and genuine. Thus making a decentralized system both safe and a desirable environment to execute transactions.
- It means the blockchain network self determines what is wright. This happens trough verification.
2.There is now verification as we know is in the blockchain network. So a cental database isn’t so reliable as we wish it would be.There could be falsch information.
-
What does it mean when we say that in blockchain, consensus determines the truth?
Because proof of work networks have to agree on additions to the blockchain, people are incentivized to follow the rules making the entire network actually “trustless”. People make money by following the rules. -
How is this different from how truth is determined in a central database?
The small group of people that are in charge of central databases could easily cheat and no one would know because it would be lost somewhere in the code. Also, the incentive, to be honest, would depend on the administrators having personal integrity. While this is admirable it is easier to have a trustless system where people are rewarded by following the rules and punished for cheating without exception.
