what is testnet in bitcoin?
-it’s a public test-blockchain where the bitcoin does not have read world value that works similarly as the mainnet blockchain. In this way it is safe to test out some functionality.

what is regtest mode?

  • a local blockchain on your computer and you don’t need to connect to the internet. In programming context, regression-test usually means you check that your new functionality don’t break other parts of the program.

  1. Testnet mimics the real net bitcoin network in how it works but the bitcoin on it doesn’t have real world value. This allows you to test any changes and figure out bugs in a safe environment

2 Regtest stands for regression test mode. It creates a private blockchain, allowing you to adjust and change the parameters to what you want

  1. Regtest:

advantage - you an change parameters to what you want for example creating instant blocks for yourself, allowing you to test things without having to wait on new blocks

disadvantage - you can no test how it would function when connected to a full bitcoin network as you are either the only user on the network or a small local network

testnet:

advantage: It allows you to test in a real bitcoin environment, with a lot of users world wide, real block times etc

disadvantage - you cant set the parameters yourself like in regtest so you will need to wait on things like blocks, and it still costs a few satoshis for a transaction

1. What is testnet in Bitcoin?

The Bitcoin testnet is a public test network, which is not connected to the main chain.

The testnet still functions just like the main chain. Meaning that in order to “test” you also have to wait 10 minutes for each block. And you are connected to other nodes on testnet.

Bitcoin transacted on the testnet have no value on the main chain, as the main chain will not accept these transactions.

2. What is regtest mode?

“For situations where interaction with random peers and blocks is unnecessary or unwanted, Bitcoin Core’s regression test mode (regtest mode) lets you instantly create a brand-new private block chain with the same basic rules as testnet—but one major difference: you choose when to create new blocks, so you have complete control over the environment.
Many developers consider regtest mode the preferred way to develop new applications. The following example will let you create a regtest environment after you first configure bitcoind.”

Regtest mode = A private implementation of the Bitcoin block chain where you control everything and are not connected to other nodes.

3. What is the advantage and disadvantage of each? (TRY TO THINK FOR YOURSELF)

Testnet : Provides real world testing of application. By means of being connected to other nodes and have a actual transaction send and propagated through the network. This is both the advantage and disadvantage. Depending on what it is you are trying to accomplish.

Regtest : Provides the best way for building and developing on Bitcoin. Since there is no block time to hold you up. And you can mine your own blocks in order to develop and test in a “isolated environment”.

Testnet = Real world testing.
Regtest = Building & developing.

*What is testnet in Bitcoin?
Testnet - test network, safer and cheaper for development, where satoshis spent have no real world value, it relaxes some restrictions.
*What is regtest mode?
Regtest - regression test mode, it is good for situation where interaction with other blocks is unwanted, it will allow you to create new block chain with the same rules as testnet, but you can choose when you create and have control over environment. Many developers consider using regtest mode to develop new application.

Homework on Bitcoin Testnet vs Regtest:

  1. Testnet (test network) in Bitcoin is using for development and testing with safe conditions and cheap or even free satoshi.
  2. Regtest (regression test mode) is a private Bitcoin network which developer initiates locally without external peers.
  3. Testnet advantage is a real simulation of main network but it’s a disadvantage because of spending time and satoshi. Regtest advantage is a full privacy and environment control but disadvantage is an absences real conditions.

  1. **What is testnet in Bitcoin?
    Testnet is a safer and cheaper mode to use the bitcoin network i.e the bitcoin test network for development.

  2. **What is regtest mode?
    This is a mode that let you create a new private blockchain and you have a complete control over the environment.

  3. **What is the advantage and disadvantage of each? (TRY TO THINK FOR YOURSELF)
    Advantages of Regtest
    -Complete control over the environment where by you can create in new blocks.
    Disadvantage of Regtest
    -It is designed to run locally i.e there is no public regtest network.
    Advantages of Testnet
    -Coins on the testnet has no real life value and can be obtain for free.
    Disadvantages of Testnet
    -Blocks are mined every ten minutes, You have to wait for a new block.

Testnet is a safe environment without costing real satoshis
Regtest gives more control as you choose when a block is created

Testnet - is closer to real life !
Regtest allows more creativity to test new ideas without constraints

Hi, I recently started studying cryptocurrency to invest money and earn money in the future, so these 3 questions often haunt me. To be honest, I haven’t found a decent description on the Internet. I am very glad that I came across this thread because many have quite informatively described what test net or Regtest is and demonstrated their advantages and disadvantages. I recently only found out that it turns out it is possible to exchange cryptocurrencies for cash and e-money. Before that, I thought it was impossible and that you could only use cryptocurrency as a payment. Still, it turns out it can be sold and receive real money.

  1. testnet is used by developers to test new applications. This does not interact with the mainnet
  2. regtest mode involves working on a private blockchain for testing purposes
  3. testnet is useful if you want to interact with random peers. regtest is useful if you dont want to interact with anyone.

Bitcoin Testnet vs Regtest

  1. What is testnet in Bitcoin?
  • Testnet is an alternative Bitcoin blockchain to be used for testing. This allows developers or Bitcoin testers to experiment, without having to use real Bitcoin or worrying about breaking the main Bitcoin chain.
  1. What is regtest mode?
  • Regtest (regression test) mode creates a local private blockchain where you can adjust the parameters to what you want. You usually use this when it is not needed to communicate with other peers and blocks. An example what you can do with the parameters is you can create blocks instantly.
  1. What is the advantage and disadvantage of each? (TRY TO THINK FOR YOURSELF)

  • Advantage tesnet: testnet is closer to the real chain enviroment an the satoshis you’re using has no real-world value. You don’t have to pay transacion fees.

  • Disadvantage testnet: Need to wait 10 minutes for the next block to be produced (Blocktime).

  • Advantage regtest: You don’t have to be connected to the internet You don’t have any waiting time and no transaction fees.

  • Disadvantage regtest: No interaction with other peers. It’sdifferent from the mainnet.

  1. What is testnet bitcoin?
  • A test blockchain that mimics the mainnet where bitcoins have no real world value and is useful for testing / developing applications.
  1. Regtest mode is for when interactions with random peers or blocks is unwanted , you can create a private blockchain with the same rules as testnet, letting you decide when new blocks are added.
  2. Testnet is more like the mainnet but you have to use a faucet to get bitcoin and you are not in complete control of the blockchain.
    Regtest is the preferred way for most developers to developed a new application where it is easier to add fake bitcoin and faster because you can mine new blocks at any time you want.

  1. The Bitcoin testnet is the network which is specifically designed for testing purposes where the coins don’t have any real-world value.
  2. The regtest mode enables users to create a separate blockchain inside their own PC which can be used for testing purposes.
  3. Advantage on regtest:- Users do not want to wait for each block to be mined as in the Mainnet.
  4. Disadvantage on regtest:- we cant perform complex testing such as the use of random blocks.
  5. Advantage of testnet: Testnet works exactly like the Mainnet.
  6. Disadvantage of testnet: Users don’t get the chance to experiment with coins with real value.

  1. **What is testnet in Bitcoin?
    testnet in Bitcoin is a variant of mainnetwork, where (when testing new apps etc.) the interactions with the network do not have real value and some control features (which are neccessary on mainnet) are disabled because as a tester, you do not need those to be carried out.

  2. **What is regtest mode?
    Regtest mode stands for regression test mode, which is testnet, but where the interaction with other peers is disabled, so that you alone can create and implement blocks, at any given moment, without consensus checks from those other peers. That means you are master over the network and you can create blocks whenever you want with whatever content/ Tx’s you want.

  3. What is the advantage and disadvantage of each? (TRY TO THINK FOR YOURSELF)
    -)Advantage of testnet: you can test new apps / code / improvements of existing apps in an environment without impacting mainnet, and when doing so, no real bitcoin gets lost…
    -)Disadvantage of testnet: There is probably no 100% certainty that whatever is tried and has succeed on testnet, will succeed or is battletested on mainnet because only you tested, not others. If proven wrong, Bitcoin could be at risk when implemented on mainnet.

-)Advantage of regtest mode: You can research implications or situations where a 51% attackon mainnet was succesful and what to do to limit damage when this happened in order to restore the network.
-)Disadvantage of regtest mode: you can not research or explore the social power (Layer 0) of Bitcoin because you do not know how your test results will be changed when other peers com into the mix

  1. When run with no arguments, all Bitcoin Core programs default to Bitcoin’s main network (mainnet). However, for development, it’s safer and cheaper to use Bitcoin’s test network (testnet) where the satoshis spent have no real-world value. Testnet also relaxes some restrictions (such as standard transaction checks) so you can test functions which might currently be disabled by default on mainnet.
    2.For situations where interaction with random peers and blocks is unnecessary or unwanted, Bitcoin Core’s regression test mode (regtest mode) lets you instantly create a brand-new private block chain with the same basic rules as testnet—but one major difference: you choose when to create new blocks, so you have complete control over the environment.
  2. testnet u can test functions that could be disabled on mainnet and is cheaper, regtest is for complete control for developing.

  1. just like bitcoind just fake bitcoin and doesn’t effect mainnet
    2.same as testnet except you have control over when you create new blocks and private
    3.testnet pro, similar to mainnet, con not private.
    regtest pro, private and you control enivornment, con not like mainnet

Hello :grinning:

what is testnet?

  • it is a test network for bitcoin where:
    • btc do not have real value ( can be obtained from a faucet)
    • it is a public blockchain similar to mainnet and involves connections to other peers. Therefore it allows realistic testing taking into account actual time constraints.

what is regtest?

  • a test network for bitcoin where:
    • btc do not have real value
    • the blockchain is private and therefore does not involve actual connections to other peers. Development can be done offline.
    • block creation is instant, therefore allows faster testing without having to wait for block time after each transaction

  1. The test net is a place to test programs and sending transactions that deals with other people.
    2.Regtest is different from the testnet in regtest node you run the whole blockchain on your computer and have the power to mine new blocks whenever.
  2. Regtest is faster and more responsive to testing when you want immediate feedback(ie. you are just figuring out what you’re building and playing around with it). The testnet acts more like mainnet in that you have to wait for blocks to be mined and you are interacting with peers so this is beneficial for testing when you want an environment that better mimics mainnet.

  1. What is testnet in Bitcoin?

A// The network were you have satoshis that have no real world value and also you dont have standard transaction check

  1. What is regtest mode?

A// The network in which you manage your own environment where you can create new private blockchain and you choose when to create a new block

  1. What is the advantage and disadvantage of each? (TRY TO THINK FOR YOURSELF)

A//

TESTNET
PRO

  • More closest to the real bitcoin network
  • A testnet node store much less data

CONS

  • Because is public everybody can connect to it and the test work is not 100% secure.

REGNET

PRO

  • You have your own control(Time,Blocks)

CONS

-Is not a realistic experience and you can not connect to public nodes.

Testnet:

  • Satochis have no real-world value. It’s recommended to use the bitcoin testnet as well.
  • Does not have as many restrictions as mainnet.

Regtest:

  • Flexibility to have no interaction with random peers or unnecessary blocks
  • Allows for immediate creation of brand-new private blocks with the same rules as testnet. Biggest added benefit is that you have complete control over the env.
