Understanding Layer 2 Blockchains with Base as an Example
0 views
Sep 1, 2025
Layer 2 blockchains are built to solve one of crypto’s biggest problems—scalability. In this video, we break down what Layer 2 really means, why it matters, and how Base, Coinbase’s Layer 2 solution, is a prime example of faster and cheaper transactions on Ethereum. We’ll cover: What makes Layer 2 different from Layer 1 How Base works under the hood The benefits (and trade-offs) of using Layer 2 networks Why developers and users are moving to Base If you’re trying to understand where blockchain is heading next, this is the video to watch. #Layer2 #Base #Ethereum #Crypto #CSharpCorner

Hello everyone, I am Goautam Singh from Cesar. Welcome back to the my base
0:05
Cesar. Welcome back to the my base
0:05
Cesar. Welcome back to the my base blockchain series. In this video, we
0:06
blockchain series. In this video, we
0:06
blockchain series. In this video, we will talk about the layer 2 blockchain,
0:08
will talk about the layer 2 blockchain,
0:08
will talk about the layer 2 blockchain, what they are, why they matters and how
0:11
what they are, why they matters and how
0:11
what they are, why they matters and how base is a great example of one. If you
0:13
base is a great example of one. If you
0:13
base is a great example of one. If you felt confused about the layer 1 and
0:15
felt confused about the layer 1 and
0:15
felt confused about the layer 1 and layer 2, don't worry, I will explain it.
0:18
layer 2, don't worry, I will explain it.
0:18
layer 2, don't worry, I will explain it. So, what is layer 2 blockchain? Layer 2
0:20
So, what is layer 2 blockchain? Layer 2
0:20
So, what is layer 2 blockchain? Layer 2 is a blockchain that is built on the top
0:23
is a blockchain that is built on the top
0:23
is a blockchain that is built on the top of layer 1 like Ethereum.
0:26
of layer 1 like Ethereum.
0:26
of layer 1 like Ethereum. Like layer 1 is a main chain. It's
0:29
Like layer 1 is a main chain. It's
0:29
Like layer 1 is a main chain. It's secure but it can be slow and expensive
0:32
secure but it can be slow and expensive
0:32
secure but it can be slow and expensive when lots of people use it.
0:36
when lots of people use it.
0:36
when lots of people use it. So layer 2 helps by moving the traffic
0:38
So layer 2 helps by moving the traffic
0:38
So layer 2 helps by moving the traffic of the main chain. It handles
0:40
of the main chain. It handles
0:40
of the main chain. It handles transaction separately then send the
0:42
transaction separately then send the
0:42
transaction separately then send the final result back to the layer 1. So in
0:45
final result back to the layer 1. So in
0:45
final result back to the layer 1. So in short layer 2 makes the things faster
0:47
short layer 2 makes the things faster
0:47
short layer 2 makes the things faster and cheaper but it still keep the
0:50
and cheaper but it still keep the
0:50
and cheaper but it still keep the security of layer 1. Why do we need
0:52
security of layer 1. Why do we need
0:52
security of layer 1. Why do we need layer 2? Ethanium is a powerful but it
0:56
layer 2? Ethanium is a powerful but it
0:56
layer 2? Ethanium is a powerful but it has some limits. It can be handle only
0:58
has some limits. It can be handle only
0:58
has some limits. It can be handle only 15 to 30 transaction per second. Got
1:03
15 to 30 transaction per second. Got
1:03
15 to 30 transaction per second. Got very high when the network is busy. This
1:06
very high when the network is busy. This
1:06
very high when the network is busy. This slow down the apps GS and defy platform.
1:09
slow down the apps GS and defy platform.
1:09
slow down the apps GS and defy platform. Layer 2 blockchain solves this. They
1:11
Layer 2 blockchain solves this. They
1:11
Layer 2 blockchain solves this. They make it Ethereum more scalable without
1:13
make it Ethereum more scalable without
1:13
make it Ethereum more scalable without changing its base layer. What are
1:15
changing its base layer. What are
1:16
changing its base layer. What are rollups? One of the most popular layer 2
1:18
rollups? One of the most popular layer 2
1:18
rollups? One of the most popular layer 2 technologies is called rollup.
1:22
technologies is called rollup.
1:22
technologies is called rollup. Here how it works. Instead of sending
1:24
Here how it works. Instead of sending
1:24
Here how it works. Instead of sending one transaction at a time to the
1:26
one transaction at a time to the
1:26
one transaction at a time to the Ethereum, rollup bund hundreds of
1:29
Ethereum, rollup bund hundreds of
1:29
Ethereum, rollup bund hundreds of transaction together then sends all the
1:31
transaction together then sends all the
1:31
transaction together then sends all the one batch to the Ethereum main chain.
1:35
one batch to the Ethereum main chain.
1:35
one batch to the Ethereum main chain. This saves space and reduce gas fees.
1:37
This saves space and reduce gas fees.
1:37
This saves space and reduce gas fees. These are the different types of
1:39
These are the different types of
1:39
These are the different types of roll-ups like optimistic rollup, jetk
1:41
roll-ups like optimistic rollup, jetk
1:41
roll-ups like optimistic rollup, jetk rollups and base uses optimistic rollup
1:45
rollups and base uses optimistic rollup
1:45
rollups and base uses optimistic rollup to the op stack. Now we talk about the
1:48
to the op stack. Now we talk about the
1:48
to the op stack. Now we talk about the base which is the real world example of
1:53
base which is the real world example of
1:53
base which is the real world example of layer 2 like base is a layer 2 built by
1:56
layer 2 like base is a layer 2 built by
1:56
layer 2 like base is a layer 2 built by coinbase. It runs on the itanium and
1:58
coinbase. It runs on the itanium and
1:58
coinbase. It runs on the itanium and uses opt stack from optimism. What makes
2:02
uses opt stack from optimism. What makes
2:02
uses opt stack from optimism. What makes bases special? It is fast low cost. It
2:05
bases special? It is fast low cost. It
2:06
bases special? It is fast low cost. It uses rollup to handle the transaction
2:08
uses rollup to handle the transaction
2:08
uses rollup to handle the transaction efficiently. It's EVM compatible so
2:11
efficiently. It's EVM compatible so
2:11
efficiently. It's EVM compatible so Ethereum apps can easily run on the
2:13
Ethereum apps can easily run on the
2:13
Ethereum apps can easily run on the base. It posts data back to the so it is
2:17
base. It posts data back to the so it is
2:18
base. It posts data back to the so it is still secure base is made for both
2:20
still secure base is made for both
2:20
still secure base is made for both developers and everyday users who wants
2:23
developers and everyday users who wants
2:23
developers and everyday users who wants cheaper and faster blockchain access. So
2:28
cheaper and faster blockchain access. So
2:28
cheaper and faster blockchain access. So what about the cost? Gas is a big reason
2:30
what about the cost? Gas is a big reason
2:30
what about the cost? Gas is a big reason of the people love layer 2. Under
2:33
of the people love layer 2. Under
2:33
of the people love layer 2. Under Ethereum gas can cost up to $5 to $50
2:37
Ethereum gas can cost up to $5 to $50
2:37
Ethereum gas can cost up to $5 to $50 depending on the network traffic. But
2:39
depending on the network traffic. But
2:39
depending on the network traffic. But with B gas fees are usually just a few
2:42
with B gas fees are usually just a few
2:42
with B gas fees are usually just a few cents because it batches transaction
2:45
cents because it batches transaction
2:45
cents because it batches transaction shares the cost with others. This this
2:47
shares the cost with others. This this
2:47
shares the cost with others. This this makes B perfect for small payments like
2:50
makes B perfect for small payments like
2:50
makes B perfect for small payments like NFDs, games and more. Benefits of layer
2:53
NFDs, games and more. Benefits of layer
2:53
NFDs, games and more. Benefits of layer 2 with base like lower gas fees, faster
2:58
2 with base like lower gas fees, faster
2:58
2 with base like lower gas fees, faster transaction, less congestion, better
3:00
transaction, less congestion, better
3:00
transaction, less congestion, better user experience, easy for developer to
3:02
user experience, easy for developer to
3:02
user experience, easy for developer to build, deploy apps and because of the
3:04
build, deploy apps and because of the
3:04
build, deploy apps and because of the base is connected to Ethereum, it is
3:06
base is connected to Ethereum, it is
3:06
base is connected to Ethereum, it is very secure and reliable.
3:09
very secure and reliable.
3:09
very secure and reliable. So now you understand what layer to
3:11
So now you understand what layer to
3:11
So now you understand what layer to blockchain and how base works as a great
3:13
blockchain and how base works as a great
