 As the number of people using Ethereum has grown, the blockchain has reached certain capacity limitations. This has driven up the cost of using the network, creating the need for "scaling solutions." There are multiple solutions being researched, tested and implemented that take different approaches to achieve similar goals.
 
-The main goal of scalability is to increase transaction speed (faster finality), and transaction throughput (high transactions per second), without sacrificing decentralization or security (more on the [Ethereum vision](/roadmap/vision/)). On the layer 1 Ethereum blockchain, high demand leads to slower transactions and nonviable [gas prices](/developers/docs/gas/). Increasing the network capacity in terms of speed and throughput is fundamental to the meaningful and mass adoption of Ethereum.

 While speed and throughput are important, it is essential that scaling solutions enabling these goals remain decentralized and secure. Keeping the barrier to entry low for node operators is critical in preventing a progression towards centralized and insecure computing power.

 ## Off-chain scaling {#off-chain-scaling}
 
-Off-chain solutions are implemented separately from layer 1 Mainnet - they require no changes to the existing Ethereum protocol. Some solutions, known as "layer 2" solutions, derive their security directly from layer 1 Ethereum consensus, such as [optimistic rollups](/developers/docs/scaling/optimistic-rollups/), [zero-knowledge rollups](/developers/docs/scaling/zk-rollups/) or [state channels](/developers/docs/scaling/state-channels/). Other solutions involve the creation of new chains in various forms that derive their security separately from Mainnet, such as [sidechains](#sidechains), [validiums](#validium), or [plasma chains](#plasma). These solutions communicate with Mainnet, but derive their security differently to obtain a variety of goals.

 - Increased transactions per second greatly improves user experience, and reduces network congestion on Mainnet Ethereum.

 ## Why are so many scaling solutions needed? {#why-do-we-need-these}
 
-- Multiple solutions can help reduce the overall congestion on any one part of the network, and also prevents single points of failure.
+- Multiple solutions can help reduce the overall congestion on any one part of the network and also prevent single points of failure.
 - The whole is greater than the sum of its parts. Different solutions can exist and work in harmony, allowing for an exponential effect on future transaction speed and throughput.
 - Not all solutions require utilizing the Ethereum consensus algorithm directly, and alternatives can offer benefits that would otherwise be difficult to obtain.
 - No one scaling solution is enough to fulfill the [Ethereum vision](/roadmap/vision/).
