Hi, I’m Chronos, and welcome to Part 5 of the Peercoin Primer. Peercoin is one of the world’s most established cryptocurrencies, and each video in this series will explore a different aspect of it.

In this video, we’re going to talk about Peercoin’s mission. In particular, we will focus on the role of the Peercoin blockchain itself. Sunny King, the anonymous founder of Peercoin, said in 2013: (pause)
“From my point of view, I think the cryptocurrency movement needs at least one ‘backbone’ currency, that maintains a high degree of decentralization, maintains a high level of security, but doesn’t necessarily provide a high volume of transactions.” (pause)
When Sunny talked about Peercoin as a backbone currency, he was actually introducing a concept that has since become known in the broader crypto community as a settlement layer.
In the early days of cryptocurrency, it was believed by many that decentralized blockchain networks would compete with other payment processing networks such as Visa or Mastercard, and even act as a replacement for paper money. However, in reality it turned out that decentralized blockchains struggle to support high transaction volumes and doing so actually degrades a blockchain’s decentralized security. Because of this limitation, it is difficult for decentralized blockchains to be used on a mass scale by a global population.
A more viable path toward global use of cryptocurrency is achieved by shifting the role of the blockchain away from day to day payment processing and towards the role of settlement layer, thus permitting maximum decentralization of the blockchain, while using vertical and horizontal scaling technologies to increase – indirectly - the transaction capacity of blockchains. With vertical and horizontal scaling, rather than transactions taking place directly on the blockchain, they are instead conducted off the blockchain.
Horizontal scaling utilizes sidechains, which are separate and independent blockchains. Sidechains are linked to a parent blockchain through a two-way peg. This two-way peg makes it possible for cryptocurrency and other assets to be exchanged from the parent blockchain to the sidechain. As an example, on the parent blockchain a user sends some of their coins to a specific address, which locks them. After a small waiting period, an equivalent amount of coins are released on the sidechain. As sidechains are usually designed with expanded functionality, the user may now have access to lower cost transactions, smart contracts, near instant payments and greater scalability. When finished using these expanded functions, the user can then settle back on the parent blockchain, reversing the process by sending their coins to a specific sidechain address, which locks them. The coins on the parent chain are then unlocked and become spendable again.
Vertical scaling utilizes separate networks that are built specifically for large volume and high speed processing. These independent networks are not blockchains, but secondary layers that exist on top of the blockchain. Where sidechains allow the blockchain to scale horizontally, secondary layers allow it to scale vertically. Both solutions prevent congestion on the main blockchain by allowing transactions to be offloaded onto off-chain networks, whether they be sidechains or secondary layers. In this way, the blockchain becomes the foundation of a network linked by multiple chains and layers.
A blockchain is a distributed public ledger which records and stores information in such a manner that prevents it from being edited or altered. This immutability means data becomes permanently recorded into the blockchain. This leads to a state of trustless security, where all users of the network can depend on the blockchain’s ability to guarantee the accuracy and immutability of recorded data. This security is the core value of the blockchain, and the main reason why it is utilized as the base of the network.
Continuing with vertical scaling, any independent layers built on top of the blockchain are designed to leverage the permanence of the data stored on the chain. These secondary layers undertake functions that the blockchain is incapable of achieving by itself, if it is to remain decentralized. Together, they form an important relationship. The blockchain records and stores information in a permanent manner, while secondary layers expand utility by creating new ways of interacting with that information. Without an immutable blockchain as the base of the system, the underlying data that secondary layers interact with would be compromised. Equally, without secondary layers to expand beyond existing functionality, the blockchain would be less useful, as data would be stored with fewer ways of interacting with it.
One example of secondary layers in action is the Lightning Network, developed to help scale the Bitcoin blockchain. Transactions are offloaded and processed through Lightning, while the blockchain is used to record final settlement, hence the name settlement layer. Lightning is only one possible secondary layer application. Other examples include atomic swaps, tokens, and smart contract protocols. Another example is a project called Open Transactions. Not only do secondary layers help solve transaction scaling issues, it also gives birth to a broader ecosystem of new utility with the blockchain as its settlement layer.
As Peercoin’s creator Sunny King intended in 2012, the Peercoin blockchain’s mission is to become this settlement layer. This shows incredible forethought, as Bitcoin did not adopt this strategy until years later after it became obvious the blockchain alone could not support transactions on a mass scale.
From the outset, all of Peercoin’s design choices were made with the goal of becoming the definitive settlement layer. We’ve discussed these design choices in videos 1 to 4; they include: removing the conflict of interests between miners and coin holders by allowing coin holders to mint their own blocks; achieving an efficient and inexpensive security protocol based on scarcity of time, rather than electricity; attaining geographical decentralization of minting power block producers; allowing for 1% annual inflation to prevent deflation and incentivize minting; and replacing transaction fees with a continuous block reward, as a means of compensating block producers.
These design choices mean Peercoin actually acts better as a settlement layer than blockchains that rely on security through transaction fees. Given that Peercoin’s security is maintained through a continuous block reward, and not transaction fees, there can never be competition between Peercoin’s block producers and secondary layer node operators for transaction fees. This eliminates the conflict of interests that exist when both settlement and secondary layers chase the same users for fees.

There’s also a great community, very knowledgeable and friendly, on the official forums at talk.peercoin.net. And lastly, there’s a ton more educational material at university.peercoin.net, where you can really get in-depth with this beautiful blockchain.
