Administered Pricing
Administered pricing is a concept introduced by the economist Gardiner Means, referring to the practice where prices are set deliberately by businesses, rather than being determined through atomistic competition — the orthodox economic model where numerous small players compete, and prices fluctuate according to supply and demand.
Administered prices are set by corporations with significant market power, who can set and maintain stable prices over time, regardless of short-term fluctuations in demand or production costs. Means noted that such firms often use mark-up pricing, where prices are set by applying a predetermined mark-up over estimated production costs to achieve desired profit margins, rather than allowing market forces to dictate prices.
Community
The word "community" is derived from the Latin communitas, which comes from communis, meaning "common, public, or shared by all." Combining con- (together) and munis (relating to duties or services), it conveys the idea of people coming together to fulfill shared responsibilities or provide services.
In the context of Tagion, the Community encompasses all verified Community Members (link) actively participating in and contributing to the network, including Consensus (link) and Governance (link) processes.
Notably, Community is a fluid term - a flexible and evolving entity - that may adapt to include new roles and contributors as the network develops and grows.
Community Member
A community member is any individual or entity who has been verified by peers through the network’s Social Scoring System (link). Once verified, community members gain the right to participate in both the consensus process and the governance of the network, contributing to its security, efficiency and decision-making.
Consensus
Consensus refers to the process by which Nodes (link) agree on the validity and order of transactions recorded in the Database (link). It ensures the integrity, security, and trustlessness of the Tagion Network by making sure that all participants maintain a consistent view of the database without relying on a central authority.
In the Tagion Network, consensus is reached using an Asynchronous Byzantine Fault Tolerant (ABFT) consensus algorithm called Hashgraph. In this system:
A Gossip Protocol connects nodes through information sharing.
Timestamps and Ordering establish a chronological event sequence.
Finality emerges as a supermajority consensus, confirming agreed-upon transactions.
Through Hashgraph, Tagion attains decentralised consensus, enabling honest nodes to synchronise even in the face of potentially malicious participants.
Contributors
In a decentralized network, contributors form the foundation, collectively driving its functionality, security, and growth. Unlike traditional centralized systems, where a single entity oversees operations, decentralized networks thrive on the diverse participation of individuals and organizations. These contributors, each bringing their unique strengths, are indispensable in sustaining and advancing the system.
The term "contributor" itself is fluid, encompassing a wide array of roles that may expand as the network matures and new opportunities for engagement emerge. From the outset, however, contributors can be categorized into three groups:
Node Operators
Node operators provide the essential computational infrastructure that powers the network. They validate transactions, propagate messages, execute smart contracts, and maintain the integrity of the database. Depending on their focus, node operators may run Core Nodes (link), which handle the tasks of consensus and security, Relay Nodes (link), which collect, collate, and manage user requests to submit or retrieve data, or Mirror Nodes (link), which store and replicate data to ensure accessibility. Together, these operators sustain the network's reliability and resilience.
Developers
Developers are the architects and innovators of the Tagion Network. They build, maintain, and refine the core protocols and supporting tools. By addressing the evolving needs of the network and its users, developers ensure the system remains robust and scalable.
Governance Participants
Governance Participants play a critical role in shaping the network's future. Through proposals, debates, and voting, they decide, among other things, on protocol upgrades and treasury finances, including fees and rewards. They ensure that the network remains adaptive and aligns with the Manifesto and the interests of its users.
Currency
An implementation/instantiation of the concept of money [link].
Distributed Database
Tagion is a distributed database, not a ledger, designed to enable dynamic and flexible data management. Unlike ledgers that record data as a linear, immutable chain of transactions, Tagion allows for data to be queried, updated, and deleted.
Tagion ensures data integrity and authenticity through an immutable audit trail. Each update to the database is cryptographically signed and verified, creating a traceable history of changes. This guarantees that users can validate the authenticity and integrity of data while avoiding the inefficiencies of sequential ledger systems, such as blockchain.
Federated Subsystem
A Federated Subsystem is an independent network — either public or private — that operates separately from the Tagion Mainnet (link) but leverages the Mainnet for security and trust. These subsystems can be tailored to specific use cases, industries, or communities, providing flexibility in how they manage data and transactions while benefiting from the underlying security provided by Mainnet Nodes.
In a Federated Subsystem, all data remains encrypted within the subsystem, ensuring privacy and confidentiality for users. However, transactional activity — the overall volume and frequency of transactions — is monitored by Mainnet Nodes.
Governance
At its root, the term "governance" comes from the Greek word kybernan, meaning to steer or guide. In the context of a decentralized network like Tagion, governance refers to the system and processes through which decisions are made, rules are set, and changes are implemented. It encompasses both on-chain (link) processes—such as voting and proposal submission—and informal practices, including open discussions and deliberation on proposals.
Money
Since it has many but no definitive meanings even in economics and law, we here operate with the most basic definition: a system of transferable units to facilitate collaboration within a certain constituency. [compare Bindewald 2021]
Network Services
Network services refer to the functionalities provided by the Tagion Mainnet, enabling users to submit and process transactions, create and interact with smart contracts, manage and store data, and participate in governance processes.
Nodes
A node is any device that connects to the network to help maintain the Database (link). Nodes perform various roles, such as storing a copy of the database, validating and propagating transactions, and participating in the consensus process (link).
There are three types of nodes:
Core Nodes:
At the heart of the system, core nodes are tasked with maintaining the database and reaching agreement on the data submitted and stored—a process referred to as consensus (link). These nodes uphold the integrity and security of the system, ensuring that the data stored is accurate and protected.
Relay Nodes:
These nodes act as intermediaries, collecting, collating, and managing user requests to submit or retrieve data. Because they also filter out spam and unnecessary requests, they significantly reduce the load on core nodes, enhancing the overall efficiency of the system.
Mirror Nodes:
Mirror nodes maintain a full or partial snapshot of the database and update that at given self-selected intervals. Their primary function is to facilitate easy and efficient data retrieval for users while also alleviating the demand on core nodes.
On-chain Governance
On-chain governance refers to formal processes—such as submitting proposals, casting votes, and executing decisions—carried out through smart contracts on the network itself. It ensures that decisions are not only transparent but also enforceable and resistant to manipulation.
Open/Closed
Refers to networks being built on Tagion code and being connected (open) or unconnected (closed) to the mainnet. The latter is what we call “sub-systems”, the former need to comply with out licensing T&Cs.
Permission/Un-permissioned
Refers to anybody being able to use a network service, like submitting transaction, with or without permission.
Privat
Not everybody may run a node. Participation is controlled by some entity.
Public
Everybody can run a node. Thus, “decentralized” already implies that the Tagion Mainnet qualifies as “public”. Sub-systems can choose to be set up as privat or public networks.
Tagion Mainnet
The Tagion Mainnet serves as the foundation of the Tagion Ecosystem, operating as a Layer 0 that provides the settlement layer for TGN transactions, the infrastructure facilitating network governance, and the security and interoperability layer that connects and protects the broader network of Federated Subsystems (link). By allowing independent networks to batch and finalize transactions on its secure and immutable ledger, the Mainnet ensures that even private Subsystems remain anchored to the decentralized security of the ecosystem.
Notably, to keep the Mainnet streamlined, applications are primarily run on Federated Sub-systems, reducing the risk of Mainnet bloating and ensuring that the core network remains slick, scalable, and high-performing.
