Understanding Leased Proof-of-Stake (LPoS)

The concept of leased proof-of-stake (LPoS) aims to boost mining power while tackling inherent issues in proof-of-work (PoW) and refining other forms of proof-of-stake (PoS), such as delegated proof-of-stake (DPoS).

For those familiar with cryptocurrency staking, proof-of-stake (PoS) is a term often encountered. But what exactly is leased proof-of-stake (LPoS), and how does it relate to PoS?

LPoS is essentially a variant of the PoS model, an integral part of blockchain consensus mechanisms where validators stake assets to generate and validate transaction blocks.

Validators in PoS networks typically stake more assets to enhance their chances of block creation. LPoS comes into play here, allowing tokenholders lacking technical expertise or financial resources to lease their tokens to validator nodes, thereby increasing the validators' chances of block creation. In return, tokenholders receive a portion of the transaction fees paid to the validator.

In an LPoS setting, tokenholders can either lease their stake or operate a full node. However, the more tokens staked by a node, the greater its likelihood of being chosen to generate a new block. LPoS enables users to reap mining rewards without directly engaging in the mining process.

How Leased Proof-of-Stake Operates: A Detailed Look

LPoS functions akin to a lottery, where greater stakes translate to higher chances of winning rewards.

So, what are the mechanics behind leased proof of stake? LPoS follows a structured process

1. Create a lease transaction: Tokenholders lease coins to a node, specifying the amount and recipient address, with the option to cancel leases at any time.

2. Await block generation: Leased funds become part of a node's pool, elevating the probability of winning the next-block lottery.

3. Participate in consensus: LPoS allows leasers to engage in the consensus process, with larger nodes enjoying better odds of block generation.

4. Produce blocks: Successful nodes validate transactions, bundle them into blocks, and earn transaction fees as rewards.

5. Distribute rewards: Node operators allocate rewards to leasers based on their stake, with higher stakes yielding larger rewards.

It's essential to note that the leased tokens never leave the leaser's hardware wallet and remain under the tokenholder's complete control. The holder merely associates the chosen node(s) with the tokens and does not transfer ownership to the node.

Neither party can trade or transfer the tokens while the lease is active; the holder can only transact or spend the coins once the lease is canceled.

Understanding Key Features of Leased Proof-of-Stake

Decentralized Token Management

One of the distinctive aspects of LPoS is its decentralized token management, allowing users to lease out their tokens without transferring ownership or enabling trading. This feature ensures that tokens remain secure in cold storage or wallets, enhancing user control and security.

Unpredictable Block Generation

LPoS introduces unpredictability in block generation, as there's no predetermined method to determine which node will generate the next block. However, nodes with larger economic stakes have higher probabilities of winning the right to create new blocks, ensuring a fair distribution of block creation opportunities.

Fixed Token Supply

Unlike some blockchain systems where mining introduces new tokens into circulation, LPoS maintains a fixed token supply by solely allowing token leasing. This approach helps maintain token scarcity and prevents inflation within the network.

Scalability Focus

Scalability is a priority in LPoS development, emphasizing high on-chain scalability over the integration of second-tier applications. This focus ensures that the network can efficiently handle increasing transaction volumes without compromising performance or decentralization.

Reward Distribution

LPoS rewards successful node operators with transaction fees, rather than issuing block token rewards. This method incentivizes node participation and ensures that validators are compensated for their role in securing the network.

Exploring the Role of LPoS in Blockchain Validation

Utilizing Nodes for Transaction Validation

LPoS leverages nodes or network devices to validate transactions within the blockchain network. This node-based validation process employs computational randomness based on each node's financial stake to allocate validation rights fairly.

Factors Influencing Validation Selection

The selection of nodes for validation is influenced by several factors, including the age and size of the staked tokens. Older tokens and larger stakes have higher probabilities of being chosen to validate transactions, ensuring a balanced and secure validation process.

Contrasting PoS with PoW

Unlike proof-of-work (PoW) systems that rely on raw computational power, PoS utilizes passive cryptocurrency deposits for validation, making it more resource-efficient. This shift enhances sustainability and reduces the environmental impact associated with blockchain validation processes.

Leading Blockchain Implementations of LPoS

Two prominent blockchains, Waves and Nix, implement LPoS consensus algorithms for transaction validation. Waves enables users to lease tokens to generating nodes, while Nix employs a permissionless staking mechanism, offering diverse options for token holders to participate in network validation.

Exploring the Advantages of Leased Proof-of-Stake

Passive Investment Opportunities

Engaging in LPoS offers the advantage of passive investment, allowing users to participate in block generation and receive rewards without actively involving themselves in the block-generating process.

Enhanced Participation for Smaller Investors

LPoS protocols set a minimum investment requirement for network participation, enabling smaller investors to participate by leasing cryptocurrency tokens to larger nodes, thereby increasing their chances of receiving rewards.

Resistance to Manipulation Attempts

LPoS protocols implement a generating balance rule that calculates the lowest balance considering leasing over the latest 1,000 blocks, making it difficult to manipulate the system by moving funds between accounts.

Improved Reward Prospects

By rewarding nodes with the largest economic stake in the network, LPoS enhances the chances of receiving rewards for users leasing tokens to larger nodes compared to those operating independently.

Ownership Retention and Low Entry Barriers

With LPoS, leased tokens remain under the owner's control, minimizing the risk of loss, and the process doesn't require mining hardware, reducing barriers to entry for participants.

Exploring LPoS Crypto Mining Alternatives

Diverse Proof-of-Stake Alternatives

While LPoS offers a unique approach to crypto mining, several alternatives utilizing the PoS consensus mechanism exist, providing various options for users to participate in transaction validation and block creation.

Delegated Proof-of-Stake (DPoS)

DPoS allows users to delegate block production to delegates or witnesses through a democratic voting system, where votes are weighted by the number of tokens held on the platform.

Pure Proof-of-Stake (PPoS)

Algorand's blockchain employs PPoS, where users cast votes to select representatives who vote on proposals and propose new blocks, contributing to decentralized application (DApp) development.

Proof-of-Validation (PoV)

PoV achieves consensus through staked validator nodes, where the number of tokens staked determines the validator's voting power. Validators with a significant portion of the network's total voting power validate new blocks by submitting commit votes.

Hybrid Proof-of-Stake (HPoS)

Some LPoS protocols integrate elements of both PoS and PoW, utilizing PoW to create new blocks and PoS to validate them, combining the strengths of both consensus mechanisms for enhanced network security and efficiency.
