At the heart of Aleo are three key stakeholders: stakeholders, verifiers and validators. Let’s take a look at how each contributes to the ALEO network and how they work together to create a mutually beneficial ecosystem.

Stakers: network support

Stakers play an important role in the Aleo network by locking in Aleo credits, helping validators reach consensus and keeping the network secure. Credit blocking not only contributes to the security of the network, but also rewards participation.

Proofreaders: help create proofs

Proofreaders use special equipment to create evidence and solve puzzles to earn Aleo credits. These proofs are an integral component of zero-knowledge proofs integrated into the blockchain and guarantee the confidentiality and security of transactions in the network.

Validators: maintaining consensus

Validators are the backbone of the Aleo network and are responsible for initializing nodes, validating transactions, and joining consensus to add new blocks.

The interaction between these stakeholders is at the heart of the Aleo network

Stakeholders support validators: Stakeholders provide Aleo credits needed by validators to participate in the consensus process. Validators must have at least 1 million Aleo credits to begin their role.

Validator Transaction Verification: Validator verifies transactions on an open source distributed network by verifying zero-knowledge proofs, ensuring the integrity and correctness of the ledger.

Validators generate proofs: The validator generates proofs and solves puzzles that the verifier checks and includes in the block. This cooperation between the verifier and the validator is incentivized by a reward from the network.

Consensus mechanism: The validator participates in a consensus mechanism that ensures agreement on the state of the Aleo network blockchain and verifies transactions in a secure and efficient way.

Implementation of the AleoBFT consensus

AleoBFT is a proof of innovation consensus algorithm developed specifically for Aleo and inspired by the Bullshark/Narwhal model. One of the distinctive features of AleoBFT is the implementation of a new consensus algorithm that resembles the previous Proof-of-Suinct Work model Coinbase puzzle resembles the previous Proof-of-Suinct Work model.

The Coinbase puzzle is solved by the validator of each block and provides a specific share of the block reward. In addition to contributing to the consensus algorithm, it acts as a transaction on the network, extending the benefit beyond the consensus.

Benefits of ALEO

ALEO has advantages that make it attractive to both developers and users.

Cost-effectiveness: Aleo allows users to package information off-chain and upload it as lightweight evidence, significantly reducing network fees and making network participation more accessible and cheaper.

Security: Using the proven security of the Proof of Stake model, Aleo allows users to reduce the amount of sensitive data they share through zero-knowledge proofs, increasing privacy and security.

Participatory economy: Aleo credits encourage users to contribute to the security and functionality of the network, fostering a collaborative ecosystem where all participants play a key role.

As such, Aleo is essential in blockchain technology, offering a unique combination of efficiency, security and inclusiveness.

1 Value stability

The main thing that stablecoins and algorithmic stablecoins have in common is that they all have high stability in terms of price. This stability makes it easy for users to trade in the digital currency market, and it can also be used as a store of value.

2 Asset reserve

Stablecoins are usually issued by companies, and each USDT, DAI, and USDC circulating in the market is pegged to the net asset value of one US dollar. Companies typically hold asset reserves equivalent to the total amount of stablecoins in order to ensure that their aggregate market value does not exceed the collateral that backs them. In contrast, algorithmic stablecoins do not rely on any reserves and endorsements, but use algorithms and supply and demand to control prices.

3 Credibility and listing channels

Since stablecoins are issued by companies, they usually need to be inspected and approved by regulatory audit institutions. The endorsement and auditing of these funds make stablecoins more credible, so they are easier to list on various digital currency trading platforms and are widely used. Relatively speaking, stablecoins with different algorithms and unified governance standards are considered difficult to obtain approval for specific compliance policies. Due to the lack of corresponding review and certification mechanisms, these algorithmic stablecoins may be difficult to be widely used on multiple platforms.

4 Supply and volatility

The supply of algorithmic stablecoins is related to changes in market demand, which means that as demand increases or decreases, its market value and supply will also change. Stablecoins, on the other hand, are unlikely to be oversupplied or undersupplied, because their total amount is fully controlled by the reserve system of the endorsing institution

Which is better?

Both stablecoins and algorithmic stablecoins have unique strengths and weaknesses. Stablecoins rely on asset reserves to support their value, so they are relatively stable, but they need to be supervised by audit institutions, and the listing process is relatively complicated; algorithmic stablecoins do not need to rely on institutions, and their algorithm support is relatively transparent, but the price will follow market demand. Changes cause volatility. On the whole, stablecoins are more popular with users and widely used in practical scenarios. However, as the technology of algorithmic stablecoins matures and develops day by day, the role and status of algorithmic stablecoins in the cryptocurrency market are expected to be further enhanced in the future.

尽管如此，传统游戏发行商还是以牺牲玩家价值和福祉为代价优化公司利润。他们之所以能够做到这一点，是因为他们对游戏的开发、发行和管理拥有端到端的所有权和控制权。

美国艺电公司（Electronic Arts，EA）就是一个很好的例子，这家游戏公司在游戏社区中扮演了一个恶棍般的角色，因为他们将自己的微交易货币化模式置于玩家体验之上。

2017年，EA发布了《星球大战：前线2》，玩家要么要玩40个小时才能解锁黑暗维德（Dark Vader）等单一角色，要么采用付费方式直接解锁。该公司对这一操作的回应被称为“Reddit历史上最不受欢迎的评论”，这就揭示了发行商和游戏玩家之间所存在的矛盾。

该公司约30%总收入来源于FIFA Ultimate Team（FUT）盒式战利品物件的销售，该公司公开文件表明了公司在捕捉微交易活动方面的优先地位。EA声称：“所有的道路都通向FUT”，因为“FUT是基石，我们正在尽一切努力推动玩家进入。”
