FAQs

Question 1. What is the difference between a permissioned and a permissionless blockchain?

Permissioned and permissionless blockchains are two different types of blockchain networks based on their accessibility and participation requirements.

1. Permissioned Blockchain- A permissioned blockchain, also known as a private or enterprise blockchain, restricts access to the blockchain network to a select group of participants who have been granted permission. Permissioned blockchains are typically used within organizations or consortia where participants are known and trusted entities. Access to the blockchain network is controlled through a predetermined set of rules and protocols, and participants may require authorization or approval to join and participate in the network.
   
   Key characteristics of permissioned blockchains include:

   • Restricted Access- Only approved participants can join the blockchain network and perform transactions or participate in the consensus process.
   • Centralized Governance- Permissioned blockchains often have a central entity or group that controls the decision-making process and sets the rules for the network.
   • Higher Efficiency- Permissioned blockchains may have faster transaction times and lower transaction fees compared to permissionless blockchains, as they do not require extensive consensus mechanisms.
   • Lower Decentralization- Permissioned blockchains may have a lower degree of decentralization compared to permissionless blockchains, as decision-making and governance are often concentrated in the hands of a few entities.

2. Permissionless Blockchain- A permissionless blockchain, also known as a public or open blockchain, allows anyone to join the network and participate without requiring any authorization or approval. Participants in a permissionless blockchain have equal access to the network and can perform transactions, participate in the consensus process, and validate transactions. Examples of permissionless blockchains include Bitcoin and Ethereum.
   
   Key characteristics of permissionless blockchains include:

   • Open Access- Anyone can join the blockchain network and participate without needing any authorization or approval.
   • Decentralized Governance- Decision-making and governance in permissionless blockchains are distributed across the network, with no single entity having control.
   • Higher Transparency- Permissionless blockchains are typically more transparent, as all transactions and activities on the blockchain are publicly visible and verifiable.
   • Lower Efficiency- Permissionless blockchains may have slower transaction times and higher transaction fees compared to permissioned blockchains, as they often require extensive consensus mechanisms to maintain integrity and security.

In summary, the main difference between permissioned and permissionless blockchains is the accessibility and participation requirements. Permissioned blockchains restrict access to a select group of participants, while permissionless blockchains allow anyone to join and participate. Permissioned blockchains often have centralized governance, higher efficiency, and lower decentralization, while permissionless blockchains have decentralized governance, higher transparency, and lower efficiency.

Question 2. What are the differences between the many different types of "proof-of-stake" protocols?

Proof-of-stake (PoS) is a consensus mechanism used in blockchain networks to validate transactions and secure the network. There are several different types of PoS protocols that vary in their design, approach, and implementation. Here are some of the key differences among various PoS protocols:

• Pure PoS- In a pure PoS protocol, validators (also known as stakeholders) create new blocks and validate transactions based on the amount of cryptocurrency they hold and "stake" in the network. The stake typically determines the probability of a validator being selected to create a block, with higher stakes leading to higher chances of block creation. Examples of pure PoS protocols include Tezos and Cardano.

• Delegated PoS- In a delegated PoS (DPoS) protocol, a limited number of validators (often referred to as "delegates" or "witnesses") are elected or appointed to create blocks and validate transactions on behalf of the network. DPoS protocols rely on a smaller set of trusted validators, which can result in faster transaction times compared to other PoS protocols. Examples of DPoS protocols include EOS and Lisk.

• Bonded PoS- In a bonded PoS (BPoS) protocol, validators are required to "bond" or lock up a certain amount of cryptocurrency as collateral to participate in block creation and transaction validation. If a validator behaves maliciously or violates the network's rules, their bonded cryptocurrency can be forfeited as a penalty. Examples of BPoS protocols include Polkadot and Cosmos.

Question 3. What is forking?

Forking occurs when a blockchain splits into two or more separate branches. Eventually, only one branch will survive. In the interim, a fork causes significant uncertainty. If a payment made to you appears in only one of the branches you do not know if you have been paid or not, because your payment may end up in a non-surviving branch. There are several types of forking:

1. Hard Forking - A hard fork refers to a permanent split in the blockchain network where the original chain and the forked chain become independent and separate from each other. This results in two or more separate blockchains with different rules, features, and possibly different cryptocurrencies.

   A hard fork can occur in Algorand if there is a significant disagreement among stakeholders on the protocol upgrades or changes, and the consensus cannot be reached through the normal upgrade process using the Pure Proof of Stake (PPoS) consensus mechanism. In such cases, a portion of the stakeholders may decide to create a new chain with a different set of rules, resulting in a hard fork.

   In a hard fork, the new chain will typically have its own governance, consensus rules, and possibly its own native cryptocurrency. This can lead to a divergence in the blockchain's transaction history, as new transactions and blocks may only be valid on the forked chain and not on the original chain, and vice versa.

2. Soft Forking - a soft fork refers to a temporary or reversible split in the network that does not result in a permanent divergence of the blockchain. Soft forks are typically introduced to implement protocol upgrades or changes that are backward compatible, meaning that the new rules are compatible with the existing rules, and nodes that do not upgrade can still participate in the network.

   The new rules are enforced by a majority of the network's validators, while nodes that have not upgraded can still continue to operate based on the old rules. This means that transactions and blocks that are valid according to the new rules will also be valid according to the old rules, and both types of nodes can still communicate and participate in the same network.

   Soft forks are typically used in situations where there is a need to implement changes to the blockchain's protocol or consensus rules while maintaining backward compatibility with existing nodes and avoiding disruptions to the network's continuity. They are considered less disruptive than hard forks, as they do not result in the creation of separate chains or require users to upgrade their software, but they may still require coordination and consensus among stakeholders to ensure a smooth implementation.

Question 4. For the Algorand network, what does it mean for an account to be offline or online?

The terms "offline" and "online" typically refer to the status of an account in relation to its participation in the consensus process and ability to submit transactions to the network.

1. Offline Account
   An account is considered "offline" when it does not have an active connection to the Algorand network. This means that the account's associated node, which is responsible for validating transactions and participating in the consensus process, is not connected to the network and therefore unable to actively participate in block validation or transaction processing. An offline account cannot send or receive transactions, and its holdings and status on the blockchain may not be updated until it comes back online.

2. Online Account
   An account is considered "online" when it has an active connection to the Algorand network. This means that the account's associated node is connected to the network and actively participates in the consensus process, validating transactions, and processing blocks. An online account can send and receive transactions, participate in the consensus process, and its holdings and status on the blockchain are updated in real-time.

It's important to note that being offline or online does not affect the security of an account or its holdings on the Algorand blockchain. Account security is primarily determined by the private key associated with the account, which is used to sign transactions and authorize changes to the account's state. Whether an account is online or offline simply determines its ability to actively participate in the consensus process and submit transactions to the network at a given moment.

Question 5. What is a Multi-Sig account?

A multi-signature (multi-sig) account in the Algorand blockchain refers to an account that requires multiple signatures from different parties to authorize a transaction. It is a form of account control mechanism that enhances security and enables more complex transaction authorization workflows.

In a multi-sig account, the account owner can specify a certain number of signatures required to approve a transaction. For example, a 2-of-3 multi-sig account would require two out of three specified signatures to authorize a transaction. This means that at least two out of the three authorized parties must sign the transaction for it to be valid.

Multi-sig accounts in Algorand can be used in various scenarios where additional authorization is needed for transaction approvals. This can include joint accounts where multiple parties need to approve transactions, corporate accounts where multiple executives or board members need to sign off on transactions, or escrow accounts where a third-party mediator is involved in the transaction process.

The use of multi-sig accounts adds an extra layer of security to Algorand transactions, as it reduces the risk of unauthorized or fraudulent transactions. It also provides flexibility in transaction authorization workflows, allowing for customizable and more complex approval processes.
