The Problems of Blockchain 1.0

Understanding the main problems of blockchain 1.0

If we look back into Blockchain 1.0, Blockchain 1.0 is introduced by Bitcoin, created the basic structure for decentralized transactions, and presented the general concept of a distributed ledger. However, there are some problems and limitations of Blockchain 1.0. They are

 

Scalability

One of the critical problems with Blockchain 1.0 is scalability. In the original Bitcoin blockchain, transaction processing capacity is limited. This can make the outcomes of slow transaction periods and high fees during periods of high network demand. General scalability challenges are the block size limitation and the consensus mechanism based on proof-of-work (PoW).

 

Energy Consumption

Blockchain 1.0 networks based on PoW consensus will consume a substantial amount of energy. The mining process in Bitcoin will need some computational power and electricity which will result in negative effects on the environment and high operating fees.

 

Lack of Flexibility

Blockchain 1.0 networks normally have limited work and functionality beyond the core transactional layer. During the period of Bitcoin serving as a digital currency, it does not contribute the flexibility to assist complex smart contracts and decentralized applications (dApps) which can be seen in future blockchain models.

 

Interoperability

  Blockchain 1.0 networks carry out the process in isolation which does not have efficient interoperability with another blockchain system. The lack of being able to communicate and share data easily will decrease the potential for transactions and collaborations.

 

Privacy Concerns

  Blockchain 1.0 provides pseudonymity however it cannot really provide comprehensive privacy and confidentiality. Bitcoin transactions are usually transparent and trackable, making it difficult to protect important information.

 

Governance 

Blockchain 1.0 does not consist of effective governance mechanisms and systems. Decision-making procedures, protocol upgrades, and consensus alterations need broad consensus between network participants which might be a slow process. This governance problem can point out the capability to improve and enhance the blockchain to satisfy the needs.

 

User Experience

For non-technical users, Blockchain 1.0 is complex and difficult to apply. The procedure of creating wallets, managing private keys, and acknowledging transaction details can cause quite a challenge to users.

 

The Problems of Blockchain 2.0

Understanding the main problems of blockchain 2.0

Blockchain 2.0 announced several improvements over Blockchain 1.0 with smart contracts and decentralized applications (dApps) and it can be represented by Ethereum. However, it still has some challenges. They are

 

Scalability

Same to Blockchain 1.0, the updated one, Blockchain 2.0 still has major concerns in scalability. Due to the fact that there are more decentralized applications and transactions on the Ethereum network, it can result in congestion and increased fees. The limitations and boundaries in the efficiency of transaction procedure and scalability delay the smooth process of dApps.

 

Security Concerns

Smart contracts which are one of the main features of Blockchain 2.0, produced a new attack surface. Programming carelessness in smart contracts can result in costly security attacks and exploits. The infamous case of the DAO (Decentralized Autonomous Organization) cyber attack in 2016 pointed out the risks due to smart contract vulnerabilities.

 

Upgradeability

Blockchain 2.0 networks have some challenges in the upgrade and modification of protocols. Carrying out protocols to the underlying blockchain needs coordination and consensus among network participants. This procedure can become a slow process and can result in chain splits (hard forks) if disagreements between shareholders have occurred.

 

Environmental Factor 

Like the original 1.0, many blockchains 2.0 still depend on energy-intensive consensus mechanisms, such as proof-of-work (PoW). This usage can lead to impacts in the environment due to the increasing usage of blockchains.

 

Interoperability

Blockchain 2.0 has more developments in interoperability than Blockchain 1.0 however accomplishing complete interoperability among various blockchain networks is still a problem. Integrating and sharing information among different blockchains requires standardized procedures and an efficient communication system.

 

Governance

Governance in Blockchain 2.0 networks is still a complex case and decentralized decision-making procedures can occur challenges. Protocols for protocol improvements or alterations need consensus between users and obtaining widespread agreement can take several times.

 

User Experience

Blockchain 2.0 networks usually need users to have good technical knowledge in interacting with dApps and in management with cryptocurrency wallets.

 

Blockchain 3.0 Scalability

 

The main goal of Blockchain 3.0 is to solve the scalability issues that are encountered in earlier blockchain iterations. Sharding, side chains, and off-chain transactions are just a few of the scaling options that are included in Blockchain 3.0.

 

Sharding: Sharding is the division of the blockchain into smaller pieces known as shards. A subset of transactions is processed by each shard, enabling parallel processing and higher performance.

 

Side Chains: Side chains are distinct blockchains linked to the primary blockchain. They are able to independently process transactions, which eases congestion on the main chain and enhances scalability.

 

Off-Chain Transactions: Off-chain transactions use state channels or payment channels to take place apart from the main blockchain. With the use of these channels, parties can carry out a variety of transactions privately and settle them on the primary chain afterward, which speeds up transactions and eases congestion.

 

Blockchain 3.0 Privacy

 

Blockchain 3.0 seeks to increase privacy and confidentiality while maintaining the blockchain's transparency and integrity.

Proofs of Zero Knowledge: Users can demonstrate the veracity of information using zero-knowledge proofs without disclosing the underlying data. By guaranteeing that private information is hidden while validating transactions or carrying out smart contracts, this method promotes privacy.

Ring Signatures: By hiding the sender's identity, ring signatures allow for anonymous transactions. They enable a user to sign a transaction with a variety of potential signers, making it difficult to pinpoint the original signer.

 

Blockchain 3.0 Interoperability

Blockchain 3.0 places a strong emphasis on interoperability, allowing for easy data sharing and communication between various blockchain networks. Its objectives include the creation of standards, protocols, and cross-chain communication systems. Through this interoperability, assets and data may be moved between various blockchains, creating new opportunities for collaboration and integration.

Atomic Swaps: Without the use of middlemen, atomic swaps allow for direct peer-to-peer asset trades between various blockchains. It guarantees secure and trustless transactions between various cryptocurrencies or tokens.

Cross-Chain Smart Contracts: Smart contracts that span multiple blockchains can now be carried out in Blockchain 3.0. Complex interactions and cooperation between decentralized applications (dApps) running on several blockchains can be possible through this functionality of Blockchain 3.0.

 

Blockchain 3.0 Governance

Blockchain 3.0 investigates alternative consensus and governance models to enhance network performance and decision-making to be better than previous models.

Proof-of-Stake (PoS): This consensus method selects validators to add new blocks based on their ownership or stake in the cryptocurrency. It improves scalability and uses less energy than conventional proof-of-work (PoW).

Delegated Proof-of-Stake (DPoS): This is a variation of Proof-of-Stake (PoS) in which participants choose a small number of delegates to approve transactions and build new blocks. Faster block confirmation and greater scalability become possible by DPoS.
