Public Blockchain with security features built in.
Lamport digital signature algorithm. Claims to be resistant to quantum computer attacks.
Customized P2P network with data storage encryption, location transparency, source nontraceability
Merkle Patricia Trie data structure
Although the hash algorithm built into Bitcoin and Ethereum is secure with todays technology from brute force attacks, quantum computing may support enough computational power to compromise these algorithm.
|
"Block Security Protocol" (BSP)
Employs a BSP to implement the signature function on each data bock during PoA cosnensus. Only the blocks with authorized signatures can be mined and accepted.
|
No data encryption or channel partition and is public.
Merkle Patricia Trie Data structure
Data and contracts in Ethereum are encoded but not encrypted and all data is public - therefore all sensitive data should be encrypted locally and hash stored to prove authenticity.
|
|
|
Permissionless
|
Permissioned Aspects
Only permissioned parties can view the raw transactional data stored in the public blockchain. To all others, it will be hashed and secured.
Anyone can become a node, but there is a hard cap of 101 Authority Nodes. It requires a great deal of transparency and public capital to become a node.
|
Permissionless
Anyone can download the protocol and validate transactions making it less secure
|
|
|
Based on zero knowledge proof. Hides the send, receipt address and transfer amount.
Similar in function to the zk-SNARK feature Ethereum added during their Metropolis release.
|
Yes
Transaction Data Privacy Protocol (TxDP): Ensures privacy of transaction data.
|
Limited (zk-SNARKs, Ring signatures)
Privacy in this public permissionless network has been limited. Since the Metropolis hard fork, it became possible to integrate more cryptographic operations in smart contracts - two kinds of technologies are implemented: zk-SNARKs and Ring Signatures.
‘Zero-knowledge’ proofs allow one party (the prover) to prove to another (the verifier) that a statement is true, without revealing any information beyond the validity of the statement itself.
Ring Signatures are a cryptographic technology first introduced in 2001. It enables any member of a group of users to perform a digital signature, that can be proven to be made by a member of this group, while it is impossible to determine by which member of the group.

Fast Paxos PoS variant.
The consensus of TRON adopts a three-step strategy.
1. Kafka-based technology system: implement a centralized consensus algorithm.
2. Raft-based distributed consensus mechanism: realize the centralized and distributed leapfrogging. Improves network function/distribution and lays the foundation for distribution with no logical center.
3. Consensus mechanism of Proof of Stake and realize the Byzantine Fault Tolerant Consensus.
|
Proof of Authority
Consists of 101 Authority Nodes that are controlled by separate, self-interested entities. Due to the variety of companies, this will secure the network and ensure a trustless environment. PoA allows for a higher number of TPS than PoW and PoS, meaning VeChain can support up to 10,000 TPS.
|
PoW & PoS
Proof of work (PoW) + PoS-based public blockchains in Ethereums upcoming Casper implementation. Opposed to the PoW consensus protocol, the PoS protocol achieves consensus through stakers, sometimes referred to as minters who “stake” their coins by locking them down in specialized wallets. With stakers at work, mining will become redundant, meaning the Ethereum network post-Casper will rely on stakers and staking pools instead of miners for its operability.

Public with Private Forks
Ethereum can be a public or private blockchain. The Ethereum Main network is obviously a public blockchain, but with increasing enterprise-focus a number of projects and consortiums (Ethereum Aliiance) have been launched that develop private blockchains (e.g. Quorum)

Similar to Ethereum:
Generic, with DApp and Smart Contract support for wider applications
It is not modularity that stands out but the provision of a generic platform suitable for various types of transactions and applications
|
Yes
VeChain exists as a platform to be developed on. Meaning the core features and services can be applied in a number of industries. Some utilizing IoT, some just using the consensus mechanism.

Generic, with DApp and Smart Contract support for wider applications
For Ethereum it is not modularity that stands out but the provision of a generic platform suitable for various types of transactions and applications

|
Currently supports 15 TPS as it is on the Ethereum platform. Will be able to support up to 1000 TPS once main net launches
Scalability is a core feature for TRON. They want to be able to support large commercial projects, while minimizing transactions fees and time.
|
50 - 10,000 TPS
50 TPS is currently the maximum. Once VeChain moves to thier mainnet, they plan to scale their TPS to 10,000. This will enable Enterprise level support for financial and sensor data.

limited by PoW
currently supports a maximum of 15 TPS
designed for public networks, limited by Proof of Work (PoW) consensus
