Baidu Launches Plug and Play Blockchain Engine (BBE) platform Dapps
Chinese search giant Baidu has launched a blockchain platform aimed to simplify commercial deployment of decentralized apps, or dapps.
Officially announced by Baidu Cloud on Thursday, the Baidu Blockchain Engine (BBE) platform is touted as a kind of operating system allowing developers to produce blockchain applications “just like mobile apps,” and get around the storage and computing “bottlenecks” that are holding up blockchain’s potential.
BBE is built on what the company calls the ABC (AI, Big Data, cloud computing) technology stack, allowing customers to explore and develop ways to commercialize blockchain tech.
Hosted on Baidu’s “intelligent” cloud platform, the system uses a modular blockchain framework to provide developers with a multi-chain system including smart contract templates, dapp templates and other...
TRON has 50+ dApps, reaching 100M transactions in 173 Days - Justin Sun
Justin Sun - Founder & CEO - Tron Foundation | Facebook | Twitter | LinkedIn
On Thursday, Justin Sun, the founder of TRON, said that the network supports more than 50 decentralized applications (dApps) and is on track to reach 80 dApps in the short-term.
#TRON now has more than 50+ Dapps. 80+ we are coming! #TRX $TRX
— Justin Sun (@justinsuntron) December 21, 2018
The statement of Sun follows a major milestone achieved by the blockchain network earlier this month, achieving 100 million transactions in 173 days, averaging 578,034 transaction per day.
Usage of TRON DApps
In August, Martin Köppelmann, the founder of Ethereum-based prediction market platform Gnosis.ph, said that an important statistic to reference in measuring the rate of growth of a smart contract protocol is the usage of dApps and the number of dApps that interact with each other.
Köppelmann said:
The numbers we care about is the usage of decentralized applications. And as a next step, the number to look out for is DAPPs that seemlessly interact with each other and draw a benefit from being on the same platform. As a side effect, ultimately the price of ETH will then be a function of the demand for the use of applications in this reliable, open, and interlinked environment.
Like Ethereum, TRON is a smart contract protocol and its value comes from its ecosystem of...
EOS blockchain deep dive
EOS is a blockchain-based development platform designed for building decentralized applications (dApps). Developers can write and deploy smart contracts that power dApps and decentralized autonomous organizations (DAOs).
The platform has a native token with the ticker EOS. EOS tokens were first released as an ERC20 token on the Ethereum blockchain, but a main-net token swap occurred after EOS Version 1.0 was deployed in June 2018.
EOS is often referred to as a decentralized operating system, where holding tokens represents a proportional share in the network bandwidth, storage, and computational resources. DApp developers must stake a certain number of tokens (called RAM) to cover the resources used by their DApp, but they receive those tokens back if the DApp is taken down.
Because of this staking model, users can interact with and use dApps for free. There are also no transaction fees on the EOS network, and block producers earn rewards from newly minted tokens.
EOS was developed and launched by the software company Block.one, who released the software as free and open source. Block.one built the EOS platform to incorporate 3 major features: scalability, flexibility, and usability.
It aims to be scalable by supporting thousands of commercial scale dApps, facilitating inter-blockchain communication, and separating authentication from execution.
It aims to be flexible through the ability to freeze and fix faulty or bug-laced dApps and incorporating generalized role-based permissions.
It also aims to incorporate usability through a web toolkit for interface development, self-describing interfaces, and a declarative permission scheme.
The EOS blockchain uses a Delegated Proof of Stake (DPoS) consensus mechanism with 21 block validators and integrated Byzantine fault tolerance. Delegated Proof of Stake is a consensus mechanism where blocks are validated by a pre-selected group of nodes and it allows for high transaction throughput.
Byzantine fault tolerance is the ability of a network to handle situations where nodes go down or malicious nodes broadcast faulty information. EOS is theoretically Byzantine fault tolerant because 15 out of the 21 block producers are required to confirm a transaction (a 2/3 majority).
For a more detailed discussion on Byzantine fault tolerance and the reason a 2/3 majority is important, refer to our Practical Byzantine Fault Tolerance article.
EOS transactions are typically confirmed within 1 second with a 99.9% certainty, as a new block is created every 0.5 seconds. Dan Larimer stated in an April 2018 blog post that EOS can theoretically support over 1,000 transactions per second and aims to scale to 6-8,000 transactions per second in the future.
EOS also implements a mechanism called Transaction as Proof of Stake (TaPoS), where every transaction must include part of the hash of a recent block header. TaPoS makes it difficult to forge counterfeit chains considering the counterfeit chain would not be able to migrate transactions from the legitimate chain.
- DPoS consensus mechanism: See above section.
- Parallel processing: The ability to do things in parallel on the EOS network allows for faster transaction speeds and more scalability. This is planned for implementation in future versions of EOS.
- Network flexibility: If a DApp is faulty and contains a critical bug, the elected block producers can freeze it until the issue is resolved.
- High transaction throughput: EOS can theoretically support over 1,000 transactions per second with hopes that the platform can scale even higher.
- Ownership model: Owning EOS tokens represents a proportional share of the network resources like bandwidth, storage, and processing power. Developers must prove they hold a sufficient number of tokens to create DApps on the EOS blockchain.
- No transaction fees: Sending EOS tokens to another user or using them for a DApp requires no fee.
- EOS Constitution: The Constitution is a multi-party contract entered into by members of the EOS ecosystem by virtue of their use of the platform. The Constitution has 18 articles that outline the rules and user rights governing the EOS blockchain.

Projects can receive more information about EOS VC and find an application link here: https://vc.eos.io/about-eos-vc/
There is no updated roadmap for the future technical development of EOS.
The EOS blockchain has a native token called EOS. As of December 7, 2018, the total supply is 1,006,245,120 EOS and the circulating supply is 906,245,118 EOS.
EOS tokens represent a share in the platform’s resources – this includes bandwidth, storage capacity, and processing power. Developers who wish to build dApps that run on the EOS blockchain must prove they hold a certain number of tokens and then stake those tokens to deploy the DApp.
Application developers must stake tokens to cover the nominal cost of account creation to sign up new users for their DApp. In addition, they must stake tokens for any storage, CPU power, or bandwidth used by the user. If the developer takes the DApp down, they receive their staked tokens back.
Developers can refer to the EOS Resource Center for up-to-date staking cost calculations. Baseline costs as of December 7, 2018 are outlined...
More than just an interoperability project – AION – FastVM Blockchain
In the Crusher of the Month series, we will write about a coin/token that we have the most conviction in each month. The time frame will be around 1 month, or until we publish the next Crusher of the Month. In October 2018, our Crusher of the Month is AION.
More Than Just an Interoperability Project
Most people know AION as a project focusing on interoperability, but the AION team is also hard at work to make sure the AION root chain will have usage.
In addition to create new blockchains, monetize inter-chain bridges, run cross-chain decentralized applications, AION coins are also the fuel used to secure the overall network. We believe that the market is discounting the potential usage the AION blockchain will have for running decentralized applications (dApps) and smart contracts.
AION has built a lot of tools for developers to build on the AION blockchain. After token swap is completed in November 2018, developers can deploy smart contract or migrate dApps from Ethereum to the AION root chain. CEO of AION, Matthew Spoke, mentioned that it is a 5-minute effort to port existing Ethereum dApps to AION.
The Aion FastVM is a modified Ethereum Virtual Machine (EVM), and Aion virtual machine (AVM) is a performant, lightweight, and stable virtual machine that leverages key characteristics of the Java Virtual Machine. Solidity apps will be supported, but there will also be a new option for running apps in a Java language.
