Ibm blockchain platform technical overview
Learn ibm blockchain platform technical overview it can accelerate network activation and collaborative governance for your multi-organization network. Blockchain is a transformational technology that is helping drive business value across industries by saving time, reducing costs, lowering risks, and enabling new business models. For ibm blockchain platform technical overview, IBM Global Financing is one of the world's largest technology financiers with more thanclients in over 60 countries with 4, partners and suppliers.
IBM's use of blockchain technology has freed up million dollars that was previously, at any time, tied up in transaction disputes. For details regarding this successful ibm blockchain platform technical overview of blockchain, see the video ibm blockchain platform technical overview the right. Collaborators suppliers, consumers, partners, etc. Consider a retail store scenario as a simplified example: A retail store purchasing computer parts logs the purchase order with a supplier while also recording the purchase order and money transferred in the retail store database.
The supplier ships the item, recording that the item has been shipped in the supplier database and recording the collection of money for the good. In this scenario, the supplier and the retail store each have their own data in their own separate databases. When a problem occurs say, the shipped good does not arrivehow does the retail store track down the location of the part? Today, they must rely on separate records to validate what occurred and also navigate through the delivery pipeline to determine where ibm blockchain platform technical overview item is ultimately located.
This manual process is time consuming and error prone. Ibm blockchain platform technical overview is revolutionary in that it allows for a decentralized, immutable ledger that records each transaction. The ledger is decentralized and shared: The members of the network each have a copy of the ledger in our example, the retail store and the supplier have the same copy.
The ledger is also immutable: Each transaction is signed by multiple parties and protected by the chain of block hashes representing the content of each block of data. As a result, if a rogue organization attempts to tamper with the data in the ledger, it is easily discoverable. Blockchain and the Internet of Things explained. In our retail store scenario, the item is picked up by a trucking company, is delivered to a port, is loaded on a ship, arrives at a port, and finally is delivered by truck to the retail store.
When the item arrives at a particular ibm blockchain platform technical overview, that item, the date, and location are recorded in the blockchain ledger. As a result, the ledger now has a detailed record of the date and location of the item as it moves through the delivery pipeline. If ibm blockchain platform technical overview item does not arrive, both the retail store and supplier can look at the ledger, where all the information is recorded. The retail store and supplier can then determine where the item is currently located, because all the arrival points are recorded in the ledger and cannot be deleted or altered.
By having this shared, immutable ledger, companies can drastically reduce the time spent resolving disputes, finding information, and verifying transactions, leading to quicker settlement. Furthermore, costs can be trimmed because a central governing body or arbitrator is eliminated for dispute resolution, and because the ibm blockchain platform technical overview ledger enables the automation of inefficient processes.
Security risks are also reduced due to minimizing collusion and tampering, given the secure and transparent nature of blockchain technology. Different ibm blockchain platform technical overview plans are available to fit different ecosystem needs.
You can migrate from proof-of-concept to pilot to ibm blockchain platform technical overview on a secure, high-performance, and fully scalable network that you can't outgrow. For an easy and economical on-ramp to developing and testing your proof-of-concept apps in a pre-production environment, consider the Starter Plan.
Learn how to get started. The IBM Blockchain Platform is the first commercially available platform to leverage technologies from Hyperledgera ibm blockchain platform technical overview, open source, collaborative effort hosted by The Linux Foundation. IBM is a co-founder and ibm blockchain platform technical overview member of the Hyperledger community, as well as an active technology ibm blockchain platform technical overview to both the Hyperledger Fabric and Hyperledger Composer open source projects.
Both projects are achieving fundamental advancements in the standardization of permissioned blockchains for business use. While IBM has contributed significantly to the Hyperledger Fabric and Hyperledger Composer code bases, the ecosystem of contributors has grown to include developers from startup companies to enterprises.
The IBM Blockchain Platform is the only managed software-as-a-service that supports and guides users through all the required stages for launching a blockchain network: The IBM Blockchain Platform reflects IBM's experience with over clients and multiple active networks operating the longest-running production blockchain network for enterprises. The IBM Blockchain Platform simplifies the development, governance, and operation of a decentralized network across multiple companies or institutions forming a business ecosystem.
It enables all members to quickly achieve the common goal of activating and collaboratively governing their network so they can get on with conducting, innovating, and deriving value from their business transactions. See the Top 6 technical advantages of Hyperledger Fabric for blockchain networks. Hyperledger Fabric is a framework for ibm blockchain platform technical overview ledger solutions on permissioned networks, where the members are known to each other. Its modular architecture allows for a flexible trust model and maximizes performance and scalability while opening the way for supporting desired ibm blockchain platform technical overview membership and cryptography, for example.
Network scalability and performance are optimized because only a small subset of the nodes are required to participate in endorsing transactions, while the chance of failed consensus is reduced because the endorsers and committers participating in transaction processing are limited to those in channels.
Channels, introduced in Hyperledger Fabric v1. Trust is also increased as each chaincode can specify a ibm blockchain platform technical overview set of endorsers and committers that it trusts to do its execution for each particular transaction.
Chaincodealso called a smart contract, is the software that encapsulates the business logic and transactional instructions for creating and modifying assets. With the IBM Blockchain Platform, users with the right permissions can easily install and instantiate chaincode for channels, and see members who are in the channels that they participate in.
Properly authorized users can invoke chaincode, create new channels, and even update a channel's access rights based on the policy of the blockchain network established. Policies requiring consensus within or across organization members or admins can be set and enforced to grant access to channels, instantiate chaincode, invoke chaincode, submit transactions, reconfigure participant organization membership credentials, upgrade chaincode, or even modify existing policies.
Furthermore, properly authorized auditors can also easily audit the content of certain transactions associated with an asset transfer to ensure the business logic was properly applied. Note that the chaincode hash is submitted to the blockchain, so endorsers are bound to what they have executed. Chaincode runs in a secure container associated with any peer that needs to interact with it. Chaincode is first installed on a peer's filesystem for a peer that will participate in exchanging assets.
Chaincode is then instantiated on a specific channel that contains a list of members. Each channel represents a subset of members that are authorized to see the data for the chaincode instantiated on that channel.
The trust model associated with each chaincode's execution can be based on business logic itself by executing on only the set of endorsers and committers versus executing across all nodes. If you are not on a channel, you can't see the data in it. Multiple channels can be set up with a list of permissioned members.
Ibm blockchain platform technical overview the installation and instantiation of chaincode, as well as member participation in channels, is made easier through the governance and user interface of the IBM Blockchain Platform.
Hyperledger Fabric also allows application layer encryption, while access to decryption keys can be restricted to the few properly authorized endorsers that the application trusts. This capability demonstrates how the business logic trust model helps to ensure confidentiality of the keys. Let's look at specific, unique ways the IBM Blockchain Platform simplifies development, governance, and operation to accelerate network activation and collaborative governance throughout the network.
For a fast and economical start to piloting your own blockchain solution in a pre-production network, try the IBM Blockchain Platform Starter Plan. Blockchain networks are usually sparked by innovative business ideas, which application developers translate into working code.

The Starter Plan offers the same experience as the Enterprise plans, so there's no learning curve when migrating to a production network.
Develop toolset based on the Hyperledger Composer development toolsetall developers need to know is JavaScript, and they are minutes away from having a running blockchain network using Hyperledger Fabric.
This toolset's unique approach to software design allows a business person and developer to code collaboratively, ensuring the rapid delivery and full fidelity of a business concept.
Developers can quickly model a business network by specifying its assets whether tangible or intangible goods, services, or property ; the types ibm blockchain platform technical overview transactionsas well rules that govern transactions that will interact with assets perhaps buying or selling an asset ; and the participants who interact with the assets and transactions that may have a unique identity.
With three easy concepts of assets, transactions, and participants, a developer can quickly create ibm blockchain platform technical overview true business application.
Developers can use queries to return data about the world state. For example, an asset or participant can be selected according certain criteria, and actions can then be performed on a set of results. To make development even easier, the toolset integrates with most JavaScript frameworks and allows a developer to complete a blockchain project including a user interface angular. The toolset has pre-built chaincode and extensible templates for key industry use cases.

The challenge of deciding how to offer all participating members some control in a blockchain network with a shared ledger — while preventing any one member from having exclusive control — is often overlooked and underestimated.
Governing an operational blockchain network across a group of members can take significant coordination, time, and effort. The ultimate goals of proper network governance are to ensure regulatory compliance, remove the uncertainly and risk of applying business rules encoded in smart contracts, or chaincodeprovide privacy and confidentiality for different classes of transactions protected in channelsand prevent bad actors from joining the network.
The ecosystem has to overcome the fact that it is only as strong as the weakest member, as fast as the slowest member, as rich as ibm blockchain platform technical overview poorest member who may be struggling to find fundingas secure as the most insecure member, and as smart as their least informed member. You might imagine that bootstrapping an enterprise-grade blockchain network would be a complex process, requiring a lot of information and coordination to set up the hardware and software.
And you'd be right! Setting up a network with all the certificates, the members of the network, and the governance ibm blockchain platform technical overview is quite complex, but the IBM Blockchain Platform makes it easy. In a few minutes, you can activate a blockchain networkinvite participants to join the network, add new channels, and set up the operating rules for the network.
Activation tools allow you to start your network small and grow elastically as more members are needed. The IBM Blockchain Platform also provides governance tooling, which helps members to democratically operate a ibm blockchain platform technical overview network. As an example of a governance policy, members ibm blockchain platform technical overview want to set rules to determine how members join the network. Do all ibm blockchain platform technical overview need to agree to have another member join?
Network governance is embodied in governance policies like these. A policy editor is available within the IBM Blockchain Platform to help set the democratic policies for numerous lifecycle tasks of a blockchain network. Based on this governance tooling and policies for who has appropriate access, resource screens are provided to help manage resources for the Certificate Authority, the peers, and ordering service.
As an example, on the resource screens, those who have permission can access logs that can be useful in debugging blockchain applications on particular channels. Also, the policy editor is a multi-party workflow tool that provides features such as the member activities panel, integrated notifications, and secure signature collection for policy voting.
Once you have activated your network using the IBM Blockchain Platform, you can deploy and operate your decentralized network with a production-ready, security-hardened, always-on service that is optimized for performance.
Its ultra-high-security environment includes many hardware, firmware, and software security features designed for scalability, resiliency, and availability.
