Blockchain is, without a doubt, one of the subjects that the market is talking about a lot these days, not only because of the Bitcoin, but for the various possible uses of technology. Have you read our explanation of the subject ? 1a653z
This is a topic that has personally attracted me a lot because I believe there is a huge corporate market that can benefit. And when we talk about corporate, IBM is already working hard in this area, and we got an interview with Luiz Jeronimo, Technical Lead for Blockchain at IBM Brazil.

What is the technology known as Blockchain and why has it been attracting so much attention in the most diverse segments? 3j6734
Blockchain appeared 7/8 years ago in a whitepaper posted by Satoshi Nakamoto proposing the creation of a person-to-person (P2P) financial system for exchanging digital money. The most well-known currency to use the technology is the Bitcoin, and today there is a very agitated and consolidated market.
Soon after the publication of paper the market began to analyze the technology that was being used, and then they realized that the system solved a problem of exchanging assets without intermediaries (systems without clearing).
For example, the methodology uses techniques to ensure that an asset is not spent twice. In the case of a banknote, you cannot use the same banknote for two different purchases. With these guarantees, companies realized that it would be possible to use the technology in different markets where assets (physical or not) through different people. See below for other usage examples.
tradefinance 2t4p1
A tradefinance is using blockchain in the sale of products that involve a letter of credit as a guarantee for a commercial operation. That is, a letter of credit is issued by one bank against another bank that will enforce it against a final beneficiary.
Often used when an importer needs to guarantee payment to the exporter. The old model has some inefficiencies, common clause, letter must be settled when the product arrives at the port of destination, settlement can take days, at the end of the process the exporter can take weeks to receive.
European bank consortium 113h19
Seven European banks have come together and formed a consortium to help small and medium-sized companies that have difficulty obtaining export credit. The UBS bank, together with IBM, developed a solution for these cases, which is already ed by 5 other European banks.
Everledger 2mb4g
A startup Everledger, from London, developed a system for traceability and certification of the origin of diamonds. In 2015, the company received a contribution from the bank Barclays.
There are several problems and risks in diamond extraction, such as slave labor or origin of countries in wars. With the company's technology, it is possible to track and guarantee the entire chain, from extraction to the sale of the final product, so the consumer can know the origin of the product.
Walmart 1r3h1
Walmart experienced some food contamination problems of products in China. They then developed a solution that allows knowing the entire history of a product that is on the shelf to be sold. It receives a QR code that allows the customer to consult all the information, from production, vaccines, transport, hygiene certificates, temperature standards in transport. And, in addition, when the product goes to the cashier, all the information is checked and if there is a problem in the chain, the sale is barred.
Are there difficulties in adopting the technology? Which sectors and services can benefit? 3bp38
There is no limitation, the solutions can be applied to any industry. But in general, solutions are developed when there are external partners, other companies involved. Solutions are rarely developed to solve only internal problems of companies.
Just like the internet, which had no standard in its beginnings and standards were being created by W3C, Blockchain it also suffers from a lack of standardization, as each company uses the base technology and develops its own solution. This issue must be resolved in the short term by the companies.
IBM believes that technology has to be open source, so they are in the consortium hyper ledger fabric to build a code open source for use as a market standard.
Blockchain is a set of technologies, a structural solution that enables the creation of disruptive and innovative business models. Which ones will survive? Only time will tell. It is still a maturing solution, because of that the adoption still takes into the lack of skill, lack of knowledge to know how and where to adopt.
We are currently at a time of many ideas, but many things will not go ahead because there is no guarantee of adherence to models and ideas. Companies are ing in consortia to assemble solutions together.
Is the system really foolproof? How to ensure that information ed in a block is not tampered with? 49s5k
The system gathers a group of transactions and assembles a block. So one hash (signature) of that block is generated and any change to the previous information invalidates the block. O hash that is generated takes into the current block and also the hash from the previous block.
To defraud, you would have to recreate all previous steps in the chain, which is considered unfeasible.
Is there some kind of control? A kind of Blockchain regulatory body? 6x3271
About blockchain in itself, does not exist, just as it does not exist for cryptocurrencies, such as the Bitcoin. And it's even open source. But the technology can be used in projects where there is a regulator, which in many cases is even welcome.
If a company needs to audit companies in a sector, having the regulator helps in the process, as the inspection is much faster and more effective. Companies operating in regulated areas often need to respond to the regulator, and the use of the blockchain facilitates the inspection process, making the process faster and more effective.
Each “condominium” has its rules of participation, criteria, definition of who can participate, enter and leave. Compared to residential condominiums, each resident has their own apartment, but there are common areas that need caretakers for operation and someone to syndicate on the whole. You own yours, but there is a common part that needs to be governed among the participants.
IBM is already considered a world leader in Blockchain, how do you see the market globally and in Brazil? Do you have any usage examples? 1qy4p
Both abroad and here, it is one of the important strategies for IBM, along with congnitigo e Cloud. We already have more than 400 projects in the world in different industries.
In Brazil there is a space called Garage 1157 with some proofs of concept, some of which are already on their way to production. The space is intended for use by companies to implement new ideas. In general, between 6 and 8 weeks is the time required for companies to develop a proof of concept using IBM's agile methods.
