Creating digital infrastructure for private market transactions. 

Im a lawyer turned entrepreneur striving to build a better global and regulated path for liquidity and information to flow efficiently in private markets leveraging tokenization. 

During my time as a lawyer I have had the privilege of  representing clients like the Reserve Bank of India, the Election commission of India, and large state governments in the Supreme Court of India. 

Area of practice includes blockchain, fin-tech, and constitutional law. 

I have also been an investor and trader in equity, commodities and cryptocurrencies with over a decade of experience in web3.

I have helped consult DAO’s and various web3 protocols in my days as a lawyer. 

Founder and CEO at Rooba.finance.

Eric Gutshall, who ran Hibernia Atlantic sales (five subsea cables) hired me in 2005 as an exclusive sales contractor paid only commissions. By 2011 my recurring sales revenue was $12 million a year and my clients included the world's largest software company, PTTs, and Tier 2 Internet companies.  

I source Layer 1-3 network capacity, edge computing, and network equipment in the wholesale market. I find my clients the best network capacity in terms of pricing, uptime  latency, commercial flexibility, and physical diversity with some expertise in subsea cables. The client gets direct service and contract from network operator. I usually charge no consulting fees to the customer. The carrier pays us for the sale. I represent  PCCW, Tata, EUNetworks, EXA, Bayobab, and others. My approach is based on intimate knowledge of subsea cables, terrestrial fibre optic networks, and the wholesale industry in general. Excellent contacts. 

I am also a contrarian real estate entrepreneur. I own four large Budapest flats purchased during the Great Recession and renovated them under guidance of the great interior designer Judit Kozcoh (linkedin.com/in/judit-koczoh-a1b44a3 ). Guests have included an art director for Blade Runner 2049, the props master for the Alienist, and the scene designer for The Martian. Building a country rental home that meets the Passive House requirements outside Estonia's capitol, Tallinn.

Amazon Deploying Hollow Core Fibre In Its 400G Backbone Network
Amazon's North American fibre optic network depicted below. Its global network consists of nine million kilometers of owned fibre pairs. Amazon spent the last year experimenting with hollow core and is now ready to join Microsoft in long haul deployments. See their blog for more details: https://lnkd.in/dDN9nJ8B. Microsoft has already deployed hollow core fibre in the long haul to connect three AI data centres. It owns the leading hollow core manufacturer and research company, Lumenisity. 

New hollow core designs unveiled in a recent Nature Photonics paper have solved the main obstacle to long haul deployment, namely high attenuation. High attenuation simply means light pulses fade rapidly as they travel through a medium and hence require frequent amplification that drives up capital and operating costs. In contrast, Lumenisity's new hollow core design unveiled in the Nature publication has up to 50% less attenuation than standard fibre. This means it can be incorporated into existing terrestrial long haul networks.

Benefits Of The New Improved Hollow Core Fibre

***Attenuation of .1db or better per kilometer versus .14db for standard commercial solid core fibre. This alone sharply increases repeater hut spans and hence reduces the number required. In turn this means lower construction costs and operating expenses. 

***Latency reduction of 30% due to the faster speed of light through air versus silicon. 

***A 5x to 10x long term bandwidth increase as hollow core fibre can use not only C+L bands, but also the O,E,S, and U bands. These bands will require new amplifier designs as existing erbium doped amplifiers only work well in the C band. 

***Hollow core fibre has little to no chromatic and polar dispersion. So there is less need for expensive forward error correction and other digital signal processing technologies that correct dispersion problems. The bottom line is more robust and cheaper DWDM equipment and transponders. 

***See the breakthrough Nature Photonics article for the full picture: https://lnkd.in/dynyEzBT.

***Next steps include greater production to drive down per unit costs and training field technicians in splicing and handling hollow core.

What We Can Glean From Amazon's Network Map - Part 1
1. Amazon has capacity on both the Echo and Bifrost cables that directly connect Singapore to the States. 
2. Almost every POP with the exception of Brisbane is part of a fully diverse ring. Resiliency is the most important factor in the design of Amazon's wide area network. 
3. Appears that Amazon is using some of those expensive Red Sea bypass routes that traverse Iraq and Turkey. It could have as much as 600Gs on those routes.
4. Appears Amazon is using Juno to connect Osaka to LA. One of the advantages of the Juno cable is that it has an Osaka landing branch. 
5. No capacity on Topaz. Maybe Canada is just not a high enough priority or maybe Amazon cannot get a reasonable price. 
6. Amazon appears to be riding Southern Cross Cable Network or Haiwiki between Sydney and Portland. Given pricing, Haiwiki is a better bet. 
7. My guess is Amazon is using both cables of Southern Cross to land in Portland and also above Los Angeles. 
8. Amazon is using a land link between Hanoi and Ho Chih Minh City. 
9. Amazon is using a cable that reaches Singapore via a Malaysia landing. Must be Bay of Bengal Gateway. Its unique physical diversity as the only cable to connect Singapore to India without landing at Singapore makes it favorite among smart network planners. The Indian landing is Chennai. This again is better than betting everything on Mumbai. 
10. One weakness in Amazon's network is the lack of direct connectivity between the US West Coast and the Western Coast of South America. I understand why this is so. According to Amazon astronomy the universe revolves around North Virginia, but according to modern physics every point in space is the centre of the universe. 🙂 
11. Amazon is definitely on Dunant for the Paris/Northern Virginia arrow. Surprisingly, not on Marea. I do bet Amazon takes some capacity on Anjana. 
12. While Northern Virginia is the key North American hub, Ireland, Marseille, and surprisingly, Milano, are quite important for Europe. 
13. I am proud to say my home town of Tallinn hosts the only Amazon POP in the Baltics. 
14. Africa is a bit mysterious to me. Equiano lands in Lisbon, but the map indicates no Lisbon landings. It may be that South Africa to London is 2Africa. There is a second cable from Lagos to London. It could be WACS or Globe. There is another Capetown cable to Madrid. Again, no Lisbon landing. I am befuddled. Now ACE does land in Spain, but it's a dog. Interestingly enough, Amazon is moving traffic overland between Johannesburg and Nairobi. But there are no reliable and high capacity cables overland to the Mediterranean. Hence I believe Amazon is using the Red Sea, but taking artistic license with its logical map. 
15. The Bahrain to Cairo arrow probably represents SMW6, which is using a terrestrial path between Bahrain and Jeddah to bypass the Red Sea off disintegrating Yemen.
