Lightening Talks were 5 minute introductions to various concepts, products and service being discussed or showcased at the conference. Most, if not all of the lightening talks were followed up with a workshop after so more people could understand the concept and technology behind the product or service.
Jae Kwon (@jaekwon; jae [at] tendermint [dot] com), Tendermint: his product creates a better solution to consensus for services such a Bitcoin.
“With Tendermint TMSP, you can write smart-contracts in any programming language. Leverage existing codebases, workflows, and development ecosystems to build complex & production-quality applications.” They are working on an Apache webserver for WordPress.
GnuClear is a new architecture for Blockchain scaling. It is built on top of Tendermint. GnuClear (I think) is not very good at inter-Blockchain communication, especially for proof of work. Shard1 and Shard2 communicate through a hub. They are mostly interested in money.
- pegging to other cryptocurrencies
- Ethereum scaling
- Multi-application integration
- network partition migration
- federated name resolution system
- Can have own governance system with own rules
It requires its own distribution system
- identified entities
GnuClear Governance is interesting. They do not just have Yay or Nay voting. You lose something if you abstain or vote no. The loss depends on other voters and what the issue is.
Michael Grube, FreeNet
FreeNet is a decentralized distributed censorship resistant datastore
It can transmit data securely
The communication system withing Freenet is not very robust. They use IRL, and FB-like system, etc.
- Publish content
- Publish and turn off computer without people losing access
Nerdagedon is a list of FreeSites
Sone (sp??) is an FB clone
There is a vibrant community of developers who have developed
- GitHub sites
It uses 3 kinds of keys
- CHK – content hashkey share
- USK – updatable subspace key
- SSK – signed subspace key (contributor with a key)
There is content moderation
- I don’t know if filtering is also part of it.
- They use Web of Trust, which mostly works for them.
They only have a primitive search function, which uses webcrawlers and allows users to search on a keyword.
- configure routing bases on reputation
- people sharing files and developers using it now
I still get the impression that moving data is morning important that the data itself and finding information again later.
Muneeb Ali, Blockstack (@muneeb)
Users own their identity with a private key
naming is separate from identity
You pay for your own storage.
They also have a GitHub.
Devon Read, Alexandria
This presentation was one of the best and most understandable that I saw, but it made me angry. They named their product after the Great Library of Alexandria. They call this product a library, but it is really iTunes without being iTunes.
They call it a decentralized library which allows for publishing content, is censorship free. It doesn’t have a lot of content and even less free content, but could be used for free content. It isn’t used for that now. They used the word library because of the implication of storing as much as possible. It is more of an artistic clearing house, like iTunes, than a library
They want librarians to organize stuff, but they don’t have any librarians or metadata analysts working for them now.
There are a lot of paywalls and you pay with Bitcoin.

- Ethereum is a public blockchain platform with programmable transaction functionality. It provides a decentralized virtual machine that can execute peer-to-peer contracts using a cryptocurrency called Ether. (Wikipedia)
- The block chain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: maintenance of the block chain is performed by a network of communicating nodes running bitcoin software. Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications. Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes.:ch. 8 The block chain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin (amount), each network node stores its own copy of the block chain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the block chain, and quickly published to all nodes. This allows bitcoin software to determine when a particular bitcoin amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, the block chain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.:ch. 5 (Wikipedia)
- InterPlanetary File System (IPFS) is a content-addressable, peer-to-peer hypermedia distribution protocol. Nodes in the IPFS network form a distributed file system. IPFS is an open source project developed by Protocol Labs with help from the open source community. It was initially designed by Juan Benet. (Wikipedia)
