IOTA is a distributed ledger that rellies on spread validation of transactions instead of blocks. Instead of having miners confirming blocks of transactions, each participant issuing a transaction must approve 2 past transactions. Thus consensus is reached by destributed, active users. This data structure, based on Directed Acyclic Graph forms the ledger dubbed “Tangle”. As described in detail in Serguei Popov’s white paper.Continue reading

Tezos: A new digital commonwealth
Tezos a generic and self-amending crypto-ledger. Tezos can instantiate any blockchain based ledger. The operations of a regular blockchain are implemented as a purely functional module abstracted into a shell responsible for network operations, and allows creating governance rules for stakeholders to approve of protocol upgrades that are then automatically deployed on the network.
EOS White Paper
The EOS.IO software introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved by creating an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across hundreds of CPU cores or clusters. The resulting technology is a blockchain architecture that scales to millions of transactions per second, eliminates user fees, and allows for quick and easy deployment of decentralized applications.Continue reading

BRR – CME Bitcoin Reference Rate Methodology
Summary Description
The CME CF Bitcoin Reference Rate (“BRR”) is a daily reference rate of the U.S. Dollar price of one bitcoin as of 4:00 p.m. London time. It is representative of the bitcoin trading activity on Constituent Exchanges and is geared towards resilience and replicability.Continue reading
BRTI – CME Bitcoin Real Time Index Methodology
Summary Description
The CME CF Bitcoin Real Time Index (“BRTI”) is a real time index of the U.S. Dollar price of one bitcoin. It is representative of current bids and offers of market participants to buy or sell bitcoin on Constituent Exchanges. It is geared towards timeliness and represents an unbiased estimator of the instantaneous bitcoin price.Continue reading
Lumino whitepaper
Lumino Transaction Compression Protocol (LTCP)
by Sergio Demian Lerner, Chief Scientist RSK Labs
“…The critical insight behind Lumino compression is delta compression of selected fields, from a previous referenced transaction and the aggregate signing of previous transactions, so previous signatures can be disposed. Delta compression is done by allowing each transaction to refer to a previous transaction from the same owner, which is used as a template. Any field can be overridden, and unmodified fields are copied intact.
Monero: Ring Confidential Transactions
The Monero v0.10.0 was recently released. It features major performance improvements, space savings gains for the blockchain, and the initial release of Ring Confedential Transactions, that are currently live on the testnet.

Bitcoin Lightning Paper
The Lightning Network is a proposed solution to bitcoin scalability, dependent upon the underlying technology of the blockchain. By using real Bitcoin/blockchain transactions and using its native smart-contract scripting language, it is possible to create a secure network of participants which are able to transact at high volume and high speed.

“…Rootstock (RSK), a smart-contract platform that incorporates a Turing Complete Virtual Machine to Bitcoin. It also provides other enhancement to the network such as faster transactions and better scalability, features that we also believe will enable new usage scenarios.Continue reading
Interledger connectors protocol
Interledger is an open protocol suite for sending payments across different ledgers. Like routers on the Internet, connectors route packets of money across independent payment networks. The open architecture and minimal protocol enable interoperability for any value transfer system. Interledger is not tied to any one company, blockchain, or currency.

Stellar payment protocol
Stellar is a open source consensus protocol, forked out of Ripple.
White paper by David Mazières from Stellar Development Foundation “introduces a new model for consensus called federated Byzantine agreement (FBA). (…) and Stellar Consensus Protocol (SCP), a construction for FBA. Like all Byzantine agreement protocols, SCP makes no assumptions about the rational behavior of attackers. Unlike prior Byzantine agreement models, which presuppose a unanimously accepted membership list, SCP enjoys open membership that promotes organic network growth. Compared to decentralized proof of-work and proof-of-stake schemes, SCP has modest computing and financial requirements, lowering the barrier to entry and potentially opening up financial systems to new participants”
