What's the Going Rate for a Tutor?
https://patch.com/new-york/parkslope/whats-the-going-rate-for-a-tutor-parkslope
A high school student might charge as little as $10 per hour, while an experienced tutor in the country's most expensive market, Manhattan, is considered reasonable at $85 to $150 per hour, with Ivy League graduates earning $200 per hour or more.
Tutors don't have to live locally. Through services such as Tutorspreeand UniversityTutor, you can arrange one-on-one instruction through the Internet. Rates depend on the tutor selected, commonly ranging from $20 to $50 per session. Tutor.com connects kids to tutors online anytime of the day or night for roughly $40 per hour.
Another option is to take your child to a tutoring center like Sylvan Learning ($55 per hour) or Mathnasium ($75 per hour based on 10 sessions).

Lumini, Alex Lebed
Lumini - designed to combine Beam and Ethereum It can basically swap ERC20 assets into privacy wrapped version of it.
The launch of a private cryptocurrency Beam based on the MimbleWimble protocol

The Beam team is also working on two additional projects – Project Lumini and Beam Lightning. The first is designed to combine Beam and Ethereum, the second – integrates the Beam with the Lightning Network.
Remember that Grin developers also received financial support in December 2018 – this was made possible thanks to investments of $ 2.1 million from PayPal co-founder Peter Thiel and Digital Currency Group Barry Silbert in the Layer1 platform. The latter is working on creating an infrastructure that will ensure the further growth of Grin. The launch of the project is expected on 15 January.

Two Scalable BlockDAG protocols

Abstract
In 2008 Satoshi Nakamoto invented the basis for blockchain based distributed ledgers. The core concept of this system is an open and anonymous network of nodes, or miners, which together maintain a public ledger of transactions. The ledger takes the form of a chain of blocks, the blockchain, where each block is a batch of new transactions collected from users. One primary problem with Satoshi’s blockchain is its highly limited scalability. The security of Satoshi’s longest chain rule, more generally known as the Bitcoin protocol, requires that all honest nodes be aware of each other’s blocks very soon after the block’s creation. To this end, the throughput of the system is artificially suppressed so that each block fully propagates before the next one is created, and that very few “orphan blocks” that fork the chain be created spontaneously. In this paper we present PHANTOM, a PoW based protocol for a permissionless ledger that generalizes Nakamoto’s blockchain to a direct acyclic graph of blocks (blockDAG). PHANTOM includes a parameter k that controls the level of tolerance of the protocol to blocks that were created concurrently, which can be set to accommodate higher throughput. It thus avoids the security-scalability tradeoff which Satoshi’s protocol suffers from. PHANTOM uses a greedy algorithm on the blockDAG to distinguish between blocks mined properly by honest nodes and those that created by non-cooperating nodes who chose to deviate from the mining protocol. Using this distinction, PHANTOM provides a robust total order on the blockDAG in a way that is eventually agreed upon by all honest nodes.
