state/payment channel solution has been proposed by various parties.

Bitcoin

• Lightning Network. White paper by Joseph Poon
• implemented in GO
• finally the demo video

Ethereum

• The most well-known is Raiden Network

• Joseph Poon talks about some consideration of designing state channel in Ethereum. At the time he was speaking, the equivlent project Lightening Network, proposed two year ago, had not launched yet.

• Jeff Coleman talks a lot about state channel

  • talk 1
  • talk 2
  • talk 3

• Ameen Soleimani talks a lot about state channel.

  • talk 1
  • talk 2
  • he analyzed Joseph Pooh's Plasma

• Vitalik funds Liam Horne to work on the long-wait topic -- general state channel. Please note that the co-author is Jeff Coleman.

• Layer 2 scaling solution survey

Arguments

• mathematical proof that the lightning network cannot be a decentralized bitcoin scaling solution by Jonald Fyookball
• continued discussion on why lightning network cannot scale by Jonald Fyookball
• lightning network will likely fail due to several possible reasons written by bitcoin cash supporter.
• simulating a decentralized lightning network with 10 million users
• why lightning and raiden networks will not work
• very well written https://blog.bitmex.com/the-lightning-network

plasma Historically, many people believe that the blockchain is best applied towards transactional payments as a gross settlement system. However, it’s understood that a gross settlement system has difficulty scaling. Net settled designs such as the Lightning Network, a payment channel network, changes the structure to allow for nearly unlimited payments between participants. Transactional capacity is increased dramatically as channels are net-settled on the blockchain. Payments can be routed across a network of these channels. This structure additionally allows for effectively instantaneous payments. This is instrumental for not only payments which require a high degree of time sensitivity, but also for contracts as well.

• net settlement: 淨額結算
• gross settlement: 總額結算

2.3 Plasma Blockchain

• We attempt to replicate the incentives around the Nakamoto Consensus, but using Proof-of-Stake bonds
• there is incredible incentive to minimize block withholding attacks. -- What is block withholding attacks?
• initial discussion on reddit

Karl's explain

• video
• slide

Incredibly high amount of transactions can be committed on this Plasma chain with minimal data hitting the root blockchain. Any participant can transfer funds to anyone, including transfers to participants not in the existing set of participants. These transfers can pay into and withdraw (with some time delay and proofs) funds in the root blockchain’s native coin(s)/token(s). sounds good. Does this mean that a new participant can receive fund(ex. new member gift?) without spending any transaction fee?

We construct an interactive game whereby the exiting party attests to a bitmap of participants ledger outputs arranged in an UTXO model which requests a withdrawal. Anyone on the network can submit an alternate bonded proof which attests whether any funds have already been spent. In the event this is incorrect, anyone on the network can attest to fraudulent behavior and slash the bonds to roll back the attestation.
