Title: [discussion]A new form of consensus Post by: TheLivingcrypto on August 07, 2018, 09:12:38 AM Segregated Byzantine Agreement (SBA) is a privacy-orientated consensus mechanism. It departs from consensus mechanisms like PoW/PoS, which are poorly suited for privacy.
SBA uses existing ideas like Cryptograpic Sortition (lottery) and combines it with concepts like stealth time-locked transactions to implement simple but secure communication that can be audited. SBA makes use of a few different types of actors in the network to reach consensus.
A node that wishes to participate in the sortition (and become a Block Generation candidate)is first required to lock an arbitrary amount of tokens. Rewards In addition to finalizing a block onto the chain, Notaries are also responsible for a secondary procedure which generates the block rewards through a set of coin-base transactions, essentially minting new tokens. The block rewards, together with the provisioner’s ROI, will form the network’s inflation rate.

Why is it necessary to enter a node for Provisioners? In all, this is only one way to get proofable block which is no better than others.

Other blockchain platforms treat privacy as an all-or-nothing. They either provide complete anonymity or complete openness. Those pursuing the latter approach have a significant adoption problem, since they practically impose the broadcasting of transactions on open ledgers, even in the case of smart contract platforms. These transactions may very well be the object of sensitive topics such as the settlement of medical or legal bills, auction bids, wages or indeed, trade secrecy around supplier sources and pay rates. The former, like Monero, ZCash or Dash purposefully focus on being nothing more than a simple store-of-value, do not allow third parties to deploy their own brand of confidential services and are frawned upon by regulators. By solving a focused set of specific use-cases and allowing for the proper confidentiality for each case, this concept is aimed at reconciling privacy with regulatory compliance.

Title: Re: [discussion]A new form of consensus Post by: TheLivingcrypto on August 07, 2018, 11:16:28 AM What TPS could this reach? More than TPS, which is a meaningless measure when in presence of an adaptive block size, it makes more sense to speak about throughput. Early experimentation shows that it can achieve extreme throughput by propagating block and block hashes separately (and worry about consistency later, as reconciliation would be indeed a separate matter). In this case it would not be excluded a throughput roughly 10^2 that of Bitcoin. |
