Burrow

Burrow is a proposal for a federated coinpool on top of hedgehog channels. The coinpool can have a bunch of cool properties:

• a single-honest-party assumption, so the federation can't rug any user unless the keyholders in the federation are all scoundrels

• users can onboard into the pool without an on-chain transaction (e.g. maybe you send in coins via lightning, or maybe another user gives you your first coins from within the pool)

• every onboarded user gets their own wallet interface with their own personal balance and Send/Receive buttons

Unnamed Noncustodial Inchoate Sidechains On Bitvm (Unisob)

I have an independent bitvm sidechain model that works without a federation. Instead, there is a "bridge operator" who assists with depositing money to the sidechain as well as with the "happy path" of withdrawing from the sidechain. In my version, you can withdraw even if the bridge operator ceases operations, because there is also a "sad path" that does not require his ongoing cooperation

the main idea is that when you want to deposit money onto the sidechain you should get a "withdrawal contract" from the bridge operator

the withdrawal contract is done in bitvm and it basically says, if you (the withdrawer) can provide a proof of a valid withdrawal request from the sidechain, the prover has up to X blocks to supply proof that he sent you your money on bitcoin

if he does not supply that proof, you may slash him and take the funds that way

This Gist has been replaced by the THORChain Ecosystem Community Guide accessible at https://tcecosystem.guide/.

All the same information is available there, albeit even more updated/recent. Additionally, there are multiple collaborators maintaining the new site, which should help improve the quality of the information.

zkCoins

zkCoins is a novel blockchain design with strong privacy and scalability properties. It combines client-side validation with a zero-knowledge proof system. The chain is reduced to a minimum base layer to prevent double spending. Most of the verification complexity is moved off-chain and communicated directly between the individual sender and recipient of a transaction. There are very few global consensus rules, which makes block validation simple. Not even a global UTXO set is required.

In contrast to zk-rollups there is no data availability problem, and no sequencer is required to coordinate a global proof aggregation. The protocol can be implemented as an additional layer contained in Bitcoin's blockchain (similar to RGB[^5] or Taro[^6]) or as a standalone sidechain.

The throughput scales to hundreds of transactions per second without sacrificing decentralization.

Design Principles

The core design principle is to *"use the chain for what the chain is good for, which is an immutable order

Overview

Syncing an Ethereum node is largely reliant on IOPS, I/O Per Second. Budget SSDs will struggle to an extent, and some won't be able to sync at all.

This document aims to snapshot some known good and known bad models.

For size, 4TB comes recommended as of mid 2024. The smaller 2TB drive should last an Ethereum full node until early 2025 or thereabouts, with crystal ball uncertainty. Remy wrote a migration guide to 4TB.

High-level, QLC and DRAMless are far slower than "mainstream" SSDs. QLC has lower endurance as well. Any savings will be gone when the drive fails early and needs to be replaced.

Silent Payments

Receive private payments from anyone on a single static address without requiring any interaction or extra on-chain overhead.

Update: This now has a BIP and WIP implementation

Overview

The recipient generates a so-called silent payment address and makes it publicly known. The sender then takes a public key from one of their chosen inputs for the payment, and uses it to derive a shared secret that is then used to tweak the silent payment address. The recipient detects the payment by scanning every transaction in the blockchain.
