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This Gist has been replaced by the THORChain Ecosystem Community Guide accessible at https://tcecosystem.guide/.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

Edit: here you can find our research paper describing the protocol more in-depth.

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

Overview

Syncing an Ethereum node is largely reliant on latency and IOPS, I/O Per Second, of the storage. Budget SSDs will struggle to an extent, and some won't be able to sync at all. For simplicity, this page treats IOPS as a proxy for/predictor of latency.

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

The drive lists are ordered by interface and then by capacity and alphabetically by vendor name, not by preference. The lists are not exhaustive at all. @mwpastore linked a filterable spreadsheet in comments that has a far greater variety of drives and their characteristics. Filter it by DRAM yes, NAND Type TLC, Form Factor M.2, and desired capacity.

For size, 4TB is a very conservative choice. The smaller 2TB drive should last an Ethereum full node until at least sometime 2026, with the pre-merge history expiry scheduled for Ma

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.

SAS: Succinct Atomic Swap

Works today with [single signer ECDSA adaptor signatures][0], or with Schnorr + MuSig.
Other than the explanation below, there's also a diagram and a video.

 
Advantages:

• Requires merely two on-chain transactions for successful completion, as opposed to four
• Scriptless, and one of the chains doesn't need to support timelocks
• Can be used for efficient privacy swaps, e.g. [Payswap][1]
