Featured Twitter | A detailed article on 2019: What progress have been made by Bitcoin and Ethereum?


Bitcoin Optech and ehthub_io founder Anthony Sassano each released a review of the progress made in Bitcoin and Ethereum in 2019 on the same day. Compared to Anthony Sassano, which detailed the progress made by the Ethereum ecosystem in different branch directions such as development, financing, and DeFi, and said that 2019 is "a surprising year for Ethereum construction", Bitcoin Optech cited improvements from a technical perspective. And these improvements are not "revolutionary improvements".

1. Bitcoin Optech releases progress made in Bitcoin in 2019, saying there are no "revolutionary improvements "

Bitcoin Optech's technical team, Bitcoin Optech, released its 2019 annual review, which summarizes the technical improvements of Bitcoin from January to December 2019. For 2019 improvements, Bitcoin Optech describes them as "a series of incremental improvements" rather than "revolutionary improvements" . These improvements include: making hardware wallets more accessible (HWI), generalizing communication between wallets between multi- signature and contract use cases (descriptors, PSBTs, miniscript), enhancing consensus security (consensus cleanup soft fork), and simplifying Testing ( signet), eliminating unnecessary hosting (loop), making it easier to run nodes (assumeutxo), improving privacy and saving block space (taproot), simplifying lightning network implementation (anyprevout), and better managing charge spikes ( (CTV), reduce node bandwidth (erlay), keep user safety (watchtowers) when Lightning Network is offline , reduce the need for trust (reproducible builds), prevent theft (vaults), promote privacy (SNICKER), and better manage Lightning Network users Anchor outputs, and make Lightning Network payments more used (multipath payments).

Listed below are the single month improvements from January to December.


○ BIP127 Proof of reserves

Steven Roose proposes a standard format for an anonymous transaction reserve certificate that Bitcoin custodians can use to generate evidence that they control a certain amount of Bitcoin.


○ Bitcoin Core client compatible with HWI (Hardware Wallet Interface)

○ Miniscript

Proposed by Pieter Wuille. Miniscript makes it easier for different Bitcoin systems to collaboratively sign transactions, thereby significantly reducing integrated wallet front ends, Lightning Network nodes, coinjoin systems, multisig (multi-signature) wallets, consumer hardware wallets, industrial hardware signature modules (HSM), and other The amount of custom code required for software and hardware.

March: ○ Consensus cleanup soft fork proposal

Proposed by Matt Corallo. Eliminate potential problems in Bitcoin consensus code.

○ Signet

The Signet protocol allows the creation of a testnet in which all valid new blocks must be signed by a centralized party. Signet will be integrated into Lightning Network client C-Lightning.

○ Lightning Loop

Announced by Lightning Lab. An unmanaged solution is provided for users who want to withdraw some funds from the Lightning Network channel to UTXO on the chain without closing the channel.


○ Assume UTXO

Proposed by James O'Beirne. This will allow wallets and other software using full nodes to start receiving and sending transactions within minutes after starting a node, without having to wait for hours or days like a newly launched node now.

○ Trampoline payments

Proposed by Pierre-Marie Padiou. This is a method that allows lightweight Lightning Network nodes to outsource pathfinding work to heavyweight routing nodes.


○ Taproot

Proposed by Pieter Wuille. Taproot can significantly improve user privacy and the fungibility of coins, while also reducing the blockchain space used by multi-signature and contract use cases.


Proposed by Anthony Towns. Functionally similar to SIGHASH_NOINPUT of BIP118, they intentionally do not recognize the UTXO spent, so that the signature can spend any UTXO that its script can perform (for example, using the same public key).


Proposed by Jeremy Rubin. This could enable new technologies to enhance coinjoin-style privacy, support vaults that enhance security, or manage the cost of spenders when transaction rates spike.


○ Erlay and other point-to-point relay improvements

Erlay's paper was co-published by Gleb Naumenko, Pieter Wuille, Gregory Maxwell, Sasha Fedorova, and Ivan Beschastnikh. Erlay is a protocol used to relay unconfirmed transaction announcements between nodes. This protocol utilizes libminisketch-based set reconciliation to reduce notification bandwidth by 84%.

○ Watchtowers


○ Reproducible builds

Proposed by Carl Dong. In July, the Bitcoin Core project merged Carl Dong's proposal and added support for using a copyable version of GNU Guix's Bitcoin Core Linux binaries.


○ Vaults without covenants

Proposed by Bryan Bishop. A way to implement vaults on Bitcoin without using covenants. vault is a term used to describe a script that restricts an attacker from stealing funds even if the user's regular private key is obtained.



Proposed by Adam Gibson. This protocol proposes a new type of non-interactive coinjoin for the existing Bitcoin system.

○ Lightning Network Vulnerability

The vulnerability shows that, in some cases, it seems that every implementation cannot confirm that the channel funds transaction paid the correct script or the correct amount (or both). The Lightning Network specification has been updated to help avoid this problem in the future.


○ LN anchor outputs

Lightning Network developers made significant progress in October and November, addressing a long-standing problem of ensuring that users can always close their channels without undue delay.


○ Bech32 mutability

○ Removed OpenSSL from Bitcoin Core. Removing OpenSSL promises to reduce the frequency of future vulnerabilities.

○ Bitcoin Core removed support for BIP70 payment protocol.


○ Multipath payments

User-friendly improvements. This allows users to use multiple channels to consume or collect money at once, making it possible to use the entire off-chain balance or to obtain the full capacity through a single payment (within certain security restrictions).

3. Ethereum 2020 forecast: VCs will buy ETH aggressively

Just as Bitcoin and Ethereum each released their 2019 review, DTC Capital founder Spencer Noon published his predictions for ETH 2020:

My prediction for Ethereum in 2020: VC buys ETH . why?

They had previously invested in Layer 1:

New Layer 1 investment: wait and see phase

Dapp on Ethereum: bullish all the way

Other Dapps on Layer 1: Currently 0

ETH Dapp Highlights: DeFi

DeFi Dapp Success Story: Average Total Asset Management Increased

Investor Trends: Active Participation

No.1 DeFi Collateral: ETH

Net New Buy: ETH

The Block founder Mike Dudas took over the topic and published his 2020 Ethereum prediction:

My forecast for 2020:

In the next 12-24 months, ETH is in a transition period .

A lot of activity, memes, signs of life and growth.

A lot of VCs optimistic about 2020 put their money into Open Finance (Open Finance) / DeFi, dApps (yes), "enterprise" Ethereum, in order to obtain a better consumer experience.

The return on ETH itself is disappointing.

I was impressed by the ambitions of the team building on Ethereum.

However, the fact remains that only very few people own $ ETH, and that surprisingly few people use ETH in any application. At the same time, at least 10 million people own $ BTC.

How do you rate Bitcoin and Ethereum in 2019? Welcome message.




4. Some interesting data for Bitcoin 2019

Casa CTO Jameson Lopp listed some data of Bitcoin in 2019, including SegWit usage trends, miner transaction cost trends, and Bitcoin transaction amount trends:

The year of SegWit? 2019! This year, Bitcoin transactions spent another 20% on SegWit output, and now most transactions spend SegWit output. https://segwit.space/

Bitcoin address reuse ( referring to an address being used in multiple Bitcoin transactions ) is a bad privacy practice, which has declined in the second half of 2019 after a 12% increase over the past 18 months. https://oxt.me/charts

The transaction fees charged by bitcoin miners have fluctuated significantly in 2019, with an average of $ 100,000 per day during peacetime, but reaching $ 2 million per day during busy times . The peak cost in 2019 is still less than 10% of the maximum cost days in 2018. https://blockchain.com/charts/transaction-fees-usd

The daily Bitcoin transaction volume on the chain reaches 20 billion U.S. dollars / day , which is 10 times the initial amount in 2019. It is now about two times, roughly reflecting exchange rate changes. https://coinmetrics.io/charts/#assets=btc_log=false_left=TxTfrValUSD_right=PriceUSD_zoom=1546120512000,1577656512000

Output of Bitcoin OP_RETURN (data anchor) created in 2014-2019:

2014: 13,000

2015: 655,000

2016: 1,040,000

2017: 2,253,000

2018: 6,750,000

2019: 28,200,000


OP_RETURN is a script operation code that marks transaction information as invalid and can be used to carry data other than transaction information . Back in 2013, different players in the Bitcoin ecosystem were trying to incorporate information into transactions in order to take advantage of the irreversibility of the blockchain. Many members of the Bitcoin community believe that using OP_RETURN is irresponsible, in part because Bitcoin is designed to provide a record of financial transactions, not arbitrary data records.




5. Industry News

a.Beam will perform the first halving at block height 525600 on January 4, 2020. After the next halving, the BEAM mined in each block will be halved from 80 to 40.

b.Chainlink (decentralized oracle network) and Loopring (decentralized exchange agreement) announced the cooperation of multiple Oracle integrations through Loopring's v3 zkRollup DEX protocol. This will allow Loopring DEX to scale off-chain with zkRollups, but still use economic incentives to stay safe.

c. Virgil Griffith, an Ethereum research scientist accused of assisting North Korea in understanding blockchain and cryptocurrencies, was denied bail.

d. Huobi launches fiat-cryptocurrency portal for its Indonesian subsidiary. Huobi Indonesia's services will use Indonesian Rupiah (IDR) and tether (USDT). Indonesian users can deposit Indonesian rupiah through Huobi and convert it into U.S. dollars to trade more than 250 cryptocurrencies supported by their global platform.

e. Bloomberg reported that Craig Wright, a controversial figure who had been ordered by a judge to surrender his 3 billion bitcoin holdings, said he may not be able to enforce the order in the near future.
