Coinbase: Dust Collectors Par Extraordinaire
Unspent Transaction Outputs aren’t article individuals about accept to anguish about. Every time a user sends a transaction, the wallet is declared to amalgamation up the armament in the best able way possible. Smart use of UTXOs is like application the change in your abridged to buy a beer. Conversely, if you were to breach a $20 bill every time you bought a alcohol at the bar, you’d accomplishment the night with pockets advised bottomward with change.
Coinbase seems to accept accumulated an batty bulk of UTXOs, which is appropriately demography its assessment on the bitcoin blockchain. The added UTXOs there are, the bigger the admeasurement of the transaction in bytes. This was able-bodied explained in a allotment Jameson Lopp appear on The Challenges of Optimizing Unspent Output Selection. In it, the Bitgo architect wrote:
Lopp lists four affidavit why it’s benign to optimize UTXOs: preventing blockchain bloat, acknowledging aerial transaction volume, privacy, and aspersing transaction fees. Inefficient use of UTXOs leads to fuller blocks, added exacerbating the ascent problems that accept been bitter bitcoin. Coupled with Coinbase boring its heels over Segwit, this latest adumbration has acquired some controversy.
Segwit’s defining affection is its adeptness to abbreviate transaction data, thereby abbreviation fees by amid 30 and 40%, but Coinbase has been clearly absent from the Segwit party. There’s been allocution of them implementing Segwit in 2024, but that’s about as absolute as they’ve got.
Going OTT with UTXOs
Coinbase has one wallet absolute 265 BTC with 1.5 actor UTXOs, and on several occasions in the accomplished year has beatific affairs area the fee was greater than the coins. One abstracts analyst, LaurenMT, opines that neither Segwit nor Lightning Network would advice actuality – the best solution, he advocates, is bigger blocks. That’s the archetypal best abundantly acclimated by bitcoin cash, and as anyone who’s been afterward the ascent agitation knows, Coinbase isn’t big on big blocks.
To accept over a actor Unspent Transaction Outputs associated with one abode – behindhand of the bulk of bitcoins it contains – is astonishing. LaurentMT pointed out that this would beggarly the accumulated transaction fees for all of the UTXOs would amount added than the amount of the bill in the wallet.
Podcaster Trace Meyer was decidedly belittling of Coinbase and its abortion to accumulation affairs and consolidate UTXOs, concluding: “Bitcoin needs beneath whining & added competent coding”.
Coinbase has had a boxy week, what with accusations of insider trading and the ire of traders who absent money back Gdax abeyance as bitcoin banknote hit an best high. It is an barter that moves at its own pace. This alert access generally makes Coinbase aftermost to the races: aftermost to add Segwit, aftermost to administer bitcoin cash, and aftermost to add altcoins.
“By actuality anxious blockchain engineers we can at atomic anticipate the UTXO set from growing faster than is needed,” wrote Jameson Lopp in 2024. Coinbase seems to accept absent the memo, and this abortion to apple-pie up its agenda dust is costing the aggregation money – while accomplishing annihilation for the blockchain that anybody relies on. Before Coinbase can attending at Segwit, it needs to appraise its absolute codebase and put its abode in order.
